‘Reassuring’ follow-up validates radiation strategy for early breast cancer
SAN DIEGO –
The follow-up analysis of the 2,016-subject IMPORT LOW study found that 10-year overall survival rates were 87.8% (95% confidence interval, 84.9-90.1) for a full-breast radiation group, 87.2% (95% CI, 84.3-89.6) for a reduced-dose group, and 90.3% (95% CI, 87.7-92.4) in a partial-breast group. Breast cancer radiotherapy specialist Anna Kirby, MB, MD (Res), MA, of the Royal Marsden and Institute of Cancer Research, London, reported the results at the annual meeting of the American Society for Radiation Oncology.
Ipsilateral breast tumor relapse was also similar in the three groups at the 10-year mark at 2.8% (95% CI, 1.8-4.5), 1.9% (95% CI, 1.1-3.4), and 2.8% (95% CI, 1.7-4.5), respectively. Moderate/marked adverse effects were deemed to be low.
Dr. Kirby said the new findings are not “practice-changing.” However, “this complementary data supporting the change in practice that happened in the UK and elsewhere following the publication back in 2017.”
The findings are “reassuring,” breast cancer radiology specialist Robert W. Mutter, MD, of the Mayo Clinic, Rochester, Minn., said in an interview after reviewing the study findings. While the outcomes and adverse events are similar between the groups, “partial-breast irradiation is attractive because it exposes less normal tissue such as the heart and lungs than whole-breast irradiation. This could lead to fewer side effects for patients later in life at a population level. Partial-breast irradiation should be considered a standard of care in selected patients.”
In a presentation at ASTRO, Dr. Kirby provided background about the motivation for the study. It was clear that radiotherapy reduces local recurrence by up to two-thirds in early breast cancer, she said. “But in a population with excellent prognosis, this translates into relatively small absolute benefits from radiotherapy for many of our lower-risk patients,” she said. “All patients treated are at risk of radiotherapy side effects, and these become the main hazard for many women. Radiotherapy that’s focused on the part of the breast that contained the tumor – the so-called tumor bed – may reduce the long-term complications from radiotherapy, particularly in the breast, and potentially in the heart and lung, whilst hopefully maintaining low local recurrence rates.”
The initial 5-year study was a randomized, multicenter, phase III trial of patients ≥ age 50 in the United Kingdom who were tracked since recruitment in 2007-2010 (median age, 63). All had undergone breast conservation surgery. The patients were assigned to the control group (n = 674, 40 Gy), reduced-dose (n = 673, 40 Gy) and partial-breast (n = 669, 40 Gy to partial breast only) in 15 daily treatment fractions. The initial results, published in The Lancet, reported noninferiority for both reduced-dose and partial-breast radiotherapy. Adverse effects were similar in the three groups except for change in breast appearance, which was better in partial-breast therapy vs. whole-breast, and breast harder or firmer, which was better in both partial- and reduced-dose groups vs. whole-breast.
Dr. Mutter described the IMPORT LOW trial as “a practice-changing study.”
The trial was unique since both the whole-breast and partial-breast arms received the same dosing schedule, he said, which “enables an unbiased assessment of the impact of target volume on treatment outcomes.” This contrasts “with other partial-breast irradiation studies where a different dosing schedule was employed for whole-breast and partial-breast irradiation.”
The new analysis tracked patients for a median of 121 months. “There is no difference in local recurrence rate across the three arms,” Dr. Kirby said. There were no differences in overall survival, breast cancer or cardiac deaths, she added, and “neither was there any difference in the time to any moderate or marked clinician-assessed breast normal tissue endpoint.”
Heart and lung outcomes may improve over time in the lower-dose groups because of less radiation exposure, “but we haven’t shown that yet with this data set.”
Dr. Mutter cautioned that “the results of this trial may not necessarily be extrapolated to other partial-breast irradiation techniques that treat a much smaller volume of breast tissue such as intracavitary brachytherapy and intraoperative radiotherapy. Whether these same excellent outcomes can be achieved with smaller treatment volumes is an area for further investigation.”
Funding information was not provided; the initial study was funded by Cancer Research UK. Dr. Kirby discloses travel costs paid by European Society of Radiotherapy and Oncology, and other authors have various disclosures including relationships with companies such as Pfizer, Seagen, AstraZeneca, Eli Lilly, Bayer, and Janssen.

Optimal antiplatelet regimen in ‘bi-risk’ ACS?
Among “bi-risk” patients with acute coronary syndrome (ACS) who received a stent and completed 9-12 months of dual-antiplatelet therapy (DAPT), those who de-escalated therapy to clopidogrel alone as opposed to continuing on clopidogrel and aspirin for 9 months had 25% less bleeding without increased ischemic risk.
The findings are from the OPT-BIRISK trial in more than 7,700 patients in China deemed “bi-risk” because they had both a high risk of clinically relevant bleeding and a high risk of major adverse cardiac and cerebral events (MACCE).
Yaling Han, MD, from General Hospital of Northern Theater Command in Shenyang, China, presented the trial in a hotline session at the annual congress of the European Society of Cardiology.
Dr. Han said in an interview.
She acknowledged that the findings may not be generalizable to non-Asian cohorts. Also, these patients were event-free after 9 months on DAPT, so they were relatively stable. Moreover, the finding that clopidogrel monotherapy was superior to DAPT for MACCE is only hypothesis-generating.
Renato D. Lopes, MD, PhD, Duke University, Durham, N.C., the assigned discussant at the session, congratulated the authors “for an important trial in the understudied East Asian population. The OPT-BIRISK trial adds information to the complex puzzle of antithrombotic therapy after ACS,” he said.
However, he brought up a few points that should be taken into consideration when interpreting this trial, including the ones noted by Dr. Han.
In an interview, Dr. Lopes cautioned that OPT-BIRISK tested an antiplatelet strategy “in challenging patients at increased risk for bleeding and ischemic events, but I don’t think we can say this is truly a high-risk population.” Invited to reply, Dr. Han conceded that these patients constituted a relatively low-risk subset of bi-risk patients.
Double-edged sword
“Antiplatelet therapy is a double-edged sword: it reduces ischemic risk but increases bleeding risk. Optimal antiplatelet therapy for bi-risk ACS patients remains a clinical challenge, and unsolved problem for the cardiovascular physician,” Dr. Han said in a press briefing.
The rationale and design of OPT-BIRISK were published in the American Heart Journal in 2020.
Between February 2018 and December 2020, the researchers enrolled and randomly assigned 7,758 bi-risk patients in 101 centers in China who had completed 9-12 months of DAPT (aspirin plus either clopidogrel or ticagrelor) after drug-eluting stent implantation for ACS.
The patients were randomly assigned to receive either clopidogrel plus aspirin or clopidogrel plus placebo for 9 months, followed by 3 months of aspirin.
The primary endpoint was clinically relevant Bleeding Academic Research Consortium (BARC) types 2, 3, or 5 bleeding, at 9 months after randomization.
Key secondary endpoints were MACCE (all-cause mortality, MI, stroke, or clinically driven revascularization), individual components of MACCE, any bleeding, and stent thrombosis at 9 months after randomization.
The patient criteria for having bi-risk ACS were:
- < 65 years old with at least one high-bleeding risk criterion and at least one high-ischemia risk criterion.
- 65-78 years old with at least one high-bleeding risk criterion or at least one high-ischemia risk criterion.
- > 75 years old.
The high bleeding risk criteria were female gender, iron deficiency anemia, stroke, taking a type 2 diabetes medication, and chronic kidney disease.
The high ischemic risk criteria included troponin-positive ACS, previous stent thrombosis, previous CV events (MI, stroke, peripheral artery disease [PAD], percutaneous coronary intervention [PCI]), on a type 2 diabetes medication, chronic kidney disease, and certain lesion characteristics.
The patients had a mean age of about 65 years and 41% were female.
About half (52%) had type 2 diabetes, 18% had previous MI, and 15% had previous ischemic stroke. The ACS was mainly unstable angina (62%), followed by NSTEMI (17%) or STEMI (21%).
The patients had a mean high ischemic risk criteria of 3.2 and a mean high bleeding risk criteria of 1.4.
The initial DAPT treatment was aspirin and clopidogrel in three quarters of the patients and aspirin and ticagrelor in the remaining patients.
At 9 months, the primary endpoint of BARC type 2-5 bleeding occurred in 2.5% of patients in the clopidogrel plus placebo group and in 3.3% of patients in the clopidogrel plus aspirin group (hazard ratio, 0.75; 95% confidence interval, 0.57-0.97, P = .03).
“The bleeding results are not surprising,” Dr. Lopes said. Monotherapy vs. DAPT will cause less bleeding, Dr. Han agreed.
At 9 months, MACCE occurred in 2.6% of patients in the clopidogrel plus placebo group and in 3.5% of patients in the clopidogrel plus aspirin group (HR, 0.74; 95% CI, 0.57-0.96, P = .02).
Interpreting this latter finding as “reduced risk” of MACCE “is a stretch,” Dr. Lopes cautioned.
A potential explanation for this finding in the trial is that in the comparison group (aspirin plus clopidogrel), when patients had bleeding, they might have stopped all antiplatelet therapy, and this may have led to more ischemic events, he speculated.
“The observed reduction in MACCE is plausible,” Dr. Han said. “However, according to study protocol, we assumed that clopidogrel monotherapy would be noninferior to DAPT on the risk of MACCE. The superiority of clopidogrel alone vs. DAPT on MACCE should therefore be hypothesis-generating.”
“The increased rate of MACCE in the clopidogrel plus aspirin group was surprising,” she said in a press release from the ESC, “and may be because hemorrhagic events, which are more common with ongoing DAPT, could be associated with an adrenergic state with increased platelet aggregation due to hypotension, remedial procedures to treat bleeding, and the cessation of anti-ischemic medications.”
A low-risk subset of bi-risk patients, commonly seen in clinical practice
At the time of the index ACS, more than 60% of the patients had unstable angina, Dr. Lopes observed, “and we know these patients are lower risk.” Also, more than 1,000 of the patients did not have at least one high-risk factor for bleeding or ischemia. Moreover, these patients had not had any clinical events in the past 9-12 months on DAPT, “so they were not truly high risk when they were randomized.
“Patients aged 75 years and above are definitely bi-risk (even without any bleeding/ischemic criteria), especially post ACS, according to much literature,” Dr. Han said.
“Although patients met the bi-risk criteria for increased ischemia and bleeding at the time of index ACS and PCI, they were free from major events for at least 6 months on DAPT, thus constituting a relatively low-risk subset of bi-risk patients,” she conceded.
“Nonetheless, these patients (mean age nearly 65 years, 41% female, 52% diabetes, 18% MI history and 15% ischemic stroke history in bi-risk study) represent a large cohort seen in clinical practice,” she said. And “according to a real-world, nationwide registry from China (the OPT-CAD study), unstable angina accounted for about 50% of all ACS patients.”
There have been more data with shorter times for stopping aspirin, so it’s difficult to reconcile those studies with data from OPT-BIRISK, according to Dr. Lopes.
For example, the 2019 TWILIGHT study in patients undergoing PCI at high risk for bleeding showed that it seems to be safe to stop aspirin after 3 months and continue ticagrelor, without an increase in ischemic events.
“The question is almost in the wrong time,” he said, noting that the field is moving in the direction of stopping aspirin earlier, according to five or six recently published trials.
It is hard to generalize from an Asian population, he agreed. “In the U.S., we have other data that suggests that for high-risk patients, you can stop aspirin earlier than 9 months. That’s what most practices are doing.”
“When you look at different drugs, different doses, different duration,” Dr. Lopes summarized, “you have thousands of different permutations,” for antiplatelet therapy strategies. “Every time we have some data in large studies it adds a piece to the puzzle.”
The study was funded by the National Key Research and Development Project in China, and by a grant from Sanofi-Aventis. Dr. Han reports no relevant financial relationships. Disclosures for the other coauthors can be found with the original article.

The patients were randomly assigned to receive either clopidogrel plus aspirin or clopidogrel plus placebo for 9 months, followed by 3 months of aspirin.
The primary endpoint was clinically relevant Bleeding Academic Research Consortium (BARC) types 2, 3, or 5 bleeding, at 9 months after randomization.
Key secondary endpoints were MACCE (all-cause mortality, MI, stroke, or clinically driven revascularization), individual components of MACCE, any bleeding, and stent thrombosis at 9 months after randomization.
The patient criteria for having bi-risk ACS were:
- < 65 years old with at least one high-bleeding risk criterion and at least one high-ischemia risk criterion.
- 65-78 years old with at least one high-bleeding risk criterion or at least one high-ischemia risk criterion.
- > 75 years old.
The high bleeding risk criteria were female gender, iron deficiency anemia, stroke, taking a type 2 diabetes medication, and chronic kidney disease.
The high ischemic risk criteria included troponin-positive ACS, previous stent thrombosis, previous CV events (MI, stroke, peripheral artery disease [PAD], percutaneous coronary intervention [PCI]), on a type 2 diabetes medication, chronic kidney disease, and certain lesion characteristics.
The patients had a mean age of about 65 years and 41% were female.
About half (52%) had type 2 diabetes, 18% had previous MI, and 15% had previous ischemic stroke. The ACS was mainly unstable angina (62%), followed by NSTEMI (17%) or STEMI (21%).
The patients had a mean high ischemic risk criteria of 3.2 and a mean high bleeding risk criteria of 1.4.
The initial DAPT treatment was aspirin and clopidogrel in three quarters of the patients and aspirin and ticagrelor in the remaining patients.
At 9 months, the primary endpoint of BARC type 2-5 bleeding occurred in 2.5% of patients in the clopidogrel plus placebo group and in 3.3% of patients in the clopidogrel plus aspirin group (hazard ratio, 0.75; 95% confidence interval, 0.57-0.97, P = .03).
“The bleeding results are not surprising,” Dr. Lopes said. Monotherapy vs. DAPT will cause less bleeding, Dr. Han agreed.
At 9 months, MACCE occurred in 2.6% of patients in the clopidogrel plus placebo group and in 3.5% of patients in the clopidogrel plus aspirin group (HR, 0.74; 95% CI, 0.57-0.96, P = .02).
Interpreting this latter finding as “reduced risk” of MACCE “is a stretch,” Dr. Lopes cautioned.
A potential explanation for this finding in the trial is that in the comparison group (aspirin plus clopidogrel), when patients had bleeding, they might have stopped all antiplatelet therapy, and this may have led to more ischemic events, he speculated.
“The observed reduction in MACCE is plausible,” Dr. Han said. “However, according to study protocol, we assumed that clopidogrel monotherapy would be noninferior to DAPT on the risk of MACCE. The superiority of clopidogrel alone vs. DAPT on MACCE should therefore be hypothesis-generating.”
“The increased rate of MACCE in the clopidogrel plus aspirin group was surprising,” she said in a press release from the ESC, “and may be because hemorrhagic events, which are more common with ongoing DAPT, could be associated with an adrenergic state with increased platelet aggregation due to hypotension, remedial procedures to treat bleeding, and the cessation of anti-ischemic medications.”
A low-risk subset of bi-risk patients, commonly seen in clinical practice
At the time of the index ACS, more than 60% of the patients had unstable angina, Dr. Lopes observed, “and we know these patients are lower risk.” Also, more than 1,000 of the patients did not have at least one high-risk factor for bleeding or ischemia. Moreover, these patients had not had any clinical events in the past 9-12 months on DAPT, “so they were not truly high risk when they were randomized.
“Patients aged 75 years and above are definitely bi-risk (even without any bleeding/ischemic criteria), especially post ACS, according to much literature,” Dr. Han said.
“Although patients met the bi-risk criteria for increased ischemia and bleeding at the time of index ACS and PCI, they were free from major events for at least 6 months on DAPT, thus constituting a relatively low-risk subset of bi-risk patients,” she conceded.
“Nonetheless, these patients (mean age nearly 65 years, 41% female, 52% diabetes, 18% MI history and 15% ischemic stroke history in bi-risk study) represent a large cohort seen in clinical practice,” she said. And “according to a real-world, nationwide registry from China (the OPT-CAD study), unstable angina accounted for about 50% of all ACS patients.”
There have been more data with shorter times for stopping aspirin, so it’s difficult to reconcile those studies with data from OPT-BIRISK, according to Dr. Lopes.
For example, the 2019 TWILIGHT study in patients undergoing PCI at high risk for bleeding showed that it seems to be safe to stop aspirin after 3 months and continue ticagrelor, without an increase in ischemic events.
“The question is almost in the wrong time,” he said, noting that the field is moving in the direction of stopping aspirin earlier, according to five or six recently published trials.
It is hard to generalize from an Asian population, he agreed. “In the U.S., we have other data that suggests that for high-risk patients, you can stop aspirin earlier than 9 months. That’s what most practices are doing.”
“When you look at different drugs, different doses, different duration,” Dr. Lopes summarized, “you have thousands of different permutations,” for antiplatelet therapy strategies. “Every time we have some data in large studies it adds a piece to the puzzle.”
The study was funded by the National Key Research and Development Project in China, and by a grant from Sanofi-Aventis. Dr. Han reports no relevant financial relationships. Disclosures for the other coauthors can be found with the original article.

FROM ESC CONGRESS 2023
Does an elevated TSH value always require therapy?
Thyroxine and L-thyroxine are two of the 10 most frequently prescribed medicinal products. “One large health insurance company ranks thyroid hormone at fourth place in the list of most-sold medications in the United States. It is possibly the second most commonly prescribed preparation,” said Joachim Feldkamp, MD, PhD, director of the University Clinic for General Internal Medicine, Endocrinology, Diabetology, and Infectious Diseases at Central Hospital, Bielefeld, Germany, at the online press conference for the German Society of Endocrinology’s hormone week.
The preparation is prescribed when the thyroid gland produces too little thyroid hormone. The messenger substance thyroid-stimulating hormone (TSH) is used as a screening value to assess thyroid function. An increase in TSH can indicate that too little thyroid hormone is being produced.
“But this does not mean that an underactive thyroid gland is hiding behind every elevated TSH value,” said Dr. Feldkamp. Normally, the TSH value lies between 0.3 and 4.2 mU/L. “Hypothyroidism, as it’s known, is formally present if the TSH value lies above the upper limit of 4.2 mU/L,” said Dr. Feldkamp.
Check again
However, not every elevated TSH value needs to be treated immediately. “From large-scale investigations, we know that TSH values are subject to fluctuations,” said Dr. Feldkamp. Individual measurements must therefore be taken with a grain of salt and almost never justify a therapeutic decision. Therefore, a slightly elevated TSH value should be checked again 2-6 months later, and the patient should be asked if they are experiencing any symptoms. “In 50%-60% of cases, the TSH value normalized at the second checkup without requiring any treatment,” Dr. Feldkamp explained.
The TSH value could be elevated for several reasons:
- Fluctuations depending on the time of day. At night and early in the morning, the TSH value is much higher than in the afternoon. An acute lack of sleep can lead to higher TSH values in the morning.
- Fluctuations depending on the time of year. In winter, TSH values are slightly higher than in the summer owing to adaptation to cooler temperatures. Researchers in the Arctic, for example, have significantly higher TSH values than people who live in warmer regions.
- Age-dependent differences. Children and adolescents have higher TSH values than adults do. The TSH values of adolescents cannot be based on those of adults because this would lead to incorrect treatment. In addition, TSH values increase with age, and slightly elevated values are initially no cause for treatment in people aged 70-80 years. Caution is advised during treatment, because overtreatment can lead to cardiac arrhythmias and a decrease in bone density.
- Sex-specific differences. The TSH values of women are generally a little higher than those in men.
- Obesity. In obesity, TSH increases and often exceeds the normal values usually recorded in persons of normal weight. The elevated values do not reflect a state of hypofunction but rather the body’s adjustment mechanism. If these patients lose weight, the TSH values will drop spontaneously. Slightly elevated TSH values in obese people should not be treated with thyroid hormones.
The nutritional supplement biotin (vitamin H or vitamin B7), which is often taken for skin, hair, and nail growth disorders, can distort measured values. In many of the laboratory methods used, the biotin competes with the test substances used. As a result, it can lead to falsely high and falsely low TSH values. At high doses of biotin (for example, 10 mg), there should be at least a 3-day pause (and ideally a pause of 1 week) before measuring TSH.
Hasty prescriptions
“Sometimes, because of the assumption that every high TSH value is due to sickness-related hypothyroidism, thyroid hormones can be prescribed too quickly,” said Dr. Feldkamp. This is also true for patients with thyroid nodules due to iodine deficiency, who are often still treated with thyroid hormones.
“These days, because we are generally an iodine-deficient nation, iodine would potentially be given in combination with thyroid hormones but not with thyroid hormones alone. There are lots of patients who have been taking thyroid hormones for 30 or 40 years due to thyroid nodules. That should definitely be reviewed,” said Dr. Feldkamp.
When to treat?
Dr. Feldkamp does not believe that standard determination of the TSH value is sensible and advises that clinicians examine patients with newly occurring symptoms, such as excess weight, impaired weight regulation despite reduced appetite, depression, or a high need for sleep.
If there are symptoms, the thyroid function must be clarified further. “This includes determination of free thyroid hormones T3 and T4; detection of antibodies against autologous thyroid tissue such as TPO-Ab [antibody against thyroid peroxidase], TG-Ab [antibody against thyroglobulin], and TRAb [antibody against TSH receptor]; and ultrasound examination of the metabolic organ,” said Dr. Feldkamp. Autoimmune-related hypothyroidism (Hashimoto’s thyroiditis) is the most common cause of an overly high TSH level.
Treatment should take place in the following situations:
- In young patients with TSH values greater than 10 mU/L;
- In young (< 65 years) symptomatic patients with TSH values of 4 to less than 10 mU/L;
- With elevated TSH values that result from thyroid surgery or radioactive iodine therapy;
- In patients with a diffuse enlarged or severely nodular thyroid gland
- In pregnant women with elevated TSH values.

Choosing which biologic to prescribe for psoriasis
CARLSBAD, CALIF. –
“When you look at the list of options it can be confusing to many clinicians in deciding which one to choose,” April W. Armstrong, MD, MPH, professor and chief of dermatology at the University of California, Los Angeles, said at the annual symposium of the California Society of Dermatology & Dermatologic Surgery.
One approach is to consider how the biologics compare in short- and long-term efficacy. “Several different meta-analyses of biologics have been conducted,” which include some head-to head studies, Dr. Armstrong said. “In terms of efficacy, [biologics] are similar at the population level,” she said.
In a meta-analysis of 71 randomized, controlled trials through July 2020, Dr. Armstrong and colleagues found that in the short-term, Psoriasis Area and Severity Index (PASI) 90 response rates at 10-16 weeks from baseline were highest for ixekizumab (72.9%), risankizumab (72.5%), and brodalumab (72%). These PASI 90 responses were significantly higher than among patients on guselkumab (65%), secukinumab (65%), infliximab (56.8%), certolizumab (400 mg: 49.6%; 200 mg: 42.2%), ustekinumab (90 mg: 47.9%; weight-based: 45.7%; 45 mg: 44.6%), adalimumab (43%), tildrakizumab (200 mg: 39.7%; 100 mg: 37.2%), etanercept (18.0%), apremilast (12.4%), and dimethyl fumarate (12.2%).
In a more recent meta-analysis, Dr. Armstrong and coauthors used area under the curve (AUC) analyses to compare the cumulative clinical benefits of biologics over 1 year. They found that the placebo-adjusted normalized maximum AUC for a PASI 100 response was greatest for ixekizumab (0.436), risankizumab (0.423), and brodalumab (0.378), followed by guselkumab (0.358), secukinumab (0.324), ustekinumab (0.201), adalimumab (0.183), and etanercept (0.087).
In Dr. Armstrong’s opinion, the tumor necrosis factor (TNF) inhibitors etanercept, infliximab, adalimumab, and certolizumab “have served their purpose for plaque psoriasis over time, but these days I would probably choose either an IL [interleukin]-17 inhibitor or an IL-23 inhibitor first,” she said. Still, TNF inhibitors “are certainly good for psoriatic arthritis, and certolizumab is appropriate for patients who are pregnant or breastfeeding,” she said. “Avoid them in patients with demyelinating disease and in those with hepatitis B. They are not preferred in patients with latent TB or advanced CHF.”
Dr. Armstrong said that there are robust efficacy data for the IL-17 inhibitors ixekizumab, secukinumab, and brodalumab in psoriasis and in the peripheral and axial forms of psoriatic arthritis (PsA). “Avoid using them in patients with a personal history of inflammatory bowel disease,” she advised.
Low rates of oral candidiasis have been reported in the literature, “but this has not been issue with our approved IL-17 inhibitors so far,” she said.
The IL-23 inhibitors guselkumab, risankizumab, tildrakizumab, and ustekinumab have robust data for psoriasis efficacy, she said, and three – guselkumab, risankizumab, and ustekinumab – are also approved for PsA. “These agents have the advantage of fewer injections, and the evidence [of efficacy] for IL-23 inhibitors continues to evolve, such as in patients with psoriatic arthritis involving the spine,” Dr. Armstrong said.
She also shared how she deals with patients who fail to respond to biologics. “Do you switch drugs, or do you dose escalate?” she asked. “In most cases, the strategy for dose escalation is to shorten the interval between the injections so the dosing is delivered more frequently.” In a case of primary failure, which Dr. Armstrong defined as a patient who has never responded optimally to a biologic, consider revisiting the diagnosis. “Maybe it’s cutaneous T-cell lymphoma or some other condition, because our current IL-17 and IL-23 medications work extremely well,” she said. “So, if you have a patient who is not responding at all, I would question the diagnosis and consider a biopsy.”
She generally waits about 6 months before switching a patient to another biologic, “to see if they’re one of the late bloomers who may catch up in efficacy,” she explained. “Switching the class of biologic is another consideration.”
If a patient had responded to the biologic for a long time and then lost response – known as secondary failure – Dr. Armstrong considers dose escalation or a switch to another agent within the same class “if it helps to address comorbidities such as PsA,” she said. “You can also try across-class switching.”
Dr. Armstrong disclosed ties with AbbVie, Arcutis, ASLAN, Beiersdorf, Boehringer Ingelheim, Bristol Myers Squibb, Dermira, Dermavant, EPI, Galderma, InCyte, Janssen, Leo, Lilly, Meiji, Modmed, Nimbus, Novartis, Ortho Dermatologics, Parexel, Pfizer, Regeneron, Sanofi, Suna, UCB, and Ventyx.

These PASI 90 responses were significantly higher than among patients on guselkumab (65%), secukinumab (65%), infliximab (56.8%), certolizumab (400 mg: 49.6%; 200 mg: 42.2%), ustekinumab (90 mg: 47.9%; weight-based: 45.7%; 45 mg: 44.6%), adalimumab (43%), tildrakizumab (200 mg: 39.7%; 100 mg: 37.2%), etanercept (18.0%), apremilast (12.4%), and dimethyl fumarate (12.2%).
In a more recent meta-analysis, Dr. Armstrong and coauthors used area under the curve (AUC) analyses to compare the cumulative clinical benefits of biologics over 1 year. They found that the placebo-adjusted normalized maximum AUC for a PASI 100 response was greatest for ixekizumab (0.436), risankizumab (0.423), and brodalumab (0.378), followed by guselkumab (0.358), secukinumab (0.324), ustekinumab (0.201), adalimumab (0.183), and etanercept (0.087).
In Dr. Armstrong’s opinion, the tumor necrosis factor (TNF) inhibitors etanercept, infliximab, adalimumab, and certolizumab “have served their purpose for plaque psoriasis over time, but these days I would probably choose either an IL [interleukin]-17 inhibitor or an IL-23 inhibitor first,” she said. Still, TNF inhibitors “are certainly good for psoriatic arthritis, and certolizumab is appropriate for patients who are pregnant or breastfeeding,” she said. “Avoid them in patients with demyelinating disease and in those with hepatitis B. They are not preferred in patients with latent TB or advanced CHF.”
Dr. Armstrong said that there are robust efficacy data for the IL-17 inhibitors ixekizumab, secukinumab, and brodalumab in psoriasis and in the peripheral and axial forms of psoriatic arthritis (PsA). “Avoid using them in patients with a personal history of inflammatory bowel disease,” she advised.
Low rates of oral candidiasis have been reported in the literature, “but this has not been issue with our approved IL-17 inhibitors so far,” she said.
The IL-23 inhibitors guselkumab, risankizumab, tildrakizumab, and ustekinumab have robust data for psoriasis efficacy, she said, and three – guselkumab, risankizumab, and ustekinumab – are also approved for PsA. “These agents have the advantage of fewer injections, and the evidence [of efficacy] for IL-23 inhibitors continues to evolve, such as in patients with psoriatic arthritis involving the spine,” Dr. Armstrong said.
She also shared how she deals with patients who fail to respond to biologics. “Do you switch drugs, or do you dose escalate?” she asked. “In most cases, the strategy for dose escalation is to shorten the interval between the injections so the dosing is delivered more frequently.” In a case of primary failure, which Dr. Armstrong defined as a patient who has never responded optimally to a biologic, consider revisiting the diagnosis. “Maybe it’s cutaneous T-cell lymphoma or some other condition, because our current IL-17 and IL-23 medications work extremely well,” she said. “So, if you have a patient who is not responding at all, I would question the diagnosis and consider a biopsy.”
She generally waits about 6 months before switching a patient to another biologic, “to see if they’re one of the late bloomers who may catch up in efficacy,” she explained. “Switching the class of biologic is another consideration.”
If a patient had responded to the biologic for a long time and then lost response – known as secondary failure – Dr. Armstrong considers dose escalation or a switch to another agent within the same class “if it helps to address comorbidities such as PsA,” she said. “You can also try across-class switching.”

Pelvic yoga, physical conditioning both improve urinary incontinence
PHILADELPHIA – Both a pelvic yoga program and a general physical conditioning program for incontinence led to improvements in women’s incontinence, according to a study presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).
“As clinicians, we’re usually focused on treatments that we ourselves can prescribe, perform, or administer. We’re not as good as recommending or supporting treatment or management strategies that don’t rely on costly or intensive visits with clinical specialists,” lead author Alison Huang, MD, MAS, a professor of medicine at the University of California, San Francisco, said in an interview.
“But our findings suggest that women who try pelvic yoga as a complementary management strategy for genitourinary conditions like urinary incontinence that often emerge in midlife are likely to experience substantial improvement in their genitourinary symptoms and function,” Dr. Huang said. “Some of these improvements may be shared with other forms of low-impact physical movement or exercise.”
The 240 participants from communities around three Northern California sites ranged in age from 45 to 90 years old, with an average age of 62, and all had at least daily urgency, stress, or mixed-type urinary incontinence. While most were White women, 40% identified as racial/ethnic minorities, including 14% Hispanic, 6% Black, 16% Asian American, and 4% multiracial.
Participants needed to be able to walk two blocks on level ground and get from a supine to a standing position on their own, but they should not have recently participated in any organized yoga or physical conditioning exercise classes. They also needed to forgo behavioral, invasive, or pharmacologic treatments for urinary incontinence for at least 3 months. The trial ran from 2019 to 2022, with most women completing the 3-month program virtually once the pandemic began.
The 121 women randomly assigned to the pelvic yoga program had twice-weekly group instruction by trained yoga instructors and once-weekly individual practice. The practice focused on 16 standard Hatha yoga poses in standing, seated, supine, and prone positions with an emphasis on precise alignment of their postures during each pose. Yoga props, such as blocks, straps, or bolsters, were available to minimize risk of injury and to accommodate women with less flexibility.
The 119 women randomly assigned to the physical conditioning group spent the same amount of group and individual class time on skeletal muscle stretching and strengthening exercises. These exercises focused on strengthening and stretching exercises for the upper and lower extremities in standing, sitting, or supine positions. The only props needed were exercise straps and handles and an exercise mat, and the program was designed to be safe and feasible for women across all ages.
Both groups received standard self-management pamphlets describing pelvic floor muscle exercises and recommendations on timed urination and urging suppression. After early dropouts from both arms, 107 women remained for analysis in the pelvic yoga group, and 113 women remained for analysis in the physical conditioning group.
Researchers assessed participants’ genitourinary quality of life at baseline and after 3 months using the Urogenital Distress Inventory-6 (UDI-6), Incontinence Impact Questionnaire (IIQ), and Patient Perception of Bladder Condition (PPBC). At baseline, the women’s average scores were 38.8 on the UDI-6, 101 on the IIQ, and 3.4 on the PPBC.
About one-third of the women in both groups attended all 24 group classes, and 57% of women in both groups attended 20-23 classes. In addition, 65% of the women in the pelvic yoga group and 73% of the women in the physical conditioning group completed all of the recommended additional hours of individual practice. Only 15% of pelvic yoga participants and 9% of physical conditioning participants completed less than 80% of the recommended individual practice hours. No differences in participation between the groups were statistically significant.
“Over 3 months, scores on all genitourinary quality of life measures improved by more than the minimum important difference thresholds in the pelvic yoga group,” the researchers reported, but only the UDI-6 score improved significantly – albeit still modestly – in the pelvic yoga group, compared with the physical conditioning group. Average scores improved 18.9 points in the pelvic yoga group and 13.1 points in the physical conditioning group (5.8-point difference; P = .02).
The scores on the IIQ improved an average 38.5 points in the pelvic yoga group and 31.4 points in the physical conditioning group (P = .48). PPBC scores improved 0.7 points in both groups.
“While yoga may offer benefits for genitourinary quality of life, it may not offer superior benefits compared to equivalent-time practice of other activities that improve general physical function,” Dr. Huang told attendees.
“The bottom line is that physical activity toward incontinence is a helpful technique,” Stephanie Faubion, MD, MBA, director for Mayo Clinic’s Center for Women’s Health and medical director for the Menopause Society, said in an interview regarding the findings. Urinary incontinence is under-recognized, Dr. Faubion said, “because women are embarrassed, so they don’t bring it up, so it doesn’t get managed.” But it’s a common problem, so clinicians need to ask patients about it, she said.
“We should realize that, in midlife and older age, genitourinary health is often connected to overall health,” Dr. Huang said in an interview. “We shouldn’t focus exclusively on treatments that are directed solely at the genital or lower urinary tract organs or tissues. We should consider the ways in which women’s urinary and sexual function are influenced by other aspects of their physical and cognitive health.”
The research was funded by the National Institutes of Health. Dr. Huang and Dr. Faubion had no disclosures.

Respiratory infections, asthma rise before type 2 diabetes
HAMBURG, GERMANY – , shows a longitudinal study looking at comorbidities both 25 years before and 25 years after a type 2 diabetes diagnosis.
About 40% of people had respiratory tract infections at the time of diagnosis with type 2 diabetes, compared with 4% who were not diagnosed. Likewise, ear, nose, and throat infections were present in 20% of people at type 2 diabetes diagnosis, compared with around 2% who were not diagnosed. A similar pattern was seen with asthma.
Taken together, the data suggest that subacute inflammation manifesting in asthma as well as the onset of asthma or an acute infection may be a precursor to a type 2 diabetes diagnosis.
“We have also found that in the years prior to diagnosis, there are associations with infections and inflammatory disorders to a much greater degree than in those people who do not get a diabetes diagnosis but who have very similar demographics,” Adrian Heald, MD, study lead and diabetes consultant from Salford (England) Royal Hospital, said in an interview.
Five years prior to diagnosis, respiratory tract infections were documented in around 23% of patients who were later diagnosed with type 2 diabetes versus 2.5% in those not diagnosed, and a similar pattern was seen for ear, nose, and throat infections and asthma. The findings suggest that patients reporting infections, in addition to other known risk factors for type 2 diabetes, might benefit from diabetes tests and early interventions, if needed.
“These novel insights offer a fascinating and fresh perspective on the onset and natural progression to type 2 diabetes and beyond, suggesting an early phase of inflammation-related disease activity long before any clinical diagnosis of type 2 diabetes is made.”
Dr. Heald points out that clinicians may intervene to stave off progression to a type 2 diabetes diagnosis in at risk patients. “At this point, an intervention could relate to lifestyle changes and involve highlighting to the patient that the morbidity they have already accumulated is suggestive of diabetes risk,” he said, adding that, “they may have dyslipidemia, hypertension, and most often excess weight so annual checks of their HbA1c, weight management, and blood pressure would need checking,” he explained.
Moderator Coen Stehouwer, MD, professor of internal medicine at Maastricht University, the Netherlands, commented, “Before clinical diagnosis of type 2 diabetes there is often a lengthy period of undiagnosed disease and before that, prediabetes, because glucose can be abnormal up to 10 years prior to clinical diagnosis.”
But he added that, “It’s not entirely clear whether the rise seen before clinical diagnosis in this study correlates with undiagnosed diabetes or prediabetes or even if it precedes type 2 diabetes – it might be because inflammation is a common origin for type 2 diabetes and various comorbidities. This might explain how they go together.”
Longitudinal study 25 years before and 25 years after type 2 diagnosis
Dr. Heald presented the findings at a session on inflammation in diabetes at the annual meeting of the European Association for the Study of Diabetes. The work was also published in Diabetes Therapy.
The researchers wanted to investigate the pattern of comorbidities in the years and decades prior to a diagnosis of type 2 diabetes as well as after: “With the database we used, called DARE [Diabetes Alliance for Research in England], we are able to explore phenomena longitudinally going right back to the beginning of their digital health records, looking at phenotypes over time.”
By mapping significant health issues in people who went on to develop type 2 diabetes alongside those that did not, Dr. Heald managed to develop a continuum spanning 25 years prior and 25 years after diagnosis of type 2 diabetes. The researchers also examined relationships between sociodemographic factors and longitudinal health outcomes of relevance to cardiac conditions and lower respiratory tract infections. His talk in Hamburg primarily addressed clinical phenotypes before the point of diagnosis.
Data were drawn from 1,932 people with (1,196) and without (736) type 2 diabetes. Participants in both groups were aged 66-67 years, 43%-46% were women, age at diagnosis was 50-52 years, and participants lived in Greater Manchester, United Kingdom.
In the years leading up to type 2 diagnosis, individuals consistently exhibited a considerable increase in several clinical phenotypes, reported Dr. Heald. Of note, he added, “immediately prior to type 2 diagnosis, there was a significantly greater proportion of hypertension at 35%, respiratory tract infection at 34%, heart disease at 17%, ear, nose, and throat infection at 19%, and asthma at 12%. And by comparison, the corresponding disease trajectory in matched controls was much less dramatic.”
“There is a huge difference in people who went on to receive a diagnosis of type 2 diabetes and those who did not, and not just what we’d expect – so hypertension for example or manifestations of renal disease, but importantly inflammatory disorders are more common,” he emphasized.
In addition, a larger signal for ischemic heart disease was seen just before type 2 diabetes diagnosis.
These data suggest that longitudinal clinical histories prior to a diagnosis of type 2 diabetes might offer new information, both genetic and nongenetic, about development of type 2 diabetes in relation to comorbidities.
After type 2 diabetes diagnosis, the proportion of people exhibiting coronary artery disease, hypertension, chronic kidney disease, retinopathy, and infections climbed rapidly before plateauing, reported Dr. Heald. “We also know that individuals with coronary artery disease are more highly represented in socially disadvantaged groups, and this is borne out in the data at 25 years prior and after type 2 diagnosis.”
Dr. Heald has received speaker fees or contributed to advisory boards from Lilly, AstraZeneca, Janssen, Bristol-Myers Squibb, Besins, Bayer, Sanofi, and Recordati. Research grants from Novo Nordisk, Pfizer, and Besins. Professor Stehouwer has declared no relevant conflicts.

Dr. Heald points out that clinicians may intervene to stave off progression to a type 2 diabetes diagnosis in at risk patients. “At this point, an intervention could relate to lifestyle changes and involve highlighting to the patient that the morbidity they have already accumulated is suggestive of diabetes risk,” he said, adding that, “they may have dyslipidemia, hypertension, and most often excess weight so annual checks of their HbA1c, weight management, and blood pressure would need checking,” he explained.
Moderator Coen Stehouwer, MD, professor of internal medicine at Maastricht University, the Netherlands, commented, “Before clinical diagnosis of type 2 diabetes there is often a lengthy period of undiagnosed disease and before that, prediabetes, because glucose can be abnormal up to 10 years prior to clinical diagnosis.”
But he added that, “It’s not entirely clear whether the rise seen before clinical diagnosis in this study correlates with undiagnosed diabetes or prediabetes or even if it precedes type 2 diabetes – it might be because inflammation is a common origin for type 2 diabetes and various comorbidities. This might explain how they go together.”
Longitudinal study 25 years before and 25 years after type 2 diagnosis
Dr. Heald presented the findings at a session on inflammation in diabetes at the annual meeting of the European Association for the Study of Diabetes. The work was also published in Diabetes Therapy.
The researchers wanted to investigate the pattern of comorbidities in the years and decades prior to a diagnosis of type 2 diabetes as well as after: “With the database we used, called DARE [Diabetes Alliance for Research in England], we are able to explore phenomena longitudinally going right back to the beginning of their digital health records, looking at phenotypes over time.”
By mapping significant health issues in people who went on to develop type 2 diabetes alongside those that did not, Dr. Heald managed to develop a continuum spanning 25 years prior and 25 years after diagnosis of type 2 diabetes. The researchers also examined relationships between sociodemographic factors and longitudinal health outcomes of relevance to cardiac conditions and lower respiratory tract infections. His talk in Hamburg primarily addressed clinical phenotypes before the point of diagnosis.
Data were drawn from 1,932 people with (1,196) and without (736) type 2 diabetes. Participants in both groups were aged 66-67 years, 43%-46% were women, age at diagnosis was 50-52 years, and participants lived in Greater Manchester, United Kingdom.
In the years leading up to type 2 diagnosis, individuals consistently exhibited a considerable increase in several clinical phenotypes, reported Dr. Heald. Of note, he added, “immediately prior to type 2 diagnosis, there was a significantly greater proportion of hypertension at 35%, respiratory tract infection at 34%, heart disease at 17%, ear, nose, and throat infection at 19%, and asthma at 12%. And by comparison, the corresponding disease trajectory in matched controls was much less dramatic.”
“There is a huge difference in people who went on to receive a diagnosis of type 2 diabetes and those who did not, and not just what we’d expect – so hypertension for example or manifestations of renal disease, but importantly inflammatory disorders are more common,” he emphasized.
In addition, a larger signal for ischemic heart disease was seen just before type 2 diabetes diagnosis.
These data suggest that longitudinal clinical histories prior to a diagnosis of type 2 diabetes might offer new information, both genetic and nongenetic, about development of type 2 diabetes in relation to comorbidities.
After type 2 diabetes diagnosis, the proportion of people exhibiting coronary artery disease, hypertension, chronic kidney disease, retinopathy, and infections climbed rapidly before plateauing, reported Dr. Heald. “We also know that individuals with coronary artery disease are more highly represented in socially disadvantaged groups, and this is borne out in the data at 25 years prior and after type 2 diagnosis.”
Dr. Heald has received speaker fees or contributed to advisory boards from Lilly, AstraZeneca, Janssen, Bristol-Myers Squibb, Besins, Bayer, Sanofi, and Recordati. Research grants from Novo Nordisk, Pfizer, and Besins. Professor Stehouwer has declared no relevant conflicts.

Thyroid cancer increase observed in transgender female veterans
WASHINGTON – Experts urge a cautious interpretation of these recent study results.
“In our clinic of about 50 transgender women, we noticed that we had two diagnosed cases of thyroid cancer in a year,” first author John Christensen, MD, of UC Davis Health, division of endocrinology, diabetes & metabolism, Sacramento, said in an interivew. He presented their findings at the annual meeting of the American Thyroid Association.
Comparatively, the thyroid cancer prevalence among cisgender male veterans is estimated at about 0.19%; the rate among all those assigned male at birth in the general population is 0.13%, whereas the rate among those assigned female at birth, which has historically been higher for all thyroid cancer subtypes, is 0.44%, according to U.S. cancer statistics for 2020 from the National Cancer Institute.
“About one-third of our [veteran] patients had been receiving estrogen for an average of over 3 years before diagnosis, which could suggest estrogen gender‐affirming hormone therapy [GAHT] may be a potentially important risk factor,” Dr. Christensen said.
Sustained use of external estrogen, especially in cisgender women undergoing fertility treatments, has been linked to an increased risk for thyroid cancer. This is because it can lead to an increase in estrogen receptors in cancerous cells. But experts caution that many other factors also come into play.
“There is definitely an implication that if you give extra estrogen to someone assigned female at birth, you may have an increased risk of thyroid cancer,” Dr. Christensen said. “So, it would stand to reason that even in those who are not assigned female at birth, there may be a risk from exogenous estrogen that may lead to an increased risk of thyroid cancer down the line.”
To investigate the issue in a larger population, Dr. Christensen and colleagues evaluated data from the comprehensive, nationwide Veterans Affairs Informatics and Computing Infrastructure database, including approximately 9 million veterans who had outpatient visits between December 2017 and January 2022.
Of the veterans, 9,988 were determined to likely be transgender women, based on either having an ICD-10 diagnosis code for gender dysphoria or being assigned male at birth and having received an estrogen or estradiol prescription.
Of those patients, 76 had an ICD-10 code indicating thyroid cancer and 34 had verification of the thyroid cancer on chart review, representing a prevalence of 0.34% among transgender female veterans.
The average age at thyroid cancer diagnosis among the veterans was 53.8 years, and 29.4% (10 of 34) of those patients had extrathyroidal disease at the time of their thyroid cancer diagnosis. The median body mass index, available for 26 patients, was 32, which is indicative of obesity.
In terms of the patients’ thyroid cancer subtypes, 22 were papillary cancer, 5 were a follicular variant of papillary cancer, 5 were both papillary and follicular cancer, 4 were follicular cancer, 3 were a Hürthle cell variant of follicular cancer, and one was unknown.
Among 11 (32.3%) of the 34 veterans receiving estrogen GAHT at diagnosis, treatment began an average of 3.38 years prior to diagnosis at variable doses and using various routes of administration.
About half of the patients had a history of smoking; however, Dr. Christensen noted that the role of smoking as being a risk factor in estrogenic cancers has been debated. Though most patients were obese, obesity is both very common and not well established in terms of its quantitative impact on the risk for cancer development.
With the small size of the thyroid cancer cohort and omissions in the medical record among the study’s important limitations, Dr. Christensen urged a cautious interpretation of the findings.
“We are certainly suspicious that GAHT may be associated with an increased risk of thyroid cancer, but I would characterize the trends in our data as being potentially suggestive or hypothesis generating – not conclusive,” he added. “I would hate for any transgender women reading this to stop taking GAHT without talking to their doctors first.”
Commenting on the issue, Maurice Garcia, MD, a clinical associate professor of urology and director of the transgender surgery and health program at Cedars-Sinai Medical Center, Los Angeles, said that any definitive evidence of an increase in cancer risk among transgender people is lacking.
“With an estimated 1.5 [million] to 1.6 million people in the U.S. who are transgender, with many of them receiving GAHT, we haven’t observed a bump or high incidence of any kind of cancer among these people so far,” he said.
“There’s certainly a high potential that hormone therapy, whether it’s feminizing or masculinizing hormone therapy, can affect an individual’s cancer risk,” he added. “But we don’t know of any [definitive evidence] yet of an increase, and, there’s also even the question of whether there could be an opposite effect.”
Regarding the thyroid cancer data, Dr. Garcia agreed that the preliminary nature of the study is a key limitation. “It’s hard to tell if these were comparable groups, or whether those in the transgender group came in with higher risk factors for thyroid cancer.
“Until more statistical analysis is done, I think all that can be said is that it’s speculative.”
Dr. Garcia, who coauthored a review on cancer screening for transgender individuals, underscored that, despite a lack of data suggesting that transgender patients need cancer screening any more than their matched cisgender counterparts, “the point is that we cannot forget to screen them at all.”
Dr. Christensen and Dr. Garcia had no disclosures to report.

Precision medicine takes individual approach to diabetes
HAMBURG, GERMANY –
“Diabetes recommendations often focus on what works well for the average person. However, because diabetes is an incredibly heterogeneous disease, few people are Mr. or Mrs. ‘average’ and one-size-fits-all approaches fail many people in need. Precision medicine seeks to address this major problem,” said Precision Medicine in Diabetes Initiative (PDMI) cochair Paul Franks, PhD, MPhil, head of the department of translational medicine at the Novo Nordisk Foundation in Denmark.
The report is the second from the joint American Diabetes Association/European Association for the Study of Diabetes PDMI, a consortium organized in 2018 with the aim of addressing “the untenable health and economic burdens of diabetes prevention and care.”
Based on findings from 15 systematic reviews and expert opinions, the new statement covers the key precision medicine pillars of prevention, diagnosis, treatment, and prognosis for each of four major recognized forms of diabetes: monogenic, gestational, type 1, and type 2. It addresses clinical translation of precision medicine research, including near-term actionable measures. Working groups were tasked with defining the key research questions that need to be addressed for precision diabetes medicine to be implemented into clinical practice by 2030.
Dr. Franks noted that “precision medicine seeks to improve diabetes prevention and care by combining data about a person’s health or disease state and response to medications. The aim is to tailor the advice given about diabetes prevention or treatment to the person in question, rather than having them make do with generic advice. Precision medicine very much focuses on treating the person and not the disease.”
A 90-minute symposium summarizing the report was presented at the annual meeting of the European Association for the Study of Diabetes. An executive summary was simultaneously published in the journal Nature Medicine. Four additional complementary papers, covering cardiometabolic disease precision medicine, diabetes heterogeneity, precision medicine of obesity, and precision cardiometabolic medicine in low- and middle-income countries, were published separately in The Lancet Diabetes & Endocrinology.
In a comment, Kamlesh Khunti, MD, professor of primary care diabetes and vascular medicine at the University of Leicester, England, called the new report “fantastic collaborative work.”
However, Dr. Khunti said, “I think at the moment we’re at the discovery stage of precision medicine. The clinical utility of that, we’ll have to see over the years.”
Dr. Khunti also pointed out: “A lot of the work done in precision medicine has been on specific diseases, like diabetes and cardiovascular disease. But, 30% of people don’t just have one disease, they have multiple long-term conditions. I think we need to start thinking about that now, rather than single conditions, because we want to look at drug targets that will hit multiple long-term conditions rather than one single condition.”
Currently, a dearth of data
Even just within diabetes, there is a dearth of quality data. In fact, Dr. Franks told this news organization, there has only been one precision medicine trial in diabetes, called TriMaster, comparing individual responses to three different second-line treatments for type 2 diabetes after metformin. “The problem with that trial is that the second-line medications it investigated aren’t widely prescribed now. The trial was designed back in 2014. It took a long time, then there was COVID, and by the time it was published too much time had elapsed and it was already out of date.”
Ideally, to make this effort current, Dr. Franks said, “is to get drug companies to implement these trials into their development pipelines. If you think about it, it’s far more efficient to implement precision medicine early in the drug development process than late, because when you do it late you end up having to do lots of comparisons of different possibilities. When you do it early you sort out those comparisons as part of the development process, so it really comes down to companies being willing to do that and regulators being willing to accept results from those trials. That’s another challenge, which is why we stress regulatory engagement as a key thing.”
In the future, he said, using the second-line type 2 diabetes drug as an example, when a person is diagnosed with type 2 diabetes they might automatically be given a companion diagnostic that’s more sophisticated and more precise than current ways of defining cardiovascular risk to better predict which individuals are more likely to experience a cardiovascular event.
This concept, referred to as “precision diagnostics,” is a “core driver of precision medicine,” Dr. Franks said. “If we can get a higher predictive accuracy on cardiovascular outcomes in people with diabetes, essentially treatment allocation is likely to be more precise too, because you’re not treating people you don’t need to treat and you’re not missing people you should have treated. I think that’s probably how it will work out.”
‘Studying diverse populations benefits everyone’
An important component emphasized in the report is the lack of “relevant, high-quality research in people of non-European ancestry, hindering the development and implementation of precision diabetes medicine in many of the most heavily burdened populations worldwide.”
That specific issue was addressed during the symposium by Shivani Misra, MBBS, PhD clinical senior lecturer in diabetes and endocrinology at Imperial College, London, and the lead author of the separate complementary paper on the topic.
Dr. Misra argued against the notion that precision medicine is only for wealthy countries, noting that diabetes and other noncommunicable diseases are becoming major health problems in low- and middle-income countries. “Resource-restricted settings may derive the greatest benefits from precision medicine,” she said. “Studying diverse populations benefits everyone.”
And worldwide, she noted, “the right drug for the right person will improve cost-effectiveness in the long-term.”
Dr. Franks is an employee of the Novo Nordisk Foundation, a “purely philanthropic enterprise-owning foundation” with a portfolio of 151 companies. He has received consultancy fees from Zoe Ltd., Eli Lilly, and Novo Nordisk, and research funding from multiple pharmaceutical companies. Dr. Khunti has acted as a consultant, speaker, or received grants for investigator-initiated studies from AstraZeneca, Novartis, Novo Nordisk, Sanofi-Aventis, Lilly and Merck Sharp & Dohme, Boehringer Ingelheim, Bayer, Berlin-Chemie/Menarini Group, Janssen, and Napp. Dr. Misra has received speaker fees from Sanofi and ABCD and an investigator-initiated research grant from Dexcom, and is a trustee for the Diabetes Research and Wellness Foundation.

However, Dr. Khunti said, “I think at the moment we’re at the discovery stage of precision medicine. The clinical utility of that, we’ll have to see over the years.”
Dr. Khunti also pointed out: “A lot of the work done in precision medicine has been on specific diseases, like diabetes and cardiovascular disease. But, 30% of people don’t just have one disease, they have multiple long-term conditions. I think we need to start thinking about that now, rather than single conditions, because we want to look at drug targets that will hit multiple long-term conditions rather than one single condition.”
Currently, a dearth of data
Even just within diabetes, there is a dearth of quality data. In fact, Dr. Franks told this news organization, there has only been one precision medicine trial in diabetes, called TriMaster, comparing individual responses to three different second-line treatments for type 2 diabetes after metformin. “The problem with that trial is that the second-line medications it investigated aren’t widely prescribed now. The trial was designed back in 2014. It took a long time, then there was COVID, and by the time it was published too much time had elapsed and it was already out of date.”
Ideally, to make this effort current, Dr. Franks said, “is to get drug companies to implement these trials into their development pipelines. If you think about it, it’s far more efficient to implement precision medicine early in the drug development process than late, because when you do it late you end up having to do lots of comparisons of different possibilities. When you do it early you sort out those comparisons as part of the development process, so it really comes down to companies being willing to do that and regulators being willing to accept results from those trials. That’s another challenge, which is why we stress regulatory engagement as a key thing.”
In the future, he said, using the second-line type 2 diabetes drug as an example, when a person is diagnosed with type 2 diabetes they might automatically be given a companion diagnostic that’s more sophisticated and more precise than current ways of defining cardiovascular risk to better predict which individuals are more likely to experience a cardiovascular event.
This concept, referred to as “precision diagnostics,” is a “core driver of precision medicine,” Dr. Franks said. “If we can get a higher predictive accuracy on cardiovascular outcomes in people with diabetes, essentially treatment allocation is likely to be more precise too, because you’re not treating people you don’t need to treat and you’re not missing people you should have treated. I think that’s probably how it will work out.”
‘Studying diverse populations benefits everyone’
An important component emphasized in the report is the lack of “relevant, high-quality research in people of non-European ancestry, hindering the development and implementation of precision diabetes medicine in many of the most heavily burdened populations worldwide.”
That specific issue was addressed during the symposium by Shivani Misra, MBBS, PhD clinical senior lecturer in diabetes and endocrinology at Imperial College, London, and the lead author of the separate complementary paper on the topic.
Dr. Misra argued against the notion that precision medicine is only for wealthy countries, noting that diabetes and other noncommunicable diseases are becoming major health problems in low- and middle-income countries. “Resource-restricted settings may derive the greatest benefits from precision medicine,” she said. “Studying diverse populations benefits everyone.”
And worldwide, she noted, “the right drug for the right person will improve cost-effectiveness in the long-term.”
Dr. Franks is an employee of the Novo Nordisk Foundation, a “purely philanthropic enterprise-owning foundation” with a portfolio of 151 companies. He has received consultancy fees from Zoe Ltd., Eli Lilly, and Novo Nordisk, and research funding from multiple pharmaceutical companies. Dr. Khunti has acted as a consultant, speaker, or received grants for investigator-initiated studies from AstraZeneca, Novartis, Novo Nordisk, Sanofi-Aventis, Lilly and Merck Sharp & Dohme, Boehringer Ingelheim, Bayer, Berlin-Chemie/Menarini Group, Janssen, and Napp. Dr. Misra has received speaker fees from Sanofi and ABCD and an investigator-initiated research grant from Dexcom, and is a trustee for the Diabetes Research and Wellness Foundation.

Higher RT doses can boost lifespan, reduce risk of death in LS-SCLC patients
SAN DIEGO – , according to a new multicenter, open-label, randomized phase III trial.
Among 224 patients in China, aged 18-70, those randomly assigned to receive volumetric-modulated arc radiotherapy of high-dose, hypofractionated thoracic radiotherapy of 54 Gy in 30 fractions had a much higher median overall survival (62.4 months) than those who received the standard dose of 45 Gy in 30 fractions (43.1 months, P = .001), reported Jiayi Yu, PhD, of Beijing University Cancer Hospital and Institute and colleagues at the annual meeting of the American Society for Radiation Oncology.
Median progression-free survival was also higher in the 54 Gy group (30.5 months vs. 16.7 months in the 45 Gy group, P = .044).
Kristin Higgins, MD, of Winship Cancer Institute of Emory University, Atlanta, provided perspective at the ASTRO session following Dr. Yu’s presentation. She noted that the study population is quite different than that of LS-SCLC patients in the United States, where patients are often older and more likely to have a history of smoking.
“We need more technical details to understand how to deliver this regimen in clinical practice, and it may not be applicable for all patients,” she said. Still, she added that “a key takeaway here is that optimizing the radiotherapy component of treatment is very important.”
Both groups received chemotherapy. “Higher-dose thoracic radiation therapy concurrently with chemotherapy is an alternative therapeutic option,” Dr. Yu said at an ASTRO presentation.
As Dr. Yu noted, twice-daily thoracic radiotherapy of 45 Gy in 30 fractions and concurrent chemotherapy has been the standard treatment for LS-SCLC for the last 20 years. Trials failed to show benefits for once-daily 66-Gy (33 fractions) or 70-Gy treatment (35 fractions), but a phase 2 trial published in 2023 did indicate that twice-daily treatment of 60 Gy (40 fractions) improved survival without boosting side effects.
For the new study, researchers tracked 224 patients from 2017 to 2021 who were previously untreated or had received specific chemotherapy treatments and had ECOG performance status scores of 0 or 1; 108 patients were randomly assigned to the 54-Gy arm and 116 to the 45-Gy arm. All were recruited at 16 public hospitals in China.
The median age in the two groups were 60 in the 54-Gy arm and 62 in the 45-Gy arm; the percentages of women were similar (45.4% and 45.7%, respectively). Most were current or former smokers (62.0% and 61.2%, respectively).
The researchers closed the trial in April 2021 because of the survival benefit in the 54-Gy arm, and patients were tracked through January 2023 for a median 45 months.
Nearly three-quarters of patients in the 54-Gy arm survived to 2 years (77.7%) vs. 53.4% in the 45-Gy arm, a 41% reduction in risk of death. Adverse events were similar between the groups, with 1 reported treatment-related death (myocardial infarction), in the 54-Gy group.
In an interview, Kenneth Rosenzweig, MD, chairman of the department of radiation oncology at Icahn School of Medicine at Mount Sinai, New York, praised the study. It’s “no surprise” that higher radiation doses are well-tolerated since “our ability to shield normal tissue has improved” over the years, said Dr. Rosenzweig, who served as a moderator of the ASTRO session where the research was presented.
However, he cautioned that hypofractionation is still “intense” and may not be appropriate for certain patients. And he added that some clinics may not be set up to provide twice-daily treatments.
Information about study funding was not provided. The study authors have no disclosures. Dr. Higgins discloses relationships with AstraZeneca and Regeneron (advisory board), Jazz (funded research), and Janssen and Picture Health (consulting). Dr. Rosenzweig has no disclosures.

CT simulation not needed in palliative radiotherapy planning
, according to a results from a randomized trial presented at the annual meeting of the American Society for Radiation Oncology.
The aim of this same-day CT scan, called a CT simulation scan, is to optimize radiation targeting by mimicking the conditions under which radiation is delivered using the latest information on the size and location of lesions.
But investigators reported that skipping the CT simulation scan saves patients hours in the clinic, allows patients to experience pain relief faster, and saves radiation oncologists time without compromising dosimetric coverage of cancerous lesions.
“This is huge in a symptomatic patient population,” said Melissa O’Neil, an advanced practice radiation therapist at the London, Ont., Health Sciences Centre and the lead investigator on the trial, dubbed DART (Diagnostic CT-Enabled Radiation Therapy).
“Diagnostic CT-based radiation planning substantially reduces time in the [treatment] center without a detriment in plan deliverability or quality,” Ms. O’Neil said.
In addition, patients are exposed to less radiation, and staff doesn’t have to spend as much time tending to symptomatic patients before treatment. Omitting this scan “should be considered for patients with a recent diagnostic CT scan who are undergoing simple palliative radiation,” Ms. O’Neil said.
CT simulation scans are standard of care in cases involving palliative radiation, but they create bottlenecks in the workflow. When a CT simulation is performed on the day of treatment, patients must wait hours as the results are translated into a treatment plan.
In the DART analysis, 33 patients with 42 treatment sites were randomly assigned to CT simulation planning or diagnostic CT planning.
Patients received up to 30 Gy in up to 10 fractions for bone or soft tissue metastases or primary tumor targets in the thorax, abdomen, pelvis, or proximal limbs. Single-fraction treatments were most common.
Three-quarters of the patients were men (median age, 72 years). Lung cancer was the most common type of primary tumor, followed by prostate and breast cancer.
The eight participants for whom the CT simulation approach was used waited 3-4 hours for treatment planning and overall spent a median of 4.8 hours in the cancer center on their day of treatment.
The 25 patients for whom diagnostic CT planning was used spent a median of 0.4 hours, or about 24 minutes, in the center on their day of treatment because radiation plans were completed before they arrived. The median time between their diagnostic CTs and radiation treatment was 13 days (range, 8-22 days).
Ms. O’Neil and her team found that if the original diagnostic CT was performed within 28 days, lesion anatomy would not have changed enough to warrant a new scan.
On the day of treatment, the study team used surface-guided radiation therapy techniques to ensure patients in the diagnostic CT planning group were positioned within 3 mm of where they were during their diagnostic scans, an essential step to ensure that radiation is delivered to the correct location. Ms. O’Neil noted that other investigators have used anatomic landmarks, a simpler approach, to achieve these results.
Overall, radiation oncologists rated radiation dose distribution as “acceptable” in about 80% of cases in both arms of DART and “acceptable with minor deviation” in the remaining 20% of cases.
Every radiation oncologist and medical physicists in the trial gave the workflow with diagnostic CT planning a 5 out of 5 rating for acceptability, and 90% of patients in this group rated the amount of time they spent for treatment as “acceptable.”
In contrast, only half of patients in the simulation arm said the amount of time spent was acceptable.
These findings align with several previous studies that support the diagnostic approach.
Jacob Scott, MD, a radiation oncologist at the Cleveland Clinic, said, “The comparable results using a recent diagnostic CT in place of a CT simulation for palliative radiation is an exciting step forward in radiation oncology. We may soon be in a world where we no longer need simulations.”
Dr. Scott also noted that combining diagnostic scans with cone beam or surface-guided positioning in lieu of CT simulations could further save “the health system and patients time and money.”
No external funding for the study was reported. The investigators, Ms. O’Neil, and Dr. Scott have disclosed no relevant financial relationships. One investigator reported receiving honoraria from Knight Therapeutics, AbbVie, Tersera, and Eisai and owns stock in Myovant.
