The combination of nivolumab and vidutolimod led to a high rate of pathologic complete response and pathologic major response in a phase 2 trial of patients with stage 3 resectable melanoma. The result led researchers to call for a future study comparing the regimen against a suitable control group.

“We were very excited to see the ability of intratumoral vidutolimod to augment T-cell infiltrate. (Pathologic) response was associated with a dense infiltrate of CD8 T cells. We were also able to demonstrate for what I think may be the first time, that intratumoral CpG resulted in clear evidence of CD303+ plasmacytoid dendritic cells [pDCs],” said Diwakar Davar, MD, assistant professor of medicine at the University of Pittsburgh, during a presentation of the results at the annual meeting of the Society for Immunotherapy of Cancer. He noted that pDCs represent a very rare cell population, less than 0.4% of circulating peripheral blood mononuclear cells, and tend to be found in lymph nodes.

The current standard of care for stage 3 melanoma is up-front surgery followed by adjuvant therapy – anti–PD-1 therapy for patients with wild-type or BRAF-mutant cancers, and targeted therapy with BRAF/MEK inhibitors in patients with BRAF mutations. However, preclinical studies suggest that neoadjuvant immunotherapy could lead to a stronger antitumor T-cell response than adjuvant immunotherapy.

Vidutolimod targets the toll-like receptor 9 (TLR-9) endosomal receptor found in B cells and pDC cells. The formulation is a virus-like particle (VLP) that contains unmethylated cytosine guanine–rich oligonucleotides (CpG ODN). Bacterial and viral genomes tend to be enriched in CpG ODN, and this acts as a TLR-9 agonist. TLR-9 activation in turn triggers an interferon response, and this may help overcome PD-1 blockade resistance in metastatic melanoma.

The researchers conducted a nonrandomized, open-label trial that included 30 patients with stage 3 melanoma (14 women; median age, 61 years). Patients received neoadjuvant nivolumab and vidutolimod for 8 weeks, then were evaluated for surgery. Patients continued both drugs in the adjuvant setting for 48 weeks. 47% experienced complete pathologic response, 10% a major pathologic response, and 10% a partial pathologic response.

Analysis of resected samples revealed clear evidence of an immune response, Dr. Davar said during a press conference held in advance of the meeting. “Pathologic response was associated with compelling evidence of immune activation both peripherally and within the tumor, with clear evidence of pDC infiltrate and pDC activation – something that has not previously been seen in human specimens.”

The study regimen appeared safe, with no dose-limiting toxicities or grade 4 or 5 adverse events. He noted that the regimen is now being tested in the phase 2 ECOG-ACRIN trial.

The results are “very exciting,” said Pamela Ohashi, PhD, who commented on the study during the press conference. The virus-like nature of vidutolimod may be an important element of the therapy. “I think scientifically we would have predicted that the VLP carrying the CPG would be very good at activating the CD8 cells, which in fact is what you’re seeing. So I think it’s very exciting and has lots of potential for future combinations,” said Dr. Ohashi, who is director of the tumor immunotherapy program at the Princess Margaret Cancer Centre, Toronto.

The U.S. Food and Drug Administration has approved etranacogene dezaparvovec (Hemgenix), the first gene therapy option for adults with hemophilia B who currently use factor IX prophylaxis therapy, have current or historical life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.*

“Gene therapy for hemophilia has been on the horizon for more than 2 decades. Despite advancements in the treatment of hemophilia, the prevention and treatment of bleeding episodes can adversely impact individuals’ quality of life,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research. “Today’s approval provides a new treatment option for patients with hemophilia B and represents important progress in the development of innovative therapies for those experiencing a high burden of disease associated with this form of hemophilia.”

Hemophilia B is caused by a deficiency in clotting factor IX attributable to a faulty gene. The newly approved IV infusion delivers a functional gene to liver cells via an adeno-associated virus that instructs them to make the clotting factor. The genetic instructions remain in the cell but aren’t incorporated into the patient’s own DNA, according to a press release from maker CSL Behring.

The gene therapy will cost $3.5 million, making it the most expensive treatment to date -- more than Bluebird's recently approved gene therapies. A recent analysis from the Institute for Clinical and Economic Review said charging $2.93-$2.96 million would be justified because etranacogene dezaparvovec would offset the need for ongoing factor IX replacement, which can top $20 million over a lifetime.

Approval was based on the single-arm, open-label HOPE-B trial in 54 men who relied on factor IX replacement therapy; most patients with hemophilia B are male.

Over the 18 months after infusion, their adjusted annualized bleeding rate fell 64% compared with baseline (P = .0002), and factor IX–treated bleeds fell 77% (P < .0001); 98% of subjects treated with a full dose of etranacogene dezaparvovec discontinued factor IX prophylaxis.

Durability of the effect remains a concern, but data have been reassuring, with subjects having a mean factor IX activity of 39 IU/dL at 6 months – 39% of normal – and 36.9 IU/dL at 18 months, about 37% of normal. There’s been no sign so far of patients developing inhibitors against the infusion.

Adverse events were common but largely mild and included headache and influenza-like illness, both in 13% of subjects. Nine patients needed steroids for liver enzyme elevations.

The trial was temporarily halted due to a case of liver cancer, but it was ultimately deemed not to be related to treatment, based on molecular tumor characterization and vector integration analysis. A death in the trial was also not considered treatment related.

Other gene therapies are in the pipeline for hemophilia, including valoctocogene roxaparvovec (Roctavian, BioMarin) for hemophilia A. FDA’s approval decision is expected in March 2023.

A drug used in the treatment of relapsed/refractory multiple myeloma (RRMM) is in the process of being pulled off the U.S. market by its manufacturer.

The drug is belantamab mafodotin-blmf (Blenrep), an antibody drug conjugate that targets B-cell maturation antigen (BCMA).

The manufacturer, GSK, announced that it has started the process of withdrawing this drug from the market at the request of the U.S. Food and Drug Administration (FDA).

This request follows disappointing results from a large confirmatory trial, known as DREAMM-3, in which the drug failed to meet the primary endpoint of showing an improvement in progression-free survival (PFS).

The company was obliged to carry out this confirmatory trial after the FDA granted an accelerated approval for the drug in August 2020.

The accelerated approval was based on response data, and it was dependent on later trials’ confirming a clinical benefit. In this case, those trials did not confirm a clinical benefit.

“We respect the Agency’s approach to the accelerated approval regulations and associated process,” commented the GSK Chief Medical Officer Sabine Luik.

The company will continue to “work with the U.S. FDA on a path forward for this important treatment option for patients with multiple myeloma.”

Further clinical trials in the DREAMM program are still underway. Results from the DREAMM-7 and DREAMM-8 trials are expected in early 2023.

The company had high hopes for the drug when it was launched. At that time, belanatamab mafodotin-blmf was the only drug on the market that targeted BCMA, and so it was the first drug in its class.

However, it is no longer unique. In the 2 years that it has been available, several other products that target BCMA have been launched for use in the treatment of multiple myeloma. These include the two chimeric antigen receptor T-cell products, idecabtagene vicleucel (Abecma) and ciltacabtagene autoleucel (Carvykti), as well as the bispecific antibody teclistamab (Tecvayli).
 

For relapsed/refractory disease

Belantamab mafodotin-blmf was approved for use in patients with RRMM who had already undergone treatment with one of the three major classes of drugs, namely, an immunomodulatory agent, a proteasome inhibitor, and a CD-38 monoclonal antibody.

Patients who are currently taking the drug and would like to continue doing so will have the option to enroll in a compassionate use program to retain their access to treatment, the company said.

“GSK continues to believe, based on the totality of data available from the DREAMM (DRiving Excellence in Approaches to Multiple Myeloma) development program, that the benefit-risk profile of belantamab mafodotin remains favorable in this hard-to-treat RRMM patient population. Patients responding to belantamab mafodotin experienced durable clinical benefit, and safety remains consistent with the known safety profile,” the company said.
 

Details of DREAMM-3 results

DREAMM-3 was a phase 3 trial that compared single-agent belantamab mafodotin to pomalidomide (Pomalyst) in combination with low-dose dexamethasone (PomDex) for patients with RRMM.

The results for the primary endpoint of PFS did not reach statistical significance: median PFS was 11.2 vs. 7 months with PomDex (hazard ratio, 1.03; 95% confidence interval, 0.72-1.47).

At the time of the primary analysis, the overall survival (OS) data had only achieved 37.5% overall maturity. The median OS was 21.2 vs. 21.1 months with PomDex (HR, 1.14; 95% CI, 0.77-1.68).

Numerous species of fungi exist in cancer cells and differ by tumor type, according to findings from a large study of multiple sample types across 35 different cancers.

The investigators characterized the cancer mycobiome within 17,401 tissue, blood, and plasma samples from four international cohorts, revealing new information about fungi distribution, association with immune cells, and potential prognostic value.

Fungi were detected in all cancer types studied and were often intracellular, reported Lian Narunsky-Haziza, PhD, of Weizmann Institute of Science, Rehovot, Israel, and colleagues.

Additionally, multiple fungal-bacterial-immune ecologies were detected across tumors, and intratumoral fungi stratified clinical outcomes, including immunotherapy response, they noted. Also, cell-free fungal DNA diagnosed healthy and cancer patients in early-stage disease.

The findings, published online in the journal Cell, have potential implications for cancer detection, diagnosis, and treatment, the researchers suggested.

The existence of fungi in most human cancers “is both a surprise and to be expected,” study coauthor Rob Knight, PhD, a professor at the University of California, San Diego, stated in a press release. “It is surprising because we don’t know how fungi could get into tumors throughout the body. But it is also expected, because it fits the pattern of healthy microbiomes throughout the body, including the gut, mouth, and skin, where bacteria and fungi interact as part of a complex community.”

Exploration of the associations between cancer and microbes are nothing new, but cancer-associated fungi have rarely been examined, the authors noted.

The findings from this pan-cancer analysis, which suggested “prognostic and diagnostic capacities of the tissue and plasma mycobiomes, even in stage I cancers,” complement current “understanding of the interaction between cancer cells and the bacteria that exist in tumors alongside fungi, bacteria that have been shown to affect cancer growth, metastasis, and response to therapy,” they explained.

Of note, the study revealed multiple correlations between the presence of specific fungi in tumors and conditions related to treatment. For example, patients with breast cancer whose tumors contained Malassezia globosa – a fungus found naturally on the skin – had a much lower survival rate than those whose tumors did not contain the fungus. Furthermore, specific fungi were more prevalent in breast tumors from older vs. younger patients, in lung tumors of smokers vs. nonsmokers, and in melanoma tumors that responded to immunotherapy vs. those that did not respond.

These findings suggest that fungal activity is “a new and emerging hallmark of cancer,” stated study coleader Ravid Straussman, PhD, of the Weizmann molecular cell biology department. “These findings should drive us to better explore the potential effects of tumor fungi and to re-examine almost everything we know about cancer through a ‘microbiome lens.’ ”

Unique relationships observed between fungi and bacteria – for example, tumors that contain Aspergillus fungi tended to have specific bacteria in them, whereas tumors that contain Malassezia fungi tended to have other bacteria in them – may have implications for treatment, as they correlated with both tumor immunity and patient survival, according to the authors.

“This study sheds new light on the complex biological environment within tumors, and future research will reveal how fungi affect cancerous growth,” said coauthor Yitzhak Pilpel, PhD, a principal investigator at the Weizmann molecular genetics department. “The fact that fungi can be found not only in cancer cells but also in immune cells implies that, in the future, we’ll probably find that fungi have some effect not only on the cancer cells but also on immune cells and their activity.”

A further finding related to the presence of fungal and bacterial DNA in human blood further suggests that measuring microbial DNA in the blood could lead to early detection of cancer, the authors noted.

Numerous species of fungi exist in cancer cells and differ by tumor type, according to findings from a large study of multiple sample types across 35 different cancers.

The investigators characterized the cancer mycobiome within 17,401 tissue, blood, and plasma samples from four international cohorts, revealing new information about fungi distribution, association with immune cells, and potential prognostic value.

Fungi were detected in all cancer types studied and were often intracellular, reported Lian Narunsky-Haziza, PhD, of Weizmann Institute of Science, Rehovot, Israel, and colleagues.

Additionally, multiple fungal-bacterial-immune ecologies were detected across tumors, and intratumoral fungi stratified clinical outcomes, including immunotherapy response, they noted. Also, cell-free fungal DNA diagnosed healthy and cancer patients in early-stage disease.

The findings, published online in the journal Cell, have potential implications for cancer detection, diagnosis, and treatment, the researchers suggested.

The existence of fungi in most human cancers “is both a surprise and to be expected,” study coauthor Rob Knight, PhD, a professor at the University of California, San Diego, stated in a press release. “It is surprising because we don’t know how fungi could get into tumors throughout the body. But it is also expected, because it fits the pattern of healthy microbiomes throughout the body, including the gut, mouth, and skin, where bacteria and fungi interact as part of a complex community.”

Exploration of the associations between cancer and microbes are nothing new, but cancer-associated fungi have rarely been examined, the authors noted.

The findings from this pan-cancer analysis, which suggested “prognostic and diagnostic capacities of the tissue and plasma mycobiomes, even in stage I cancers,” complement current “understanding of the interaction between cancer cells and the bacteria that exist in tumors alongside fungi, bacteria that have been shown to affect cancer growth, metastasis, and response to therapy,” they explained.

Of note, the study revealed multiple correlations between the presence of specific fungi in tumors and conditions related to treatment. For example, patients with breast cancer whose tumors contained Malassezia globosa – a fungus found naturally on the skin – had a much lower survival rate than those whose tumors did not contain the fungus. Furthermore, specific fungi were more prevalent in breast tumors from older vs. younger patients, in lung tumors of smokers vs. nonsmokers, and in melanoma tumors that responded to immunotherapy vs. those that did not respond.

These findings suggest that fungal activity is “a new and emerging hallmark of cancer,” stated study coleader Ravid Straussman, PhD, of the Weizmann molecular cell biology department. “These findings should drive us to better explore the potential effects of tumor fungi and to re-examine almost everything we know about cancer through a ‘microbiome lens.’ ”

Unique relationships observed between fungi and bacteria – for example, tumors that contain Aspergillus fungi tended to have specific bacteria in them, whereas tumors that contain Malassezia fungi tended to have other bacteria in them – may have implications for treatment, as they correlated with both tumor immunity and patient survival, according to the authors.

As many as 40% of patients with cancer develop hiccups – often unbeknownst to their oncologists. But even if recognized, hiccups may not be treated effectively, according to a national survey of cancer care clinicians.

When poorly controlled, persistent hiccups can affect a patient’s quality of life, with 40% of survey respondents considering chronic hiccups “much more” or “somewhat more” severe than nausea and vomiting.

Overall, the findings indicate that patients with cancer who develop persistent hiccups are “truly suffering,” the authors wrote.

The survey results were published online recently in the American Journal of Hospice and Palliative Medicine.

Hiccups may simply be a nuisance for most, but these spasms can become problematic for patients with cancer, leading to sleep deprivation, fatigue, aspiration pneumonia, compromised food intake, weight loss, pain, and even death.

Hiccups can develop when the nerve that controls the diaphragm becomes irritated, which can be triggered by certain chemotherapy drugs.

Yet few studies have focused on hiccups in patients with cancer and none, until now, has sought the perspectives of cancer care clinicians.

Aminah Jatoi, MD, medical oncologist with the Mayo Clinic in Rochester, Minn., and two Mayo colleagues developed a survey, alongside MeterHealth, which this news organization distributed to clinicians with an interest in cancer care.

The survey gauged clinicians’ awareness or lack of awareness about clinically significant hiccups as well as treatments for hiccups and whether they consider hiccups an unmet palliative need.

A total of 684 clinicians completed two eligibility screening questions, which required them to have cared for more than 10 patients with cancer in the past 6 months with clinically significant hiccups (defined as hiccups that lasted more than 48 hours or occurred from cancer or cancer care).

Among 113 eligible health care professionals, 90 completed the survey: 42 physicians, 29 nurses, 15 nurse practitioners, and 4 physician assistants.

The survey revealed three key issues.

The first is that hiccups appear to be an underrecognized issue.

Among health care professionals who answered the eligibility screening questions, fewer than 20% reported caring for more than 10 patients with cancer in the past 6 months who had persistent hiccups. Most of these clinicians reported caring for more than 1,000 patients per year.

Given that 15%-40% of patients with cancer report hiccups, this finding suggests that hiccups are not widely recognized by health care professionals.

Second: The survey data showed that hiccups often increase patients’ anxiety, fatigue, and sleep problems and can decrease productivity at work or school.

In fact, when comparing hiccups to nausea and vomiting – sometimes described as one of the most severe side effects of cancer care – 40% of respondents rated hiccups as “much more” or “somewhat more” severe than nausea and vomiting for their patients and 38% rated the severity of the two issues as “about the same.”

Finally, even when hiccups are recognized and treated, about 20% of respondents said that current therapies are not very effective, and more treatment options are needed.

Among the survey respondents, the most frequently prescribed medications for chronic hiccups were the antipsychotic chlorpromazine, the muscle relaxant baclofen (Lioresal), the antiemetic metoclopramide (Metozolv ODT, Reglan), and the anticonvulsants gabapentin (Neurontin) and carbamazepine (Tegretol).

Survey respondents who provided comments about current treatments for hiccups highlighted a range of challenges. One respondent said, “When current therapies do not work, it can be very demoralizing to our patients.”  Another said, “I feel like it is a gamble whether treatment for hiccups will work or not.”

Still another felt that while current treatments work “quite well to halt hiccups,” they come with side effects which can be “quite severe.”

These results “clearly point to the unmet needs of hiccups in patients with cancer and should prompt more research aimed at generating more palliative options,” the authors said.

This research had no commercial funding. MeterHealth reviewed the manuscript and provided input on the accuracy of methods and results. Dr. Jatoi reports serving on an advisory board for MeterHealth (honoraria to institution).

An epidemiological analysis using genetic data shows that having babies protects women from endometrial cancer.

Compared with having no children, the risk reduction for endometrial cancer was 21% with having one child, 38% with having two, and 51% with having three, Gunn-Helen Moen, MSc, PhD, a research fellow at the University of Queensland Institute for Molecular Bioscience in St. Lucia, Australia, and the senior author of the study, said in an email.

In the United States, the prevalence of endometrial cancer is 25.7 per 100,000 women per year, with a lifetime risk of 2.8%.

Multiple observational studies have linked giving birth to risk of endometrial cancer. For the new study, Dr. Moen and her team assessed various risk factors related to ovulation and reproductive function using Mendelian randomization, an epidemiological technique that deploys genetic variants to detect cause-and-effect relationships between potentially modifiable risk factors and health outcomes in observational data.

The researcher published their findings in BMC Medicine.
 

Leverage genetic data

The study used detailed genetic and health data from the UK Biobank, a databank with more than half a million participants. Genetic variants related to some of the risk factors were used to assess whether the variants make people more likely to develop endometrial cancer.

Genomewide significant single-nucleotide polymorphisms (SNPs) related to number of live births, age at menopause and menarche, and body mass index (BMI) had been identified in previous studies, the researchers reported. They conducted genomewide association analyses of the databank to identify SNPs associated with years ovulating, years using the contraceptive pill, and age at last live birth.

The MR analysis showed a potential causal effect for the number of live births (inverse variance–weighted odds ratio, 0.537) and number of years ovulating (IVW OR, 1.051), in addition to known risk factors of BMI, age at menarche, and age at menopause.

A further multivariable MR analysis showed that number of births had a negative causal effect on endometrial cancer risk (OR, 0.783), independent of the causal effect of known risk factors such as BMI, age at menarche and age at menopause.

Reported limitations included being unable to perform MR analyses on some factors, such as oral contraceptive use, because of a lack of valid genetic instruments. The researchers could not perform an age adjustment at diagnosis because of a lack of data.

In addition, the genetic data came exclusively from White women of European ancestry.
 

‘A personal choice’

Other investigators have hypothesized that the protective effect of childbirth may be caused by shedding of malignant and premalignant endometrial cells during and after childbirth and exposure to high levels of progesterone in late stages of pregnancy, the research team noted.

Dr. Moen said, based on the results, physicians might consider number of childbirths in assessing a patient’s risk of endometrial cancer.

However, Britton Trabert, MSPH, MS, PhD, an epidemiologist and assistant professor of obstetrics and gynecology at the University of Utah, Salt Lake City, said it’s unlikely the findings will affect clinical practice given that they “largely replicate well-characterized endometrial cancer risk associations.”

“Pregnancy and childbirth are a personal choice and is not largely regarded as a modifiable factor for cancer prevention,” said Dr. Trabert, who was not involved in the study.

The study’s investigators reported funding from the governments of Australia, Norway and the United Kingdom and the British Heart Foundation. No financial conflicts of interest were reported. Dr. Trabert reported no relevant financial interests.

Idiopathic thrombocytopenic purpura (ITP) is an immune-mediated acquired condition affecting both adults and children.¹ Acute ITP is the most common form, which happens in the presence of a precipitant, leading to a drop in platelet counts. However, chronic ITP can occur when all the causes that might precipitate thrombocytopenia have been ruled out, and it is persistent for ≥ 12 months.² Its presence can mask other diseases that exhibit somewhat similar signs and symptoms. We present a case of a patient presenting with chronic ITP with diffuse rash and was later diagnosed with idiopathic leukocytoclastic vasculitis (LCV).

Case Presentation

A 79-year-old presented to the hospital with 2-day history of a rash. The rash was purpureal and petechial and located on the trunk and bilateral upper and lower extremities. The rash was associated with itchiness and pain in the wrists, ankles, and small joints of the hands. The patient reported no changes in medication or diet, no recent upper respiratory tract or gastrointestinal infections, fever or chills, night sweats, or weight loss. The patient’s medical history consisted of thrombocytopenia about 5 years before and since then had been following up with a hematologist and underwent an extensive workup, including bone marrow biopsy without a definite diagnosis.

The patient mentioned that at the time of diagnosis the platelet count was about 90,000 but had been fluctuating between 50 and 60,000 recently. The patient also reported no history of gum bleeding, nosebleeds, hemoptysis, hematemesis, or any miscarriages. She also had difficulty voiding for 2 to 3 days but no dysuria, frequency, urgency, or incontinence.

The patient was diagnosed with a urinary tract infection (UTI) 1 day before presentation and was started on ciprofloxacin 500 mg daily for 5 days. Her home medications included diphenhydramine as needed, metoprolol, and levothyroxine 125 µg. Her medical history was significant for hypertension, bradycardia with pacemaker placement, and obstructive sleep apnea. There were no noteworthy elements in her family and social history.

Laboratory results were significant for 57,000/µL platelet count (normal range, 150,000-450,000), elevated d-dimer (6.07), < 6 mg/dL C4 (normal range, 88-201). Hemoglobin level, coagulation panel, hemolytic panel, and fibrinogen level results were unremarkable. The hepatitis panel, Lyme disease, and HIV test were negative. The peripheral blood smear showed moderate thrombocytopenia, mild monocytosis, and borderline normochromic normocytic anemia without schistocytes. The autoimmune panel to evaluate thrombocytopenia showed platelet antibody against glycoprotein (GP) IIb/IIIa, GP Ib/Ix, GP Ia/IIa, suggestive toward a diagnosis of chronic idiopathic ITP. However, the skin biopsy of the rash was indicative of LCV.

An autoimmune panel for vasculitis, including antinuclear antibody and antidouble-stranded DNA, was negative. While in the hospital, the patient completed the course of ciprofloxacin for the UTI, the rash started to fade without any intervention, and the platelet count improved to 69,000/µL. The patient was discharged after 3 days with the recommendation to follow up with her hematologist.

Discussion

LCV is a small vessel vasculitis of the dermal capillaries and venules. Histologically, LCV is characterized by fibrinoid necrosis of the vessel wall with frequent neutrophils, nuclear dust, and extravasated erythrocytes.³

Although a thorough evaluation is recommended to determine etiology, about 50% of cases are idiopathic. The most common precipitants are acute infection or a new medication. Postinfectious LCV is most commonly seen after streptococcal upper respiratory tract infection. Among other infectious triggers, Mycobacterium, Staphylococcus aureus, chlamydia, Neisseria, HIV, hepatitis B, hepatitis C, and syphilis are noteworthy. Foods, autoimmune disease, collagen vascular disease, and malignancy are also associated with LCV.⁴

In our patient we could not find any specific identifiable triggers. However, the presence of a UTI as a precipitating factor cannot be ruled out.⁵ Moreover, the patient received ciprofloxacin and there have been several case reports of LCV associated with use of a fluroquinolone.⁶ Nevertheless, in the presence of chronic ITP, which also is an auto-immune condition, an idiopathic cause seemed a reasonable explanation for the patient’s etiopathogenesis.

The cutaneous manifestations of LCV may appear about 1 to 3 weeks after the triggering event if present. The major clinical findings include palpable purpura and/or petechiae that are nonblanching. These findings can easily be confused with other diagnoses especially in the presence of a similar preexisting diagnosis. For example, our patient already had chronic ITP, and in such circumstances, a diagnosis of superimposed LCV can be easily missed without a thorough investigation. Extracutaneous manifestations with LCV are less common. Systemic symptoms may include low-grade fevers, malaise, weight loss, myalgia, and arthralgia. These findings have been noted in about 30% of affected patients, with arthralgia the most common manifestation.⁷ Our patient also presented with pain involving multiple joints.

The mainstay of diagnosis for LCV is a skin biopsy with direct immunofluorescence. However, a workup for an underlying condition should be considered based on clinical suspicion. If a secondary cause is found, management should target treating the underlying cause, including withdrawal of the offending drug, treatment or control of the underlying infection, malignancy, or connective tissue disease. Most cases of idiopathic cutaneous LCV resolve with supportive measures, including leg elevation, rest, compression stockings, and antihistamines. In resistant cases, a 4- to 6-week tapering dose of corticosteroids and immunosuppressive steroid-sparing agents may be needed.⁸

Conclusions

Although most cases of LCV are mild and resolve without intervention, many cases go undiagnosed due to a delay in performing a biopsy. However, we should always look for the root cause of a patient’s condition to rule out underlying contributing conditions. Differentiating LCV from any other preexisting condition presenting similarly is important.

Idiopathic thrombocytopenic purpura (ITP) is an immune-mediated acquired condition affecting both adults and children.¹ Acute ITP is the most common form, which happens in the presence of a precipitant, leading to a drop in platelet counts. However, chronic ITP can occur when all the causes that might precipitate thrombocytopenia have been ruled out, and it is persistent for ≥ 12 months.² Its presence can mask other diseases that exhibit somewhat similar signs and symptoms. We present a case of a patient presenting with chronic ITP with diffuse rash and was later diagnosed with idiopathic leukocytoclastic vasculitis (LCV).

Case Presentation

A 79-year-old presented to the hospital with 2-day history of a rash. The rash was purpureal and petechial and located on the trunk and bilateral upper and lower extremities. The rash was associated with itchiness and pain in the wrists, ankles, and small joints of the hands. The patient reported no changes in medication or diet, no recent upper respiratory tract or gastrointestinal infections, fever or chills, night sweats, or weight loss. The patient’s medical history consisted of thrombocytopenia about 5 years before and since then had been following up with a hematologist and underwent an extensive workup, including bone marrow biopsy without a definite diagnosis.

The patient mentioned that at the time of diagnosis the platelet count was about 90,000 but had been fluctuating between 50 and 60,000 recently. The patient also reported no history of gum bleeding, nosebleeds, hemoptysis, hematemesis, or any miscarriages. She also had difficulty voiding for 2 to 3 days but no dysuria, frequency, urgency, or incontinence.

The patient was diagnosed with a urinary tract infection (UTI) 1 day before presentation and was started on ciprofloxacin 500 mg daily for 5 days. Her home medications included diphenhydramine as needed, metoprolol, and levothyroxine 125 µg. Her medical history was significant for hypertension, bradycardia with pacemaker placement, and obstructive sleep apnea. There were no noteworthy elements in her family and social history.

Laboratory results were significant for 57,000/µL platelet count (normal range, 150,000-450,000), elevated d-dimer (6.07), < 6 mg/dL C4 (normal range, 88-201). Hemoglobin level, coagulation panel, hemolytic panel, and fibrinogen level results were unremarkable. The hepatitis panel, Lyme disease, and HIV test were negative. The peripheral blood smear showed moderate thrombocytopenia, mild monocytosis, and borderline normochromic normocytic anemia without schistocytes. The autoimmune panel to evaluate thrombocytopenia showed platelet antibody against glycoprotein (GP) IIb/IIIa, GP Ib/Ix, GP Ia/IIa, suggestive toward a diagnosis of chronic idiopathic ITP. However, the skin biopsy of the rash was indicative of LCV.

An autoimmune panel for vasculitis, including antinuclear antibody and antidouble-stranded DNA, was negative. While in the hospital, the patient completed the course of ciprofloxacin for the UTI, the rash started to fade without any intervention, and the platelet count improved to 69,000/µL. The patient was discharged after 3 days with the recommendation to follow up with her hematologist.

Discussion

LCV is a small vessel vasculitis of the dermal capillaries and venules. Histologically, LCV is characterized by fibrinoid necrosis of the vessel wall with frequent neutrophils, nuclear dust, and extravasated erythrocytes.³

Although a thorough evaluation is recommended to determine etiology, about 50% of cases are idiopathic. The most common precipitants are acute infection or a new medication. Postinfectious LCV is most commonly seen after streptococcal upper respiratory tract infection. Among other infectious triggers, Mycobacterium, Staphylococcus aureus, chlamydia, Neisseria, HIV, hepatitis B, hepatitis C, and syphilis are noteworthy. Foods, autoimmune disease, collagen vascular disease, and malignancy are also associated with LCV.⁴

Women with polycystic ovary syndrome (PCOS) may be at a higher risk of developing pancreatic cancer, say researchers reporting a single-center case-control study.

A diagnosis of PCOS was associated with a 1.9-fold higher risk of pancreatic cancer after adjusting for age, race, ethnicity, estrogen level, and diabetes.

This is the second study to find such an association.

“Our study findings combined with those from the 2019 Swedish Registry study offer compelling evidence that PCOS may be a novel risk factor for pancreatic cancer,” said corresponding author Mengmeng Du, ScD, department of epidemiology and biostatistics, Memorial Sloan Kettering Cancer Center.

“These data suggest some individuals may have unknown metabolic derangements that may underlie the development of both conditions,” the team concluded.

The findings were published in JAMA Oncology.

Approached for comment, Srinivas Gaddam, MD, MPH, associate director of pancreatic biliary research medicine, Cedars-Sinai, suggested that the findings may pave the way for a better understanding of the two diseases, but he emphasized that more research is needed.

“I think there’s more research to be done because now we’re seeing more younger women get pancreatic cancer,” Dr. Gaddam said. “So that makes it interesting whether PCOS itself contributes to pancreatic cancer. I still think the jury is out there.”

Dr. Gaddam drew attention to the confidence interval for the finding – the adjusted odds ratio was 1.88 (95% confidence interval, 1.02-3.46). “Because their odds ratio includes 1, I’m left with the question as to whether or not this is truly associated. I’m not certain that we can draw any conclusions based on this,” he commented.

The investigators acknowledge that they did “not observe statistically significant interactions” and comment that “prospective studies are needed to examine underlying biologic mechanisms and confirm our findings.”

For the study, the team used data from the Memorial Sloan Kettering Cancer Center Pancreatic Tumor Registry. They identified patients with pancreatic cancer who also self-reported a diagnosis of PCOS.

The investigators compared data from 446 women with pathologically or cytologically confirmed pancreatic adenocarcinoma with 209 women who had no history of cancer. The mean age at cancer diagnosis or enrollment was 63.8 years among patients with pancreatic cancer and 57.7 years in the control group.

The study found that having PCOS nearly doubled a person’s risk of developing pancreatic cancer.

When adjusted for type 2 diabetes diagnosis, the odds ratio fell slightly to 1.78 (95% CI, 0.95-3.34).

Dr. Du, along with lead author Noah Peeri, PhD, were surprised that even after adjusting for body mass index and the presence of type 2 diabetes, PCOS remained strongly associated with pancreatic cancer risk.

“We originally thought type 2 diabetes may drive this association, given more than half of those with PCOS develop type 2 diabetes by age 40, according to the CDC, and type 2 diabetes has also been linked with increased pancreatic cancer risk,” said Dr. Du.

“While the association was slightly weaker and no longer statistically significant after we controlled for type 2 diabetes, the magnitude of the association remained largely unchanged,” he said.

Dr. Peeri believes that some of the factors that have been causally related to PCOS may increase an individual’s pancreatic cancer risk.

“PCOS itself does not likely cause pancreatic cancer, but metabolic problems (for example, improper breakdown of insulin) and chronic inflammation can contribute to both PCOS and pancreatic cancer risk,” Dr. Peeri said.

He concluded that the study results “suggest other underlying metabolic dysfunction may increase an individual’s pancreatic cancer risk.”

An important limitation of this study was that women in the study self-reported PCOS and may have incorrectly recalled their diagnosis. However, the authors believe it is unlikely that that had a bearing on the study findings.

The study was supported by National Cancer Institute grants, the Geoffrey Beene Foundation, and the Arnold and Arlene Goldstein Family Foundation.

Response-adapted de-escalation of immunotherapy in patients with advanced melanoma may lead to considerable savings for payers – close to $20,000 per patient – compared with standard immunotherapy, an economic analysis found.

“The rising costs of cancer therapies are becoming untenable for both patients and payers, and there is both clinical and economic benefit to finding less expensive treatment alternatives,” Wolfgang Kunz, MD, University Hospital, Ludwig Maximilian University of Munich, told this news organization.

This economic analysis “highlights that leveraging modern diagnostic capabilities can do just that: Pairing drug regimens with CT-image analysis to optimize dosages can reduce health care costs and improve clinical outcomes,” Dr. Kunz said.

The study was published online in JAMA Dermatology.

While the use of immunotherapies over the past decade has improved the prognosis for patients with advanced melanoma, these drugs come with a hefty price tag.

One potential way to help reduce costs: de-escalate therapy. The ADAPT-IT trial demonstrated similar progression-free and overall survival among patients who received response-adapted ipilimumab discontinuation and those who received standard of care.

In the current analysis, Dr. Kunz and colleagues wanted to understand whether this response-adapted approach was also cost effective.

The team applied economic modeling to data from the ADAPT-IT trial as well as CheckMate 067, in which patients received standard of care four doses of combination ipilimumab-nivolumab followed by nivolumab monotherapy. In the ADAPT-IT trial, patients also initially received the immunotherapy combination but had CT scans to determine their response after two doses; if they responded, patients discontinued ipilimumab and continued with nivolumab monotherapy.

Overall, ADAPT-IT showed that responders could forgo the additional two doses of ipilimumab plus nivolumab while maintaining similar progression-free survival and overall survival seen at 18 months in the CheckMate 067 trial.

The current economic analysis, based on 41 patients from ADAPT-IT and 314 from CheckMate 067, showed a potential reduction in health care costs of $19,891 per patient with the response-adapted approach.

Response-adapted treatment was the cost-effective option in 94% of simulated scenarios.

When extrapolated to 2019 incidence rates of distant melanoma cases, yearly national savings could reach about $58 million.

“In the relatively small space of immunotherapies in advanced melanoma, we hope this analysis motivates clinicians to consider response-adapted treatment,” Dr. Kunz told this news organization.

“On the larger scale, this analysis serves as a stepping stone to more response-guided treatment protocols,” Dr. Kunz added. “With drug costs rising and imaging capabilities growing, more frequent image-guided adjustments are a perfect fit into the personalized care model.”

When applying the cost savings noted in this analysis across all treated patients, “the economic impact may be profound,” said Joseph Skitzki, MD, surgical oncologist, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., who wasn’t involved in the study. The “financial toxicity of cancer care is increasingly recognized as a potential barrier to optimal outcomes and any measures to mitigate cost may be impactful.”

However, Dr. Skitzki said several caveats need to be considered.

One is that the data included from ADAPT-IT only included 41 patients, compared with 314 patients from CheckMate 067.

“It is possible that a larger real-world study utilizing the ADAPT-IT protocol may not be as favorable in terms of outcomes and could lessen the economic impact of de-escalation, although any form of de-escalation is likely to have a cost benefit,” Dr. Skitzki said in an interview.

A real-world response–adapted de-escalation clinical trial, with an emphasis on costs and a benchmark of similar progression-free and overall survival, should be conducted before the de-escalated option becomes “practice changing,” Dr. Skitzki said.

Jeffrey Weber, MD, PhD, deputy director, Perlmutter Cancer Center, NYU Langone Health, New York, also urged caution in interpreting the results.

“I would not base treatment decisions on a small sampling of 41 patients in the absence of a randomized comparison,” Dr. Weber told this news organization. “Without a proper comparison, I would not advocate using only two doses of ipilimumab-nivolumab to make decisions on treatment.”

Dr. Skitzki added that, while “studies like this one are desperately needed to lessen the economic impact of new and emerging combination immunotherapies,” there is likely also a “disincentive for pharmaceutical companies to conduct this type of research.”

This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

Dr. Skitzki added that, while “studies like this one are desperately needed to lessen the economic impact of new and emerging combination immunotherapies,” there is likely also a “disincentive for pharmaceutical companies to conduct this type of research.”

This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

Response-adapted de-escalation of immunotherapy in patients with advanced melanoma may lead to considerable savings for payers – close to $20,000 per patient – compared with standard immunotherapy, an economic analysis found.

“The rising costs of cancer therapies are becoming untenable for both patients and payers, and there is both clinical and economic benefit to finding less expensive treatment alternatives,” Wolfgang Kunz, MD, University Hospital, Ludwig Maximilian University of Munich, told this news organization.

This economic analysis “highlights that leveraging modern diagnostic capabilities can do just that: Pairing drug regimens with CT-image analysis to optimize dosages can reduce health care costs and improve clinical outcomes,” Dr. Kunz said.

The study was published online in JAMA Dermatology.

While the use of immunotherapies over the past decade has improved the prognosis for patients with advanced melanoma, these drugs come with a hefty price tag.

One potential way to help reduce costs: de-escalate therapy. The ADAPT-IT trial demonstrated similar progression-free and overall survival among patients who received response-adapted ipilimumab discontinuation and those who received standard of care.

In the current analysis, Dr. Kunz and colleagues wanted to understand whether this response-adapted approach was also cost effective.

The team applied economic modeling to data from the ADAPT-IT trial as well as CheckMate 067, in which patients received standard of care four doses of combination ipilimumab-nivolumab followed by nivolumab monotherapy. In the ADAPT-IT trial, patients also initially received the immunotherapy combination but had CT scans to determine their response after two doses; if they responded, patients discontinued ipilimumab and continued with nivolumab monotherapy.

Overall, ADAPT-IT showed that responders could forgo the additional two doses of ipilimumab plus nivolumab while maintaining similar progression-free survival and overall survival seen at 18 months in the CheckMate 067 trial.

The current economic analysis, based on 41 patients from ADAPT-IT and 314 from CheckMate 067, showed a potential reduction in health care costs of $19,891 per patient with the response-adapted approach.

Response-adapted treatment was the cost-effective option in 94% of simulated scenarios.

When extrapolated to 2019 incidence rates of distant melanoma cases, yearly national savings could reach about $58 million.

“In the relatively small space of immunotherapies in advanced melanoma, we hope this analysis motivates clinicians to consider response-adapted treatment,” Dr. Kunz told this news organization.

“On the larger scale, this analysis serves as a stepping stone to more response-guided treatment protocols,” Dr. Kunz added. “With drug costs rising and imaging capabilities growing, more frequent image-guided adjustments are a perfect fit into the personalized care model.”

When applying the cost savings noted in this analysis across all treated patients, “the economic impact may be profound,” said Joseph Skitzki, MD, surgical oncologist, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., who wasn’t involved in the study. The “financial toxicity of cancer care is increasingly recognized as a potential barrier to optimal outcomes and any measures to mitigate cost may be impactful.”

However, Dr. Skitzki said several caveats need to be considered.

One is that the data included from ADAPT-IT only included 41 patients, compared with 314 patients from CheckMate 067.

“It is possible that a larger real-world study utilizing the ADAPT-IT protocol may not be as favorable in terms of outcomes and could lessen the economic impact of de-escalation, although any form of de-escalation is likely to have a cost benefit,” Dr. Skitzki said in an interview.

A real-world response–adapted de-escalation clinical trial, with an emphasis on costs and a benchmark of similar progression-free and overall survival, should be conducted before the de-escalated option becomes “practice changing,” Dr. Skitzki said.

Jeffrey Weber, MD, PhD, deputy director, Perlmutter Cancer Center, NYU Langone Health, New York, also urged caution in interpreting the results.

“I would not base treatment decisions on a small sampling of 41 patients in the absence of a randomized comparison,” Dr. Weber told this news organization. “Without a proper comparison, I would not advocate using only two doses of ipilimumab-nivolumab to make decisions on treatment.”

Adults with chronic gastroesophageal reflux disease (GERD) are at increased risk for Barrett’s esophagus (BE) – the precursor to esophageal adenocarcinoma (EAC) – but most don’t undergo recommended screening, new research shows.

Jennifer Kolb, MD, with the University of California, Los Angeles, and colleagues surveyed 472 adults with chronic GERD who qualify for BE screening and had a recent visit with their primary care provider.

In this diverse population of people at risk for BE and EAC, only 13% had ever been advised to undergo endoscopy to screen for BE and only 5% actually had a prior screening, the study notes.

“These results make it clear that screening is rarely done,” Dr. Kolb told this news organization.

The results of the survey are published online in the American Journal of Gastroenterology.
 

Concern high, understanding low

Esophageal cancer and BE have increased among middle-aged adults over roughly the past 5 years, and this increase is not because of better or more frequent screening, as reported previously by this news organization.

In fact, the majority of patients who develop EAC do not have a prior diagnosis of BE, which highlights the failure of current BE screening practices, Dr. Kolb and colleagues point out.

Professional gastroenterology society guidelines recommend screening for BE using upper endoscopy for at-risk individuals, which includes those with chronic GERD, along with other risk factors such as age older than 50 years, male sex, white race, smoking, obesity, and family history of BE or EAC.

In the current survey, most individuals said early detection of BE/EAC is important and leads to better outcomes, but most had poor overall knowledge of risk factors and indications for screening.

Only about two-thirds of respondents correctly identified BE risk factors, and only about 20% believed BE screening was necessary with GERD, the researchers note.

Roughly two-thirds of individuals wanted to prioritize BE screening and felt that getting an upper endoscopy would ease their concern.

Yet, 40% had no prior esophagogastroduodenoscopy. These individuals were less knowledgeable about BE/EAC risk and screening recommendations and identified more barriers to completing endoscopy.

“While minorities were most concerned about developing Barrett’s esophagus and cancer, they reported more barriers to screening compared to White participants,” Dr. Kolb said.
 

Addressing knowledge gaps

The primary care clinician is often the first line for patients with symptomatic acid reflux and the gateway for preventive cancer screening.

Yet, research has shown that primary care clinicians often have trouble identifying who should be screened for BE, and competing clinical issues make it challenging to implement BE screening.

“As gastroenterologists, we must partner with our primary care colleagues to help increase awareness of this lethal disease and improve recognition of risk factors so that eligible patients can be identified and referred for screening,” Dr. Kolb said.

Reached for comment, Seth Gross, MD, clinical chief of the division of gastroenterology and hepatology at New York University Langone Health, said the results “shed light on the fact that patients with GERD don’t have the knowledge of when they should get medical attention and possibly endoscopy.”

“We may need to do a better job of educating our colleagues and patients to know when to seek specialists to potentially get an endoscopy,” Dr. Gross said.

About 90% of esophageal cancers are diagnosed outside of surveillance programs, noted Prasad G. Iyer, MD, a gastroenterologist at Mayo Clinic in Rochester, Minn.

“Patients didn’t even know that they had Barrett’s [esophagus], so they were never under surveillance. They only come to attention after they have trouble with food sticking, and they can’t swallow solid food,” said Dr. Iyer, who wasn’t involved in the survey.

“Unfortunately, there are just so many cancers and so many issues that primary care providers have to deal with that I think this may not be getting the attention it deserves,” he said.

Access to endoscopy is also likely a barrier, Dr. Iyer noted.

“The waiting list may be several months, and I think providers may focus on other things,” he said.
 

Less-invasive screening options

Fear of endoscopy may be another issue.

In their survey, Dr. Kolb and colleagues found that 20% of respondents reported fear of discomfort with endoscopy as a barrier to completing screening.

But less-invasive screening options are increasingly available or in development.

This includes Cytosponge, a swallowable capsule containing a compressed sponge attached to a string. When withdrawn, the sponge contains esophageal cytology samples that can be used to identify biomarkers for BE.

In a guideline released last spring, the American College of Gastroenterology endorsed Cytosponge as a nonendoscopic BE screening modality, as published in the American Journal of Gastroenterology.

“The strength of the recommendation is conditional, but it’s the first time where [the ACG] is saying that this may be an option for people,” Dr. Gross said.

This research was funded by the American College of Gastroenterology. Dr. Kolb, Dr. Gross, and Dr. Iyer report no relevant financial relationships.
