A new index of frailty predicts survival in older patients with multiple myeloma based on accumulation of aging-associated deficits, rather than chronological age alone, investigators report. A 16% increased risk of death was seen for each 10% increase in the deficit-accumulation frailty index (DAFI), which includes 25 variables related health, function, and activities of daily living.

There was only a weak correlation between chronological age and increase in deficits tracked by the index, in contrast to a cohort without cancer, in which age and frailty were strongly correlated, the investigators reported in JCO Clinical Cancer Informatics.

“Our results demonstrate that, for patients with multiple myeloma, chronological age alone is not a good measure for assessing overall health,” study author Tanya M. Wildes, MD, of Washington University, St. Louis, said in a news release from the American Society of Clinical Oncology.

Existing tools to assess frailty include an index proposed by the International Myeloma Working Group that looks at age plus other indexes related to comorbidities and activities of daily living, and the revised Myeloma Comorbidity Index that incorporates age with other prognostic factors.

“Although both tools provide prognostic information, chronological age automatically increases frailty without taking biologic or functional age into account,” Dr. Wildes and her coauthors wrote in their report.

By contrast, the DAFI is based on the concept of biologic age, in which the health status of an individual is measured based on the proportion of aging-associated deficits they have accumulated, according to the authors.

To create the DAFI, Dr. Wildes and her colleagues analyzed nearly 2.7 million records of noncancer patients aged 66 years or older in the SEER Medicare Health Outcomes Survey (MHOS) database. They identified 25 variables in the database representing chronic health conditions, activities of daily living, functioning, mental health, and general health.

An individual’s DAFI score was calculated as the sum of scores for each of the 25 variables as 0 for absent, 0.5 for limited, and 1 for present. Predicted DAFI means were calculated for each year of age and used to create age-specific cut points to determine whether an individual would be considered frail or not versus others of the same age.

“In other words, the same frailty score may qualify an 80-year-old individual as fit and a 70-year-old as frail, depending on the cutoff for their respective age group,” investigators explained in their report.

They applied the index to 305 patients with newly diagnosed myeloma in the SEER-MHOS database who were 66 years of age or older (median age, 76 years) and had completed the survey within 1 year of diagnosis.

The DAFI classified 52% of the myeloma patients as frail, and for that group, median overall survival was 26.8 months, versus 43.7 months for nonfrail patients (P = .015), according to the reported data. For each 10% increase in score, the risk of death increased by 16% (P less than .001).

Notably, advancing age was very weakly correlated with increased age-related deficits in the myeloma cohort (r2 = 0.15; P = .010), according to investigators, but very strongly correlated with deficits in the cohort of noncancer patients (r2 = 0.98; P less than .001).

“This suggests that, in patients with multiple myeloma, the prevalence of impairments across domains of function, chronic comorbidities, general health, and mental health are more related to the overall burden of myeloma rather than chronological age alone,” the investigators wrote.

The information used to calculate a DAFI score is easily obtainable during a clinic visit, according to the authors, who provided an overview of all 25 variables in the journal article.

Further development of a computerized program would further enhance usability in the clinic, allowing for real-time calculation during a patient visit, they said.

Survivorship expert Merry Jennifer Markham, MD, said in the ASCO news release that this frailty index is notable because it accounts for more than just chronological age. “Knowing this information can help oncologists have more informed discussions with patients about their prognosis, which in turn can empower patients and families as they weigh treatment options,” she said.

The research was supported by National Cancer Institute. Dr. Wildes reported honoraria from Carevive Systems and research funding from Janssen Oncology. Another coauthor reported honoraria from Celgene and Janssen, and a consulting or advisory role with Amgen and Takeda.

Low serum bicarbonate and lower platelet count were among the factors that predicted a longer hospital length of stay among pediatric patients with high risk or very high risk acute lymphoblastic leukemia (ALL) who were treated with four-drug induction therapy.

©pixelcarpenter/Fotolia.com

Kasper Warrick, MD, and his colleagues at Indiana University in Indianapolis reported findings from a retrospective study of 73 ALL patients at their hospital. They performed chart reviews comparing a cohort of 42 patients who were discharged on day 4 of their induction treatment with 31 similar patients who had a longer hospital stay or admission to the intensive care unit. The report was published in Leukemia Research.

Univariate analysis found that patients with a longer length of stay were more likely to have a fever, pretransfusion hemoglobin of less than 8 g/dL, lower serum bicarbonate values, abnormal serum calcium, and abnormal serum phosphate. Multivariate stepwise logistic regression found that low serum bicarbonate and a lower platelet count on day 4 of admission was predictive of a prolonged hospital stay. About a third of patients from each group had an unplanned readmission within 30 days.

The researchers concluded that early discharge is safe in only a subgroup of high-risk ALL patients undergoing induction chemotherapy. “Treating physicians could opt for a discharge only after normalization of electrolyte abnormalities and renal functions, and when no transfusion support is needed (stable hematocrit and platelet count),” they wrote. Even in those cases, they recommended “aggressive and close outpatient follow” since patients are vulnerable to complications and readmissions.

Ixazomib significantly improved progression-free survival as a maintenance therapy in adults with multiple myeloma who had responded to high-dose therapy and autologous stem cell transplant.

The drug’s sponsor, Takeda, announced that the oral proteasome inhibitor had met the primary endpoint – progression-free survival versus placebo – in the randomized, phase 3 TOURMALINE-MM3 study. They also reported that adverse events were consistent with previously reported results for single-agent use of ixazomib and that there were no new safety signals.

Full study results will be presented at the annual meeting of the American Society of Hematology. Company officials plan to submit the trial data to the Food and Drug Administration and regulatory agencies around the world to gain approval of ixazomib as a single-agent maintenance therapy, according to a Takeda announcement.

The TOURMALINE-MM3 study is a double-blind study of 656 patients with multiple myeloma who have had complete response, very good partial response, or partial response to induction therapy followed by high-dose therapy and autologous stem cell transplant. In addition to progression-free survival, the trial assessed overall survival.

Individuals who develop acute myeloid leukemia (AML) may have somatic mutations detectable years before diagnosis, a newly published analysis shows.

Mutations in IDH1, IDH2, TP53, DNMT3A, TET2, and spliceosome genes at baseline assessment increased the odds of developing AML with a median follow-up of 9.6 years in the study, which was based on blood samples from participants in the Women’s Health Initiative (WHI).

The findings suggest a “premalignant landscape of mutations” that may precede overt AML by many years, according to Pinkal Desai, MD, assistant professor of medicine at Cornell University and oncologist at New York–Presbyterian/Weill Cornell Medical Center, New York, and her coauthors.

“The ability to detect and identify high-risk mutations suggests that monitoring strategies for patients, as well as clinical trials of potentially preventative or disease-intercepting interventions should be considered,” wrote Dr. Desai and her colleagues. The report was published in Nature Medicine.

Their analysis comprised 212 women who participated in the WHI who were healthy at the baseline evaluation but went on to develop AML during follow-up. They performed deep sequencing on peripheral blood DNA for these cases and for 212 age-matched controls.

Women who developed AML were more likely than were controls to have mutations in baseline assessment (odds ratio, 4.86; 95% confidence interval, 3.07-7.77), and had demonstrated greater clonal complexity versus controls (comutations in 46.8% and 5.5%, respectively; odds ratio, 9.01; 95% CI, 4.1-21.4), investigators found.

All 21 patients with TP53 mutations went on to develop AML, as did all 15 with IDH1 or IDH2 mutations and all 3 with RUNX1 mutations. Multivariate analysis showed that TP53, IDH1 and IDH2, TET2, DNMT3A and several spliceosome genes were associated with significantly increased odds of AML versus controls.

Based on these results, Dr. Desai and colleagues proposed that patients at increased AML risk should be followed in long-term monitoring studies that incorporate next-generation sequencing.

“Data from these studies will provide a robust rationale for clinical trials of preventative intervention strategies in populations at high risk of developing AML,” they wrote.

In clinical practice, monitoring individuals for AML-associated mutations will become more feasible as costs decrease and new therapies with favorable toxicity profiles are introduced, they added.

“Molecularly targeted therapy is already available for IDH2 mutations and is under development for mutations in other candidate genes found in this study including IDH1, TP53 and spliceosome genes,” they wrote.

The authors reported having no relevant financial disclosures. The WHI program is funded by the National Institutes of Health.

A 70-year-old man underwent salvage therapy for multiple myeloma (MM). While on maintenance immunotherapy he developed a sternal plasmacytoma. After the fifth cycle of treatment, he developed swelling, erythema, and pain in his right testis.

The main differential diagnoses for those symptoms are infections and tumors; infection is more common, so his clinicians at Indiana University School of Medicine presumed orchitis and started him on IV antibiotics. The pain resolved, but the swelling persisted after the antibiotic course. The clinicians turned to biochemical marker screening for germ cell tumors, but those were negative. Serial ultrasound imaging, which they had begun during his admission, remained unchanged.

Meanwhile, the patient’s chemotherapy was being held back, and he developed another sternal mass, prompting a fluorodeoxyglucose-positron emission tomography–computed tomography (PET/CT) scan to evaluate for relapse of myeloma. The scan revealed an enlarged, diffusely hypermetabolic right testicle. Believing the symptoms were related to the myeloma and not orchitis, the clinicians advised a radical orchiectomy.

A biopsy after the surgery showed tumor cells consistent with testicular plasmacytoma.

While rare, testicular plasmacytoma is commonly associated with MM, especially in the later stages, when cancer cells are more aggressive and not relying on bone marrow for survival, the clinicians say. Unlike myeloma, which typically spreads via blood to bone sites, testicular plasmacytoma may spread via lymphatic channels to the regional lymph nodes and subsequently to distant sites, the clinicians add, similarly to lymphoma or germ cell tumor.

It is hard to diagnose, though. The clinicians say the patient’s case illustrates the challenges. Imaging studies such as ultrasound and CT scans are not specific. And although FDG-PET/CT imaging is a standard staging tool for myeloma and helpful in identifying plasmacytoma when evidenced as intramedullary or extramedullary hypermetabolic lesions, hypermetabolic lesions are not always malignant, they note. FDG-PET/CT can’t differentiate between orchitis and testicular plasmacytoma.  Biopsy remains the diagnostic gold standard.

The main differential diagnoses for those symptoms are infections and tumors; infection is more common, so his clinicians at Indiana University School of Medicine presumed orchitis and started him on IV antibiotics. The pain resolved, but the swelling persisted after the antibiotic course. The clinicians turned to biochemical marker screening for germ cell tumors, but those were negative. Serial ultrasound imaging, which they had begun during his admission, remained unchanged.

Meanwhile, the patient’s chemotherapy was being held back, and he developed another sternal mass, prompting a fluorodeoxyglucose-positron emission tomography–computed tomography (PET/CT) scan to evaluate for relapse of myeloma. The scan revealed an enlarged, diffusely hypermetabolic right testicle. Believing the symptoms were related to the myeloma and not orchitis, the clinicians advised a radical orchiectomy.

A biopsy after the surgery showed tumor cells consistent with testicular plasmacytoma.

While rare, testicular plasmacytoma is commonly associated with MM, especially in the later stages, when cancer cells are more aggressive and not relying on bone marrow for survival, the clinicians say. Unlike myeloma, which typically spreads via blood to bone sites, testicular plasmacytoma may spread via lymphatic channels to the regional lymph nodes and subsequently to distant sites, the clinicians add, similarly to lymphoma or germ cell tumor.

It is hard to diagnose, though. The clinicians say the patient’s case illustrates the challenges. Imaging studies such as ultrasound and CT scans are not specific. And although FDG-PET/CT imaging is a standard staging tool for myeloma and helpful in identifying plasmacytoma when evidenced as intramedullary or extramedullary hypermetabolic lesions, hypermetabolic lesions are not always malignant, they note. FDG-PET/CT can’t differentiate between orchitis and testicular plasmacytoma.  Biopsy remains the diagnostic gold standard.

CHICAGO – Chemoimmunotherapy for chronic lymphocytic leukemia is on the way out, but there’s one scenario where it still plays a key role, according to one leukemia expert.

That scenario is not in relapsed or refractory chronic lymphocytic leukemia (CLL), where the use of fludarabine, cyclophosphamide, and rituximab (FCR) may be hard to justify today. Data supporting use of FCR in relapsed CLL show a median progression-free survival (PFS) of about 21 months, Susan M. O’Brien, MD, of the University of California, Irvine, said at the annual meeting of the American Society of Clinical Oncology. There is also data for bendamustine-rituximab retreatment showing a median event-free survival of about 15 months, she added.

By contrast, the 5-year follow-up data for the Bruton tyrosine kinase inhibitor ibrutinib in the relapsed/refractory setting shows a median PFS of 52 months, which is “extraordinary,” given that the patients had a median of four prior regimens, Dr. O’Brien said.

Similarly, recently published results from the randomized, phase 3 MURANO study of venetoclax plus rituximab in relapsed/refractory CLL showed that median PFS was not reached at a median follow-up of 23.8 months, versus a median of 17 months for the bendamustine-rituximab comparison arm (N Engl J Med. 2018;378[12]:1107-20).

“Thanks to the MURANO study, we likely will have an expanded label for venetoclax that includes the combination of venetoclax and rituximab,” Dr. O’Brien said. “I think it’s quite clear that either of these is dramatically better than what you get with retreatment with chemotherapy, so I personally don’t think there is a role for chemoimmunotherapy in the relapsed patient.”

On June 8, 2018, the Food and Drug Administration granted regular approval for venetoclax for patients with CLL or small lymphocytic lymphoma, with or without 17p deletion, who have received at least one prior therapy. The FDA also approved its use in combination with rituximab.*

But frontline CLL treatment is currently a little bit more complicated, Dr. O’Brien said.

Recent studies show favorable long-term outcomes with FCR frontline therapy in the immunoglobulin heavy chain variable gene (IgHV) –mutated subgroup of patients, she noted.

The longest follow-up comes from a study from investigators at the University of Texas MD Anderson Cancer Center, Houston, published in 2016. In that study, the 12.8-year PFS was 53.9% for IgHV-mutated patients, versus just 8.7% for patients with unmutated IgHV. Of the IgHV-mutated group, more than half achieved minimal residual disease (MRD) negativity after treatment (Blood. 2016 Jan 21; 127[3]: 303-9).

“I’m going to go out on a limb and I’m going to suggest that I think there is a cure fraction here,” Dr. O’Brien said. “On the other hand, if there’s not a cure fraction and they’re going to relapse after 17 years, that’s a pretty attractive endpoint, even if it’s not a cure fraction.”

Clinical practice guidelines now recognize IgHV mutation status as an important marker that should be obtained when deciding on treatment, Dr. O’Brien noted.

For unmutated patients, the RESONATE-2 trial showed that ibrutinib was superior to chlorambucil in older patients, many of whom had comorbid conditions. In the 3-year update, median PFS was approximately 15 months for chlorambucil, while for ibrutinib the median PFS was “nowhere near” being reached, Dr. O’Brien said.

Those data may not be so relevant for fit, unmutated patients, and two randomized trials comparing FCR with bendamustine and rituximab have yet to report data. However, one recent cross-trial comparison found fairly overlapping survival curves for the two chemoimmunotherapy approaches.

Dr. O’Brien said she would put older patients with comorbidities on ibrutinib if a clinical trial was not available, and for fit, unmutated patients, while more data are needed, she would also use ibrutinib. However, patient preference sometimes tips the scale in favor of FCR.

“The discussions sometimes are quite long about whether the patient should opt to take ibrutinib or FCR,” Dr. O’Brien said. “The last patient I had that discussion with elected to take FCR. When I asked him why, he said because he liked the idea of being finished in six cycles, off all therapy, and hopefully in remission.”

While Dr. O’Brien said she views chemoimmunotherapy as still relevant in IgHV-mutated patients, eventually it will go away, she concluded. Toward that end, there is considerable interest in venetoclax plus ibrutinib, a combination that, in early reports, has yielded very encouraging MRD results in first-line CLL.

“We have no long-term data, but very, very exciting MRD negativity data,” Dr. O’Brien said.

Dr. O’Brien reported relationships with Abbvie, Amgen, Celgene, Gilead Sciences, Janssen, Pfizer, Pharmacyclics, Sunesis Pharmaceuticals, and others.

CHICAGO – The 10-year incidence rates for both squamous cell carcinoma and basal cell carcinoma arising after hematopoietic cell transplantation are impressively high at 17%-plus for each, but the malignancies occur on two very different timelines, according to Jeffrey F. Scott, MD, a fellow in micrographic surgery and dermatologic oncology at Case Western Reserve University in Cleveland.

Most of the squamous cell carcinomas (SCCs) in a large multicenter retrospective study developed within the first 5 years following hematopoietic cell transplantation (HCT), while the majority of the basal cell carcinomas (BCCs) occurred after that point, Dr. Scott reported at the annual meeting of the American College of Mohs Surgery.

He presented the results of the study, which included 876 HCT recipients followed for a mean of 6.1 years. The study objective was to pin down the risk factors for skin cancer after HCT, especially the patient-specific ones. This has become a pressing issue because the use of HCT is steadily growing, and the 5-year survival rate now exceeds 50%.

The transplant-specific risk factors have previously been fairly well described by others. They include the donor source, type of disease, the conditioning regimen, whether whole body irradiation was used, immunosuppression, graft versus host disease (GVHD), and others.

The patient-centric risk factors, in contrast, have not been well characterized. And it’s critical to thoroughly understand these risk factors in order to develop targeted prevention and surveillance strategies, Dr. Scott said.

“There remains a significant knowledge gap within our field. I would venture that the majority of this audience has treated a patient with skin cancer who has had a transplant,” he said. “Yet when a patient asks us, ‘Doc, what is my risk for skin cancer after my HCT?’ we’re really unable to give them an accurate and complete assessment of that risk. That’s because we’re missing the second major category of risk factors: the patient-specific risk factors.”

The reason for that, he added, is that the major population-based studies and national HCT registries are run by hematologists and oncologists, and they haven’t adequately captured the patient-specific skin cancer risk factors. But these are variables very familiar to dermatologists. They include skin phenotype, history of UV radiation exposure, and history of pre-HCT skin cancer.

Dr. Scott said the multicenter study he presented has two major advantages over prior studies: its large size and thorough followup. Nearly all 876 patients were followed by both an oncologist and a dermatologist at the same institution.

During followup, the HCT recipients collectively developed 63 SCCs, 55 BCCs, and 16 malignant melanomas. The 5- and 10-year incidence rates for SCC were 10.6% and 17.2%. For BCC, the 5- and 10-year rates were 5.7% and 17.6%. All 16 cases of melanoma occurred within 5 years after HCT.

In multivariate Cox proportional hazard analyses, photodamage documented on examination was independently associated with a 3.2-fold increased risk of post-HCT SCC and a 3.5-fold increased risk of BCC.

A pre-transplant history of BCC was associated with a 3.9-fold increased likelihood of developing a BCC afterwards. Similarly, a pre-HCT history of SCC conferred a 4.2-fold increased risk of post-transplant SCC and was also independently associated with a 6.6-fold increased risk of developing melanoma post-HCT.

Fitzpatrick skin types I and II were respectively associated with 9.3- and 7.2-fold increased risks of post-HCT nonmelanoma skin cancer, compared with skin types III-VI.

Acute GVHD wasn’t associated with an increased risk of nonmelanoma skin cancer after HCT. However, in an observation that hasn’t previously been reported by others, chronic GVHD with skin involvement was associated with a 2.7-fold increased likelihood of SCC post-HCT, Dr. Scott noted.

What’s next for Dr. Scott and his coinvestigators? “Our ultimate goal with this project is to develop an interactive risk assessment tool like the National Cancer Institute’s Breast Cancer Risk Assessment Tool that can be online and used by patients and providers to estimate their individualized risk of basal cell carcinoma, squamous cell carcinoma, and melanoma after HCT,” he said.

Dr. Scott reported having no financial conflicts related to the study.

CHICAGO – The JAK 1/2 inhibitor ruxolitinib (Jakafi), in combination with lenalidomide and methylprednisolone, overcame resistance to lenalidomide in about half of 28 heavily pre-treated patients with relapsed/refractory multiple myeloma, based on phase I trial results presented at the annual meeting of the American Society of Clinical Oncology (ASCO).

The clinical trial is the first to demonstrate the activity of a JAK inhibitor in the treatment of myeloma patients, according to investigator James R. Berenson, MD, medical and scientific director for the Institute for Myeloma & Bone Cancer Research (IMBCR), West Hollywood, Calif.

Andrew Bowser/MDedge News

These results are encouraging, though challenges remain, said Craig Hofmeister, MD, MPH, of Winship Cancer Institute, Emory University, Atlanta.

“Clearly in these patients who are 100% lenalidomide refractory, the overall response rate of anything greater than or close to 20, 30, 40% is very appealing,” Dr. Hofmeister said in an ASCO presentation discussing the results of this trial.

The usual rationale for JAK inhibition is targeting of the bone microenvironment, but the microenvironment is a formidable opponent, Dr. Hofmeister said in his presentation.

“That’s an uphill battle,” he said. “There is an upcoming carfilzomib and ruxolitinib trial in multiple myeloma moving forward, and I’d be excited to see” the results.

The study (NCT03110822) was sponsored by Oncotherapeutics in collaboration with Incyte, the maker of ruxolitinib (Jakafi). Dr. Berenson, the presenting author, had disclosures related to Incyte, as well as Amgen, Bristol-Myers Squibb, Celgene, Janssen, Takeda, and OncoTracker.

The study (NCT03110822) was sponsored by Oncotherapeutics in collaboration with Incyte, the maker of ruxolitinib (Jakafi). Dr. Berenson, the presenting author, had disclosures related to Incyte, as well as Amgen, Bristol-Myers Squibb, Celgene, Janssen, Takeda, and OncoTracker.

CHICAGO – The JAK 1/2 inhibitor ruxolitinib (Jakafi), in combination with lenalidomide and methylprednisolone, overcame resistance to lenalidomide in about half of 28 heavily pre-treated patients with relapsed/refractory multiple myeloma, based on phase I trial results presented at the annual meeting of the American Society of Clinical Oncology (ASCO).

The clinical trial is the first to demonstrate the activity of a JAK inhibitor in the treatment of myeloma patients, according to investigator James R. Berenson, MD, medical and scientific director for the Institute for Myeloma & Bone Cancer Research (IMBCR), West Hollywood, Calif.

These results are encouraging, though challenges remain, said Craig Hofmeister, MD, MPH, of Winship Cancer Institute, Emory University, Atlanta.

“Clearly in these patients who are 100% lenalidomide refractory, the overall response rate of anything greater than or close to 20, 30, 40% is very appealing,” Dr. Hofmeister said in an ASCO presentation discussing the results of this trial.

Janssen Biotech is launching a phase 1b/2 trial of an investigational chimeric antigen receptor (CAR) T-cell therapy for patients with relapsed or refractory multiple myeloma.

The trial, which was cleared by the Food and Drug Administration to begin in the second half of 2018, will evaluate the safety and efficacy of LCAR-B38M (JNJ-68284528). The CAR T therapy targets B-cell Maturation Antigen and expresses a CAR protein that is identical to a product that was developed by Legend Biotech and evaluated in a first-in-human clinical study in China.
