Whole-genome sequencing demonstrates clinical relevance
GLASGOW – Whole genome sequencing (WGS) appears capable of replacing cytogenetic testing and next generation sequencing (NGS) for the detection of clinically relevant molecular abnormalities in hematological malignancies, according to investigators.
A comparison of WGS with fluorescence in situ hybridization (FISH) showed that WGS caught all the same significant structural variants, plus some abnormalities that FISH had not detected, reported lead author Shirley Henderson, PhD, lead for cancer molecular diagnostics at Genomics England in Oxford.
Although further validation is needed, these findings, reported at the annual meeting of the British Society for Haematology, support an ongoing effort to validate the clinical reliability of WGS, which is currently reserved for research purposes.
“It’s vitally important that the clinical community engage with this and understand both the power and the limitations of this technique and how this work is going to be interpreted for the benefit of patients,” said Adele Fielding, PhD, session chair from University College London’s Cancer Institute.
The investigators compared WGS with FISH for detection of clinically significant structural variants (SVs) and copy number variants (CNVs) in tumor samples from 34 patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL).
The 252 standard of care FISH tests – conducted at three separate clinical diagnostic centers in the United Kingdom – included 138 SVs and 114 CNVs. WGS relied on a combination of bioinformatics and visual inspection of Circos plots. WGS confirmed all of the SVs detected by FISH with high confidence; WGS detected four additional SVs, also with high confidence, including an ETV6-RUNX1 fusion not detected by FISH because of probe limitations.
Results for CNVs were similar, with WGS detecting 78 out of 85 positive CNVs. Six of the missed positives were associated with low quality samples or low level mutations in the FISH test, suggesting that at least some positives may have been detected with better samples. Only one negative CNV from FISH was missed by WGS.
Overall, WGS had a false positive rate of less than 5% and a positive percentage agreement with FISH that exceeded 90%.
“Further work is required to fully validate all aspects of the WGS analysis pipeline,” Dr. Henderson said. “But these results indicate that WGS has the potential to reliably detect SVs and CNVs in these conditions while offering the advantage of detecting all SVs and CNVs present without the need for additional interrogation of the sample by multiple tests or probes.”
Dr. Henderson noted that there is really no “perfect method” for identifying structural and copy number variants at the present time.
Small variants are relatively easy to detect with techniques such as karyotyping and gene banding, but these tests have shortcomings, namely, that they require live cells and have “fairly high failure rates for various reasons,” Dr. Henderson said.
“FISH is an incredibly useful test and it has higher resolution than gene banding, but the problem with FISH is that you only find what you’re looking at,” Dr. Henderson said. “It’s not genome wide; it’s very targeted.”
Similarly, polymerase chain reaction (PCR), including next generation sequencing (NGS), can detect molecular abnormalities, but only those that are targeted, which may necessitate multiple tests, she said.
“If you start looking for all of the structural variants [with existing techniques], then you’re going to be doing an awful lot of tests,” Dr. Henderson said.
Another potential benefit of WGS is that it is “future resistant,” Dr. Henderson said. “As new biomarkers are discovered, you don’t have to redesign a new targeted test. It will also detect emerging biomarkers, such as mutational signatures and burden.”
The study was sponsored by NHS England. The investigators reported having no conflicts of interest.

For endometrial cancer, postop taxane/platinum competes with standard therapy
For patients with endometrial cancer at high risk of progression, receiving a combination of taxane and platinum chemotherapy after surgery offers similar efficacy and tolerability as doxorubicin and cisplatin, the standard therapy, according to a recent phase 3 trial.
Progression-free and overall survival rates were similar across treatment types, reported lead author Hiroyuki Nomura, MD, of Keio University, Tokyo, and his colleagues. The findings maintain doxorubicin/cisplatin as standard therapy; however, taxane/platinum chemotherapy could be a possible alternative for some patients because of similar efficacy and tolerability with a distinct toxicity profile.
“Establishment of evidence and validation of the optimal postoperative adjuvant chemotherapy regimen for endometrial cancer are important issues,” the investigators wrote in JAMA Oncology.
The multicenter, open-label study involved 788 patients with endometrial cancer at risk of progression, based on histologic findings. Eligibility required that patients have a residual tumor of at least 2 cm without extension beyond the abdominal cavity. Patients were randomly grouped into one of three treatment groups: doxorubicin/cisplatin, paclitaxel/carboplatin, or docetaxel/cisplatin. If tolerated, six 3-week cycles were given. The median follow-up period was 7 years. The primary and secondary endpoints were 5-year progression free survival and overall survival, respectively.
Survival rates were statistically similar between groups. The 5-year progression-free survival rate was 73.3% for doxorubicin/cisplatin, 73.9% for paclitaxel/carboplatin, and 79.0% for docetaxel/cisplatin (P = .12); the 5-year overall survival rate was 82.7% for doxorubicin/cisplatin, 86.1% for paclitaxel/carboplatin, and 88.1% for docetaxel/cisplatin (P = .67). Tolerability was also comparable, with a small range of discontinuation rates across treatment types, from 20.2% to 25.5% (P = .14).
“Although the superiority of docetaxel plus cisplatin and paclitaxel plus carboplatin over doxorubicin plus cisplatin was not demonstrated, we found that the three regimens were comparable in therapeutic effect,” the investigators concluded. “[C]onsidering efficacy and tolerability, taxane plus platinum regimens may be an alternative to treatment with doxorubicin plus cisplatin.”
The study was funded by a Health Labour Sciences Research Grant with nonspecific funding from AstraZeneca, Eisai, Bristol-Myers Squibb, and others. The investigators reported financial relationships with Chugai, Sanofi, Takeda, AbbVie, and others.

For patients with HBV, daily aspirin may reduce risk of liver cancer
Sixteen years of data showed that daily aspirin therapy reduced the risk of HBV-related HCC by 29%, reported lead author Teng-Yu Lee, MD, PhD, of Taichung (Taiwan) Veterans General Hospital and his colleagues. Analysis also showed that antiviral nucleos(t)ide analogue therapy and statin use were independently associated with reduced risk of HCC, whereas older age, cirrhosis, and male sex increased risk.
“Therapy with [nucleos(t)ide analogues] is associated with reductions in HCC risk, but the risk is not erased,” the investigators wrote in JAMA Internal Medicine. “Therefore, using only [nucleos(t)ide analogue] therapy may not be enough for HCC prevention. Antiviral therapy is not indicated in most HBV carriers, so another effective way of reducing HCC risk needs to be developed.”
Previous studies have shown that aspirin can reduce the risk of colorectal cancer; however, data supporting aspirin for HCC prevention are limited to a few animal models and human studies, the latter of which are statistically unreliable.
“Therefore, we conducted a nationwide cohort study to evaluate the association of daily aspirin therapy with HBV-related HCC,” the investigators wrote.
They screened 204,507 patients with HBV included in the Taiwanese National Health Insurance Research Database (NHIRD) between 1997 and 2012, first excluding any with confounding conditions, such as hepatitis C infection or alcoholic liver disease. Next, 2,123 patients were identified who had taken aspirin for 90 days or longer. Finally, these cases were randomly matched with 8,492 control patients with HBV who had never received antiplatelet therapy. The main measured outcome was diagnosis with HCC. Patients were followed until this diagnosis was made, death occurred, or the end of the study period.
Analysis showed that most patients were male (72.4%) and took aspirin for about 4 years, usually prescribed for cardiovascular disease risk factors. Almost all patients in the treatment group (98%) received an aspirin dose of 100 mg or less.
After 5 years, the cumulative incidence of HCC in the aspirin group was 5.20% versus 7.87% in the control group (P less than .001). Multivariable analysis revealed that daily aspirin was associated with a significant risk reduction of 29% (HR 0.71; P less than .001), as were nucleos(t)ide analogues and statins, which lowered risk by 46% and 38%, respectively. In contrast, risk increased with older age at the rate of 1% per year, male sex carried an additional risk of 75%, and liver cirrhosis was associated with a 2.89-fold risk increase.
“In the present study, we report that daily aspirin therapy was associated with a reduced incidence of HCC in patients with [chronic hepatitis B],” the investigators wrote. “Our findings may be of help in future efforts to further improve the chemoprevention of HBV-related HCC, and a proof-of-concept study is thus warranted.”
The investigators described several mechanisms that may have contribute to the possible risk reduction provided by aspirin. For one, aspirin inhibits platelet activation, which is associated with development of HBV-related liver disease. Additional benefit may come from induction of HCC cell apoptosis, control of tumor growth, reduced liver fibrosis, and increased liver regeneration, all of which have been associated with aspirin in rodent models.
“Hepatitis B virus–related HCC is generally a consequence of chronic inflammation due to hepatitis, fibrosis, dysplasia, and tumor growth,” the investigators wrote, suggesting that aspirin-related reductions in inflammation could also explain reduced neoplastic activity.
To assess for increased risk of peptic ulcers secondary to aspirin, the investigators performed a subanalysis of peptic ulcer bleeding. These results showed that rates of peptic ulcer bleeding, at around 5%-6%, were similar between the aspirin group and the control group. Among other variables, cirrhosis didn’t significantly affect rates of peptic ulcer bleeding, and aspirin users had similar rates of peptic ulcer bleeding regardless of HBV status. Because of the study design, however, the investigators cautioned that these analyses could underestimate ulcer risk because patients who could not tolerate aspirin for at least 90 days were excluded from the study.
Although statins stood out as another possible risk reducer, the investigators noted that “randomized clinical trials are required to confirm the chemopreventive effect of statins.”
Similarly, the investigators suggested that a prospective trial is needed before aspirin can be adopted as an HCC preventive.

Surge of gabapentinoids for pain lacks supporting evidence
Many clinicians are prescribing the gabapentinoid drugs pregabalin (Lyrica) and gabapentin (Neurontin) for off-label treatment of pain, despite a lack of supporting data or approval from the Food and Drug Administration, according to investigators.
Over the past 15 years, use of gabapentinoids has tripled, a level of growth that cannot be explained by prescriptions for approved indications, reported coauthors Christopher W. Goodman, MD, and Allan S. Brett, MD, of the University of South Carolina, Columbia. Instead, clinicians are turning to gabapentinoids, partly as an option to substitute for opioids, which now have greater prescribing restrictions as a result of the current opioid crisis.
Although clinicians may cite guidelines that support off-label use of gabapentinoids for pain, the investigators warned that many of these recommendations stand on shaky ground.
“Clinicians who prescribe gabapentinoids off-label for pain should be aware of the limited evidence and should acknowledge to patients that potential benefits are uncertain for most off-label uses,” the investigators wrote in a clinical review published online March 25 in JAMA Internal Medicine.
The investigators narrowed down 677 publications to 84 papers describing the use of gabapentinoids for outpatient noncancer pain syndromes for which they are not FDA approved; 54 for gabapentin and 30 for pregabalin. In the domain of analgesia, both agents are currently FDA-approved for postherpetic neuralgia, while pregabalin is additionally approved for pain associated with fibromyalgia and neuropathic pain from diabetic neuropathy and spinal cord injury. Indications in reviewed studies ranged broadly, from conditions somewhat related to those currently approved, such as unspecified neuropathy, to dissimilar conditions, such as chronic pancreatitis and burn injury.
The investigators summarized findings from randomized clinical trials while using case studies to illustrate potential problems with off-label use. In addition, they reviewed the history of gabapentinoids and sources of recommendations for off-label use, such as guidelines and previous review articles.
Six major findings were reported: (1) evidence supporting gabapentin for diabetic neuropathy pain is “mixed at best”; (2) evidence supporting gabapentin for nondiabetic neuropathies is very limited; (3) evidence does not support gabapentinoids for radiculopathy or low back pain; (4) gabapentin has minimal benefit for fibromyalgia pain, based on minimal evidence; (5) evidence does not support gabapentinoids for acute herpes zoster pain; and (6) in almost all studies for other painful indications, gabapentinoids were ineffective or “associated with small analgesic effects that were statistically significant but of questionable clinical importance.”
Case studies complemented this overview, highlighting related clinical dilemmas that the investigators encounter “repeatedly” during inpatient and outpatient care. Along with off-label use, such as gabapentinoid prescriptions for acute sciatica, the investigators reported cases in which neuropathy was diagnosed in place of nonspecific lower body pain to facilitate gabapentin prescription. They also described apparent disregard for risks of polypharmacy in prescriptions for elderly patients and rote use of gabapentinoids in patients with diabetic neuropathy who did not have sufficient discomfort to warrant prescription.
The investigators also cited a number of problems with the language of reviews and guidelines involving gabapentinoids.
“The wording in many guidelines and review articles reinforces an inflated view of gabapentinoid effectiveness or fails to distinguish carefully between evidence-based and non–evidence-based recommendations,” they wrote, adding that clinicians may have misconceptions about neuropathic pain. “One unintended effect of the broad definition [of neuropathic pain] might be to create a mistaken perception that an effective drug for one type of neuropathic pain is effective for all neuropathic pain, regardless of underlying etiology or mechanism,” the investigators suggested.
Another facet of prescribing behavior could be explained in economic terms. Pregabalin, sold under the brand name Lyrica, is considerably more expensive than gabapentin; however, the investigators warned that the similarity of these agents does not equate with interchangeability, noting differences in bioavailability and rate of absorption.
“Unfortunately, published direct comparisons between the 2 drugs in double-blind studies of patients with chronic noncancer pain are virtually nonexistent,” the investigators wrote.
In addition to questionable effectiveness of gabapentinoids for off-label chronic noncancer pain syndromes, Dr. Goodman and Dr. Brett noted that the drugs produce a “substantial incidence of dizziness, somnolence, and gait disturbance.”
They also described a new trend of gabapentinoid abuse and diversion, which may not be surprising, considering that gabapentinoids are reported to augment opioid-induced euphoria.
“Evidence of misuse of gabapentinoids is accumulating and likely related to the opioid epidemic. A recent review article reported an overall population prevalence of gabapentinoid ‘misuse and abuse’ as high as 1%, with substantially higher prevalence noted among patients with opioid use disorders,” the investigators wrote. “This trend is troubling, particularly because concomitant use of opioids and gabapentinoids is associated with increased odds of opioid-related death. Whether these concerns apply to patients receiving long-term prescribed opioid therapy is unclear.”
In the era of the opioid crisis, the investigators acknowledged that many clinicians have serious concerns about adequately treating chronic noncancer pain.
“Comprehensive management of pain in primary care settings is difficult. It requires time and resources that are frequently unavailable,” the investigators wrote. “Many patients with chronic pain have limited or no access to high-quality pain practices or to nonpharmacologic interventions, such as cognitive behavior therapy.”
The investigators reported no external funding or conflicts of interest.

Many clinicians are prescribing the gabapentinoid drugs pregabalin (Lyrica) and gabapentin (Neurontin) for off-label treatment of pain, despite a lack of supporting data or approval from the Food and Drug Administration, according to investigators.
Over the past 15 years, use of gabapentinoids has tripled, a level of growth that cannot be explained by prescriptions for approved indications, reported coauthors Christopher W. Goodman, MD, and Allan S. Brett, MD, of the University of South Carolina, Columbia. Instead, clinicians are turning to gabapentinoids, partly as an option to substitute for opioids, which now have greater prescribing restrictions as a result of the current opioid crisis.
Although clinicians may cite guidelines that support off-label use of gabapentinoids for pain, the investigators warned that many of these recommendations stand on shaky ground.

Rituximab boosts survival in primary CNS lymphoma
For patients with primary central nervous system lymphoma (PCNSL), adding rituximab to combination high-dose methotrexate and temozolomide significantly boosted the 5-year overall survival rate, according to a retrospective study.
The triplet combination could be a safe and effective first-line option for patients with PCNSL, particularly the frail and elderly, who may have issues with toxicity when receiving current standard care, reported lead author Cui Chen, MD, of Sun Yat-Sen University Cancer Center in Guangzhou, China, and his colleagues.
“An increasing number of studies and meta‐analyses have investigated the effect of rituximab in PCNSL, indicating that rituximab can robustly enhance the response rate and possibly improve survival,” the investigators wrote in Cancer Medicine. “However, data regarding the addition of rituximab to [methotrexate and temozolomide] for PCNSL are limited, and no study has directly compared the efficacy of [rituximab/high-dose methotrexate/temozolomide] to that of [high-dose methotrexate/temozolomide].”
The study involved 62 patients with untreated PCNSL who were diagnosed between 2005 and 2015. Out of the 62 patients, 32 received rituximab/high-dose methotrexate/temozolomide (RMT) and 30 received high-dose methotrexate/temozolomide (MT). Patients received up to eight cycles of therapy, with discontinuation upon disease progression or toxicity.
The results showed that patients treated with RMT had significantly better outcomes than those who received MT, first marked by objective response rates, which were 93.7% for RMT and 69.0% for MT.
Survival rates also showed the advantage of rituximab. For the RMT group, 2-year and 5-year progression-free survival rates were 81.3% and 53.3%, respectively, compared with 46.5% and 29.1% for patients receiving MT.
Most importantly, rituximab boosted overall survival to a significant and notable extent, with higher rates at 2 years (82.3% vs. 65.7%) and 5 years (82.3% vs. 50.0%).
Efficacy did not diminish safety, as no significant differences in toxicity were found between treatment types. The most common grade 3-4 toxicities were hematologic; most commonly, this entailed neutropenia, which occurred in about one-quarter of patients.
“Given its outstanding efficacy and favorable toxicity, we consider RMT to be a feasible and safe therapeutic approach as a first‐line treatment for PCNSL. Moreover, RMT is an ideal regimen for elderly patients and frail populations who may not tolerate [whole‐brain radiation therapy] or [autologous stem‐cell transplantation],” the researchers wrote.
The study was funded by the Natural Science Foundation of Guangdong Province. The researchers reported having no conflicts of interest.

Cirrhosis model predicts decompensation across diverse populations
A prognostic model that uses serum albumin-bilirubin (ALBI) and Fibrosis-4 (FIB-4) scores can identify patients with cirrhosis who are at high risk of liver decompensation, according to investigators.
During validation testing, the scoring system performed well among European and Middle Eastern patients, which supports prognostic value across diverse populations, reported lead author Neil Guha, MRCP, PhD, of the University of Nottingham (U.K.) and his colleagues, who suggested that the scoring system could fix an important practice gap.
“Identification of patients [with chronic liver disease] that need intensive monitoring and timely intervention is challenging,” the investigators wrote in Clinical Gastroenterology and Hepatology. “Robust prognostic tools using simple laboratory variables, with potential for implementation in nonspecialist settings and across different health care systems, have significant appeal.”
Although existing scoring systems have been used for decades, they have clear limitations, the investigators noted, referring to predictive ability that may be too little, too late.
“[T]hese scoring systems provide value after synthetic liver function has become significantly deranged and provide only short-term prognostic value,” the investigators wrote. “Presently, there are no scores, performed in routine clinical practice, that provide robust prognostic stratification within early, compensated cirrhosis over the medium/long term.”
To fulfill this need, the investigators developed and validated a prognostic model that incorporates data from the ALBI and FIB-4 scoring systems because these tests measure both fibrosis and function. The development phase involved 145 patients with compensated cirrhosis from Nottingham. Almost half of the cohort had liver disease because of alcohol (44.8%), while about one out of three patients had nonalcoholic fatty liver disease (29.7%). After investigators collected baseline clinical features and scores, patients were followed for a median of 4.59 years, during which time decompensation events were recorded (ascites, variceal bleeding, and encephalopathy). Decompensation occurred in about one out of five patients (19.3%) in the U.K. group, with ascites being the most common (71.4%). Using these findings, the investigators created the prognostic model, which classified patients as having either low or high risk of decompensation. In the development cohort, patients with high risk scores had a hazard ratio for decompensation of 7.10.
In the second part of the study, the investigators validated their model with two clinically distinct groups in Dublin, Ireland (prospective; n = 141), and Menoufia, Egypt (retrospective; n = 93).
In the Dublin cohort, the most common etiologies were alcohol (39.7%) and hepatitis C (29.8%). Over a maximum observational period of 6.4 years, the decompensation rate was lower than the development group, at 12.1%. Types of decompensation also differed, with variceal bleeding being the most common (47.1%). Patients with high risk scores had a higher HR for decompensation than the U.K. cohort, at 12.54.
In the Egypt group, the most common causes of liver disease were nonalcoholic fatty liver disease (47.3%) and hepatitis C (34.4%). The maximum follow-up period was 10.6 years, during which time 38.7% of patients experienced decompensation, with ascites being the most common form (57.1%). The HR of 5.10 was the lowest of all cohorts.
The investigators noted that the cohorts represented unique patient populations with different etiological patterns. “This provides reassurance that the model has generalizability for stratifying liver disease at an international level,” the investigators wrote, suggesting that ALBI and FIB-4 can be used in low-resource and community settings.
“A frequently leveled criticism of algorithms such as ALBI-FIB-4 is that they are too complicated to be applied routinely in the clinical setting,” the investigators wrote. “To overcome this problem we developed a simple online calculator which can be accessed using the following link: https://jscalc.io/calc/gdEJj89Wz5PirkSL.”
“We have shown that routinely available laboratory variables, combined in a novel algorithm, ALBI-FIB-4, can stratify patients with cirrhosis for future risk of liver decompensation,” the investigators concluded. “The ability to do this in the context of early, compensated cirrhosis with preserved liver synthetic function whilst also predicting long-term clinical outcomes has clinical utility for international health care systems.”
The study was funded by National Institute for Health Research (NIHR) Nottingham Digestive Diseases Biomedical Research Centre based at Nottingham University Hospitals NHS Trust and the University of Nottingham. The investigators declared no conflicts of interest.

To fulfill this need, the investigators developed and validated a prognostic model that incorporates data from the ALBI and FIB-4 scoring systems because these tests measure both fibrosis and function. The development phase involved 145 patients with compensated cirrhosis from Nottingham. Almost half of the cohort had liver disease because of alcohol (44.8%), while about one out of three patients had nonalcoholic fatty liver disease (29.7%). After investigators collected baseline clinical features and scores, patients were followed for a median of 4.59 years, during which time decompensation events were recorded (ascites, variceal bleeding, and encephalopathy). Decompensation occurred in about one out of five patients (19.3%) in the U.K. group, with ascites being the most common (71.4%). Using these findings, the investigators created the prognostic model, which classified patients as having either low or high risk of decompensation. In the development cohort, patients with high risk scores had a hazard ratio for decompensation of 7.10.
In the second part of the study, the investigators validated their model with two clinically distinct groups in Dublin, Ireland (prospective; n = 141), and Menoufia, Egypt (retrospective; n = 93).
In the Dublin cohort, the most common etiologies were alcohol (39.7%) and hepatitis C (29.8%). Over a maximum observational period of 6.4 years, the decompensation rate was lower than the development group, at 12.1%. Types of decompensation also differed, with variceal bleeding being the most common (47.1%). Patients with high risk scores had a higher HR for decompensation than the U.K. cohort, at 12.54.
In the Egypt group, the most common causes of liver disease were nonalcoholic fatty liver disease (47.3%) and hepatitis C (34.4%). The maximum follow-up period was 10.6 years, during which time 38.7% of patients experienced decompensation, with ascites being the most common form (57.1%). The HR of 5.10 was the lowest of all cohorts.
The investigators noted that the cohorts represented unique patient populations with different etiological patterns. “This provides reassurance that the model has generalizability for stratifying liver disease at an international level,” the investigators wrote, suggesting that ALBI and FIB-4 can be used in low-resource and community settings.
“A frequently leveled criticism of algorithms such as ALBI-FIB-4 is that they are too complicated to be applied routinely in the clinical setting,” the investigators wrote. “To overcome this problem we developed a simple online calculator which can be accessed using the following link: https://jscalc.io/calc/gdEJj89Wz5PirkSL.”
“We have shown that routinely available laboratory variables, combined in a novel algorithm, ALBI-FIB-4, can stratify patients with cirrhosis for future risk of liver decompensation,” the investigators concluded. “The ability to do this in the context of early, compensated cirrhosis with preserved liver synthetic function whilst also predicting long-term clinical outcomes has clinical utility for international health care systems.”
The study was funded by National Institute for Health Research (NIHR) Nottingham Digestive Diseases Biomedical Research Centre based at Nottingham University Hospitals NHS Trust and the University of Nottingham. The investigators declared no conflicts of interest.

Worse survival seen among black patients with MCL
Black non-Hispanic patients with mantle cell lymphoma (MCL) have a lower rate of 5-year overall survival, compared with white non-Hispanic and Hispanic patients, according to a retrospective analysis of more than 18,000 cases.
However, black patients were also most likely to receive treatment at an academic center, which was an independent predictor of better survival, reported Nikesh N. Shah, MD, of Emory University, Atlanta, and his colleagues. This finding suggests that even academic centers still need to focus on overcoming demographic disparities.
“Racial and socioeconomic differences have been reported in many malignancies and certain lymphomas; however, few studies report on disparities in MCL,” the investigators wrote in Clinical Lymphoma, Myeloma & Leukemia. “To our knowledge this is the first such study to assess racial and socioeconomic disparities in this disease.”
The investigators reviewed 18,120 patients with MCL diagnosed between 2004 and 2013; data were drawn from the National Cancer Database. The primary endpoint was overall survival from the time of diagnosis, with analyses conducted to assess various associations with race/ethnicity, facility type, clinical/tumor characteristics, cancer stage, insurance type, and other factors.
Results showed that Hispanic patients had the highest rate of overall survival, at 55.8%, followed by white patients, at 50.1%. Trailing behind these groups were black patients (46.8%) and patients of other races/ethnicities (46.0%).
Along with survival disparities, race/ethnicity was tied to certain clinical and treatment characteristics. Compared with white patients, black patients were more likely to experience B symptoms (28% vs. 25%) and have Medicaid or lack insurance (15% vs. 5%). Black and Hispanic patients were also less likely than white non-Hispanic patients to receive stem cell transplant (13% vs. 10% vs. 10%).
Although black patients were more likely than white patients to receive treatment at an academic center (51% vs. 38%), a factor independently associated with best survival among center types, whatever advantage provided apparently did not exceed disadvantages associated with race.
“We report inferior overall survival in black patients after accounting for socioeconomic status, as seen in other malignancies,” the investigators wrote. “Surprisingly, these patients were more likely to be treated at academic centers, which independently showed improved overall survival in multivariable analysis that controlled for age, disease stage, insurance status, and other socioeconomic factors.”
The researchers cited a number of steps that could help close the survival gap, including providing more comprehensive supportive care between physician visits and enrollment of patients from diverse racial background on clinical trials.
The study was funded by the National Institutes of Health. The researchers reported having no conflicts of interest.

Infant survival rate after HCT remains flat
High rates of relapse and toxicities among infants who undergo allogeneic hematopoietic cell transplant (allo-HCT) contribute to survival rates that have remained largely unchanged from 2000-2014, based on a retrospective study of almost 2,500 cases.
Although survival rates improved from 2000 to 2004 among children aged 1 and younger who underwent allo-HCT for nonmalignant conditions, rates plateaued thereafter, reported lead author Suhag H. Parikh, MD, of Duke University Medical Center in Durham, North Carolina, and his colleagues. Still more disappointing, survival rates for infants with malignant conditions remained relatively flat throughout the 15-year study period.
For adult patients, allo-HCT survival rates have improved over time, but data for infants are rare. This is a concerning blind spot because infants are a particularly vulnerable population in the transplant setting.
“Infants may be at higher risk for toxicities than adults,” the investigators wrote in JAMA Pediatrics. “Although children are considered to have better tolerance to high-intensity or myeloablative conditioning regimens and perhaps better immune reconstitution owing to a functional thymus, infants may be at higher risk of transplant-associated complications.”
The present study involved 2,498 infants,1 year old or younger (median age 7 months), who underwent allo-HCT for malignant or nonmalignant conditions between 2000 and 2014. Information was drawn from The Center for International Blood and Marrow Transplant Research (CIBMTR), which consists of data from more than 450 transplant centers across the world.
The investigators assessed overall survival trends among infants undergoing allo-HCT; in addition, they analyzed factors contributing to mortality and rates of two major organ toxicities: sinusoidal obstruction syndrome and idiopathic pneumonia syndrome. Cases were divided into 2 cohorts: malignant and nonmalignant. Time-analysis was divided into three periods: 2000-2004, 2005-2009, and 2010-2014.
Overall, the results were disheartening. Survival trends were generally flat during the 15-year study period, and some outcomes actually worsened over time. As a small highlight, infants with nonmalignant disease had improved survival when comparing the second and third time period with the first time period (HR, 0.77; P = .007); however, this trend fell flat after 2004. Three-year overall survival rates for infants with nonmalignant disease from least recent to most recent time period, were 65.0%, 72.0%, and 74.0%.
Survival was poorer with malignant conditions, with 3-year overall survival rates of 54.8%, 64.6%, and 58.9% from least recent to most recent time period. This trend was associated with a worsening relapse rate, which increased from 19% to 36% from 2000 to 2014.
Also, toxicities were relatively common. Sinusoidal obstruction syndrome occurred in 32% of infants with malignant disease and in 13% with nonmalignant conditions. The rate of interstitial pneumonia syndrome at 100 days post-transplant was 5% across all patients.
Optimal supportive care and donor/graft selection might improve outcomes, as could reduced-intensity/nonmyeloablative conditioning regimens rather than total body irradiation, according to the researchers.
Changes in practice for disease subgroups may be warranted, based on the improved survival rate seen for infants with nonmalignant disease, which was mostly driven by better outcomes in patients with severe combined immunodeficiency, a disease subgroup that has had newborn-screening programs since 2008. Judging by the trends, such programs are truly making a difference, the researchers wrote.
The study was funded by the National Cancer Institute (NCI); the National Heart, Lung and Blood Institute (NHLBI); Health Resources and Services Administration; the Office of Naval Research; and a number of private pharmaceutical companies. The investigators reported financial relationships with Sangamo Therapeutics, Mallinckrodt, Takeda, Jazz, and others.

MitraClip improves survival and health status for at least 2 years
, based on results from a substudy of the COAPT trial.
Significant improvements seen at 1 month in the TMVr group had waned only slightly by the 2-year time point, reported lead author Suzanne V. Arnold, MD, of Saint Luke’s Mid America Heart Institute and University of Missouri–Kansas City, who presented the findings at the annual meeting of the American College of Cardiology. The study was simultaneously published in the Journal of the American College of Cardiology.
“Considering the previously reported benefits of TMVr on survival and heart failure hospitalization, these health status findings further support the device as a valuable treatment option for heart failure patients with severe secondary mitral regurgitation who remain symptomatic despite maximally-tolerated guideline-directed medical therapy,” Dr. Arnold and her colleagues concluded.
Primary findings from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial showed that TMVr reduced hospitalizations due to heart failure and all-cause mortality over 2 years, leading the Food and Drug Administration to grant an extended indication to MitraClip. With the present substudy, the investigators sought to learn more about impacts of TMVr on overall health.
“Beyond prolonging survival and reducing hospitalizations, improving patients’ health status (i.e., symptoms, functional status, quality of life) is a key treatment goal of TMVr,” the investigators wrote. “In fact, among older patients with comorbidities and high symptom burden, health status improvement may be of greater importance to patients than improved survival.”
To measure these outcomes, the investigators employed the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the SF-36 health status survey, which they administered to 302 patients in the TMVr group and 312 patients in the standard care group. The primary endpoint was the KCCQ overall summary score (KCCQ-OS), which ranges from 0 to 100, with higher scores indicating better health status.
Across all patients, the average baseline KCCQ-OS score was 52.4 ± 23.0. After 1 month, the average KCCQ-OS score rose 2.1 points in the standard care group, while the TMVr group saw a 16.9-point increase, most heavily through the questionnaire’s quality of life domain. These figures translate to a mean between-group difference of 15.9 points, a value that decreased only slightly after 2 years, to 12.8 points. Further suggesting that TMVr had beneficial and lasting effects, a significantly greater percentage of patients in the TMVr group than in the standard care group were alive with a moderately large health improvement after 2 years (36.4% vs 16.6%; P less than .001).
The study was funded by Abbott Vascular. Several of the investigators reported financial relationships with Abbott as well as Novartis, Bayer, V-wave, Corvia, and others.

Ovarian cancer survivors carry burden of severe long-term fatigue
Women who have survived epithelial ovarian cancer (EOC) more often report severe long-term fatigue than healthy women, according to a case-control study involving more than 600 individuals.
Ovarian cancer survivors had a higher rate of sleep disturbance, neuropathy, and depression, reported lead author Florence Joly, MD, of Centre François Baclesse in Caen, France, and her colleagues. These factors likely contribute to severe long-term fatigue; a condition that has been minimally researched in EOC survivors.
“Long-term fatigue has been described as one of the most common and distressing adverse effects of cancer and its treatment,” the investigators wrote in Annals of Oncology. However, “Little is known about the prevalence of long-term fatigue in EOC survivors several years after treatment in comparison with age-matched healthy women.”
The study involved 318 EOC survivors who had not relapsed for at least 3 years, and 318 age-matched, healthy women. Survivors were 63 years old, on average, and split almost evenly between cases of early and advanced disease (50% stage I/II vs. 48% stage III/IV). Almost all patients had received platinum/taxane chemotherapy (99%). Average follow-up was 6 years.
Participants self-reported through questionnaires about physical activity (International Physical Activity Questionnaire), sleep disturbance ( Insomnia Severity Index), anxiety/depression (Hospital Anxiety and Depression Scale), neuropathy (Functional Assessment of Cancer Therapy-Taxane Neurotoxicity [FACT-Ntx]), quality of life ( Functional Assessment of Cancer Therapy-General/Ovarian), and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Severe long-term fatigue was defined as a FACIT-F score of less than 37. Analysis was performed to find rates of severe long-term fatigue and contributing factors.
Although sociodemographic measures and global quality of life were similar between groups, 26% of EOC survivors reported severe long-term fatigue, compared with 13% of healthy women (P = .0004). Multivariable analysis revealed that three main factors contributed to this trend; worse neuropathy scores (FACT-Ntx 35 vs. 39), higher rates of depression (22% vs. 13%), and lower sleep quality (63% vs. 47%).
“These results highlight the need for continuous screening of sleep disturbance and depression as soon as the diagnosis of EOC is made, and for sleep disturbance interventions in EOC survivors,” the investigators wrote. “As pharmacological treatment seems to have limited efficacy, behavioral interventions should be offered to improve sleep quality and/or depressive symptoms.”
“Fewer than 20% of our EOC survivors and controls exercised regularly, a finding consistent with a recent study conducted in long-term EOC survivors,” the investigators noted. “Personalized clinical exercise programs were effective in improving fatigue and depression in a heterogeneous population of cancer survivors, so they should be promoted in EOC survivors [too].”
The study was funded by Fondation de France. The investigators disclosed financial relationships with AstraZeneca, Janssen, Sanofi, Novartis, and others.

Women who have survived epithelial ovarian cancer (EOC) more often report severe long-term fatigue than healthy women, according to a case-control study involving more than 600 individuals.
Ovarian cancer survivors had a higher rate of sleep disturbance, neuropathy, and depression, reported lead author Florence Joly, MD, of Centre François Baclesse in Caen, France, and her colleagues. These factors likely contribute to severe long-term fatigue; a condition that has been minimally researched in EOC survivors.
“Long-term fatigue has been described as one of the most common and distressing adverse effects of cancer and its treatment,” the investigators wrote in Annals of Oncology. However, “Little is known about the prevalence of long-term fatigue in EOC survivors several years after treatment in comparison with age-matched healthy women.”
The study involved 318 EOC survivors who had not relapsed for at least 3 years, and 318 age-matched, healthy women. Survivors were 63 years old, on average, and split almost evenly between cases of early and advanced disease (50% stage I/II vs. 48% stage III/IV). Almost all patients had received platinum/taxane chemotherapy (99%). Average follow-up was 6 years.
Participants self-reported through questionnaires about physical activity (International Physical Activity Questionnaire), sleep disturbance ( Insomnia Severity Index), anxiety/depression (Hospital Anxiety and Depression Scale), neuropathy (Functional Assessment of Cancer Therapy-Taxane Neurotoxicity [FACT-Ntx]), quality of life ( Functional Assessment of Cancer Therapy-General/Ovarian), and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F).
