Tisagenlecleucel has the potential to be cost-effective for pediatric B-cell acute lymphoblastic leukemia (B-ALL) patients in the United States, according to researchers.

The group found evidence to suggest the chimeric antigen receptor (CAR) T-cell therapy—which has a list price of $475,000—may prove cost-effective if long-term survival benefits are realized.

An analysis indicated that the incremental cost-effectiveness ratio for tisagenlecleucel compared to clofarabine ranged from $37,000 to $78,000 per quality-adjusted life year (QALY) gained.

Melanie D. Whittington, PhD, of the University of Colorado at Denver, Aurora, and her colleagues described this work in JAMA Pediatrics.

For this study, the researchers used a decision analytic model that extrapolated the evidence from clinical trials over a patient’s lifetime to assess life-years gained, QALYs gained, and incremental costs per life-year and QALY gained. The researchers compared tisagenlecleucel to the antineoplastic agent clofarabine.

While tisagenlecleucel has a list price of $475,000, researchers discounted the price by 3% and added several additional costs, such as hospital administration, pretreatment, and potential adverse events, to get to a total discounted cost of about $667,000.

The team estimated that 42.6% of B-ALL patients would be long-term survivors with tisagenlecleucel, 10.34 life-years would be gained, and 9.28 QALYs would be gained.

In comparison, clofarabine had a total discounted cost of approximately $337,000, which included an initial discounted price of $164,000 plus additional treatment and administrative costs.

With clofarabine, 10.8% of B-ALL patients were long-term survivors, 2.43 life-years were gained, and 2.10 QALYs were gained in the model.

Overall, the mean incremental cost-effectiveness ratio was about $46,000 per QALY gained in this base-case model.

In analyses of different scenarios, such as a deeper discount, a different treatment start, or a different calculation of future treatment costs, the cost-effectiveness ratio varied from $37,000 to $78,000 per QALY gained.

The researchers noted that clinical trial evidence for tisagenlecleucel came from single-arm trials, which made the selection of a comparator challenging. Clofarabine was chosen because it had the most similar baseline population characteristics, but the researchers acknowledged that blinatumomab is also frequently used as a treatment for these patients.

“We suspect that tisagenlecleucel would remain cost-effective compared with blinatumomab,” the researchers wrote in JAMA Pediatrics. “A study conducted by other researchers found the incremental cost-effectiveness ratio of tisagenlecleucel versus blinatumomab was similar to the incremental cost-effectiveness ratio of tisagenlecleucel versus clofarabine [i.e., $3,000 more per QALY].”

The researchers suggested that uncertainties in the evidence should be considered as payers are negotiating coverage and payment for tisagenlecleucel.

Cancer treatments that prolong progression-free survival (PFS) may not improve health-related quality of life (HRQOL), researchers reported in JAMA Internal Medicine.

The researchers failed to find a significant association between PFS and HRQOL in an analysis of cancer clinical trials.

“There are only two reasons to use progression-free survival as a valid endpoint in oncology,” said study author Feng Xie, PhD, of McMaster University in Hamilton, Ontario, Canada.

“One is that it is a valid surrogate marker for overall survival. The second is the assumption that patients who live longer without disease progression will have better health-related quality of life, even without longer survival.”

“Given the increased use of progression-free survival as the primary outcome in new oncology drug trials, and uncertainty of overall survival, it remains possible that patients are receiving toxic and/or expensive treatments without experiencing important benefit.”

With this in mind, Dr. Xie and his colleagues conducted a review and meta-analysis of 52 articles reporting on 38 randomized clinical trials. The trials included 13,979 patients with 12 types of cancer, including 1 trial of patients with multiple myeloma.

The median follow-up in these trials ranged from 10.5 months to 66.0 months.

The median PFS of patients who received the trial interventions ranged from 1.8 months to 33.7 months.

For 28 of the trials (74%), patients who received the trial intervention had better PFS than patients who received the comparator. Overall, the mean difference in median PFS between the intervention and comparator arms was 1.91 months.

HRQOL was measured with 6 different instruments* across the trials, and the types of HRQOL measured varied. Thirty trials included global HRQOL, 20 included physical, and 13 included emotional HRQOL. The duration of reported or measured HRQOL ranged from 1 month to 34 months.

Improved global HRQOL was reported in 53% of trials (16/30), improved physical HRQOL was reported in 55% (11/20), and improved emotional HRQOL was reported in 62% (8/13). The mean difference in change of HRQOL adjusted to per-month values was −0.39 for global, 0.26 for physical, and 1.08 for emotional HRQOL.

The slope of the association between the difference in median PFS and the difference in HRQOL change was:

• 0.12 (95% confidence interval [CI], −0.27 to 0.52) for global HRQOL
• −0.20 (95% CI,−0.62 to 0.23) for physical HRQOL
• 0.78 (95% CI, −0.05 to 1.60) for emotional HRQOL.

Dr. Xie and his colleagues said these results suggest there is no significant association between PFS and HRQOL, so interventions prolonging PFS may not improve HRQOL.

“Therefore, to ensure patients are truly obtaining important benefit from cancer therapies, clinical trial investigators should measure health-related quality of life directly and accurately, ensuring adequate duration and follow-up, and publish it,” Dr. Xie said.

He also argued for the need to “revisit this issue of using surrogate outcomes to measure the safety and efficacy of new oncology drugs.”

Dr. Xie and his colleagues did not report any conflicts of interest. One study author (Marcin Waligora, PhD) reported funding from the National Science Centre in Poland.

Immunization with two synthetic consensus constructs of hepatitis C virus (HCV) glycoproteins was found to elicit narrow, but not widely effective, virus-neutralizing antibodies in guinea pigs, according to the results of a model study published in the journal Antiviral Research.

Courtesy NIH

Researchers created two novel synthetic E2 glycoprotein immunogens (NotC1 and NotC2) using consensus nucleotide sequences deduced from samples of circulating genotype 1 HCV strains, according to Alexander W. Tarr, PhD, of the Nottingham (England) University Hospitals NHS Trust, and his colleagues.

Expression of these constructs in Drosophila melanogaster cells resulted in high yields of correctly folded, monomeric E2 proteins, which were used to immunize guinea pigs. Both proteins generated antibodies capable of neutralizing the H77 strain of HCV, although NotC1 elicited antibodies that were more potent at neutralizing virus entry. The two sets of glycoprotein-induced antibodies neutralized some HCV strains representing genotype 1, but not those strains representing genotype 2 or genotype 3.

“The broader objective of eliciting antibodies that neutralize patient strains representing multiple genotypes will require further refinement of immunization protocols. A vaccine construct comprising the consensus of a minimal CD81 binding domain might be able to focus the antibody response to conserved epitopes on E2. Additionally, boosting immunized animals with glycoproteins representing different strains might be required to focus the antibody response on to conserved conformational epitopes,” the researchers concluded.

The research was funded by the Medical Research Council, the NIHR Nottingham Biomedical Research Centre, and the European Union. Disclosures were not reported.

HCV strains evolve differently in HIV-coinfected individuals, according to the results of a database analysis of HCV genetic sequences from patients monoinfected with HCV and those who were coinfected with HIV. The study compared results from 112 coinfected persons (CIPs) and 176 monoinfected persons (MIPs), according to the report published in the journal Infection, Genetics, and Evolution.

Gio_tto/Thinkstock

Genetic differences between intrahost variants of the HCV hypervariable region 1 (HVR1) were sampled from CIPs and MIPs, and the nucleotide sequences of intrahost HCV HVR1 variants (n = 28,622) obtained were represented using 148 physical-chemical (PhyChem) indexes of DNA nucleotide dimers. Changes of the intrahost HCV population were detected by measuring coevolution among the HVR1 site using new PhyChem properties extracted from the next-generation sequencing of HVR1 data. Small but statistically significant variances in seven of the PhyChem indexes, measured using these intrahost HVR1 variants, was shown to be strongly associated with CIPs and MIPs (P less than .0001).

“The computational models built using these new markers provide novel opportunities for development of cybermolecular diagnostics,” wrote James Lara, PhD, and his colleagues at the Centers for Disease Control and Prevention.

All HVR1 sequences used (n = 28,622) shared only 6,782 profiles of the selected calculated dinucleotide-based auto covariances of the seven PhyChem indexes. The vast majority (98%-99%) of these profiles were found to be specific to CIPs or MIPs, indicating that coevolution among HVR1 sites reflects HCV adaptation to HIV among coinfected individuals, according to the authors.

Because of the common occurrence of HIV-coinfection in high-risk groups, “HCV strains circulating in high-risk groups need to be carefully monitored for the identification of potentially new traits of clinical and public health relevance,” Dr. Lara and his colleagues concluded.

The authors reported having no conflicts of interest.

MUNICH – Olaparib maintenance therapy significantly reduces risk of disease progression or death in women with BRCA-mutated advanced ovarian cancer who respond to chemotherapy, according to results from the SOLO-1 trial.

Will Pass/MDedge News

The benefit from olaparib was compelling; compared with placebo, more than twice the number of women were alive and without disease progression after 3 years.

Current guidelines recommend olaparib for relapsed ovarian cancer, but the SOLO-1 results support first-line application, said lead author, Kathleen N. Moore, MD at the European Society for Medical Oncology Congress.

“We believe that the SOLO-1 data really prompts a change in the standard of care for women with advanced ovarian cancer who harbor a BRCA mutation,” said Dr. Moore of the Stephenson Cancer Center at the University of Oklahoma in Oklahoma City.

Olaparib (Lynparza) currently is approved for relapsed ovarian cancer regardless of mutation status, but poor outcomes suggest that this intervention is given too late – many patients relapse, and when they do, most do not survive.

“Although the majority of ... patients have no evidence of disease after [chemotherapy], approximately 70% have a relapse within the subsequent 3 years,” the investigators wrote in an article simultaneously published in the New England Journal of Medicine. “Recurrent ovarian cancer is typically incurable, with most patients receiving multiple additional lines of treatment before ultimately dying from the disease.”

Poly (ADP-ribose) polymerase (PARP) inhibitors, such as olaparib, are well matched for BRCA-mutated tumors; they interfere with DNA repair, thereby exploiting repair deficits conferred by BRCA mutations. One in six women with advanced ovarian cancer exhibits a BRCA mutation, so eligible patients are relatively common.

The phase 3, placebo-controlled SOLO-1 trial involved 391 patients with advanced ovarian cancer who had a complete or partial response to platinum-based chemotherapy. Patients exhibited mutations in BRCA1, BRCA2, or both (BRCA1/BRCA2). After chemotherapy, patients were randomized to receive either olaparib 300 mg twice daily or placebo (in a 2:1 ratio).

The primary endpoint was progression-free survival (PFS) determined by imaging; MRI or CT was performed at baseline and every 3 months for up to 3 years, with 6-month intervals thereafter. Patients who had no disease progression at 2 years halted therapy, whereas patients with disease progression were allowed to continue olaparib if desired.

The 3-year follow-up period (median, 40.7 months) revealed a dramatic benefit from olaparib; the PFS rate was 60% for olaparib, compared with 27% for placebo (P less than .001). This represents a 70% reduction in risk of disease progression or death. Because of the magnitude of prolonged survival, median PFS could not be determined; however, estimates suggest that olaparib adds 3 years without disease progression.

Dr. Moore noted that these benefits were consistent regardless of stage or level of response to chemotherapy (partial vs. complete). “Everyone benefits,” she said. “It really looks like an all subgroup-beneficial regimen.”

Still, questions of long-term benefit remain unanswered. “It’s too early to know what [the extended PFS] means long term,” Dr. Moore said. “We hope that it means we’ve converted a larger fraction of patients to cure, and that’s what you’re seeing with the flattening of the survival curve, but it took us 3 years just to get to this point, so how long will it take us to comment on overall survival? It’s a good problem to have, but it’s going to remain to be seen.”

As therapy was discontinued at 2 years, and yet patients remained progression free after 3 years, researchers also are left wondering about mechanisms of action. “Has olaparib eradicated all the disease?” asked Jonathan A. Ledermann, MD, member of the ESMO faculty and professor of medical oncology at University College London. “Or is something else happening, such as an immune response that’s taking over when you stop the drug? We don’t know the answer to that, but it’s an intriguing question and one that we need to follow up on.”

Safety data from SOLO-1 were comparable with previous olaparib trials. Overall, olaparib was well tolerated, with 21% of patients experiencing serious adverse events. The most common serious adverse event was neutropenia (7%).

SOLO-1 was sponsored by AstraZeneca and Merck. The authors reported financial affiliations with Clovis, Tesaro, Mateon, Merck, and others.

Hospitalists hearing the constant noise from cardiac telemetry monitoring systems can experience alarm fatigue – a nationwide phenomenon that can lead to an increase in patient deaths.

The American Heart Association reports that fewer than one in four adults survived an in-hospital cardiac arrest in 2013; other studies showed that up to 44% of inpatient cardiac arrests were not detected appropriately, according to the Cleveland Clinic.

Clinicians at the Cleveland Clinic have tried centralized monitoring to address the problem. They’ve established a “mission control” center, where off-site personnel monitor sensors and high-definition cameras and vital signs such as blood pressure, heart rate, and respiration. On-site action is requested when appropriate; unimportant alarms are dismissed.

In August 2016, results from the first 13 months of the Cleveland Clinic program were published in JAMA. They revealed that the monitoring system could help reduce rates of unimportant alarms with no increase in cardiopulmonary arrest events. The centralized unit monitored 99,048 patient orders, and ultimately detected serious problems and accurately notified on-site staff for 79% of 3,243 events, which included a rhythm and/or rate change within 1 hour or less of the event. Accurate notification to on-site hospital staff was more than 84%.

Since then, improvements to the system have continued, according to Cleveland Clinic, and include doubling the number of monitored patients per technician and improved clinical outcomes.

Women with high and low body mass index in the first trimester of their first pregnancies are at an increased risk of developing postpartum depression, a population-based study of more than 600,000 new mothers shows.

monkeybusinessimages/Thinkstock

“Our findings show a U-shaped association between BMI extremes and clinically significant depression after childbirth,” Michael E. Silverman, PhD, and his associates reported in the Journal of Affective Disorders. “Specifically, women in the lowest and highest groups were at a significantly increased risk for developing [postpartum depression].”

Dr. Silverman and his associates used the Swedish Medical Birth Register to identify women who delivered first live singleton infants from 1997 to 2008. They then calculated the risk of postpartum depression in relation to each woman’s BMI and history of depression. Postpartum depression was defined as a clinical depression diagnosis within 1 year after delivery, Dr. Silverman and his associates wrote.

The investigators found that women with low BMI (less than 18.5 kg/m²) were at an increased postpartum depression risk (relative risk [RR], 1.52; 95% confidence interval, 1.30-1.78), as were those with high BMI (greater than 35 kg/m²) (RR, 1.23; 95% CI, 1.04-1.45).

In addition, an important difference was found between women with low and high BMI.

“Women in the highest BMI group were only at an increased risk for [postpartum depression] if they had no history of depression, showing for the first time how [postpartum depression] risk factors associated with BMI are modified by maternal depression history,” said Dr. Silverman of the department of psychiatry at the Icahn School of Medicine at Mount Sinai, New York, and his associates.

The investigators cited several limitations. For example, only first births were analyzed, which suggests that the incidence of postpartum depression might have been underestimated. Another limitation is that the registry might not have captured women with mild depression. Nevertheless, they said, the study has important implications.

“This study represents the largest and most rigorous exploration into a woman’s early pregnancy BMI as a risk factor for [postpartum depression]. Because pregnant women represent a medically captured population,” they wrote, the findings support implementing preventive strategies for postpartum depression and health literacy for high-risk women.

Dr. Silverman and his associates reported having no conflicts of interest. The study was supported by a grant from the National Institutes of Health.

BARCELONA – What would you predict has a greater detrimental effect on adolescent cognitive development: alcohol or cannabis use?

Bruce Jancin/MDedge News

The evidence-based answer may come as a surprise. It certainly did for Patricia Conrod, PhD, who led the large population-based study that addressed the question.

“Generally, we found no effect of alcohol on cognitive development, which was a huge surprise to us. It might be related to the fact that the quantity of alcohol consumption in this young sample just wasn’t high enough to produce significant effects on cognitive development. But, to our surprise, we found rather significant effects of cannabis use on cognitive development,” she said at the annual congress of the European College of Neuropsychopharmacology.

Indeed, cannabis use proved to have detrimental effects on all four cognitive domains assessed in the study: working memory, perceptual reasoning, delayed recall, and inhibitory control, reported Dr. Conrod, professor of psychiatry at the University of Montreal.

Her recently study, published in the American Journal of Psychiatry, included 3,826 seventh-grade students at 31 Montreal-area schools. They constituted 5% of all students entering that grade in the greater Montreal area. Participants were prospectively assessed annually for 4 years regarding their use or nonuse of alcohol or cannabis and also underwent neurocognitive testing on the four domains of interest. The assessments were done on school computers with preservation of student confidentiality. Investigators used a Big Data approach to model the relationship between the extent of substance use and neurocognitive function variables over time.

Abstinent students were the best performers on the neurocognitive testing. Cannabis use, but not alcohol, in a given year was associated with concurrent adverse effects on all four cognitive domains. In addition, cannabis use showed evidence of having a neurotoxic lag effect on inhibitory control and working memory. This took the form of a lasting effect: A student who reported using cannabis 1 year but not the next showed impairment of inhibitory control and working memory during both years. And a student who used cannabis both years was even more impaired in those domains.

Dr. Conrod found the evidence of a neurotoxic effect of cannabis use on inhibitory control to be of particular concern because in earlier studies she established that impaired inhibitory control is a strong independent risk factor for subsequent substance use disorders.

”So what we’re seeing is indeed that early onset substance use is interfering with cognitive development, which now sets us up to be able to answer the question of whether evidence-based prevention protects cognitive development by delaying early onset of substance use. And over the longer term, does that protect young people against addiction?”

Dr. Conrod and her coworkers are now in the process of obtaining answers to those questions in the large ongoing Canadian Institutes of Health Research-funded Co-Venture Trial. This randomized trial involving thousands of adolescent students used the investigators’ Preventure Program, a school-based, personality-targeted intervention for prevention of substance use and abuse.

The Preventure Program involves two 90-minute group sessions of manual-based cognitive-behavioral therapy. Students are invited to participate if they score at least one standard deviation above the school mean on one of four personality traits that have been shown to increase the risk of substance misuse and psychiatric disorders. The four personality traits are sensation seeking, impulsivity, anxiety sensitivity, and hopelessness. Typically, about 45% of students met that threshold, and 85% of those invited to participate in the program volunteered to do so. Students of similar personality type are grouped together for the targeted therapy sessions.

This brief coping skills intervention has been shown in multiple randomized trials around the world to reduce the likelihood of substance use in at-risk adolescents. For example, in an early trial involving 732 high school students in London, participation in the Preventure Program was associated with a 30% reduction in the likelihood of taking up the use of cannabis within the next 2 years, an 80% reduction in the likelihood of taking up cocaine, and a 50% reduction in the use of other drugs (Arch Gen Psychiatry. 2010 Jan;67[1]:85-93).

Participants were prospectively assessed annually for 4 years regarding their use or nonuse of alcohol or cannabis and also underwent neurocognitive testing on the four domains of interest. The assessments were done on school computers with preservation of student confidentiality. Investigators used a Big Data approach to model the relationship between the extent of substance use and neurocognitive function variables over time.

Abstinent students were the best performers on the neurocognitive testing. Cannabis use, but not alcohol, in a given year was associated with concurrent adverse effects on all four cognitive domains. In addition, cannabis use showed evidence of having a neurotoxic lag effect on inhibitory control and working memory. This took the form of a lasting effect: A student who reported using cannabis 1 year but not the next showed impairment of inhibitory control and working memory during both years. And a student who used cannabis both years was even more impaired in those domains.

Dr. Conrod found the evidence of a neurotoxic effect of cannabis use on inhibitory control to be of particular concern because in earlier studies she established that impaired inhibitory control is a strong independent risk factor for subsequent substance use disorders.

”So what we’re seeing is indeed that early onset substance use is interfering with cognitive development, which now sets us up to be able to answer the question of whether evidence-based prevention protects cognitive development by delaying early onset of substance use. And over the longer term, does that protect young people against addiction?”

Dr. Conrod and her coworkers are now in the process of obtaining answers to those questions in the large ongoing Canadian Institutes of Health Research-funded Co-Venture Trial. This randomized trial involving thousands of adolescent students used the investigators’ Preventure Program, a school-based, personality-targeted intervention for prevention of substance use and abuse.

The Preventure Program involves two 90-minute group sessions of manual-based cognitive-behavioral therapy. Students are invited to participate if they score at least one standard deviation above the school mean on one of four personality traits that have been shown to increase the risk of substance misuse and psychiatric disorders. The four personality traits are sensation seeking, impulsivity, anxiety sensitivity, and hopelessness. Typically, about 45% of students met that threshold, and 85% of those invited to participate in the program volunteered to do so. Students of similar personality type are grouped together for the targeted therapy sessions.

This brief coping skills intervention has been shown in multiple randomized trials around the world to reduce the likelihood of substance use in at-risk adolescents. For example, in an early trial involving 732 high school students in London, participation in the Preventure Program was associated with a 30% reduction in the likelihood of taking up the use of cannabis within the next 2 years, an 80% reduction in the likelihood of taking up cocaine, and a 50% reduction in the use of other drugs (Arch Gen Psychiatry. 2010 Jan;67[1]:85-93).

Regular long-term aspirin use may lower the risk of hepatocellular carcinoma (HCC) and ovarian cancer, adding to the growing evidence that aspirin may play a role as a chemopreventive agent, according to two new studies published in JAMA Oncology.

In the first study, led by Tracey G. Simon, MD, of Massachusetts General Hospital, Boston, the authors evaluated the associations between aspirin dose and duration of use and the risk of developing HCC. They conducted a population-based study, with a pooled analysis of two large prospective U.S. cohort studies: the Nurses’ Health Study and the Health Professionals Follow-up Study. The cohort included a total of 133,371 health care professionals who reported long-term data on aspirin use, frequency, dosage, and duration of use.

For the 87,507 female participants, reporting began in 1980, and for the 45,864 men, reporting began in 1986. The mean age for women was 62 years and was 64 years for men at the midpoint of follow-up (1996). Compared with nonaspirin users, those who used aspirin regularly tended to be older, former smokers, and regularly used statins and multivitamins. During the follow-up period, which was more than 26 years, there were 108 incident cases of HCC (65 women, 43 men; 47 with noncirrhotic HCC).

The investigators found that regular aspirin use was associated with a significantly lower HCC risk versus nonregular use (multivariable hazard ratio, 0.51; 95% confidence interval, 0.34-0.77), and estimates were similar for both sexes. Adjustments for regular NSAID use (for example, at least two tablets per week) did not change the data, and results were similar after further adjustment for coffee consumption and adherence to a healthy diet. The benefit also appeared to be dose related, as compared with nonuse, the multivariable-adjusted HR for HCC was 0.87 (95% CI, 0.51-1.48) for up to 1.5 tablets of standard-dose aspirin per week and 0.51 (95% CI, 0.30-0.86) for 1.5-5 tablets per week. The most benefit was for at least five tablets per week (HR, 0.49; 95% CI, 0.28-0.96; P = .006).

“Our findings add to the growing literature suggesting that the chemopreventive effects of aspirin may extend beyond colorectal cancer,” they wrote.

In the second study, Mollie E. Barnard, ScD, of the Harvard School of Public Health, Boston, and her colleagues looked at whether regular aspirin or NSAID use, as well as the patterns of use, were associated with a lower risk of ovarian cancer.

The data used were obtained from 93,664 women in the Nurses’ Health Study (NHS), who were followed up from 1980 to 2014, and 111,834 people in the Nurses’ Health Study II (NHSII), who were followed up from 1989 to 2015. For each type of agent, including aspirin, low-dose aspirin, nonaspirin NSAIDs, and acetaminophen, they evaluated the timing, duration, frequency, and number of tablets that were used. The mean age of participants in the NHS at baseline was 45.9 years and 34.2 years in the NHSII.

There were 1,054 incident cases of epithelial ovarian cancer identified during the study period. The authors did not detect any significant associations between aspirin and ovarian cancer risk when current users and nonusers were compared, regardless of dose (HR, 0.99; 95% CI, 0.83-1.19). But when low-dose (less than or equal to 100 mg) and standard-dose (325 mg) aspirin were analyzed separately, an inverse association for low-dose aspirin (HR, 0.77; 95% CI, 0.61-0.96) was observed. However, there was no association for standard-dose aspirin (HR, 1.17; 95% CI, 0.92-1.49).

In contrast, use of nonaspirin NSAIDs was positively associated with a higher risk of ovarian cancer when compared with nonuse (HR, 1.19; 95% CI, 1.00-1.41), and there were significant positive trends for duration of use (P = .02) and cumulative average tablets per week (P = .03). No clear associations were identified for acetaminophen use.

“Our results also suggest an increased risk of ovarian cancer among long-term, high-quantity users of nonaspirin analgesics, although this finding may reflect unmeasured confounding,” wrote Dr. Barnard and her coauthors. “Further exploration is warranted to evaluate the mechanisms by which heavy use of aspirin, nonaspirin NSAIDs, and acetaminophen may contribute to the development of ovarian cancer and to replicate our findings.”

The ovarian cancer study was supported by awards from the National Institutes of Health. Dr. Barnard was supported by awards from the National Cancer Institute, and her coauthors had no disclosures to report. The HCC study was funded by an infrastructure grant from the Nurses’ Health Study, an infrastructure grant from the Health Professionals Follow-up Study, and NIH grants to several of the authors. Dr. Chan has previously served as a consultant for Bayer on work unrelated to this article. No other disclosures were reported.
