ABSTRACT
Multicancer detection (MCD) tests use a single, easily obtainable biospecimen, such as blood, to screen for more than one cancer concurrently. MCD tests can potentially be used to improve early cancer detection, including cancers that currently lack effective screening methods. However, these tests have unknown and unquantified benefits and harms. MCD tests differ from conventional cancer screening tests in that the organ responsible for a positive test is unknown, and a broad diagnostic workup may be necessary to confirm the location and type of underlying cancer. Among two prospective studies involving greater than 16,000 individuals, MCD tests identified those who had some cancers without currently recommended screening tests, including pancreas, ovary, liver, uterus, small intestine, oropharyngeal, bone, thyroid, and hematologic malignancies, at early stages. Reported MCD test sensitivities range from 27% to 95% but differ by organ and are lower for early stage cancers, for which treatment toxicity would be lowest and the potential for cure might be highest. False reassurance from a negative MCD result may reduce screening adherence, risking a loss in proven public health benefits from standard-of-care screening. Prospective clinical trials are needed to address uncertainties about MCD accuracy to detect different cancers in asymptomatic individuals, whether these tests can detect cancer sufficiently early for effective treatment and mortality reduction, the degree to which these tests may contribute to cancer overdiagnosis and overtreatment, whether MCD tests work equally well across all populations, and the appropriate diagnostic evaluation and follow-up for patients with a positive test.

Cancer prevention encompasses both screening strategies to find cancers early when they are likely to be most treatable and prevention and interception strategies to reduce the risk of developing cancers. Bioconjugates, here defined broadly as materials and molecules that have synthetic and biological components, have roles to play across the cancer-prevention spectrum. In particular, bioconjugates may be developed as affordable, accessible, and effective screening strategies or as novel vaccines and drugs to reduce one's risk of developing cancers. Developmental programs are available for taking novel technologies and evaluating them for clinical use in cancer screening and prevention. While a variety of different challenges exist in implementing cancer-prevention interventions, a thoughtful approach to bioconjugates could improve the delivery and acceptability of the interventions.
ABSTRACT
BACKGROUND: Patient perspectives are fundamental to defining tolerability of investigational anti-neoplastic therapies in clinical trials. Phase I trials present a unique challenge in designing tools for efficiently collecting patient-reported outcomes (PROs) given the difficulty of anticipating adverse events of relevance. However, phase I trials also offer an opportunity for investigators to optimize drug dosing based on tolerability for future larger-scale trials and in eventual clinical practice. Existing tools for comprehensively capturing PROs are generally cumbersome and are not routinely used in phase I trials. METHODS: Here, we describe the creation of a tailored survey based on the National Cancer Institute's PRO-CTCAE for collecting patients' perspectives on symptomatic adverse events in phase I trials in oncology. RESULTS: We describe our stepwise approach to condensing the original 78-symptom library into a modified 30 term core list of symptoms which can be efficiently applied. We further show that our tailored survey aligns with phase I trialists' perspectives on symptoms of relevance. CONCLUSIONS: This tailored survey represents the first PRO tool developed specifically for assessing tolerability in the phase I oncology population. We provide recommendations for future work aimed at integrating this survey into clinical practice.

MOTIVATION: The Division of Cancer Epidemiology and Genetics (DCEG) and the Division of Cancer Prevention (DCP) at the National Cancer Institute (NCI) have recently generated genome-wide association study (GWAS) data for multiple traits in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Genomic Atlas project. The GWAS included 110 000 participants. The dissemination of the genetic association data through a data portal called GWAS Explorer, in a manner that addresses the modern expectations of FAIR reusability by data scientists and engineers, is the main motivation for the development of the open-source JavaScript software development kit (SDK) reported here. RESULTS: The PLCO GWAS Explorer resource relies on a public stateless HTTP application programming interface (API) deployed as the sole backend service for both the landing page's web application and third-party analytical workflows. The core PLCOjs SDK is mapped to each of the API methods, and also to each of the reference graphic visualizations in the GWAS Explorer. A few additional visualization methods extend it. As is the norm with web SDKs, no download or installation is needed and modularization supports targeted code injection for web applications, reactive notebooks (Observable) and node-based web services.

BACKGROUND: Adverse event (AE) reporting in early-phase clinical trials is essential in determining the tolerability of experimental anticancer therapies. The patient-reported outcome version of the CTCAE (PRO-CTCAE) evaluates AE components such as severity and interference in daily life. The aim of this study was to correlate the grade of clinician-reported AEs with patients' reported experience of these toxicities using PRO-CTCAE. METHODS: Patients with advanced solid tumours enrolled on Phase I clinical trials were surveyed using the PRO-CTCAE. Symptomatic AEs were recorded by physicians using the CTCAE. A logistic regression model was used to assess associations between CTCAE grade and PRO responses. RESULTS: Of 219 evaluable patients, 81 experienced a high-grade (3/4) clinician-reported symptom, and of these, only 32 (40%) and 26 (32%) patients concordantly reported these as either severe or very severe, and interfering with daily life either 'quite a bit' or 'very much', respectively. Of the 137 patients who experienced a low-grade (1/2) clinician-reported AE as their worst symptom, 98 (72%) and 118 (86%) patients concordantly reported these as either mild-moderate severity and minimally interfering with daily life, respectively. There was a statistically significant association between clinician-reported AE grade and interference. Interference scores were also associated with dose reductions. CONCLUSION: This is the first study to explore patient-reported severity and interference from symptomatic toxicities and compare clinician grading of the same toxicities. The study provided further evidence to support the added value of the PRO-CTCAE in Phase I oncology trials, which would make AE reporting patient-centred. Further work is needed to determine how this would affect the assessment of tolerability.

Advances in cancer treatments have led to nearly 17 million survivors in the US today. Cardiovascular complications attributed to cancer treatments are the leading cause of morbidity and mortality in cancer survivors. In response, NCI and NHLBI held 2 workshops and issued funding opportunities to strengthen research on cardiotoxicity. A representative portfolio of NIH grants categorizing basic, interventional, and observational projects is presented. Compared with anthracyclines, research on radiation therapy and newer treatments is underrepresented. Multidisciplinary collaborative research that considers the cardiotoxicity stage and optimizes the balance between cardiovascular risk and cancer-treatment benefit might support continued improvements in cancer outcomes.

Several studies have shown that non-adherence to medication use is associated with lower use of preventive services and increased mortality. We aimed to study the relationship between initial adherence to medication use and mortality in the Prostate Cancer Prevention Trial (PCPT). The PCPT randomized men age 55 and over to a finasteride or placebo arm. Duration of treatment was seven years, followed by end-of-study prostate biopsy. Extended follow-up for mortality was performed by linkage to the National Death Index. Non-adherence was defined as taking under 80% of required pills during the first or second 6-month trial period. Proportional hazards models were used to assess the relationship between adherence and all-cause mortality (excluding prostate cancer deaths). Three models were developed as follows: Model I (controlling for demographics and trial arm), Model II (Model I factors plus specific medical conditions), Model III (Model II factors plus lifestyle factors). Of 18,667 men included in the analysis, 3082 (16.5%) were non-adherent. The most common reasons for non-adherence were side effects (33.9%) and forgetting to take pills (22%). Through 5 and 10 years of follow-up, 178 (5.9%) and 483 (15.7%) non-adherent men died versus 581 (3.7%) and 1887 (12.1%) adherent men. Hazard ratios (HRs) at 5 years were 1.62 (95% CI: 1.37-1.91), 1.55 (95% CI: 1.30-1.83) and 1.49 (95% CI: 1.25-1.76) for Models I-III. HRs at ten years were lower but still statistically significant. Non-adherence to taking protocol medications was associated with increased mortality from unrelated conditions.

BACKGROUND: The importance of capturing and reporting health-related quality of life (HRQOL) in clinical trials has been increasingly recognized in the oncology field. As a result, the National Cancer Institute (NCI) began to provide support for correlative HRQOL studies in cancer treatment trials. The current study was conducted to assess the publication rate of HRQOL correlative studies in NCI-supported treatment trials and to identify potential factors positively or negatively associated with publication rates. METHODS: The NCI conducted a retrospective review of existing NCI databases to identify cancer treatment trials that had obtained additional NCI funding for the assessment of HRQOL and to determine the extent to which funded HRQOL studies have been completed and published in a peer-reviewed journal. RESULTS: Of the 108 included trials, 58 (54%) had a parent trial (PT) publication; of these, 36 trials (62%) had a published HRQOL result: 20 as an independent publication and 16 that were included and/or reported in the PT publication. The length of time between trial activation and closure, as well as the specific cancer, appeared to be associated with the publication rates. CONCLUSIONS: The results of the current study demonstrated that approximately 45% of the PT publications were followed by a HRQOL publication within 1 year, to allow the knowledge to be used in patient treatment decision making. The authors believe the current analysis is an important first step toward a better understand of the challenges that researchers face when reporting HRQOL endpoints.

BACKGROUND: To the authors' knowledge, the empiric identification of agents and interventions to mitigate chemotherapy-induced peripheral neuropathy (CIPN) has resulted in only 1 agent that modestly mitigates it and no agents or interventions that prevent its development. This speaks to the need for a mechanistic understanding of CIPN to develop effective interventions. METHODS: To understand the extent to which mechanistic understanding of CIPN is being translated into the development of interventions, the National Cancer Institute conducted a review of the National Institutes of Health (NIH)'s portfolio of investigator-initiated grants, the literature regarding CIPN mechanisms, and the clinical trials listed in the ClinicalTrials.gov database from January 1, 2011, to May 22, 2019. RESULTS: A total of 69 NIH-supported grants and 95 published articles were identified that evaluated mechanistic pathways of 7 different chemotherapy agents that cause CIPN. The review also identified 35 clinical trials that investigated agents or devices with which to treat CIPN. Only 3 trials incorporated a mechanistic rationale to support the choice of the intervention. CONCLUSIONS: To the authors' knowledge, very little of the mechanistic understanding of the development of CIPN is being translated into intervention rationale in clinical trials that evaluate interventions to mitigate CIPN. Efforts to incentivize this translation are needed.

OBJECTIVE: To examine whether blocking multiple points of the angiogenesis pathway by addition of sorafenib, a multi-kinase inhibitor against VEGFR2/3, Raf, c-Kit, and PDGFR, to bevacizumab would yield clinical activity in ovarian cancer (OvCa). METHODS: This phase II study tested bevacizumab plus sorafenib in two cohorts; bevacizumab-naïve and bevacizumab-exposed patients. Bevacizumab (5 mg/kg IV every 2 weeks) was given with sorafenib 200 mg bid 5 days-on/2 days-off. The primary objective was response rate using a Simon two-stage optimal design. Progression-free survival (PFS) and toxicity were the secondary endpoints. Exploratory correlative studies included plasma cytokine concentrations, tissue proteomics and dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI). RESULTS: Between March 2007 and August 2012, 54 women were enrolled, 41 bevacizumab-naive and 13 bevacizumab-prior, with median 5 (2-9) and 6 (5-9) prior systemic therapies, respectively. Nine of 35 (26%) evaluable bevacizumab-naive patients attained partial responses (PR), and 18 had stable disease (SD) ≥ 4 months. No responses were seen in the bevacizumab-prior group and 7 (54%) patients had SD ≥ 4 months, including one exceptional responder with SD of 27 months. The overall median PFS was 5.5 months (95%CI: 4.0-6.8 months). Treatment-related grade 3/4 adverse events (≥5%) included hypertension (17/54 [31%]; grade 3 in 16 patients and grade 4 in one patient) and venous thrombosis or pulmonary embolism (5/54 [9%]; grade 3 in 4 patients and grade 4 in one patient). Pretreatment low IL8 concentration was associated with PFS ≥ 4 months (p = .031). CONCLUSIONS: The bevacizumab and sorafenib combination did not meet the pre-specified primary endpoint although some clinical activity was seen in heavily-pretreated bevacizumab-naive OvCa patients with platinum-resistant disease. Anticipated class toxicities required close monitoring and dose modifications.

BACKGROUND: We examined factors associated with postoperative complications, 1-year overall and cancer-specific survival after epithelial ovarian cancer (EOC) diagnosis. METHODS: Patients who underwent surgery for EOC between 2004 and 2013 were included. Multivariable models analyzed postoperative complications, overall survival, and cancer-specific survival. RESULTS: Among 5223 patients, surgical complications were common. Postoperative complications correlated with increased odds of overall and disease-specific survival at 1 y. Receipt of chemotherapy was similar among women with and without postoperative complications and was independently associated with a reduction in the hazard of overall and disease-specific death at 1-year. Extensive pelvic and upper abdomen surgery resulted in 2.26 times the odds of postoperative complication, but was associated with longer 1-year overall 0.53 (0.35, 0.82) and disease-specific survival 0.54 (0.34, 0.85). CONCLUSIONS: Although extent of surgery was associated with complications, the survival benefit from comprehensive surgery offset the risk. Tailored surgical treatment for women with EOC may improve outcomes.

To examine whether (a) non-minority participants differed from racial minority participants in the understanding of biospecimens collected for research purposes, (b) patients differed from comparison group in their understanding of the ways their biospecimens could be used by researchers, and (c) participants received adequate information before consenting to donate blood for research studies. We analyzed cross-sectional data from female breast cancer patients scheduled to receive chemotherapy at the National Cancer Institute (NCI) Community Oncology Research Program (NCORP) clinical sites and a healthy comparison group. After reading a consent form related to biospecimens and consenting to participate in a clinical trial, participants' understanding of biospecimen collection was evaluated. Linear models were used to compare scores between non-minority and racial minority participants as well as cancer and non-cancer comparisons adjusting for possible confounding factors. A total of 650 participants provided evaluable data; 592 were non-minority (Caucasian) and 58 participants were a racial minority (71% Black and 29% other). There were 427 cancer patients and 223 comparisons. Non-minority participants scored higher than racial minorities on relevance-to-care items (diff. = 0.48, CI 0.13-0.80, p = 0.001). Comparison group scored higher than cancer patients on relevance-to-care items (diff. = 0.58, CI 0.37-0.78). A moderate number of the participants exhibited a poor understanding of biospecimen collection across all racial/ethnic backgrounds, but racial minority participants' scores remained lower in the relevance-to-care subscale even after adjusting for education and reading level. Differences were also noted among the patients and comparison group. Researchers should facilitate comprehension of biospecimen collection for all study participants, especially racial minority participants.

Insights from basic science dissecting carcinogenesis in the fallopian tube and ovary have led to a deeper understanding of the origin, molecular characteristics, and types of ovarian cancers. This logically then has led to the development of novel approaches to treat ovarian cancer. Increasingly, novel agents are being developed to target the different growth pathways. The identification of molecular markers associated with different histopathologies has resulted in newer clinical trial designs to capture both clinical and translational endpoints. Unique molecular characteristics in DNA damage and repair pathways and unique cell surface markers have driven new drug development, yielding promise for both patients with platinum-sensitive and platinum-resistant ovarian cancers. Specific examples described include the histology-selective mutations, such as ARID1A in clear cell and endometrioid ovarian cancers; the rationale for using cell cycle checkpoint inhibitors when there already is a p53-mediated loss of cell cycle checkpoint regulation or combinations of agents that will both induce neoantigen formation and unleash immune modulators; and techniques to enhance the therapeutic delivery of known agents. A systematic and thoughtful approach to combining agents in clinical trials is needed so that irrespective of the trial outcomes, the results inform both clinical and translational endpoints.

The patient-reported outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) complements capture of symptomatic adverse events (AEs) by clinicians. Previous trials have typically used a limited subset of relevant symptomatic AEs to reduce patient burden. We aimed to determine the feasibility of administering all 80 AEs included in the PRO-CTCAE library by approaching consecutive patients enrolled in a large academic phase I program at three points in time. Here, we report a preplanned analysis after enrolling the first 20 patients. All items were answered on 51 of 56 potential visits (adherence 91%). Three (5%) additional PRO-CTCAE assessments were partially completed, and two (4%) were missed because of conflicting appointments. No patient withdrew consent or chose not to complete the assessments once enrolled on study. Future trials of experimental drugs that incorporate the PRO-CTCAE should consider using this unselected approach to identify adverse events more completely.

PURPOSE: To evaluate factors associated with compliance to the National Comprehensive Cancer Network (NCCN) guidelines for BRCA1/2 testing and identify groups who are at risk of under- and over-use of BRCA1/2 testing. METHODS: Data included 20,758 women from Dr. Susan Love Research Foundation's The Health of Women (HOW) Study®. Multinomial logistic regression was used to examine the association of socioeconomic and demographic characteristics with whether the woman was over-, under-, or appropriately tested for BRCA1/2 mutations, per 2015 NCCN guidelines. RESULTS: 3894 women (18.8%) reported BRCA1/2 testing. 5628 (27.1%) women who met NCCN criteria for testing were not tested. Among women with a history of breast cancer, those without health insurance were more likely to be under-tested (OR 2.04, 95% CI 1.15-3.60) than those with managed care insurance, and higher education was associated with a lower likelihood of under-testing (Graduate/professional degree OR 0.71, 95% CI 0.55-0.91). CONCLUSION: Almost 30% of women were under-tested, indicating that many high-risk women who may benefit from genetic testing are currently being missed. Without appropriate testing, providers are unable to tailor screening recommendations to those carrying mutations who are at highest risk. Patient and healthcare provider education and outreach targeted to low-income and under-served populations may assist in reducing under-testing.

PURPOSE OF REVIEW: Cardiovascular effects from cancer treatment remains a leading cause of treatment-associated morbidity and mortality among cancer survivors. The National Cancer Institute and National Heart, Lung, and Blood Institute convened a Workshop in June 2018 entitled "Changing Hearts and Minds: Improving Outcomes in Cancer Treatment-Related Cardiotoxicity" to highlight progress, ongoing work, and update scientific priorities since the 2013 Workshop. Here we will describe these advances and provide an overview of the research priorities identified. RECENT FINDINGS: Since 2013, the National Institutes of Health has increased its support of cancer treatment-related cardiotoxicity research through the funding of grants and coordination of internal and external working groups. Workshop participants identified knowledge gaps and recommended over 20 new promising opportunities in basic and clinical cardiotoxicity research. Significant progress on mechanisms, detection, management, and prevention of cardiotoxicity has been made over the past 5 years, yet some critical gaps remain.

PURPOSE: Social determinants may influence health-related quality of life (HRQOL) among women with ovarian cancer, potentially creating disparities in clinical outcomes. We investigated the relationship between HRQOL and social determinants of health, including travel distance to access cancer care and health insurance type, among women participating in a randomized trial of primary adjuvant treatment for advanced ovarian cancer. METHODS: The Functional Assessment of Cancer Therapy-Ovarian (FACT-O) questionnaire captured HRQOL (physical well-being, functional well-being, ovarian-specific, and trial outcome index [TOI]) prior to chemotherapy (baseline), during the trial, and 84 weeks after initiation of chemotherapy for women with advanced epithelial ovarian, primary peritoneal, or fallopian tube cancer. We constructed bivariate and multivariable linear mixed effects models examining the associations of social determinants of health (individual-level and contextual factors) with HRQOL scores at 84 weeks, clustering participants (n = 993) within treatment centers, and Census regions and controlling for baseline HRQOL. RESULTS: Most individual-level (race, age, cancer stage, adverse events) and contextual (travel distance to treatment center, community socioeconomic status) factors were not statistically significantly associated with HRQOL. Compared to participants with private health insurance, other participants had lower mean HRQOL (physical well-being: public insurance, - 1.00 (standard error[SE] = 0.49) points, uninsured, - 1.93 (SE = 0.63) points; functional well-being: public, - 1.29 (SE = 0.59), uninsured, - 1.98 (SE = 0.76); ovarian cancer-specific: public, - 1.60 (SE = 0.59), uninsured, - 1.66 (SE = 0.75); TOI: public, - 3.81 (SE = 1.46), uninsured, - 5.51 (SE = 1.86); all p < .05). CONCLUSIONS: Private health insurance was associated with improved HRQOL at the completion of treatment for advanced stage ovarian cancer. Implications of health insurance on HRQOL should be further investigated, particularly among women with ovarian cancer who receive standard of care treatment.

BACKGROUND: High-grade serous ovarian carcinoma is characterised by TP53 mutations, DNA repair defects, and genomic instability. We hypothesised that prexasertib (LY2606368), a cell cycle checkpoint kinase 1 and 2 inhibitor, would be active in BRCA wild-type disease. METHODS: In an open-label, single-centre, two-stage, proof-of-concept phase 2 study, we enrolled women aged 18 years or older with measurable, recurrent high-grade serous or high-grade endometrioid ovarian carcinoma. All patients had a negative family history of hereditary breast and ovarian cancer or known BRCA wild-type status, measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, Eastern Cooperative Oncology Group performance status score 0-2, and adequate haematological, renal, hepatic, and bone-marrow function. Patients received intravenous prexasertib 105 mg/m2 administered over 1 h every 14 days in 28-day cycles until disease progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint of investigator-assessed tumour response, based on RECIST version 1.1, was assessed per protocol (assessable patients who had undergone CT imaging at baseline and attended at least one protocol-specified follow-up) and by intention to treat. The final analysis of this cohort of patients with BRCA wild-type high-grade serous ovarian carcinoma is reported here. This ongoing trial is registered with ClinicalTrials.gov, number NCT02203513, and continues to enrol patients for the BRCA-mutated ovarian cancer cohort. FINDINGS: Between Jan 20, 2015, and Nov 2, 2016, we enrolled 28 women with a median age of 64 years (IQR 58·0-69·5) who had previously received a median of 5·0 (IQR 2·5-5·0) systemic therapies. Most patients (22 [79%]) had platinum-resistant or platinum-refractory disease. All women received at least one dose of prexasertib, but four (14%) of 28 patients were not assessable for RECIST response. Eight (33%, 95% CI 16-55) of 24 patients assessable per protocol had partial responses. In the intention-to-treat population, eight (29%, 95% CI 13-49) of 28 had a partial responses. The most common (in >10% patients) grade 3 or 4 treatment-emergent adverse events were neutropenia in 26 (93%) of 28 patients, reduced white blood cell count in 23 (82%), thrombocytopenia in seven (25%), and anaemia in three (11%). Grade 4 neutropenia was reported in 22 (79%) patients after the first dose of prexasertib and was transient (median duration 6 days [IQR 4-8]) and recovered without growth-factor support in all cases. The treatment-related serious adverse event of grade 3 febrile neutropenia was reported in two (7%) patients. One patient died during the study due to tumour progression. INTERPRETATION: Prexasertib showed clinical activity and was tolerable in patients with BRCA wild-type high-grade serous ovarian carcinoma. This drug warrants further development in this setting, especially for patients with platinum-resistant or platinum-refractory disease.

BACKGROUND: Ovarian failure is a common toxic effect of chemotherapy. Studies of the use of gonadotropin-releasing hormone (GnRH) agonists to protect ovarian function have shown mixed results and lack data on pregnancy outcomes. METHODS: We randomly assigned 257 premenopausal women with operable hormone-receptor-negative breast cancer to receive standard chemotherapy with the GnRH agonist goserelin (goserelin group) or standard chemotherapy without goserelin (chemotherapy-alone group). The primary study end point was the rate of ovarian failure at 2 years, with ovarian failure defined as the absence of menses in the preceding 6 months and levels of follicle-stimulating hormone (FSH) in the postmenopausal range. Rates were compared with the use of conditional logistic regression. Secondary end points included pregnancy outcomes and disease-free and overall survival. RESULTS: At baseline, 218 patients were eligible and could be evaluated. Among 135 with complete primary end-point data, the ovarian failure rate was 8% in the goserelin group and 22% in the chemotherapy-alone group (odds ratio, 0.30; 95% confidence interval [CI], 0.09 to 0.97; two-sided P=0.04). Owing to missing primary end-point data, sensitivity analyses were performed, and the results were consistent with the main findings. Missing data did not differ according to treatment group or according to the stratification factors of age and planned chemotherapy regimen. Among the 218 patients who could be evaluated, pregnancy occurred in more women in the goserelin group than in the chemotherapy-alone group (21% vs. 11%, P=0.03); women in the goserelin group also had improved disease-free survival (P=0.04) and overall survival (P=0.05). CONCLUSIONS: Although missing data weaken interpretation of the findings, administration of goserelin with chemotherapy appeared to protect against ovarian failure, reducing the risk of early menopause and improving prospects for fertility.

PURPOSE: Although aromatase inhibitors (AIs) prolong survival in post-menopausal breast cancer (BC) patients, AI-associated arthralgia can lead to discontinuation. Obese patients have higher rates of AI arthralgia than non-obese patients, but treatment options are limited. Omega-3 fatty acid (O3-FA) treatment for AI arthralgia has produced mixed results. METHODS: We performed an exploratory analysis of SWOG S0927, a multicenter randomized placebo-controlled trial of O3-FA use for AI arthralgia. Post-menopausal women with stage I-III BC taking an AI were randomized to 24 weeks of O3-FAs or placebo. Brief Pain Inventory (BPI) questionnaires and fasting serum were collected at baseline, 12, and 24 weeks. The BPI assessment included worst pain, average pain, and pain interference scores (range 0-10). RESULTS: Among the 249 participants, 139 had BMI < 30 kg/m2 (56%) and 110 had BMI ≥ 30 kg/m2 (44%). Among obese patients, O3-FA use was associated with significantly lower BPI worst pain scores at 24 weeks compared with placebo (4.36 vs. 5.70, p = 0.02), whereas among non-obese patients, there was no significant difference in scores between treatment arms (5.27 vs. 4.58, p = 0.28; interaction p = 0.05). Similarly, O3-FA use was associated with lower BPI average pain and pain interference scores at 24 weeks compared with placebo among obese patients, but no significant difference between treatment arms in non-obese patients (interaction p = 0.005 and p = 0.01, respectively). CONCLUSIONS: In obese BC patients, O3-FA use was associated with significantly reduced AI arthralgia compared to placebo.
