Background: Oncology advanced practitioners (APs), including nurse practitioners, clinical nurse specialists, physician assistants, and clinical pharmacists contribute significantly to quality cancer care. Advanced practitioners enhance value across the spectrum of cancer care. Research is an underdeveloped component of quality care, as well as an underdeveloped component of AP practice. Understanding research-related attitudes and roles of APs could lead to enhanced clinical trial accrual, conduct, and protocol development. Methods: A nationwide survey addressing attitudes, beliefs, and roles of APs regarding clinical research was distributed by the Association of Community Cancer Centers (ACCC) and Harborside in early 2020. Results: 408 oncology APs completed the survey. Thirty-five percent practice in an academic setting and 62% in the community. Nearly all respondents believe clinical trials are important to improve care, and over 90% report clinical trials are available at their practice. About 80% report being comfortable discussing the topic of clinical trials with patients and are involved in the care of trial participants. Sixty percent are comfortable discussing available trials, and 38% routinely explore available trials with patients. While 70% report approaching eligible patients about trials, only 20% report doing so “a great deal” or “a lot.” Ninety percent report that APs should play a role in clinical research, and 73% want to be more involved. Barriers identified to greater AP clinical trial involvement include lack of time, inadequate awareness of trial specifics, and a lack of a formal role in protocol development and leadership. Conclusions: Advanced practitioners are engaged and interested in clinical trials and believe clinical research is important to improve cancer care. Multidisciplinary team integration, trials-related education, and policy change are needed to employ APs to their full potential within cancer clinical trials.

As part of ongoing efforts to meaningfully improve recruitment, enrollment, and accrual of older adults into cancer clinical trials, the National Cancer Institute (NCI) sponsored a workshop with experts across the country entitled Engaging Older Adults in the NCI Clinical Trials Network: Challenges and Opportunities. Three working groups, including Study Design, Infrastructure, and Stakeholders, were formed, who worked together to offer synergistic improvements in the system. Here, we summarize the workshop discussions of the Infrastructure Working Group, whose goal was to address infrastructural challenges, identify underlying resources, and offer solutions to facilitate accrual of older adults into cancer clinical trials. Based on preconference work and workshop discussions, four key recommendations to strengthen NCI infrastructure were proposed: 1) further centralize resources and expertise; 2) provide training for clinical research staff; (3) develop common data elements; and 4) evaluate what works and does not work. These recommendations provide a strategy to improve the infrastructure to enroll more older adults in cancer clinical trials.

BACKGROUND Older patients with advanced cancer who are 100% certain they will be cured pose unique challenges for clinical decision making, but to the authors' knowledge, the prevalence and correlates of absolute certainty about curability (ACC) are unknown. METHODS Cross-sectional data were collected in a geriatric assessment trial. ACC was assessed by asking patients, "What do you believe are the chances that your cancer will go away and never come back with treatment?" Response options were 100% (coded as ACC), >50%, 50/50

Older adults with advanced cancer are at a high risk for treatment toxic effects. Geriatric assessment evaluates ageing-related domains and guides management. We examined whether a geriatric assessment intervention can reduce serious toxic effects in older patients with advanced cancer who are receiving high risk treatment (eg, chemotherapy).In this cluster-randomised trial, we enrolled patients aged 70 years and older with incurable solid tumours or lymphoma and at least one impaired geriatric assessment domain who were starting a new treatment regimen. 40 community oncology practice clusters across the USA were randomly assigned (1:1) to the intervention (oncologists received a tailored geriatric assessment summary and management recommendations) or usual care (no geriatric assessment summary or management recommendations were provided to oncologists) by means of a computer-generated randomisation table. The primary outcome was the proportion of patients who had any grade 3-5 toxic effect (based on National Cancer Institute Common Terminology Criteria for Adverse Events version 4) over 3 months. Practice staff prospectively captured toxic effects. Masked oncology clinicians reviewed medical records to verify. The study was registered with ClinicalTrials.gov, NCT02054741.Between July 29, 2014, and March 13, 2019, we enrolled 718 patients. Patients had a mean age of 77·2 years (SD 5·4) and 311 (43%) of 718 participants were female. The mean number of geriatric assessment domain impairments was 4·5 (SD 1·6) and was not significantly different between the study groups. More patients in intervention group compared with the usual care group were Black versus other races (40 [11%] of 349 patients vs 12 [3%] of 369 patients; p0·0001) and had previous chemotherapy (104 [30%] of 349 patients vs 81 [22%] of 369 patients; p=0·016). A lower proportion of patients in the intervention group had grade 3-5 toxic effects (177 [51%] of 349 patients) compared with the usual care group (263 [71%] of 369 patients; relative risk [RR] 0·74 (95% CI 0·64-0·86; p=0·0001). Patients in the intervention group had fewer falls over 3 months (35 [12%] of 298 patients vs 68 [21%] of 329 patients; adjusted RR 0·58, 95% CI 0·40-0·84; p=0·0035) and had more medications discontinued (mean adjusted difference 0·14, 95% CI 0·03-0·25; p=0·015).A geriatric assessment intervention for older patients with advanced cancer reduced serious toxic effects from cancer treatment. Geriatric assessment with management should be integrated into the clinical care of older patients with advanced cancer and ageing-related conditions.National Cancer Institute.

Objectives Rural-urban disparities in the experiences of caregivers of older adults with advanced cancer may exist. This study examined factors associated with caregiver mastery and burden and explored whether rural-urban disparities in caregiver outcomes differed by education. Materials and methods Longitudinal data (baseline, 4–6 weeks, and 3 months) on caregivers of older adults (≥ 70) with advanced cancer were obtained from a multicenter geriatric assessment (GA) trial ( ClinicalTrials.gov : NCT02107443 ). Rurality was determined based on 2010 Rural-Urban Commuting Area codes. Caregivers' education was categorized as ≥ some college vs ≤ high school. Caregiver outcomes included Ryff Environmental Mastery (scored 7–35) and Caregiver Reaction Assessment (including self-esteem, disrupted schedules, financial problems, lack of social support, and health problems; each scored 1–5). Separate linear mixed models with interaction term of education and rurality were performed. Results Of 414 caregivers, 64 (15.5%) were from rural areas and 263 (63.5%) completed ≥ some college. Rurality was significantly associated with more disrupted schedules (β = 0.21), financial problems (β = 0.17), and lack of social support (β = 0.11). A significant interaction between education and rurality was found, with rurality associated with lower mastery (β = −1.27) and more disrupted schedule (β = 0.25), financial problems (β = 0.33), and lack of social support (β = 0.32) among caregivers with education ≤ high school. Conclusion Our study identifies subgroups of caregivers who are vulnerable to caregiving burden, specifically those from rural areas and with lower education. Multifaceted interventions are needed to improve caregivers' competency and reduce caregiving burden.

e13525 Background: Cancer care delivery Research (CCDR) is a multidisciplinary science that seeks to improve clinical outcomes and patient well-being by intervening on patient, clinician and organizational factors that influence care delivery. Many CCDR protocols also use implementation science to evaluate how best to introduce promising and previously established interventions into everyday care. These types of studies do not typically utilize research and clinic staff in the same ways as traditional treatment trials. One of the main goals of CCDR is for clinics to continue to use the intervention past the time of protocol participation. Even though these studies intend to improve cancer care delivery in the community, it is often difficult for community sites to embrace and prioritize CCDR due to their differences from typical treatment trials. Our recent observatory research highlights one Minority/Underserved (M/U) NCORPs key strategies for successful implementation of a decision aid CCDR trial in a community setting. Methods: HI M/U NCORP identified multiple steps prior to opening and enrolling patients onto a CCDR implementation trial at our community site. Step 1) Identifying an engaged physician and an advanced practice provider (APP) to be champions for the trial at the clinic. 2) Identifying and engaging key clinic staff and ensuring the workflow is feasible in the clinic. Key processes utilized during the entire course of the trial were also identified. 3) Research staff only coordinating and completing purely study related activities and not implementation activities. 4) Engaging other non-traditionally research involved administration staff and department management. 5) Utilizing ongoing clinic staff input to enhance trial success and optimize clinic workflow. Results: Using the strategies mentioned above, Hawai’i M/U NCORP was able to successfully open and enroll to an internet based CCDR implantation trial at a community clinic from 2019 through 2021. Not only were we able to achieve the highest accrual to a CCDR implementation trial to date within our NCORP, but also managed to do so at a clinic that had previously had minimal involvement in clinical trials in the past. Providers within the clinic received very positive reviews from their patients regarding the trial elements and the clinic has been working toward continuing the use of the material introduced by this CCDR implantation trial. Conclusions: Our successful use of these strategies described have not only been beneficial for our NCORP, but has made a large impact on improving the quality of clinic care at a busy community site. Our involved multi-step opening strategies set the stage for a seamless clinic workflow throughout the trial. This research has proven that these strategies can lead to the success of CCDR implementation studies in a community practice.

6547 Background: The University of Hawaii Cancer Center (UHCC) Minority/Underserved NCI Community Oncology Research Program (Hawaii MU NCORP) provides access to NCI-sponsored clinical trials in Hawaii. The Hawaii MU NCORP is dedicated to increasing minority and underserved accruals to clinical trials. Native Hawaiian women have the highest breast cancer incidence and mortality; only 26% of Micronesian women in Hawaii over the age of 40 have ever had a mammogram. In 2018, the Hawaii MU NCORP became a recruitment site for the ECOG-ACRIN Tomosynthesis Mammographic Imaging Screening Trial (TMIST). A pilot study was launched in 2019, to support our NCORP recruitment of underrepresented Native Hawaiian and other Pacific Islander (NHPI) women to the TMIST study. Subsequently, specific funding was provided by the NCI’s Center to Reduce Cancer Health Disparities that enabled the UHCC’s Office of Community Outreach and Engagement (COE) to develop an effective multilevel recruitment strategy together with the Hawaii MIU NCORP. Methods: To foster community awareness of the TMIST study among NHPI women, the UHCC COE hired a Community Health Educator (CHE). The CHE, a Pacific Islander woman, utilized small group educational sessions to provide culturally and linguistically appropriate cancer prevention information and promote the TMIST study to NHPI women in Hawaii. The CHE worked in partnership with Hawaii MU NCORP clinical research associates (CRAs) in these efforts. In 2020, statewide COVID-19 health and safety protocols were enacted, limiting public group interactions in Hawaii. Despite this challenge, the CHE successfully adapted the in-person educational sessions on clinical trials and TMIST to conduct sessions using Zoom and Facebook Messenger. Results: Before the hire of the CHE in 2019, only one Pacific Islander (Micronesian) woman was recruited to the TMIST in Hawaii. The CHE conducted 21 community health events with 426 attendees from 2019 to 2021. The Hawaii MU NCORP NHPI TMIST enrollment went from the 9.9% in 2018 to 2019, to 20.1% in 2019 to 2020 and to 33% in 2020 to 2021. To date, 18 Micronesian, 52 Native Hawaiian and 6 Other Pacific Islander women out of 353 participants ware enrolled. Conclusions: The multilevel intervention of our CHE, in collaboration with NCORP staff providing clinical trial awareness training and community outreach, resulted in increasing the enrollment of NHPI women to the TMIST Trial. CHE-led community health education sessions on cancer prevention can be delivered using emergent technologies and social media. The use of culturally and gender concordant CHEs working with CRAs have the potential to increase awareness and accruals to cancer clinical trials.

Context Older adults with advanced cancer face uncertainty related to their disease and treatment. Objectives To evaluate the associations of uncertainty with psychological health and quality of life (QoL) in older adults with advanced cancer. Methods Secondary cross-sectional analysis of baseline data from a national clustered geriatric assessment trial. Patients 70 years and older with advanced cancer considering a new line of chemotherapy were recruited. We measured uncertainty using the modified nine-item Mishel Uncertainty in Illness Scale. Dependent variables included anxiety (Generalized Anxiety Disorder-7), depression (Generalized Depression Scale-15), distress (distress thermometer), QoL (Functional Assessment of Cancer Therapy—General), and emotional well-being (Functional Assessment of Cancer Therapy—General subscale). We used multivariate linear regression analyses to evaluate the association of uncertainty with each dependent variable. We conducted a partial least squares analysis with a variable importance in projection (VIP) plot to assess the contribution of individual variables to the model. Variables with a VIP Results We included 527 patients (median age 76 years; range 70–96). In multivariate analyses, higher levels of uncertainty were significantly associated with greater anxiety (β = 0.11; SE = 0.04), depression (β = 0.09; SE = 0.02), distress (β = 0.12; SE = 0.02), as well as lower QoL (β = −1.08; SE = 0.11) and emotional well-being (β = −0.29; SE = 0.03); the effect sizes were considered small. Uncertainty items related to disease and treatment were most strongly associated with psychological health and QoL scores (all VIP >0.8). Conclusion Uncertainty among older patients with advanced cancer is associated with worse psychological health and QoL. Tailored uncertainty management strategies are warranted.

Background Black race is associated with worse outcomes in early breast cancer. We evaluated clinicopathologic characteristics, the 21-gene recurrence score (RS), treatment delivered, and clinical outcomes by race and ethnicity among women who participated in the Trial Assigning Individualized Options for Treatment. Methods The association between clinical outcomes and race (White, Black, Asian, other or unknown) and ethnicity (Hispanic vs non-Hispanic) was examined using proportional hazards models. All P values are 2-sided. Results Of 9719 eligible women with hormone receptor–positive, HER2-negative, node-negative breast cancer, there were 8189 (84.3%) Whites, 693 (7.1%) Blacks, 405 (4.2%) Asians, and 432 (4.4%) with other or unknown race. Regarding ethnicity, 889 (9.1%) were Hispanic. There were no substantial differences in RS or ESR1, PGR, or HER2 RNA expression by race or ethnicity. After adjustment for other covariates, compared with White race, Black race was associated with higher distant recurrence rates (hazard ratio [HR] = 1.60, 95% confidence intervals [CI] = 1.07 to 2.41) and worse overall survival in the RS 11-25 cohort (HR = 1.51, 95% CI = 1.06 to 2.15) and entire population (HR = 1.41, 95% CI = 1.05 to 1.90). Hispanic ethnicity and Asian race were associated with better outcomes. There was no evidence of chemotherapy benefit for any racial or ethnic group in those with a RS of 11-25. Conclusions Black women had worse clinical outcomes despite similar 21-gene assay RS results and comparable systemic therapy in the Trial Assigning Individualized Options for Treatment. Similar to Whites, Black women did not benefit from adjuvant chemotherapy if the 21-gene RS was 11-25. Further research is required to elucidate the basis for this racial disparity in prognosis.

168 Background: According to the Institute of Medicine, care coordination (CC) is a critical component of high-quality cancer care; however, many patients with cancer continue to experience fragmented care. CC experiences among cancer clinical trial (CT) participants are relatively unknown. Using mixed methods, we examined perceptions of CC among patients enrolled on therapeutic CTs conducted through the Hawaii Minority/Underserved NCI Community Oncology Research Program (NCORP). Methods: Forty-five CT participants completed the validated Care Coordination Instrument (CCI). The CCI assesses cancer patients’ perceptions of CC overall and across Communication, Navigation, and Operational domains. Data from 45 non-CT participants matched by age, gender, cancer type (breast, GI, other), and clinical stage from our prior studies served as a control group. Paired t-tests were used to compare the CCI scores between the two groups. Three semi-structured focus group interviews were conducted with 14 CT participants in 2020 and 2021. Results: The mean age of CT participants was 61.7 ( SD = 9.4), with the majority being female (67%) and Asian (56%). The most common cancer disease sites were breast (27%) and GI (16%). CT participants reported significantly higher total CC scores than non-participants ( p =.0008). Similar trends were found for Navigation ( p =.007) and Operational ( p =.001) domain scores. 56% of CT participants reported receiving moderate to high-intensity CC assistance from their clinical research professionals (CRPs). Content analysis of focus group discussions revealed that the majority of CT participants’ comments aligned with CC domains; 42% Communication, 30% Navigation, and 28% Operational. Nearly half of focus group discussions centered on CRPs (47%), including CC support provided by CRPs (26%). Other key themes that emerged from the focus groups included general CT experiences (22%) and CRP involvement as an additional benefit to CT participation (15%). Conclusions: Clinical trial participants perceive better CC than non-CT participants, partly attributed to CC support provided by CRPs. Our findings highlight a generally unrecognized yet integral role of CRPs as part of a cancer clinical trial care team. CRP involvement may be an additional benefit of CT participation and contribute to improved quality and value for patient-centered cancer care.

Over half of all cancer patients receiving taxane-, platinum-, or vinca alkaloid-based chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN), which includes numbness, tingling, pain, cold sensitivity, and motor impairment in the hands and feet. CIPN is a dose-limiting toxicity, potentially increasing mortality. There are no FDA-approved drugs to treat CIPN, and behavioral interventions such as exercise are promising yet understudied. This secondary analysis of our nationwide phase III randomized controlled trial of exercise for fatigue examines (1) effects of exercise on CIPN symptoms, (2) factors that predict CIPN symptoms, and (3) factors that moderate effects of exercise on CIPN symptoms. Cancer patients (N = 355, 56 ± 11 years, 93% female, 79% breast cancer) receiving taxane-, platinum-, or vinca alkaloid-based chemotherapy were randomized to chemotherapy or chemotherapy plus Exercise for Cancer Patients (EXCAP©®). EXCAP is a standardized, individualized, moderate-intensity, home-based, six-week progressive walking and resistance exercise program. Patients reported CIPN symptoms of numbness and tingling and hot/coldness in hands/feet (0–10 scales) pre- and post-intervention. We explored baseline neuropathy, sex, age, body mass index, cancer stage, and cancer type as possible factors associated with CIPN symptoms and exercise effectiveness. Exercise reduced CIPN symptoms of hot/coldness in hands/feet (−0.46 units, p = 0.045) and numbness and tingling (− 0.42 units, p = 0.061) compared to the control. Exercise reduced CIPN symptoms more for patients who were older (p = 0.086), male (p = 0.028), or had breast cancer (p = 0.076). Exercise appears to reduce CIPN symptoms in patients receiving taxane-, platinum-, or vinca alkaloid-based chemotherapy. Clinicians should consider prescribing exercise for these patients.

Objectives Older self-perceived age is associated with poor health and higher healthcare utilization in the geriatric population. We evaluated the associations of self-perceived age with geriatric assessment (GA) domain impairments in older adults with cancer. Methods This was a secondary analysis of baseline data from a GA cluster-randomized trial (URCC 13070; PI: Mohile). We included patients aged ≥70 with incurable stage III/IV solid tumor or lymphoma considering or receiving treatment and had ≥1 GA domain impairment other than polypharmacy. Multivariate analyses were used to evaluate the associations of age difference between chronological and self-perceived age (categorized into “feeling younger than chronological age” vs. “feeling the same or older than their chronological age”) with GA domain impairments. Results We included 533 patients; mean age was 76.6 (SD 5.2). On multivariate analyses, compared to those who felt younger than their chronological age, those who felt the same or older were more likely to have impairments in physical performance [Adjusted Odds Ratio (AOR) 5.42, 95% Confidence Interval (CI) 1.69–17.40)], functional status (AOR 2.31, 95% CI 1.73–3.07), comorbidity (AOR 1.62, 95% CI 1.20–2.19), psychological health (AOR 2.62, 95% CI 1.85–3.73), and nutrition (AOR 1.65, 95% CI 1.20–2.28). They were also more likely to screen positively for polypharmacy (AOR 1.86, 95% CI 1.30–2.65). Conclusions Older adults with cancer who felt the same or older than their chronological age were more likely to have GA domain impairments. Further studies are needed to better understand the relationships between self-perceived age, aging-related conditions, and outcomes in this population.

Importance A high 21-gene recurrence score (RS) by breast cancer assay is prognostic for distant recurrence of early breast cancer after local therapy and endocrine therapy alone, and for chemotherapy benefit. Objective To describe clinical outcomes for women with a high RS who received adjuvant chemotherapy plus endocrine therapy in the TAILORx trial, a population expected to have a high distant recurrence rate with endocrine therapy alone. Design, Setting, and Participants In this secondary analysis of data from a multicenter randomized clinical trial, 1389 women with hormone receptor–positive, ERBB2-negative, axillary node-negative breast cancer, and a high RS of 26 to 100 were prospectively assigned to receive adjuvant chemotherapy in addition to endocrine therapy. The analysis was conducted on on May 12, 2019. Interventions The adjuvant chemotherapy regimen was selected by the treating physician. Main Outcomes and Measures Freedom from recurrence of breast cancer at a distant site, and freedom from recurrence, second primary cancer, and death (also known as invasive disease-free survival [IDFS]). Results Among the 9719 eligible women, with a mean age of 56 years (range 23-75 years), 1389 (14%) had a recurrence score of 26 to 100, of whom 598 (42%) had an RS of 26 to 30 and 791 (58%) had an RS of 31 to 100. The most common chemotherapy regimens included docetaxel/cyclophosphamide in 589 (42%), an anthracycline without a taxane in 334 (24%), an anthracycline and taxane in 244 (18%), cyclophosphamide/methotrexate/5-fluorouracil in 52 (4%), other regimens in 81 (6%), and no chemotherapy in 89 (6%). At 5 years, the estimated rate of freedom from recurrence of breast cancer at a distant site was 93.0% (standard error [SE], 0.8%), freedom of recurrence of breast cancer at a distant and/or local regional site 91.0% (SE, 0.8%), IDFS 87.6% (SE, 1.0%), and overall survival 95.9% (SE, 0.6%). Conclusions and Relevance The estimated rate of freedom from recurrence of breast cancer at a distant site in women with an RS of 26 to 100 treated largely with taxane and/or anthracycline-containing adjuvant chemotherapy regimens plus endocrine therapy in the prospective TAILORx trial was 93% at 5 years, an outcome better than expected with endocrine therapy alone in this population.

Active patient partner engagement with SCOREboard – a diverse group of older patients with cancer, caregivers of older patients with cancer, survivors, and patient advocates – to conduct the largest randomized geriatric assessment clinical trial to date, has been shown to be feasible and resulted in tangible and invaluable benefits for both the research team and patient partners alike. Actively engaging patient partners should be an essential component in the development, conduct, and completion of all clinical research.

Idiopathic thrombocytopenia (ITP) can present as life-threatening bleeding. The diagnosis can be difficult to make, and it is ultimately a diagnosis of exclusion. In the acute phase, the hallmark of treatment is transfusion of necessary blood products and the initiation of both steroids and intravenous immunoglobulin (IVIG) to prevent antibody sequestration of the platelets. Several new medical therapies are available for the non-acute presentation of ITP. The medical management of ITP will be discussed in this chapter.

12003 Background: AIMSS are common and frequently lead to early discontinuation of adjuvant AI therapy. Single nucleotide polymorphisms (SNPs) in candidate genes have been associated with AIMSS and AI discontinuation. The primary objective of E1Z11 was to validate previously identified associations between 10 specific SNPs in candidate genes and AI discontinuation due to AIMSS in a community-based, racially diverse cohort. Methods: Postmenopausal women with hormone receptor-positive stage I-III breast cancer enrolled onto a prospective multi-site cohort study, the majority through the NCI Community Oncology Research Program (NCORP). Participants received anastrozole 1 mg oral daily, and completed patient-reported outcomes (PROs) at baseline, 3, 6, 9, and 12 months. AIMSS was defined as >20% increase in Stanford Health Assessment Questionnaire (HAQ) score over baseline occurring within 1 year of AI therapy. We projected 40% would develop AIMSS and 25% would discontinue AI treatment within 1 year, informing a planned enrollment of 1000 women with a fixed number per strata (600 Caucasian, 200 African-American [AA] & 200 Asian) to provide 80% power to detect an effect size of 1.5-4. SNPs include ESR1 (rs2234693, rs2347868, rs9340835), CYP19A1 (rs1062033, rs4646), TCL1A (rs11849538, rs2369049, rs7158782, rs7159713), and HTR2A (rs2296972). Hardy-Weinberg equilibrium (HWE) was evaluated within each racial subset. SNP genotypes were coded as additive effects on the log odds ratio by coding as 0, 1 or 2 for the count of the minor allele. A Cochran-Armitage trend test was used with a 1-sided alpha of 0.0025 (Bonferroni correction for 10 tests). Results: We enrolled 999 evaluable women (616 Caucasian, 184 AA, 199 Asian). Genotyping was successful in 974 (98%). AIMSS developed in 43%, and AI therapy was discontinued in 12% within 1 year. While more AA and Asians developed AIMSS compared to Caucasians (48% vs 38%, p=0.017; 50% vs 38%, p=0.004), AI discontinuation rates were similar across racial groups. HWE was satisfied for all SNPs at the 5% alpha level, except for TCL1A/rs11849538 (p=0.002) in the AA cohort. None of the 10 SNPs were significantly associated with AI discontinuation or development of AIMSS in the overall population, or in any of the 3 cohorts. Conclusions: Although AIMSS were more common in AA and Asians, AI discontinuation rates were similar in the 3 cohorts. We were unable to prospectively validate 10 SNPs in 4 genes previously associated with AI discontinuation due to AIMSS. Future analyses will include other predictors of AIMSS, PROs, and additional genetic markers for the entire cohort and by race.

e13504 Background: Effective coordination of care (CC) is a critical component of high-quality cancer care; however, many patients with cancer continue to receive poorly coordinated care. CC experiences among therapeutic clinical trial (CT) participants are relatively unknown. We examined cancer patients’ perceptions of CC among CT participants using a validated Care Coordination Instrument (CCI). Methods: The study sample (N = 90) consisted of 45 CT participants and 45 matched non-participants from archival data from our prior CC studies. 171 patients who participated in therapeutic cancer clinical trials through the Hawaii Minority/Underserved NCI Community Oncology Research Program (NCORP) between 2015 and 2020 were contacted for study participation, and 26% completed the CCI. The CCI measures overall perceptions of CC and across 3 domains (Communication, Navigation, Operational). Paired t-tests were used to compare overall and domain scores between CT participants and non-participants. The two groups were matched by age, gender, cancer type (breast, GI, other), and clinical stage. Results: Among CT participants, the mean age was 61.7 ( SD = 9.4), and the majority were female (67%) and Asian (56%). The most common cancer types were breast (27%) and GI (16%), with 24% with stage III disease. CT participants reported significantly higher total CC scores than non-participants (62.5 vs. 55.8; p = .0008). Similar trends were found for Navigation ( p = .007) and Operational ( p = .001) domain scores. 29% of CT participants reported receiving high-intensity CC assistance from their clinical research associates (CRAs), and 27% indicated receiving moderate-level CC assistance. Responses to open-ended questions regarding CC revealed that CT participants received assistance with a variety of CC activities from their CRAs, including scheduling appointments and explaining test results and procedures. Conclusions: Patients who participate in therapeutic cancer clinical trials report more positive perceptions of CC compared to non-participants. Qualitative data suggest that significant care coordination support is provided by the clinical research associate. The results underscore the importance of CC support provided by CRAs who may be an unrecognized component of the healthcare delivery team. CC provided by CRAs may contribute to improved quality and value of cancer care for patients enrolled on therapeutic clinical trials.

e18525 Background: Previous studies in the general population have observed that compared with Non-Hispanic White (NHW) women, Pacific Islander (PI) and Non-Hispanic Black (NHB) women have higher age-adjusted mortality rates from epithelial ovarian cancer (EOC), while Asian Americans (AS) have lower mortality. It is unknown whether these patterns reflect biological differences, environmental exposure or perhaps access to care. Our objective was to investigate whether self-reported race/ethnicity is associated with differences in EOC survival in a Military population where patients have equal access to healthcare. Methods: The study population included women diagnosed with EOC (ovarian, fallopian tube and primary peritoneal cancers) among US Department of Defense beneficiaries reported in the Automated Central Tumor Registry Database (year of diagnosis range: 2001-18). Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression models following participants from their date of diagnosis until last contact or censoring, whichever occurred first. Multivariable models were adjusted for covariates selected a priori because of their known influence on risk of EOC death; age at diagnosis (continuous), histology, stage and receipt of the first course of chemotherapy treatment. We adjusted for year of diagnosis (continuous) to account for possible changes in treatment over time. Results: The study population included 1151 patients diagnosed with EOC: 796 NHW, 111 NHB, 130 AS, 49 PI and 65 Hispanic (HS). All EOC patients had complete information on age at diagnosis, stage and chemotherapy treatment. During a median (interquartile range) follow-up of 3.5 years (1.8-6.7), 702 EOC patients (61%) died of all causes. When comparing crude EOC patient characteristics by racial/ethnic group, NHW had the highest frequency of EOC leading to death (58% vs. < 49% in other groups). There also were differences in histology; NHW and NHB had a higher frequency of serous tumors ( > 56% of EOCs vs. < 52% in other groups); PI had a high proportion of endometrioid histology (14% of EOCs vs. < 11% in others); 10% of EOCs among AS had clear cell histology (vs. < 9% in others). HS had a high percentage of local disease (23% vs. < 20% in others). In multivariable survival analysis adjusting for clinical factors, we observed that compared with NHW, there were no differences in EOC survival by race/ethnicity: AS, HR = 0.80 (95% CI = 0.61-1.05); NHB, HR = 0.96 (95% CI = 0.72-1.28); PI, HR = 0.92 (95% CI = 0.58-1.46); and HS, HR = 0.82 (95% CI = 0.56-1.21). Conclusions: We observed no racial/ethnic disparities in EOC survival in a Military equal access treatment environment. These results highlight the importance of studying how differences in access to healthcare may impact observed racial/ethnic disparities for EOC.

Background: SWOG initiated a cancer care delivery research study of virus infection rates among newly diagnosed cancer patients. This study will inform viral screening guidelines in oncology clinics. Methods: In a first step ‘vanguard’ phase, we evaluated the feasibility of multiple study procedures. Site investigators were surveyed to obtain feedback on study implementation. Results: Much higher enrollment occurred at sites where all physicians participated and viral testing was performed as routine practice. These procedures will be required going forward. Additional protocol changes based on site investigator input were implemented. Conclusion: This multistep protocol design process illustrates how cancer care delivery research studies can adapt to real-world strategies and procedures that exist at community clinics where the predominance of cancer patients are treated.

Background: The Trial Assigning Individualized Options for Treatment (TAILORx) is a prospective trial evaluating the role of endocrine therapy or chemoendocrine therapy in patients 18-75 years of age with estrogen receptor (ER)-positive, HER2-negative breast cancer, a primary tumor between 0.6-5.0 cm, and negative axillary nodes, a population for whom chemotherapy is typically recommended or least considered based on National Comprehensive Cancer Center Network (NCCN) guidelines. Methods: The trial was designed to demonstrate non-inferiority of endocrine therapy compared with chemoendocrine therapy in the randomized group with an Oncotype DX Recurrence Score (RS) of 11-25. Patients with a low RS < 11 were assigned to endocrine therapy alone and with a high RS > 25 assigned to chemoendocrine therapy, and both groups were followed in a prospective registry. The definition of an intermediate RS differed in this trial (RS 11-25) from the original reports (RS 18-30) in order to reduce the risk of chemotherapy undertreatment in patients with a mid-range or low RS (Sparano & Paik. J Clin Oncol 2008; 26:721-728). Results: The trial enrolled 10,273 patients between April 2006 and October 2010, of whom 6907 patients (67.2%) had a mid-range RS of 11-25, 1737 (16.9%) had a high RS > 25, and 1639 (15.9%) had a low RS of < 11. At the fourth planned interim analysis, the ECOG-ACRIN data monitoring committee recommended that the study continue as planned for the randomized group with a RS 11-25, and that the results be released to the investigators for the low risk group with a RS 60 (39%); tumor size < 1 cm (8%), 1-2 cm (61%), > 2 cm (31%); histologic grade low (34%), intermediate (59%), high (7%); breast conservation (68%) or mastectomy (32%). Initial endocrine therapy included tamoxifen in 35%, aromatase inhibitors in 59%, ovarian function suppression in 3%, and unspecified therapy in 3%; 5 patients received adjuvant chemotherapy (1 of whom relapsed). Five-year rates (and 95% confidence intervals [CI]) for low RS group were 99.2% (98.5, 99.6%) for distant relapse free interval, 98.5% (97.7, 99.1%) for relapse-free interval, 93.7% (92.2, 94.9%) for invasive disease free survival, and 98.2% (97.3, 98.7%) for overall survival. Information regarding ER, PR, and HER2 RNA expression will be presented. Conclusions: Despite meeting guidelines for recommending or at least considering adjuvant chemotherapy based on classical clinicopathologic features, the risk of recurrence was very low at 5 years in patients with ER-positive, HER2-negative, axillary node-negative breast cancer and a low RS of < 11 treated with endocrine therapy alone without chemotherapy.

Key Clinical Message Metronidazole is commonly prescribed and has not been known to cause drug‐induced immune thrombocytopenia. We have provided clinical and laboratory evidence with DDabs that metronidazole can cause drug‐induced immune thrombocytopenia (DITP). Providers must be aware of metronidazole causing DITP because recognition of thrombocytopenia is critical and cessation of the drug should occur promptly.

Importance Financial toxicity (FT), unintended and unanticipated financial burden experienced by cancer patients undergoing cancer care, is associated with negative consequences and increased risk of mortality. Older patients (≥70 years) with cancer are at risk for FT, yet data are limited on FT and whether oncologists discuss FT with their patients. Objective To examine the prevalence of FT in older adults with advanced cancer, its association with health-related quality of life (HRQoL), and cost conversations between oncologists and patients. Design, setting, and participants This cross-sectional secondary analysis was performed on baseline data from the Improving Communication in Older Cancer Patients and Their Caregivers study, a cluster randomized trial from 31 community oncology practices across the US that was conducted from October 29, 2014, to April 28, 2017. Participants included 536 patients with advanced cancer who answered 3 questions regarding financial toxicity. Data were analyzed from September 1, 2019, to May 1, 2020. Exposure Older patients undergoing cancer care treatments. Main outcomes and measures The main outcome looked at FT and its association with HRQoL. Three questions were used to identify patients 70 years or older experiencing FT. Multivariable linear regression models were used to assess the independent associations of FT with HRQoL. A single audio-recorded clinic transcript was analyzed within 4 weeks of enrollment for patients with FT. The framework method was used to identify frequency and themes related to cost conversations. Results This study evaluated 536 patients 70 years or older with advanced cancer. Ninety-eight patients (18.3%) reported FT; mean (SD) age was 76.4 (5.4) years; 59 (60.2%) were female, 14 (14.3%) were Black/African American, 91 (92.9%) were not employed, and 29 (29.6%) had Medicare as their sole insurance coverage. On multivariate regression analyses, FT was associated with higher levels of depression (β = 0.81; 95% CI, 0.15-1.48), anxiety (β = 1.67; 95% CI, 0.74-2.61), and distress (β = 0.73; 95% CI, 0.08-1.39) and lower HRQoL (β = -5.30; 95% CI, -8.92 to -1.69). Among those who reported FT, 49% had a conversation with their health care professional about costs. Most conversations (79%) were initiated by oncologists or patients. Four themes were generated from cost conversations: statements regarding cost of care, ability to afford medical prescriptions, indirect consequences associated with inability to work and provide for family, and cost burden in nontreatment domains. Conclusions and relevance In this study, among older adults with advanced cancer, FT is associated with worse HRQoL. Almost half of conversations among patients reporting FT demonstrated costs are being actively discussed. Resources and interventions are needed to manage FT.

33 Background: GA evaluates aging-related domains (e.g., function) known to be associated with cancer treatment toxicity. We found that providing a GA summary with management recommendations to oncologists reduces clinician-rated toxicity in older patients (pts) with advanced cancer receiving high risk treatment (presented @ASCO2020). Herein, we report secondary outcomes on the effects of the GA intervention on aging-related outcomes. Methods: Pts aged ≥ 70 with incurable solid tumors or lymphoma and ≥ 1 impaired GA domain starting a new treatment regimen were enrolled. Community oncology practices were randomized to intervention (oncologists received GA summary/recommendations) or usual care (none given). Secondary analyses examined effects of the intervention on functional outcomes (patient-reported falls, instrumental activities of daily living (IADL), short physical performance battery (SPPB), geriatric depression scale (GDS), and medications [total and prescription]). Outcomes were analyzed using linear mixed effects model, logistic or Poisson regression adjusted for baseline values, time, and site effects as appropriate. Results: From 2013-19, 718 pts were enrolled from 41 practices. Age (mean 77 yrs), sex (43% women), number of impaired GA domains (median 4/8), and treatment type (chemotherapy 88%) were not different by arm. More pts in intervention were black (12% vs 3%, p

12009 Background: GA evaluates aging-related domains (e.g., function) known to be associated with cancer treatment toxicity. In this CRCT, we evaluated if providing a GA summary with management recommendations to oncologists can reduce toxicity in older patients (pts) with advanced cancer receiving chemotherapy and/or other agents with a high reported prevalence of grade 3-5 toxicity. Methods: Pts aged > 70 with incurable solid tumors or lymphoma and > 1 impaired GA domain starting a new treatment regimen were enrolled. Community oncology practices were randomized to intervention (oncologists received GA summary/recommendations for impairments) or usual care (none given). The primary outcome was proportion of pts who experienced any grade 3-5 toxicity (CTCAE v.4) within 3 months. Practice staff prospectively captured toxicities; blinded oncology clinicians reviewed medical records to verify. Secondary outcomes included 6 month overall survival (OS) and treatment intensity (standard vs reduced). Outcomes were analyzed using generalized linear mixed/Cox models with Arm as a fixed effect, controlling for practice. Results: From 2013-19, 718 pts were enrolled from 41 practices. Age (mean 77 yrs), sex (43% women), number of impaired GA domains (median 4/8), and treatment type (chemotherapy 88%) were not different by Arm. More pts in intervention were Black (12% vs 3%, p

12099 Background: CIPN is a common dose-limiting side effect of taxane and platinum chemotherapy. It is difficult for clinicians to predict who will experience CIPN before initiating chemotherapy, partly because the etiology of CIPN is poorly understood. Specifically, although inflammation putatively plays a role in CIPN, there is limited evidence of the role of inflammation in CIPN in humans. Here, we identified the strongest predictors of CIPN using variables measured before taxane or platinum chemotherapy, including serum inflammation. Methods: 143 sedentary patients with cancer (81% breast, 7% colon, 5% lung; 7% other; mean age 56 years) receiving taxane or platinum chemotherapy rated the severity of (a) numbness and tingling, and (b) hot/coldness in hands/feet on 0-10 point scales before and after their first 6 weeks of chemotherapy. Linear regression models were fit to predict CIPN symptom severity at 6 weeks using variables related to inflammation (serum IL-1β, IL-6, IL-8, IL-10, IFN-γ, sTNFR1; 69 patients who gave blood), clinical factors (cancer stage, baseline neuropathy, fatigue, anxiety, depression, using diabetes medications), behavior (daily pedometer steps), and demographics (age, race) measured before chemotherapy. The final model was identified by the smallest AIC goodness of fit. Results: The strongest pre-chemotherapy predictors of numbness and tingling after 6 weeks of taxane and/or platinum chemotherapy were worse patient-reported fatigue/anxiety/depression (explaining 25% of variance), platinum chemotherapy (7%), and older age (5%). The strongest predictors of hot/coldness in hands/feet included worse baseline neuropathy (13%), platinum chemotherapy (8%), and fatigue/anxiety/depression (6%). In the 69 patients with serum data, a more pro-inflammatory state was a risk factor for CIPN as higher levels of pro-inflammatory IL-1β (7%) predicted numbness/tingling, and lower levels of anti-inflammatory IL-10 (7%) predicted hot/coldness in hands/feet. Conclusions: The strongest pre-chemotherapy predictors of CIPN included worse fatigue/anxiety/depression and platinum chemotherapy in this sedentary population of cancer patients (mostly breast). A pro-inflammatory state before chemotherapy may also increase risk for CIPN, suggesting that inflammation may underlie the etiology of CIPN in humans. Clinicians should consider assessing these factors to inform the patient’s risk for CIPN. Funding: NCI UG1CA189961, NCI K07 K07CA221931, T32CA102618. Clinical trial information: NCT00924651 .

Introduction: Inherited macrothrombocytopenias comprise a heterogeneous group of rare inherited disorders characterized by decreased platelet count with enlarged platelet size. Glycoprotein Ib (GP Ib) is a platelet surface membrane glycoprotein that is encoded by GP1BA gene, and functions as a receptor for von Willebrand factor (VWF). Mutations in the GP1BA gene are seen in Bernard-Soulier syndrome (BSS). Here we describe a family with an isolated giant platelet disorder and a novel variant in the GP1BA gene following an autosomal dominant mode of inheritance. In our kindred this variant was not associated with clinical history or specific laboratory evidence of BSS. Case Presentation: 34-year-old female reported first being diagnosed with macrothrombocytopenia at the age of 13 on routine blood work. The patient and 11 of her relatives spanning 5 generations have reported asymptomatic macrothrombocytopenia (Figure 1), described as "Magic Blood" by her family. Her platelet count fell below 20,000/microL during one of her pregnancies. She was treated as idiopathic thrombocytopenic purpura (ITP) and was given corticosteroids to increase platelet count without improvement. On presentation, patient's complete blood count was significant for low platelet at 55,000/microL and macrothrombocytes were observed on blood smear. Methods/Results: VWF assays, including Factor VIII activity, VWF Ag, and Ristocetin Cofactor, were within normal limits. VWF multimer analysis revealed a normal pattern and distribution of bands. Patient had a normal platelet aggregation in response to ADP, Collagen, Epinephrine, Ristocetin and Arachidonate. Flow Cytometry detected normal GP Ib and GP IIb/ IIIa expression. Whole exome sequencing and copy number analysis of 29 genes associated with thrombocytopenia revealed a c.97T>G substitution in the GP1BA gene predicted to result in the amino acid substitution p.Cys33Gly (Figure 2). To our knowledge, this variant has not been reported in the literature or public databases. To confirm this novel variant is the cause of the familiar macrothrombocytopenia, two relatives with macrothrombocytopenia, a maternal uncle and a first cousin, also underwent genetic testing and were found to have the same variant. Discussion: Variants in GP1BA are associated with both autosomal dominant and recessive forms of BSS and with autosomal dominant platelet-type VWD. Our kindred is surprisingly asymptomatic given the location and specific amino acid substitution generated by the variant. Amino acid residue p.Cys33 resides in an extracellular N-terminal domain that is critical for VWF binding and proper assembly of the GP1B-IX complex. A heterozygous substitution involving the same amino acid residue defined as p.Cys33Arg was observed in two patients with macrothrombocytopenia with no reported bleeding complications (MC, unpublished data). Substitution of a nearby cysteine residue defined as p.Cys20Gly has been reported in a case of monoallelic chronic macrothrombocytopenia without bleeding diathesis similar to our patient. Amino acid residues p.Cys20 and p.Cyc33 are highly conserved among divergent species and substitution of these amino acid residues appears to not be tolerated. Substitution of other cysteine amino acid residues in the extracellular domain of the GP1BA protein (p.Cys81 and p.Cys225) has also been reported in patients with biallelic BSS, suggesting that perturbation of cysteine amino acid residues is likely to affect protein structure and function. Conclusion:We think the p.Cys33Gly substitution found in our patient and her relatives is likely to be a primary cause of monoallelic GP1BA-associated macrothrombocytopenia. It is important to distinguish inherited macrothrombocytopenia from ITP in order to avoid unnecessary and potentially toxic treatment. Disclosures No relevant conflicts of interest to declare.

11544 Background: Older patients with advanced cancer face considerable uncertainty related to their disease and treatment. The aim of our study was to evaluate the associations of uncertainty with psychological status and QoL. Methods: This is a secondary analysis of baseline data from a national geriatric assessment (GA) cluster randomized trial (URCC 13070; PI: Mohile). Patients aged ≥70 years with ≥1 GA domain impairment (e.g., function, cognition) and advanced cancer who were considering or receiving any line of cancer treatment were enrolled (n=541). Uncertainty was measured using the modified 9-item Mishel Uncertainty in Illness (MUIS), where respondents with higher scores perceive more uncertainty (range 9-45). QoL and psychological measures consisted of Functional Assessment of Cancer Therapy-General (FACT-G), emotional wellbeing (EWB; FACT-G subscale), distress (distress thermometer), anxiety (Generalized Anxiety Disorder-7), and depression (Geriatric Depression Scale-15). Multiple linear regressions were used to evaluate the associations of MUIS scores with each measure, adjusted for demographics, cancer type, and number of impaired GA domains. Results: Mean age was 77 years (SD 5, range 70-96); 26% had gastrointestinal cancer and 26% had lung cancer. Mean number of GA domain impairments was 4 (SD 1, range 1-7). Mean MUIS score was 20 (SD 5, range 9-37). On multivariate analyses, higher MUIS score was associated with lower QoL (β=-1.08, SE=0.11) and EWB (β=-0.29, SE=0.03), as well as higher distress (β=0.12, SE=0.02), anxiety (β=0.11, SE=0.04), and depression (β=0.09, SE=0.03; all P

Severe (grade≥3) adverse events (AEs) to 5-fluorouracil (5-FU)-based chemotherapy regimens can result in treatment delays or cessation, and, in extreme cases, life-threatening complications. Current genetic biomarkers for 5-FU toxicity prediction, however, account for only a small proportion of toxic cases. In the current study, we assessed DPYD variants suggested to correlate with 5-FU toxicity, a deep intronic variant (c.1129-5923 C>G), and four variants within a haplotype (hapB3) in 1953 stage III colon cancer patients who received adjuvant FOLFOX±cetuximab. Logistic regression was used to assess multivariable associations between DPYD variant status and AEs common to 5-FU (5FU-AEs). In our study cohort, 1228 patients (62.9%) reported any grade≥3 AE (overall AE), with 638 patients (32.7%) reporting any grade≥3 5FU-AE. Only 32 of 78 (41.0%) patients carrying DPYD c.1129-5923 C>G and the completely linked hapB3 variants c.1236 C>G and c.959-51 T>C showed at least one grade≥3 5FU-AE, resulting in no statistically significant association (adjusted odds ratio=1.47, 95% confidence interval=0.90-2.43, P=0.1267). No significant associations were identified between c.1129-5923 C>G/hapB3 and overall grade≥3 AE rate. Our results suggest that c.1129-5923 C>G/hapB3 have limited predictive value for severe toxicity to 5-FU-based combination chemotherapy.

20 Background: Older patients with advanced cancer who are certain that they could be cured pose unique challenges for physicians who wish to help them prepare for death. By estimating the prevalence of absolute certainty about curability (ACC) and examining its correlates we aim to inform the development of interventions to improve end of life care. We hypothesized that patients who report greater willingness to bear adversity in exchange for longevity will be more likely to demonstrate ACC. Methods: This is a cross-sectional analysis of a nationwide geriatric assessment trial. Patients were asked: “What are the chances the cancer will go away and never come back with treatment [100% (ACC), > 50%, 50/50, < 50%, 0%, or unclear].” We assessed willingness to bear adversity using two types of trade-off questions. For trade-offs between treatment-related adverse reactions and survival, five statements on specific adverse reactions (nausea/vomiting, assistance with activities, bedbound state, confusion, worsening memory) were administered. For trade-off preferences between quality of life (QoL) and survival, patients answered the following statement: “Maintaining my QoL is more important to me than living longer”. Logistic regression was used to assess the independent associations of patient trade-off preferences with ACC, after controlling for covariates. Results: 349 older patients were included; 8.0% had ACC. 7.4% of respondents disagreed/strongly disagreed with the statement “Maintaining my QoL is more important than living longer.” Patients who were willing to trade QoL for survival were more likely to demonstrate ACC (AOR 4.43, 95% CI 1.13-17.42). Trade-off preferences between adverse reactions and survival were not associated with ACC. Non-white race, < high school education, lower household income, lack of social support, intact functional status, and no polypharmacy were associated with ACC (p < 0.05). Conclusions: Patients with advanced cancer who are more willing to accept a decreased QoL for survival are more likely to be certain that they will be cured. Beyond sharing prognosis, clinicians might help patients improve prognostic understanding by helping them identify and articulate their values and beliefs.

87 Background: Financial toxicity (FT), or the stress and strain patients (pts) experience as a result of paying for cancer care, can have profound negative impacts on pts’ overall quality of life (QoL). This study examined associations of FT with anxiety, depression, and QoL in older pts with advanced cancer. Methods: This is a secondary analysis of baseline data from a Geriatric Assessment intervention study conducted by UR NCORP across 31 practice sites (PI: Mohile). Pts were categorized as experiencing FT if they reported any one of the following: delaying medications due to cost, insufficient income in a typical month for food and housing, or insufficient income in a typical month for other basic needs. Pts also completed the Generalized Anxiety Disorder-7 (GAD7, score 0-21) to evaluate anxiety, the Geriatric Depression Scale (GDS, score 0-15) to assess depression, and the Functional Assessment of Cancer Therapy- Generation (FACT-G, score 0-108), to measure overall QoL. Associations of FT with anxiety, depression, and QoL were assessed in separate multivariate linear regression models controlling for covariates at p < 0.1. Results: Among 542 pts (mean age 77; range 70-96, 49% female), 18% (98 pts) experienced FT. In separate regression analysis, FT was significantly associated with all 3 outcome measures. On average, pts experiencing FT scored 1.76 higher (p < 0.01) on the GAD7 (indicating greater anxiety severity), 0.76 points higher (p = 0.02) on the GDS (indicating greater depression severity), and 5.16 points lower (p < 0.01) on the FACT-G (indicating lower QoL). Conclusions: Older pts with advanced cancer who experience income and cost-related barriers to quality cancer care reported worse anxiety, depression, and QoL than those without FT. Given the association between FT and these outcomes, these 3 FT questions may help identify vulnerable older pts and allow providers to intervene sooner and thereby enhance the quality of care pts receive.

BackgroundPrior studies with the use of a prospective–retrospective design including archival tumor samples have shown that gene-expression assays provide clinically useful prognostic information. However, a prospectively conducted study in a uniformly treated population provides the highest level of evidence supporting the clinical validity and usefulness of a biomarker. MethodsWe performed a prospective trial involving women with hormone-receptor–positive, human epidermal growth factor receptor type 2 (HER2)–negative, axillary node–negative breast cancer with tumors of 1.1 to 5.0 cm in the greatest dimension (or 0.6 to 1.0 cm in the greatest dimension and intermediate or high tumor grade) who met established guidelines for the consideration of adjuvant chemotherapy on the basis of clinicopathologic features. A reverse-transcriptase–polymerase-chain-reaction assay of 21 genes was performed on the paraffin-embedded tumor tissue, and the results were used to calculate a score indicating the risk of breast-...

Previous studies have suggested the potential importance of three DPYD variants (DPYD*2A, D949V, and I560S) with increased 5-FU toxicity. Their individual associations, however, in 5-FU-based combination therapies, remain controversial and require further systematic study in a large patient population receiving comparable treatment regimens with uniform clinical data.We genotyped 2886 stage III colon cancer patients treated adjuvantly in a randomized phase III trial with FOLFOX or FOLFIRI, alone or combined with cetuximab, and tested the individual associations between functionally deleterious DPYD variants and toxicity. Logistic regressions were used to assess univariate and multivariable associations. All statistical tests were two-sided.In 2594 patients with complete adverse event (AE) data, the incidence of grade 3 or greater 5FU-AEs in DPYD*2A, I560S, and D949V carriers were 22/25 (88.0%), 2/4 (50.0%), and 22/27 (81.5%), respectively. Statistically significant associations were identified between grade 3 or greater 5FU-AEs and both DPYD*2A (odds ratio [OR] = 15.21, 95% confidence interval [CI] = 4.54 to 50.96, P.001) and D949V (OR = 9.10, 95% CI = 3.43 to 24.10, P.001) variants. Statistical significance remained after adjusting for multiple variables. The DPYD*2A variant statistically significantly associated with the specific AEs nausea/vomiting (P = .007) and neutropenia (P.001), whereas D949V statistically significantly associated with dehydration (P = .02), diarrhea (P = .003), leukopenia (P = .002), neutropenia (P.001), and thrombocytopenia (P.001). Although two patients with I560S had grade≥3 5FU-AEs; a statistically significant association could not be demonstrated because of its low frequency (P = .48).In the largest study to date, statistically significant associations were found between DPYD variants (DPYD*2A and D949V) and increased incidence of grade 3 or greater 5FU-AEs in patients treated with adjuvant 5-FU-based combination chemotherapy.

KRAS and BRAF (V600E) mutations are important predictive and prognostic markers, respectively, in colon cancer, but little is known about patient and clinical factors associated with them.Two thousand three hundred twenty-six of 3397 patients in the N0147 phase III adjuvant trial for stage III colon cancer completed a patient questionnaire. Primary tumors were assessed for KRAS and BRAF (V600E) mutations and defective mismatch repair (dMMR) status. Logistic regression models and categorical data analysis were used to identify associations of patient and tumor characteristics with mutation status. All statistical tests were two-sided.KRAS (35%) and BRAF (V600E) (14%) mutations were nearly mutually exclusive. KRAS mutations were more likely to be present in patients without a family history of colon cancer and never smokers. Tumors with KRAS mutations were less likely to have dMMR (odds ratio [OR] = 0.21; 95% confidence interval [CI] = 0.15 to 0.31; P.001) and high-grade histology (OR = 0.73; 95% CI = 0.59 to 0.92; P.001) but were more often right-sided. Among KRAS-mutated tumors, those with a Gly13Asp mutation tended to have dMMR and high-grade histology. Tumors with BRAF (V600E) mutations were more likely to be seen in patients who were aged 70 years or older (OR = 3.33; 95% CI = 2.50 to 4.42; P.001) and current or former smokers (OR = 1.64; 95% CI = 1.26 to 2.14; P.001) but less likely in non-whites and men. Tumors with BRAF (V600E) mutations were more likely to be right-sided and to have four or more positive lymph nodes, high-grade histology, and dMMR.Specific patient and tumor characteristics are associated with KRAS and BRAF (V600E) mutations.

Background: Representation of diverse ethnic/racial groups is critically important in the development of cancer prevention and treatment strategies. However, representation of diverse ethnic/racial groups has yet to be fully realized, especially among historically disadvantaged minority groups. Ethnic minority groups account for about 75% of Hawai‘i’s population; approximately 55% of the state’s population self-identify as Asian (with the most predominant ethnic/racial groups being Japanese, Filipino, Chinese, and Korean) and approximately 24% as Native Hawaiian/Pacific Islander. Such diversity provided researchers a unique opportunity to characterize the demographic profile of cancer prevention and treatment trials conducted in Hawai ‘i. Methods: In the current study, the gender and ethnic/racial distribution of four national cancer prevention trials and 178 treatment trials conducted in Hawai‘i from 1992 to 2004 were characterized. Results: Native Hawaiian men were significantly less likely to participate in both cancer prevention and treatment trials than Native Hawaiian women. In addition, Native Hawaiian men and women had the lowest proportion of participation in cancer clinical trials in comparison to White and Asian American men and women. Conclusions: Our findings identify gender and ethnic/racial differences in the participation of cancer clinical trial participants in the state of Hawai‘i. This serves as an important indicator for the need of future research to specifically investigate the relationship of culture and other factors on participation. Such research may inform promotional strategies that increase trial participation, with the hopeful prospect of decreasing cancer incidence and increasing quality of life for those diagnosed with cancer.

BackgroundGiven the substantial improvements in cancer screening and cancer treatment in the United States, millions of adult cancer survivors live for years following their initial cancer diagnosis and treatment. However, latent side effects can occur and some symptoms can be alleviated or managed effectively via changes in lifestyle behaviors. ObjectiveThe purpose of this study was to test the effectiveness of a six-week Web-based multiple health behavior change program for adult survivors. MethodsParticipants (n=352) were recruited from oncology clinics, a tumor registry, as well as through online mechanisms, such as Facebook and the Association of Cancer Online Resources (ACOR). Cancer survivors were eligible if they had completed their primary cancer treatment from 4 weeks to 5 years before enrollment. Participants were randomly assigned to the Web-based program or a delayed-treatment control condition. ResultsIn total, 303 survivors completed the follow-up survey (six months after completion of the baseline survey) and participants in the Web-based intervention condition had significantly greater reductions in insomnia and greater increases in minutes per week of vigorous exercise and stretching compared to controls. There were no significant changes in fruit and vegetable consumption or other outcomes. ConclusionsThe Web-based intervention impacted insomnia and exercise; however, a majority of the sample met or exceeded national recommendations for health behaviors and were not suffering from depression or fatigue at baseline. Thus, the survivors were very healthy and well-adjusted upon entry and their ability to make substantial health behavior changes may have been limited. Future work is discussed, with emphasis placed on ways in which Web-based interventions can be more specifically analyzed for benefit, such as in regard to social networking.

Background Two arms with FOLFIRI, with or without cetuximab, were initially included in the randomized phase III intergroup clinical trial NCCTG (North Central Cancer Treatment Group) N0147. When other contemporary trials demonstrated no benefit to using irinotecan as adjuvant therapy, the FOLFIRI-containing arms were discontinued. We report the clinical outcomes for patients randomized to FOLFIRI with or without cetuximab. Patients and Methods After resection, patients were randomized to 12 biweekly cycles of FOLFIRI, with or without cetuximab. KRAS (Kirsten rat sarcoma viral oncogene homolog) mutation status was retrospectively determined in a central lab. The primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS) and toxicity. Results One hundred and six patients received FOLFIRI and 40 received FOLFIRI plus cetuximab. Median follow-up was 5.95 years (range, 0.1-7.0 years). The addition of cetuximab showed a trend toward improved DFS (hazard ratio [HR], 0.53; 95% CI, 0.26-1.1; P = .09) and OS (HR, 0.45; 95% CI, 0.17-1.16; P = .10) in the overall group, regardless of KRAS status, and in patients with wild type KRAS . Grade ≥ 3 nonhematologic adverse effects were significantly increased in the cetuximab versus FOLFIRI-alone arm (68% vs. 46%; P = .02). Adjuvant FOLFIRI resulted in a 3-year DFS less than that expected for FOLFOX. Conclusion In this small randomized subset of patients with resected stage III colon cancer, the addition of cetuximab to FOLFIRI was associated with a nonsignificant trend toward improved DFS and OS. Nevertheless, considering the limitations of this analysis, FOLFOX without the addition of a biologic agent remains the standard of care for adjuvant therapy in resected stage III colon cancer.

Background. The biochemical modulation of 5-fluorouracil (5-FU) by the reduced folate folinic acid (FA) in the treatment of patients with advanced gastric cancer was examined. Methods. The Southwest Oncology Group performed parallel randomized Phase II trials of two schedules of 5-FU and FA in 80 patients with advanced gastric cancer. Of 76 analyzable patients, 36 were randomized to receive bolus FA (200 mg/m 2 , days 1-4) along with continuous infusion 5-FU (1000 mg/m 2 , days 1-4) and 40 were randomized to receive bolus FA (200 mg/m 2 , days 1-5) before the bolus 5-FU (375 mg/m 2 , days 1-5). Results. There were three (8%) partial responses (95% confidence interval [CI] 2%-22%) on the continuous infusion arm. The bolus arm had two (5%) complete responses and six (15%) partial responses for an overall response rate of 20% (95% CI 9%-36%). The median duration of response was 4.6 months for the infusion patients and 16.6 months for the bolus patients. Survival was poor, with median survival of5 months on both regimens. Gastrointestinal toxicity was substantial, with Grade 3 mucositis observed in 36% of patients on the continuous infusion regimen versus only 10% of patients on the bolus regimen. Grade 3 or higher hematologic toxicity occurred more often in the bolus arm than in the continuous infusion arm (28% vs. 14%, respectively). Two toxic deaths occurred, one related to sepsis the other secondary to coronary insufficiency. Conclusions. Biochemical modulation of 5-FU by FA using the dose and schedules tested has only modest activity in the treatment of advanced gastric cancer

The Native Hawaiian population of Hawaii has disproportionately high cancer incidence and mortality rates. Native Hawaiian women with breast cancer present at an advanced stage and have death rates that are 52 % above the state average. Prostate cancer among Native Hawaiian men is diagnosed at more advanced stage. Native Hawaiian participation in cancer clinical trials was historically low. Reasons for this were varied including access, health literacy, lack of primary and referring physician awareness/time constraints and cultural barriers. Since the establishment of the University of Hawaii Minority Based Clinical Oncology Program (UHMBCCOP) participation in cancer clinical trials has definitely increased. MBCCOP provided clinical trial promotion, increased access and clinical trial support for a group of hospital and office based oncologists across the islands of Oahu and Kauai have all contributed to the increase. Education programs in Hawaii by multiple organizations, in particular, Imi Hale, the Native Hawaiian Cancer Network Program have enhanced knowledge of cancer and clinical trials in the Native Hawaiian community. Imi Hale's emphasis has focused on community based patient training, patient navigation and referring physician cancer clinical trial training. In fact, a recent program was recently initiated in conjunction with Education Network to Advance Clinical Trials (ENNACT) and Queens Medical Center. Review of Native Hawaiian participation in both cancer prevention and treatment trials through the UHMBCCOP over the last 20 years shows a significant gender difference with more women participating in both prevention and treatment trials. The reasons for this are not well understood but are under investigation. In summary, increased focused access and community based education have improved Native Hawaiian participation in cancer clinical trials but challenges persist including gender disparities in enrollment onto clinical trials and lack of access outside of Oahu and Kauai islands.

Purpose Hand-foot syndrome (HFS) is a dose-limiting toxicity of capecitabine for which no effective preventative treatment has been definitively demonstrated. This trial was conducted on the basis of preliminary data that a urea/lactic acid–based topical keratolytic agent (ULABTKA) may prevent HFS. Patients and Methods A randomized, double-blind phase III trial evaluated 137 patients receiving their first ever cycle of capecitabine at a dose of either 2,000 or 2,500 mg/m2 per day for 14 days. Patients were randomly assigned to a ULABTKA versus a placebo cream, which was applied to the hands and feet twice per day for 21 days after the start of capecitabine. Patients completed an HFS diary (HFSD) daily. HFS toxicity grade (Common Terminology Criteria for Adverse Events [CTCAE] v3.0) was also collected at baseline and at the end of each cycle. The primary end point was the incidence of moderate/severe HFS symptoms in the first treatment cycle, based on the patient-reported HFSD. Results The percentage of patients with moderate/severe HFS symptoms was not different between groups, being 13.6% in the ULABTKA arm and 10.2% in the placebo arm (P = .768 by Fisher's exact test). The odds ratio was 1.37 (95% CI, 0.37 to 5.76). Cycle 1 CTCAE skin toxicity was higher in the ULABTKA arm but not significantly so (33% v 27%; P = .82). No significant differences were observed in other toxicities between groups. Conclusion These data do not support the efficacy of a ULABTKA cream for preventing HFS symptoms in patients receiving capecitabine.

Background. Malignant mesothelioma is a highly treatment-resistant neoplasm. This study represents an attempt to define an effective form of systemic therapy. Methods. Twenty-six patients with unresectable diffuse malignant mesothelioma were enrolled in Southwest Oncology Group (SWOG) study 8731 and treated with ifosfamide, 2 g/m2 intravenously for 4 days, and mesna 2 g/m2 intravenously for 5 days, every 3 weeks. Patients were either previously untreated with chemotherapy or had at most one prior systemic treatment. Results. Two patients, or 8% (95% confidence interval, 1-25%), achieved partial response, with response durations of 4 and 6 months. One additional patient met criteria for tumor size reduction but not duration criteria. Thirteen (50%) patients had stable disease of 4 months' median duration (range, 1-13 months). The median survival of the entire group was 6.5 months. The dose-limiting toxicity was granulocytopenia (11 patients, ≤ 250/μl). Conclusions. Ifosfamide/mesna has modest activity in malignant mesothelioma. It could be tested using alternate dosage schedules and in combination with other agents in treating this highly resistant neoplasm.

508 Background: Severe adverse events (AEs) to 5-fluorouracil (5-FU) constitute a major dilemma in CC treatment. We recently demonstrated that specific deleterious DPYD variants in the coding region were highly predictive of grade >3 (G3+) AEs in stage III CC pts receiving adjuvant 5-FU based combination chemotherapy [Lee et al. JNCI. In press]. Other studies have suggested potential associations between AEs and non-coding DPYD variants: a novel haplotype (HapB3) containing three intronic variants (c.483+18 G>A, c.680+139 G>A, and c.959-51 T>C), one synonymous variant (c.1236 G>A, E412E), and a deep intronic variant (c.1129-5923 C>G) that affects pre-mRNA splicing. However, these studies included a diversity of cancer types, stages and treatments. The findings require further evaluation in a refined population. Methods: A total of 2,134 Caucasian stage III CC pts without DPYD*2A, D949V, and I560S variants from NCCTG N0147 trial who received adjuvant FOLFOX or FOLFIRI +/- cetuximab were genotyped by multiplexed single-base extension assays on the Sequenom MassARRAY. G3+ AEs were recorded (CTCAE v3) and classified as common to 5-FU treatment (5FU-AEs). Logistic regressions were used to assess the univariate and multivariate associations. Results: Analyzed pts displayed the following characteristics: 54.3% male, median age 59 [19-85], proficient MMR 87.5%, PS-0 76.5%, + irinotecan 8.5%, and + cetuximab 46.5%. Pts carrying c.1129-5923 C>G were significantly associated with higher risk of G3+ 5FU-AEs (Odds Ratio [OR]=1.539, 95% confidence interval [CI]=1.001 – 2.367, p=0.049). Only marginal association was observed for one of the HapB3 variants, c.1236 G>A (p=0.058). A linearly increasing risk of G3+ 5FU-AEs was identified for HapB3, comparing pts with no, one or >1 variant present (unadjusted OR=1.539, 95% CI=1.001 – 2.367, p=0.041; adjusted OR=1.198, 95% CI=0.998-1.437, p=0.052). Conclusions: In the largest study to date, c.1129-5923 C>G and HapB3 were predictive of 5FU-AE risk in stage III CC patients without DPYD*2A, D949V, and I560S variants receiving 5-FU-based combination chemotherapy.

A 36-year-old man with fever and pancytopenia due to Hemophagocytic Lymphohistiocytosis is reported. The patient was started on the HLH-94 based treatment. Two weeks after the initiation of therapy the patient's pancytopenia had resolved and he was discharged to complete treatment as an outpatient. The initial clinical presentation, diagnostic criteria, pathophysiology and treatment will be discussed.

Reactivation hepatitis B as a result of chemotherapy induced immunosuppression is well documented in the medical literature. Complications range from anicteric hepatitis to fulminant hepatic failure and death. Although lamivudine has been successfully used to treat hepatitis B reactivation in cancer patients, its role as prophylaxis in these patients is less well defined. We describe successfully lamivudine prophylaxis of a patient with chronic hepatitis B undergoing chemotherapy for acute myelogenous leukemia (AML). We support the position that lamivudine may play a significant role in the successful prevention of reactivation hepatitis B in cancer patients undergoing chemotherapy.

36 Background: Black race is associated with worse outcomes in localized breast cancer. We evaluated the characteristics of patients enrolled in the Trial Assigning Individualized Options for Treatment (TAILORx) by race and ethnicity. Methods: The analysis included 10,071 evaluable patients with Recurrence Score (RS) data. Eligibility criteria included: (1) T1-2, N0 disease, (2) estrogen receptor (ER) and/or progesterone receptor (PR) positive disease that was also HER2/neu negative, (3) age 75 years or younger and medically appropriate for adjuvant systemic chemotherapy. Results: The study population included 8,501 whites (84%), 722 blacks (7%), 423 Asians (4%), and the remainder other/unknown race. With regard to ethnicity, 7,916 were nonHispanic (79%), 919 were Hispanic (9%), and 1,236 were of unreported ethnicity (12%). There was no significant difference in RS distribution (p = 0.14), median RS (17 vs. 17), and mean RS (19.6 vs. 18.4) in blacks compared with nonblacks. There was likewise no difference in Hispanic vs. nonHispanic ethnicity for RS distribution (p = 0.53), median RS (17 vs. 17), and mean RS (18.6 vs. 18.4). Blacks were significantly more likely to be younger (39% vs. 30% < 50 years), have larger tumors (37% vs. 31% > 2 cm), poor histologic grade (25% vs. 17%), and PR-negative disease (14% vs. 10%) (Chi square test p < 0.05). Hispanic women were also significantly younger (39% vs. 30% < 50 years), and demonstrated marginal but statistically significant differences in tumor size (65% vs. 69% > 2 cm), histologic grade (20% vs. 18% poor), and PR expression (12% vs. 10% negative) (Chi square test < 0.05). In 974 patients with information on body mass index (BMI), there was no correlation between BMI and RS (r = -0.04). BMI was higher for blacks than whites (medians 31.6 vs. 28.9, p = 0.02, Wilcoxon test), but not in Hispanics. Conclusions: In patients selected for participation in TAILORx there were no significant differences in RS by race, ethnicity, and BMI. Black and Hispanic patients were significantly younger, and blacks had tumors that were larger and more likely to be associated with poor grade. Clinical trial information: NCT00310180.
