11569 Background: Kaposi sarcoma (KS) is the leading cancer in Malawi (34% of cancers). Outside of clinical trials, prospective KS studies from sub-Saharan Africa (SSA) are few and limited by loss to follow up. We conducted a prospective KS cohort study of standard of care bleomycin/vincristine (BV) at Lighthouse HIV clinic, in Lilongwe, Malawi. Methods: We enrolled pathologically confirmed, newly diagnosed, HIV+ KS patients from Feb 2017 to Jun 2019. We collected clinical and treatment characteristics, toxicity, and outcomes of KS with follow-up censored Jun 2020. Patients were treated with bleomycin (25 mg/m2) and vincristine (0.4 mg/m2) every 14 days for a planned maximum of 16 cycles. STATA v13.0 was used to calculate descriptive statistics and Kaplan Meier survival analysis. Toxicity was graded using NCI CTCAE v5.0. Results: We enrolled 138 participants, median age 36 (IQR 32-44) and 110 (80%) male. By ACTG staging, 107 (78%) were T1 (tumour severity), 46 (33%) were S1 (illness severity) and 46 (33%) had Karnofsky performance status ≤70. Presenting symptoms included edema in 69 (53%), visceral disease in 9 (7%), and oral involvement in 43 (33%). Prior to KS diagnosis, 70 (51%) participants were aware of being HIV+ for median 17 months (IQR 6-60) and had been on ART for median 16 months (IQR 6-60). Median CD4 count was 197 (IQR 99-339), median HIV-viral load was 2.6 log copies/mL (IQR 1.6 – 4.8) and 57% were HIV-suppressed ( < 1000 HIV copies/ml). The median number of cycles was 16 (IQR 7-16). 62 (45%) participants missed at least one dose due to stock out. Amongst patients with missed doses, the median number was 3 (IQR 2-4) for bleomycin and 2 (IQR 1-3) for vincristine. 14 (10%) participants experienced at least one reduced dose due to toxicity. 5 (4%) participants suffered grade ≥3 anaemia, 13 (9%) grade ≥3 neutropenia, and one participant had grade 4 bleomycin-induced dermatitis. There was no reported grade ≥3 bleomycin lung toxicity or vincristine-induced neuropathy. Of 115 evaluable participants, responses at the end of therapy were: complete response in 52 (45%), partial response in 27 (23%) stable disease in 5 (4%), and progressive disease in 31 (28%). Median duration of follow-up was 20 months. At censoring, 69 (50%) were alive, 36 (26%) dead, and 33 (24%) lost to follow-up. Overall survival is shown Table as crude and worst-case scenario; worst-case assumes all participants lost to follow up died. Conclusions: Here, we present one of the most complete characterizations of KS presentation and treatment from SSA. As in other studies from the region, the majority of patients presented with advanced disease, chemotherapy stock-outs and loss to follow up were common, and mortality was high. Studies are planned to understand the virologic characteristics, improve therapies, and better implement existing therapies.[Table: see text]

12001 Background: The COVID-19 pandemic has created conundrums for physicians. This study examines the experiences of oncologists who engage in complex decision-making regarding the use of chemotherapy in seriously ill persons in the context of the COVID-19 pandemic. Methods: Between January 2020 and August 2020, the authors conducted semi-structured, in-depth individual interviews with 22 purposefully sampled oncologists from practices enrolled in the Michigan Oncology Quality Consortium. Transcripts were double-coded and reconciled by consensus using qualitative data analysis software for thematic analysis. Results: Among the thematic clusters we identified, one was related to conundrums created by the COVID-19 pandemic. In this presentation, we report the results pertaining to three themes within this cluster: (1) the ethical dilemmas faced by oncologists due to the COVID-19 pandemic, (2) the need for both patients and oncologists to manage uncertainty and emotions, and (3) the importance and complexity of integrating technology and communication for seriously ill persons. Oncologists grappled with several conundrums including resource scarcity, resource allocation, delays in care, a duty to promote equity and non-abandonment, high levels of uncertainty and fear, and the importance of advanced care directives and end-of-life care planning. Non-abandonment featured as a coping mechanism for increased stress, and integration of communication with telemedicine was frequent and necessary. Conclusions: This study offers an in-depth exploration of the conundrums faced by oncologists due to the COVID-19 pandemic and how they navigated them. Optimal decision-making for seriously ill persons with cancer during the COVID-19 pandemic must include open acknowledgement of the ethical dilemmas faced, the heightened emotions experienced by both patients and their oncologists, and the urgent need for integrating technology with compassionate communication in determining patient preferences.

12002 Background: Falls are a major issue among older patients with cancer and can lead to interruption in cancer treatment. Ample evidence shows resistance and balance training can prevent falls in older adults; however, there is a paucity of evidence regarding exercise on fall prevention in the older cancer population, who often have unique risk factors for falls. Given the new reality of the COVID-19 pandemic, minimizing group gatherings and its associated risks is imperative for older patients, who are a vulnerable population. This study sought to investigate the feasibility of an 8-week, virtual exercise program and its preliminary effects on lower body strength and balance in community-dwelling cancer patients. Methods: Study participants were recruited for this pretest-posttest intervention study using consecutive sampling over a one-year period from the Cross Cancer Institute in Edmonton, Alberta. The intervention entailed leg muscle strengthening and balance training exercises that progressed in difficulty as outlined by the Otago program, and involved a virtual component (facilitated live by a certified exercise physiologist via Zoom meeting platform once a week) and independent at-home training component (twice a week). Lower body strength and balance were assessed using the 5-times chair-stand and the 4-stage balance test, respectively, and were analyzed using the Wilcoxon Signed Rank test. Results: Twenty-seven older patients (mean age 70.1, range 65-76) participated. The most common cancer sites were breast (48%) and prostate (41%). One participant withdrew due to personal reasons unrelated to the program. The remaining 26 participants completed the intervention. Attendance rate for the virtual component was 97.6% and independent component 84.7%. Participants perceived the program as rewarding and enjoyable (100%), felt this program prepared them to exercise on their own (92%), were confident to continue exercising on their own (81%), and would recommend the program to other patients (100%). At baseline, 33% (n = 9) ≥1 fall over the past 6 months. A statistically significant improvement in lower body strength was detected post-intervention ( p =.001), whereas no difference was detected in balance ( p =.059). Conclusions: This virtual, hybrid resistance and balance training program was feasible, overwhelmingly accepted by our older participants, and appeared effective in improving lower body strength. Findings from this study may have potential to inform design of a larger, randomized multi-site study.

12005 Background: Numerous pharmacogenetic studies have led to the identification of genetic polymorphisms associated not only with the development of cardiovascular disease, but also increase the risk of complications due to the use of anthracycline drugs, widely used in the treatment of cancer. The purpose of this study was to study the frequency of rs4673 and rs28714259 and possible associations with the risk of cardiovascular changes in patients with breast cancer during anthracycline therapy (anthracycline-mediated cardiotoxicity — AMC). Methods: The study included 256 Caucasian patients (median age - 55 years) with a diagnosis of breast cancer without diagnosed cardiovascular changes, who were treated with anthracyclines at the National Medical Research Center of Oncology in 2019-2020. For genotyping of rs4673 and rs28714259, DNA was extracted from blood using DNA-sorb-B (AmpliSens, Russia) and HRM-PCR was performed on a CFX96 amplifier (Bio-Rad, USA). The presence of polymorphisms was confirmed by Sanger sequencing on a Genetic Analyzer 3500 (ABI, USA). Results: During the follow-up period 21 (8.2%) patients were diagnosed with signs of subacute (changes developed within several weeks after the last course of therapy) or early chronic AMC (changes developed within a year after completion of anthracycline therapy). In the group of patients without AOC the allelic frequency of rs4673 (c.214T > C CYBA) was 0.38, the frequency of genotypes C/C – 0.4, C/T – 0.43, and T/T – 0.17. In the same group, the frequency of the A allele rs28714259 was 0.07, the frequency of the G/G genotypes – 0.87, G/A – 0.13, and A/A – 0. The prevalence of genotypes T/T rs4673 and allele G rs28714259 in a cohort of Russian patients differed from the European population (p = 0.014 and p = 0.05, respectively). The risk of cardiovascular changes on the background of anthracycline therapy increased in the presence of the rs4673 polymorphic allele by 6.49 times, in the case of the G/A and A/A rs28714259 genotypes - by 3.27 times. The results of the ROC-analysis suggested high quality of the tests based on the dominant models rs4673 and rs28714259 (AUC was 71.9% and 76.3% correspondingly). Conclusions: In this study the prognostic efficiency of the genetic markers rs4673 and rs28714259 was shown for the prompt detection of the risks of AMC development in the management of cancer patients. However, population characteristics should be taken into consideration for risk assessment.

12021 Background: Venous thromboembolism (VTE) is a well-known kind of cancer-associated thrombosis and a common complication of malignancy. However, little is known about the incidence of VTE and the effectiveness of direct oral anticoagulants (DOACs) associated with lung cancer chemotherapy. Methods: The Rising-VTE/NEJ037 study was a multicenter, prospective, observational study with 40 participating Japanese institutions. A total of 1,021 patients diagnosed with lung cancer that was unsuitable for radical resection or radiation were enrolled and followed up for two years. The diagnosis of VTE was confirmed through a central review by two radiologists. Patients with VTE at the time of lung cancer diagnosis started treatment with edoxaban. The primary endpoint of this trial was the rate of newly diagnosed VTE after enrollment or the recurrence rate 6 months after the start of treatment with edoxaban. Results: Of the 1,021 enrolled patients, data were available for 1,008 patients. The median age was 70 years (range: 30-94 years), and 70.8% were males. Eighty-six percent of patients had non-small cell lung cancer, and 13.6% had small cell lung cancer. Histological types included adenocarcinoma (N = 641, 63.6%), squamous cell carcinoma (N = 187, 18.6%), and others (N = 42, 4.2%). Sixty-two patients (6.2%) had VTE at the time of lung cancer diagnosis, and 42 patients (4.2%) developed VTE during two years follow-up, making a total of 104 patients (10.3%). No cases of VTE recurrence were found 6 months after the start of treatment with edoxaban. Major and minor bleeding occurred in 95 patients (9.4%) and increased to 23% in the edoxaban treatment group. The two-year survival probability was 0.43 in the non-VTE group and 0.48 in the VTE with edoxaban treatment group, showing no difference. Conclusions: This study shows a high cumulative incidence of VTE, suggesting that attention should be paid to VTE during treatment for lung cancer. Treatment with edoxaban was highly effective in preventing recurrence of VTE, and there was no difference in survival with or without VTE, but treatment should be considered more carefully because of the high bleeding rate associated with DOAC.

12025 Background: Follow-up care and surveillance in lung cancer survivors is essential formanagement of treatment- and disease-related symptoms as well as for the early detection of cancer recurrence. To investigate if race impacts receipt of follow-up care in lung cancer survivors, we conducted a cross-sectional study in lung cancer survivors recruited through the New Jersey State Cancer Registry (NJSCR). Methods: Between May 2019 and December 2019, survivors of early-stage NSCLC were identified and recruited from the NJSCR. Participants were eligible if they had surgery for stage I or II NSCLC between 2014 and 2017 and, completed all treatment at least one year prior to enrollment. Eligible participants were asked to complete a paper survey questionnaire and medical record release form sent to them by mail. The survey had questions about demographics, smoking, cancer history and treatment, quality of life, follow-up care, barriers to care and informational needs. Study measures were compared between the groups using t-test or chi-square test as applicable. Results: Of the 482 survivors contacted, 23% (n = 114) mailed back the survey questionnaire. Of the 112 survivors who returned a completed survey; 78 (70%) were non-Hispanic (NH) Whites and 34 (30%) were NH Blacks. Mean age was 67 years, 61% were female, 92% had cancer in remission. 82% of participants reported receiving a surveillance scan (CT or PET) within one year of completing the study survey. More NH White survivors received a scan within a year compared to NH Black survivors (89% vs 64%; p = 0.006). Also, 88% of survivors reported that they were informed of the need for follow-up care by their provider with more NH White survivors reporting receiving this information (94%) compared to NH Blacks (71%; p = 0.002). About 57% of the survivors reported receiving a written treatment summary and 92% reported being seen by a physician within the past year; no racial differences in these measures were noted.There was also no racial difference in receipt of age-appropriate cancer screening; 66% and 80% reported receiving regular colon and breast cancer screening, respectively. A significantly higher percentage of NH Blacks reported currently smoking compared to NH Whites (16% vs 12%). The most significant barriers to care for both populations were concern for out-of-pocket costs (26% NH Whites, 19% NH Blacks), non-coverage of test (14% NH Whites, 10% NH Blacks) and lack of insurance (8% NH Whites, 16% NH Blacks). Conclusions: Significant racial disparity was identified between NH Blacks and NH Whites in receipt of surveillance scans, guidance about follow-up care and smoking cessation. The most significant barriers to follow-up care was lack of insurance in NH Blacks and financial concerns about cost and coverage of tests in NH Whites. Future interventions to increase survivorship care should target these specific needs in survivor populations.

12045 Background: Preservation of functional independence while undergoing treatment is of utmost importance to older adults with cancer, in addition to being associated with healthcare utilization and survival. Yet, such data are not readily available from published clinical trials. We sought to examine functional status trajectories and risk factors associated with functional decline among older adults receiving treatment for GI malignancies. Methods: This study included older adults (≥60y) treated at the UAB GI oncology clinic and enrolled in a prospective Cancer and Aging Resilience Evaluation (CARE) registry. All patients completed a geriatric assessment (GA) that included an assessment of activities of daily living (ADL) and instrumental activities of daily living (IADL). Participants were approached for a repeat assessment three months after baseline GA. Change in functional status was classified as one or more points decline or improvement in IADL and/or ADL from baseline to follow up. We measured the proportion with functional decline or improvement and constructed 95% confidence interval (95%CI) using binomial exact methods. We built multivariable logistic regression models to study the impact of baseline predictors on functional decline. Putative risk factors included age, sex, race/ethnicity, cancer type & stage, baseline CARE frailty index, fatigue, pain, malnutrition and CT-based muscle mass indices (Skeletal Muscle Index [SMI] and Skeletal Muscle Density [SMD]) at the time of diagnosis. Results: This study included 184 patients. The median age at first visit was 68y (IQR 64-74); 55% were males, 71% white. Primary cancer diagnoses included colorectal cancer (29%), pancreatic cancer (28%) and other GI cancers (43%); 73% presented with advanced stage disease (III/IV). Most patients were receiving first line therapy (91%), with systemic chemotherapy (95%). The median duration between the baseline and follow up assessment was 109 days (IQR 84-154 days). Overall, 38% (95%CI, 30-45%) experienced a functional decline, whereas functional improvement was seen in 22% (95%CI, 16-29%). In a multivariable analysis, baseline frailty (odds ratio [OR] = 2.37; 95%CI, 1.05-5.38; p =0.03) was associated with significantly increased odds of functional decline; a trend towards increased odds was seen for pancreatic cancer (OR = 2.23; 95%CI, 0.90-5.53; p= 0.08; reference group: colorectal cancer). Conclusions: One in three older adults with GI malignancies experienced functional decline while a quarter experienced functional improvement in the first 3 months following treatment. Baseline frailty was associated with higher odds of functional decline. Early identification of such patients may allow targeted interventions to preserve functional independence and optimize quality of life of older adults with cancer.

12049 Background: Prior studies suggest that social support plays a role in disease understanding of older patients with advanced cancer. In this study, we examined the association of quantity and quality of social support with belief in curability among older patients with advanced incurable cancer. Methods: We performed a secondary analysis of a cluster-randomized geriatric assessment trial (URCC 13070: PI Mohile) that recruited older adults (≥70) with advanced incurable cancer and caregivers. At enrollment, patients completed the Older Americans Resources and Services (OARS) Medical Social Support form to measure both quantity (number of close friends and relatives) and quality of social support. Quality of social support was measured using twelve questions, each ranged from 1 (none of the time) to 5 (all of the time). Higher cumulative scores indicated greater quality of support. For beliefs in curability, patients were asked, “What do you believe are the chances that your cancer will go away and never come back with treatment?” Responses were 0%, <50%, 50/50, >50%, and 100%. Ordinal logistic regression was used to investigate the association of social support with beliefs in curability, adjusting for adjusting for age, gender, education, race, number of Geriatric Assessment (GA) impairments, cancer type, and locality (rural versus urban). Results: We included 347 patients; mean age was 76.4 years, 91% were white, 52% were male, 46% had household income <$50,000, and 55% had high school degree or higher. For every unit increase in OARS Medical Social Support score, the odds of believing in curability decreases by 36.4% [Adjusted Odds Ratio (AOR) 0.733, 95% Confidence Interval (CI): (0.555, 0.969)], after controlling for covariates. Quantity of social support was not associated with belief in curability [AOR 1.033 95% CI: (0.921, 1.156)]. Conclusions: Our study revealed that older patients with advanced cancer who felt more supported by their social network were more likely to report that their cancer was not curable. Interventions that improve quality of social support may also affect disease understanding.
