389 Background: Pancreatic cancer (PCa) is more frequent in older adults, but older patients are underrepresented in large clinical trials. There is limited data on efficacy and safety of regimens such as FOLFIRINOX or nab-paclitaxel/gemcitabine (nab-gem) in older adults, especially Hispanics. Therefore, we compared the efficacy and safety of first-line PCa regimens in older adults. Methods: Retrospective analysis of stage IV PCa at our Hispanic-majority NCI-designated cancer center from 2000-2017. mPFS and mOS estimated from KM curves and groups were statistically compared with the log-rank test. The magnitude of association between dichotomous factors and survival was estimated with the hazard ratio (HR). Results: Forty-eight pts, mean age 71.7 years, median 69.2 (range 65-90). 31% Hispanic; 50% Male. First-line treatment: FOLFIRINOX (n=9), nab-gem (n=11), gem (n=11), other (n=9), supportive care (n=2). Baseline ECOG 0-1: 100%, 94%, 45%, 100%, 1% (p=0.004). Baseline albumin: 3.4, 3.4, 3.1, 3.5, 2.25 (p=0.06). mOS 7.1 months (95% CI 5.9-10.1). mPFS 5.6 months (95% CI: 5.3-NR). mOS by group: 8.6 mo, 7.1 mo, 3.2 mo, 2.9 mo, not available (p=0.95). Most patients had grade 0-2 toxicities (See table). Grade 3-4: fatigue n=2, neutropenia n=1, neuropathy n=1, mucositis n=1. Conclusions: Combination systemic chemotherapy are tolerated in older adults with PCa; however, in our cohort, survival was lower than historic phase 3 clinical trials with these regimens. Patients receive 2+ drugs had higher ECOG and albumin at baseline. Prospective studies with geriatric assessments are needed to determine patients who benefit from combination chemotherapy.
