BACKGROUND: Locally advanced gastric adenocarcinomas are treated with neoadjuvant chemotherapy, surgery, and adjuvant chemotherapy. Since 2019 the standard of care for perioperative chemotherapy has been FLOT protocol. Concerns regarding the use of FLOT in elderly patients ≥ 65 years of age emerged due to the relatively high toxicity of this protocol.
OBJECTIVES: To evaluate the toxicity profile of FLOT and clinical outcome in elderly patients.
METHODS: We conducted a retrospective analysis of patients with locally advanced gastric adenocarcinomas treated with FLOT between 2017-2023 at the Sheba Medical Center. The cohort was stratified by age (≥ or < 65 years). The primary outcome was overall survival (OS). Secondary outcomes were treatment-related toxicity. Kaplan-Meier analysis and Cox proportional hazard regression model were used to analyze the effect of exposure variables on OS.
RESULTS: The study cohort included 91 patients. The median age was 60 years (IQR 50-67); 32 patients were included in the ≥ 65 years group, and 59 patients were included in the < 65 years group. Median follow-up was 40 months (IQR 17-58). Patients ≥ 65 years old received fewer cycles of FLOT compared to those < 65 years old (4.5 vs. 7 cycles, respectively, P = 0.03). Despite the difference in treatment intensity and cumulative chemotherapy dose, there was no difference in median OS between patients ≥ 65 years old compared with those < 65 years old (P = 0.68).
CONCLUSIONS: Elderly patients with locally advanced gastric adenocarcinomas received fewer cycles of perioperative FLOT without compromising clinical outcomes.
