Efficacy and tolerability of fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) in unselected patients with advanced gastric and gastroesophageal cancer: does age really matter?

Abstract

Fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) regimen has shown strong efficacy as perioperative therapy for patients with locally advanced gastric (GC) and gastroesophageal (AEG) carcinoma. In the palliative situation, FLOT is recommended only for young fit patients. Data of efficacy and tolerability of FLOT in elderly patients are scarce and controversial. Thus, this study aimed to provide real-life experience of elderly patients with GC and AEG treated with FLOT as first-line palliative chemotherapy. Patients with advanced or metastatic GC or AEG and treated with FLOT as first-line palliative therapy between 2010 and 2021 were analyzed. Patients were grouped into < 65 years old (n = 35) and ≥ 65 years old (n = 22) groups. Overall survival (OS), progression-free survival (PFS), feasibility and toxicity were analyzed. The median OS was 10.4months with no significant difference between both groups (HR 0.86; 95% CI 0.48, 1.57; p = 0.632). The ECOG performance status showed powerful influence on OS in the subgroup analysis with median OS of 12.3months for ECOG = 0 compared to 5.0months for ECOG ≥ 1 (p = 0.015) as well as in multivariate analysis (HR 2.62; 95% CI 1.36, 5.04; p = 0.004). In the present study the ECOG performance status showed a stronger prognostic value than patient age in FLOT as first- line therapy in a real-life cohort with advanced and metastatic GC and AEG. The performance status should therefore be considered in the therapeutic decision making of elderly patients with GC and AEG.
