Background: The treatment strategy for patients with resectable gastric cancer changed in the last few years with perioperative treatments. FLOT regimen (fluorouracil, oxaliplatin, docetaxel) turned out to be feasible and effective, offering significant improvement in survival outcomes. However, the safety profile of triplet therapies for elderly patients deserves a special attention and, consequently, the best treatment strategy for these patients is still debated. Methods: Focusing on the elderly patient population (age ≥65 years), real-world data from patients with resectable gastric or gastro-oesophageal junction (GEJ) adenocarcinoma (T≥2 and/or N+) enrolled in the observational RealFLOT study were collected. Results: A total of 206 patients with resectable gastric or GEJ adenocarcinoma received perioperative FLOT at 15 Italian centers in routine clinical practice, between September 2016 and September 2019. The median age was 63 years (range 36-77) and 43% of patients enrolled (n = 89) were ≥65 years. Among elderly patients, 46 (52%) received FLOT for at least 4 full-dose cycles in the preoperative phase, 82 (92%) underwent surgery, and 56 (62%) started the postoperative phase. The primary end point of the study, pathological complete response (pCR) rate, was similar among patients aged ≥65 and < 65 (6.7% vs 7.7%, respectively). The distribution of pathological stages did not differ according to age (p = 0.473), and disease-free survival (DFS) is unrelated to the age of patients (log-rank 0.57; p = 0.89). The incidence of grade (G) 3-4 adverse events (AEs) was similar in the two age groups (Table) and the 30-day mortality rates after surgery did not differ according to age. Conclusions: FLOT regimen demonstrated to be feasible and safe in elderly patients since no differences were observed in terms of pCR, DFS and safety profile according to age.
