Abstract
300 Background: Perioperative treatments have significantly improved survival in patients with resectable gastric cancer, increasing 5-year overall survival from 23% with surgery alone to 45% with FLOT (fluorouracil, oxaliplatin, docetaxel). Pathological regression is a prognostic marker of better survival. Methods: In this observational, retro- and prospective study we collected data from patients with resectable gastric or gastro-oesophageal junction (GEJ) adenocarcinoma treated, as clinical practice, with perioperative FLOT. All patients had clinical T2 or higher and/or nodal involvement, according to FLOT4-AIO trial. Results: A total of 206 patients received perioperative chemotherapy with FLOT at 15 Italian centres, between September 2016 and September 2019. Overall, 186 (90.3%) patients completed the preoperative phase, 190 (92%) underwent surgery, and 142 (68.9%) started the postoperative phase. Among patients who started the postoperative phase, 105 (51.0%) received FLOT, while 37 (18%) received less intensive regimens (e.g. FOLFOX or De Gramont), depending on performance status after surgery or toxicity in the preoperative phase. Pathological complete response (pCR) was obtained in 7.3% of cases. In the preoperative phase, grade (G) 3-4 hematological and gastrointestinal adverse events (AEs) were reported in 42 (20.4%) and 13 (6.3%) patients, respectively. Conclusions: These real data confirmed the feasibility of perioperative FLOT in a less-selected population, representative of the clinical practice. The pCR rate was lower than in the FLOT4-AIO trial. The survival outcomes, potential predictive or prognostic factors and comprehensive safety data will be included in the final analysis.
