dc.description.abstract | Background: In Western countries, the current standard of care for resectable gastric cancer is periop CT. There is much interest in preop CRT, but comparison to periop CT alone is lacking. In TOPGEAR we hypothesized that adding preop CRT to periop CT would improve pathological complete response (pCR) rates and ultimately overall survival (OS) compared to periop CT alone. Method(s): This international phase 3 trial randomized patients with resectable adenocarcinoma of the stomach and gastro-esophageal junction to periop CT alone, or with preop CRT. The periop CT alone group received 3 cycles of epirubicin/cisplatin/5-fluorouracil (ECF) or 4 cycles of fluorouracil/leucovorin/oxaliplatin/docetaxel (FLOT) both pre- and post-operatively. The preop CRT group received one less cycle of preop chemotherapy followed by chemoradiotherapy (45 Gy in 25 fractions radiation plus infusional 5-FU ), and then the same postop chemotherapy. The primary endpoint was overall survival, and secondary endpoints included progression free survival (PFS), pCR rates, toxicity and quality of life. Result(s): Between September 2009 and May 2021, 574 patients were enrolled from 70 sites across 15 countries in Australasia, Europe, and Canada; 288 to periop CT group and 286 to preop CRT group. Compared to periop CT alone, patients receiving preop CRT achieved a higher pCR rate (16.7% vs 8.0%), a higher rate of major pathological response (0 - <10% residual tumor: 49.5% vs 29.3%), and greater tumor downstaging following resection. After a median follow-up of 66.7 months, there was no significant difference in OS or PFS: median OS periop CT 49.4 months vs preop CRT 46.4 months; median PFS periop CT 31.8 months vs preop CRT 31.4 months. Preop CRT was not associated with increased perioperative treatment toxicity or a higher rate of surgical complications. Conclusion(s): Despite improving pathological outcomes, the addition of preop CRT to periop CT does not improve overall survival compared to periop CT alone in patients with resectable gastric and gastro-esophageal junction adenocarcinoma.
