Background: Outside of clinical trials, real-world data of advanced gastric cancers (AGCs) managed with perioperative or adjuvant chemotherapy with a backbone of D2 lymphadenectomy is limited.

Patients And Methods: Curative resections for gastric adenocarcinoma between January 2003 and January 2020 at the Tata Memorial Centre were analyzed, comparing three time periods marking major increments in annual gastric resections (GRs).

Results: 1657 radical gastric resections were performed with a morbidity and mortality rate of 34.
