Aim  Survival outcomes in elderly patients with pathological stages (pStages) II and III gastric cancer remain inadequately elucidated. We retrospectively analyzed outcomes of elderly and nonelderly patients who underwent curative gastrectomy for this cancer and considered clinical results of the Estimation of Physiologic Ability and Surgical Stress (E‐PASS) scoring system for prediction.    Methods  Among 1041 patients who underwent gastrectomy for pStages II and III gastric cancer between 2008 and 2013 consecutively, 898 patients were enrolled. Of these, 158 patients (17.6%) were elderly and 740 patients (82.4%) were nonelderly.    Results  Disease‐specific survival (DSS) in the elderly group with pStage III cancer was significantly worse than that in the same stage nonelderly group ( P  = .001), while there was no difference in DSS for pStage II cancer between the groups ( P  = .45). Overall survival (OS) was significantly worse in elderly patients for both pStages II and III. Elderly patients with pStage II cancer had larger survival gaps between OS and DSS compared with those with pStage III cancer. OS for elderly patients with comprehensive risk score (CRS) > 0.159 was significantly worse than that for elderly patients with CRS ≤ 0.159 in pStage II cancer.    Conclusions  Compared with nonelderly patients, different characteristics were observed in the survival outcomes of elderly patients between pStages II and III gastric cancer. The survival gap between OS and DSS of elderly patients was larger in pStage II cancer than in pStage III cancer. The E‐PASS scoring system could be a relatively useful predictor in elderly patients.
