    Abstract:
    BACKGROUND/AIM: Elderly patients with pathological stage II/III gastric cancer struggle to complete adjuvant chemotherapy. Neoadjuvant chemotherapy (NAC) for treating locally advanced gastric cancer (LAGC) has drawn attention; however, its indication for elderly patients who are vulnerable to chemotherapy is unclear. This study aimed to investigate the feasibility and efficacy of NAC for elderly patients with gastric cancer. PATIENTS AND METHODS: In this study, patients aged ≥75 years who underwent curative gastrectomy for LAGC or adenocarcinoma of the esophagogastric junction between April 2013 and November 2021 were included. Vulnerable patients, with poor Eastern Cooperative Oncology Group Performance Status (ECOG-PS) of 2-3 were also included. The patients were classified into NAC+ (n=20) and NAC - (n=45) groups. The clinicopathological data of the patients were retrospectively investigated. RESULTS: The NAC+ group showed a higher R0 resection rate than the NAC- group (100% vs. 89.1%, p=0.3) and pathological downstaging was achieved in 12 (60%) cases, including five (25%) pathological complete responses. The incidence of adverse events during postoperative chemotherapy was 35%, and the rate of postoperative complications greater than Clavien-Dindo Grade II was comparable between the two groups (35% vs. 46.7%, p=0.43). The NAC+ group showed a higher three-year overall survival rate (75% vs. 36%, p=0.015). CONCLUSION: NAC was feasible and effective for elderly patients including vulnerable patients with LAGC or adenocarcinoma of the esophagogastric junction. It can be considered as treatment option, with a high down staging rate and better survival.
