Robotic gastrectomy is safe in geriatric patients with gastric cancer: a retrospective cohort study.

Abstract

The efficacy of robotic surgery in oncological operations has been demonstrated, but its applicability in the elderly population (≥70 years) is limited in studies. This study aims to investigate the feasibility, safety, and short-term outcomes of robotic surgery in gastric cancer surgery in geriatric patients. Patients who underwent robotic surgery for gastric cancer between July 2021 and September 2023 were included in the study. Patients were divided into two groups: the elderly group (≥70 years) and the younger group (<70 years). Demographic data, clinical findings, perioperative outcomes, and pathology results were analyzed and compared between the two groups. 63 patients were included in our study. Group 1, the younger patients (<70 years), consisted of 44 patients, while Group 2, the older patients (>70 years), consisted of 19 patients. The male gender was dominant in both groups (70.5% vs. 78.9%, p=0.486). ASA 2 was the most common score in both groups (70.5% vs. 52.6%, p=0.261). Group 2 had lower hemoglobin (11.3 vs. 10.1, p=0.017) and albumin levels (39.9 vs. 37.6, p=0.049). The average operation times were similar in both groups (255 min vs. 242 min, p=0.457). The median postoperative hospital stay was 5 days in both groups. The distributions of postoperative complications according to the Clavien-Dindo classification were similar. Postoperative 30-day mortality was observed in one patient in Group 2. The 90-day hospital readmission rates were similar (11.3% vs. 10.6%, p=0.459). The average tumor diameters were similar (38 mm vs. 48 mm, p=0.165), as were the numbers of dissected lymph nodes (35 vs. 34, p=0.796). According to pathology results, T4a tumors were most common in Group 1 and T0 tumors in Group 2 (34.1% vs. 31.6%, p=0.149). The most common lymph node involvements were N0 in Group 1 and N1 in Group 2 (36.4% vs. 36.8%, p=0.515). Robotic surgery in gastric cancer is considered a safe and feasible method in the elderly population due to its successful early outcomes, suggesting its reliability and effectiveness.
