BACKGROUND: Gastric cancer (GC) patients with advanced age and/or multiple morbidities have limited expected survival and may not benefit from extended lymph node resection. The aim of this study was to evaluate the surgical outcomes of these GC patients who underwent gastrectomy with D1 dissection. METHODS: We retrospectively reviewed all GC patients who underwent gastrectomy with curative intent from 2009 to 2017. The decision to perform D1 was based on preoperative multidisciplinary meeting, and/or intraoperative clinical judgment. RESULTS: Among 460 enrolled patients, 73 (15.9%) underwent D1 lymphadenectomy and 387 (84.1%) D2 lymphadenectomy. Male gender, older age, American Society of Anesthesiologists score (ASA) III/IV, higher neutrophil-to-lymphocyte ratio (NLR) and higher Charlson Comorbidity Index (CCI) were more common in the D1 group. Postoperative major complications were significantly higher in D1 group (24.7% vs 12.4%, p < 0.001) and mostly related to clinical complications. Locoregional recurrence was higher in the D1 group (53.8% vs 39.5%, p = 0.330) however, without statistical significance. No difference was found in disease-free survival (DFS) between D1 and D2 patients with positive lymph nodes (p = 0.192), whereas overall survival was longer in the D2 group (p < 0.001). Multivariate analysis showed a statistically significant impact on survival of age ≥70 years, CCI ≥5, total gastrectomy, D1 lymphadenectomy and advanced stages (III/IV). CONCLUSIONS: Frail patients had high surgical mortality even when submitted to D1 dissection. DFS was comparable to D2. Extent of lymphadenectomy in high-risk patients should take in account the expectation of a decrease in surgical risk with the possibility of impairment of long-term survival.
