Background: There is no consensus in the influence of NO.10 lymph node(LN) dissection for advanced gastric cancer(AGC) patients. We aimed to evaluate whether AGC patients could benefit from NO.10 LN dissection and the clinicalpathological indicators of NO.10 LN metastasis.Methods: We analyzed data on 218 patients with AGC patients who had underwent standard D2 lymphadenectomy(n=108) or modified D2 lymphadenectomy(n=110) from January 2017 to January 2021. Additionally, we also examined the influencing factors of NO.10 lymph node metastasis in the SD2 group.Results: The differentiation, tumor size and NO.4 positive LN were significantly correlated with the NO.10 LN metastasis(P<0.05). The Borrmann’s classification, differentiation, depth of invasion, lymph node metastasis (N), and tumor size were found to correlate with survival on univariate analyses. The age, gender, extent of gastrectomy, tumor location and lymphadenectomy extent were not related to survival(P>0.05). The median survival time was 72.23 months and 68.56 months for the SD2 and MD2 groups, respectively(P=0.635). Postoperative major morbidity and mortality rates were 37.96% and 3.70% in the SD2 group, and 23.64% and 1.82% in the MD2 group, respectively.Conclusions: The prophylactic NO.10 lymphadenectomy may be recommended in AGC patients with positive NO.4 LN, poor differentiation and tumor located on the greater curvature.
