Objective To investigate the effects of radical gastrectomy for the treatment of gastric carcinoma． Methods 175 cases of gastric carcinoma undergoing radical gastrectomy in our hospital from 1993 to 1999 were analyzed retrospectively. Results There were 16 cases (9.1%) with early stage, and 159 cases (90.9%) with advanced stage. 122 cases underwent D2 resection, and 53 cases with extended lymph node dissection. The absolute curative rate were 59.8% (73/122) and 83% (44/53) respectively． The total five year′s survival rate was 30.5% (21/69)． The five years survival rate of absolute radical resection was 36.3%(16/44), and that of relative radical resection was 20% (5/25)． The five year′s survival rate of the patients receiving absolute radical resection, including No.16 lymph node dissection was 41.7%(5/12). Conclusions It was reasonable and necessary to perform extended lymph node dissection with the clearance of No.16 lymph node in selected patients with advanced gastric carcinoma%目的 提高进展期胃癌手术治愈率。 方法 回顾性分析1993～1998年间我院施行的胃癌根治术175例。 结果 早期胃癌16例（9.1％），进展期胃癌159例（90.9％）。D2术患者122例。绝对根治率（淋巴结清扫范围大于淋巴结转移范围）59.8％（73/122），包括No.16在内的扩大淋巴清扫术患者53例，绝对根治率83％（44/53）。总体5年生存率30.5％（21/69）。绝对根治术5年生存率36.3％（16/44），相对根治术（淋巴结清扫范围内有转移）5年生存率20％（5/25）。包括No.16清扫术在内的绝对根治患者5年生存率41.7％（5/12）。 结论 有选择性的施行包括No.16在内的扩大淋巴结清扫对提高进展期胃癌生存率是合理和必要的。
