小胃癌及微小胃癌的诊断治疗:附28例报告

Diagnosis and treatment of minute and small early gastric cancer:a report of 28 cases

目的 探讨小胃癌及微小胃癌的诊断、治疗方法及病理特点。方法 对近 1 0年收治的2 8例小胃癌及微小胃癌的临床病理资料及诊断治疗方法进行回顾性分析。结果 本组微小胃癌 1 0例 ,小胃癌 1 8例 ,占同期早期胃癌手术病例的 34 .6 %。其中上消化道造影检出率为 8.3 % ,胃镜检查加活检的检出率为 78.8%。病灶均位于胃体和胃窦部。行胃癌D1根治术 6例 ,D2术 2 2例。小胃癌组的浸润深度显著深于微小胃癌组 (P <0 .0 5)。微小胃癌组无胃周淋巴结转移 ,小胃癌组淋巴结转移 2例 (1 1 .1 % )。术后 5年总生存率为 92 .9% ,其中微小胃癌组为 1 0 0 % ,小胃癌组为85.7%。结论 小胃癌及微小胃癌在早期胃癌中所占比例 >1 /3。胃镜检查加活检是诊断小胃癌及微小胃癌的主要手段 ,根治术后 5年生存率高 ,预后较好。

Objective To investigate the diagnosis,treatment and pathological characteristics of minute and small early gastric cancer(M EGC and S EGC).Methods The clinical and pathological parameters,and the diagnosis and treatment of 28 patients with M EGC or S EGC admitted to our hospital in recent 10 years were analysed retrospectively.Results There were 10 patients (12.4%) with M EGC,18( 22.2 %)with S EGC,and the proportion of M and S EGC in early GC is 34.6%.The diagnosis rate of gastric barium examination was 8.3% and that of gastroscopy with biopsy was 78.8%.All the carcinomas located in the body and antrum of the stomach.D1 radical gastrectomy(RGC) was performed on 6 patients and D2 RGC on the other 22 patients.The depth of tumor invasion in S EGC was significantly deeper than that in M EGC(P<0.05).None of the M EGC patients had perigastric lymph node metastasis but 2 of 18( 11.1 %) S EGC patients had lymph node metastasis.The 5 year survival rate in this series was 92.9%,with 100% in M EGC,and 85.7% in S EGC. Conclusions The proportion of M EGC and S EGC out of early gastric cancer is higher than 30%.Gastroscopy plus biopsy is the main diagnostic method;radical gastrectomy has high 5 year survival rate.
