作者对94例胃癌(Ⅰ期1例,Ⅱ期20例,Ⅲ期46例,Ⅳ期27例,病理类型主要为未分化癌、低分化癌和腺癌),行扩大根治术(R_2~+式),选择性切除部分第3站淋巴结,全组3、5年生存率高于50％和45％。Ⅰ、Ⅱ、Ⅲ3期之3、5年生存率高于69％和61％。认为对Ⅱ、Ⅲ期胃癌应采用R_2~+术,对Ⅳ期不宜强行本术。胃癌切除加脐静脉置管化疗对减少肝转移、提高5年生存率有所益,值得进一步应用观察。
The authors underwent extended radical resection in 94 cases of gastric cancer (1 in stage I, 20 in stage II, 46 in stage III, 27 in stage IV, and the pathological types are mainly undifferentiated carcinoma, poorly differentiated carcinoma, and adenocarcinoma) (R_2~+ (Formula) Selective removal of part of the 3rd station lymph nodes, the whole group 3, 5 years survival rate is higher than 50% and 45%. The 3-year and 5-year survival rates of phase I, II, and III3 were higher than 69% and 61%. It is considered that R_2~+ surgery should be used for stage II and III gastric cancer. Resection of gastric cancer plus umbilical vein catheter chemotherapy is beneficial to reduce liver metastasis and improve 5-year survival rate, and it is worth further observation.
