根治性胃癌手术五年生存率约在40%,治疗失败主要原因是沿胃左动脉、肝动脉、腹腔动脉干周围的淋巴结转移率高,且手术很难根除血管周围的癌巢。即认为是根治手术,但手术区组织内仍可残留癌瘤。放射治疗对胃癌的作用不大,且胃区的外照射可引起小肠的损伤,因而限制完成全量的放射治疗。为提高胃癌的治愈率,
The five-year survival rate of radical gastrectomy is about 40%. The main reason for treatment failure is the high rate of lymph node metastasis along the left gastric artery, hepatic artery, and celiac artery stem, and it is difficult to eradicate the cancerous nest around the blood vessel. That is to say that radical surgery, but the surgical area can still residual cancer. Radiation therapy has little effect on gastric cancer, and external irradiation of the stomach area can cause damage to the small intestine, thus limiting the completion of the full amount of radiation therapy. To increase the cure rate of gastric cancer,
