因只有50％左右的胃癌可以手术切除而治愈,而不论单纯术前化疗还是单纯术后辅助化疗对大多数胃癌患者来说均不能提高其生存率,所以作者将术前化疗与术后腹腔内化疗联合应用。其目的在于术前缩小原发肿瘤的大小及范围,消除远处的微小病灶,从而提高切除率。 Because only about 50% of gastric cancers can be cured by surgery, neither preoperative chemotherapy nor postoperative adjuvant chemotherapy can increase the survival rate of most patients with gastric cancer. Therefore, the authors combine preoperative chemotherapy with postoperative intraperitoneal injection. Chemotherapy combined application. The purpose is to reduce the size and extent of the primary tumor before surgery, eliminate distant microscopic lesions, and increase the resection rate.
