胃癌的化学疗法是胃癌综合治疗的措施之一,有益于提高5年生存率,也是对晚期癌和复发癌的辅助治疗手段,目的在于改善生存质量,延长生存期。一、以手术为主的辅助化疗早期胃癌根治术后,原则上不必辅助化疗。但对病灶面积较大,病理类型恶性度高的应酌情化疗。进展期胃癌无论有无淋巴结转移,术后均需化疗,非根治手术的病人,如姑息切除、改道、开腹探查等,术前、术中、术后均应考虑化疗。 1.术前化疗:根据胃纤维内窥镜、X线、CT,有条件者行超声纤维内窥镜检查估计不能行根治切除者,可做术前化疗,手术前1周给5-FU500mg,静滴,
Gastric cancer chemotherapy is one of the measures for comprehensive treatment of gastric cancer, which is beneficial to increase the 5-year survival rate. It is also an adjunct treatment method for advanced cancer and recurrent cancer. The purpose is to improve the quality of life and prolong the survival period. First, surgery-based adjuvant chemotherapy After radical gastrectomy, in principle, there is no need for adjuvant chemotherapy. However, for the larger area of the lesion, the pathological type of high degree of malignancy should be treated as appropriate. Progressive gastric cancer requires chemotherapy both with and without lymph node metastasis. For patients undergoing non-radical surgery, such as palliative resection, diversion, and laparotomy, chemotherapy should be considered before, during, and after surgery. 1. Preoperative chemotherapy: According to the gastric fiber endoscope, X-ray, CT, conditional ultrasound fiber endoscopy is not estimated to be radical resection, preoperative chemotherapy can be done, 1 week before surgery to 5-FU 500mg, Instillation,
