目的比较晚期肾癌免疫化疗和单纯免疫治疗的治疗效果,选择更好的治疗方法。方法IL-2针每公斤体重6~10万单位Q8h静脉滴注,5氟-尿嘧啶1.5 g缓慢静脉滴注,维持时间约12~16h。每周一至周四连用4 d,每月连用2周。结果完全缓解2例占16.6%,部分缓解3例占25%,总有效率41.6%。结论小剂量白介素联合5氟尿嘧啶治疗晚期肾癌总有效率达41%,高于IL-2联合IFN的20%有效率。为晚期肾癌的治疗提供了一种更好的治疗手段。 Objective To compare the therapeutic effects of immunotherapy with chemotherapy for advanced renal cell carcinoma and simple immunotherapy and to choose a better treatment. Methods IL-2 needles were intravenously injected with Q8h at a dosage of 6-100,000 kg / kg body weight and 5-fluorouracil 1.5 g by slow intravenous infusion for 12-16 hours. Use 4 days a week from Monday to Thursday and 2 weeks a month. Results of complete remission in 2 cases accounted for 16.6%, partial remission in 3 cases accounted for 25%, the total effective rate was 41.6%. Conclusions The total effective rate of low-dose interleukin combined with 5-fluorouracil in advanced renal cell carcinoma is 41%, which is higher than that of IL-2 combined with 20% IFN. For the treatment of advanced renal cancer provides a better treatment.
