奥沙利铂为主的联合化疗结合同期放射治疗晚期直肠癌

Oxaliplation and flurouracil in combination with concurrent radiotherapy for advanced rectal cancer

目的:评价奥沙利铂联合氟尿嘧啶、亚叶酸钙结合同期放疗的疗效。方法:奥沙利铂(L-OHP)130mg/m^2静脉滴注2小时,第1天;氟尿嘧啶(5-FU)300mg/m^2静脉滴注,第1～5天,亚叶酸钙(CF)200 mg/m^2静脉滴注,第1～5天,21天为1周期,治疗3周期。放疗与化疗同期进行,体外照射全盆腔DT 50～60 GY/25～30次(5～6周)。结果:共治疗30例,近期疗效完全缓解(CR)1例;部分缓解(PR)15例;总有效率53.3%。一年生存率为70%(21/30)。主要毒副反应是消化道反应、神经毒性、放射性直肠炎,骨髓抑制轻微。结论:奥沙利铂为主的联合化疗结合同期放疗是治疗晚期直肠癌的有效方法。

Purpose:To evaluate the effect of oxaliplation (L-OHP)+flurouracil/calcium folinate(5-FU/CF) in combination with concurrent radiotherapy for advanced rectal cancer and to find a more effective way of giving them.Meth- ods:Chemotherapy:L-OHP 130 mg/m^2,iv infusion for 2 hours D_1 combined with calcium folinate 200 mg/m^2 for 2 h ours followed by 5-fluorouracil 300 mg/m^2 for 4h D_1～D_5,repeated every 3 weeks.Radiotherapy:The whole pelvic irradiation DT 50～60Gy/25～30/F(5～6 weeks).Results:30 advanced rectal cancer patients entered the study.One patient reached complete response(CR),15 partial response,13 stable disease,and 1 with progression after treatment,The overall re- sponse rate(CR+PR) was 53.3%,the 1-year survival rate was 70% (21/30).The main adverse acute effects were gas- trointestinitis,anemia,neuro-sensory toxicity and irradiation rectitis,bone marrow suppression was mild.Conclusions: This approach of therapy could improve the therapeutic effect on advanced rectal cancer.
