肝动脉内持续灌注治疗结直肠癌术后肝转移瘤

目的：探讨5－氟尿嘧啶（5－Fu)／甲酰四氢叶酸钙（CF）经肝动脉持续性灌注治疗结直肠癌肝转移的临床疗效。方法：62例无外科手术指征的结直肠癌肝转移患者，其原发病灶均已作根除术，依据肝动脉内化疗方式不同分为2组：A组32例，采取经皮肝动脉内植入药盒，术后经药盒每个月连续5d持续灌注5－Fu／CF及地塞米松；B组30例，采取每个月1次肝动脉插管大剂量灌注5－Fu/CF。结果：A，B组有效率（完全缓解＋部分缓解）分别为50．0％和23．3％（P＜0．05）。A组1年，2年生率分别为65．6%，39．3％，B组分别为36．7％，11．5％（P＜0．05）。A组1年，2年生存率分别为65．6％，39．3％，B组分别为36．7％，11．5％（P＜0．05）。A组生存质量明显改善，肝，胆，胃十二指肠毒性均较B组低。结论：经药盒肝动脉持续性灌注5－Fu/CF并配合地塞米松治疗结直肠癌肝转移可明显改善患者生存质量，提高生存率。

Continuous hepatic arterial infusion therapy for nonresectable liver metastases from colorectal carcinoma

Objective To evaluate the efficacy of continous hepatic arterial infusion chemotherapy to nonresectable liver metastases from colorectal carcinoma. Methods Sixty-two patients with nonresectable liver metastases from colorectal carcinoma had been treated with radical operation, and the patients were divided into 2 groups. (1) Group A: 32 patients received continuous hepatic arterial infusion of 5-Fluorouracil (5-Fu)/Calcium Folinate (CF) and dexamethasone via drug delivery system (DDS) implanted percutaneously for 5 days every month. (2) Group B: 30 patients were treated through one bolus arterial infusion of 5-Fu/CF each month. Results The response rate (CR+PR) of group A and B was 50.0% and 23.3%,respectively (P<0.05); the survival rate for 1 and 2 years in group A was 65.6% and 39.3%,respectively, but that in group B was 36.7% and 11.5%, respectively (P<0.05); the toxic reaction at liver, biliary, and gastrointestinal tract in group A was significantly lower than that in group B. Conclusion Continuous hepatic arterial infusion of 5-Fu/CF and dexamethasone via DDS can prolong the survival rate and improve quality of life in patients with nonresectable liver metastases from colorectal carcinoma.
