摘要
目的:探讨X射线三维适形放射治疗中晚期肝癌的近期疗效和副反应。方法:56例肝脏恶性肿瘤(62个病灶),其中43例为原发性肝癌,13例为转移性肝癌,采用三维适形放疗技术(3DCRT)治疗,设射野5～7个,治疗次数5～10次,每次间隔1～2天,每次治疗周边剂量4～8 Gy,总剂量DT:30～45 Gy。结果:治疗后1～3个月内根据CT或MRI复查肿瘤退缩情况确定15病灶CR(24%),31个PR(50%),10个NC(16%),6个PD(10%),总有效率(CR+PR)达74%。结论:三维适形放射治疗肝脏恶性肿瘤是一种安全有效的方法,副反应小,能为大多数患者所耐受,有较好的近期疗效,小病灶疗效更好;远期疗效和后期放射损伤有待进一步观察。
Purpose:To evaluate the curative effects and side effects of 3-dimensional conformal radiotherapy (3DCRT) in the treatment of liver carcinoma.Methods:56 patients with liver carcinoma (Forty three patients were primary hepatic carcinoma and 13 liver metastatic tumors) with 62 lesions were treated with 3DCRT for 30～45 Gy/5～10 f/1～2 weeks with fractionated doses ranging from 4Gy to 8Gy.Results:In the 1～3 months after 3DCRT the results examined by CT or MRI showed that the 62 lesions(56 patients) had CR 24% (15/62),PR 50%(31/62),NC 16% (10/62) and PD 10% (6/62).The overall response rate (CR+PR) was 74%.Conclusions:3DCRT is an effective and safe treatment for hepatic malignant tumor and it can be tolerated by most of the patients.The immediate response of tumor is encouraging. The survival rate and late complications remain to be observed.
