原发性肝癌尤其是中晚期患者的治疗是非常困难的。1990年6月到9月，我所采用组织间插植和外照射结合治疗了6例中晚期不能手术切除的原发性肝癌患者，国内尚无报道。患者均为男性，年龄33到50岁。6例病人中有1例为弥散型，其余单巨块型。患者在全麻下进行手术。首先在直视下探查肝癌瘤体的部位及大小，根据探查结果将可弯曲的塑料导管插入病灶中心，其数量及排列方式根据瘤体大小而定。利用CT进行施源导管定位，并用TPS进行剂量计算。手术后一周开始采用高剂量率Ir—192micro—Selectron治疗机进行治疗。每周治疗三 The treatment of primary liver cancer, especially in the middle and late stage, is very difficult. From June to September 1990, 6 cases of primary liver cancer patients that could not be resected in the middle and late stage were treated with interplanting and external beam irradiation, which has not been reported in China. The patients were all male and were 33 to 50 years old. One of the 6 patients was diffuse and the rest was monolithic. The patient underwent surgery under general anesthesia. Firstly, the location and size of the hepatocellular carcinoma were explored under direct vision. According to the results of the exploration, a flexible plastic catheter was inserted into the center of the lesion. The number and arrangement of the catheters were determined according to the size of the tumor. Localization of the donor catheter was performed using CT and dose calculations were performed using TPS. One week after surgery, the high-dose rate Ir-192micro-Selectron treatment machine was used for treatment. Weekly treatment three
