原发性肝癌(HCC)恶性程度极高,确诊时多已为中晚期,一期手术切除率低于10％,部分病例经姑息治疗后可得二期切除。肝癌的姑息治疗种类繁多,如肝动脉栓塞、化疗,局部高温、冷冻、电离、微波、无水酒精注射等,但疗效仍不能令人满意。放射性微球(RMS)区域灌注内放射治疗恶性肿瘤,已经在动物实验和临床中取得了良好的近期疗效,但临床应用尚未广泛开展。 The degree of malignancy of primary liver cancer (HCC) is extremely high. At the time of diagnosis, it is mostly in the middle and late stages. The first-stage surgical resection rate is lower than 10%. In some cases, palliative treatment can result in secondary resection. There are many types of palliative care for liver cancer, such as hepatic artery embolization, chemotherapy, local hyperthermia, freezing, ionization, microwave, and alcohol injection, but the efficacy is still not satisfactory. Radioactive microsphere (RMS) region infusion of internal radiation therapy for malignant tumors has achieved good short-term efficacy in animal experiments and clinics, but clinical applications have not yet been widely implemented.
