【摘要】 目的 探讨全肝或部分肝的三维适形半野轮照放射治疗(放疗)技术治疗局部晚期原发性肝癌的临床疗效。方法 40例局部晚期肝癌, 随机给予三维适形半野轮照放疗技术治疗(放疗组)和最佳支持治疗(对照组), 各20例。观察两组中位总生存期(OS)、中位无疾病进展时间(DFS), 并观察放疗组治疗并发症情况。结果 放疗组中位总生存期10.0个月, 中位无疾病进展时间(DFS)7.0个月;对照组中位总生存期7.0个月, 中位无疾病进展时间3.0个月;放疗组中位总生存期、中位无疾病进展时间均优于对照组(P<0.05)。放疗组未见肝功能进行性恶化、黄疸、腹水等放射性肝炎症状发生。结论 根据患者的个体情况采用半野轮照放疗技术作为局部晚期原发性肝癌辅助治疗手段, 可获得较好疗效, 毒副作用可耐受。

【Abstract】 Objective To investigate clinical effect by three-dimensional conformal semi-field irradiation radiotherapy for whole or partial liver in the treatment of locally advanced primary liver cancer. Methods A total of 40 patients with locally advanced liver cancer were randomly given three-dimensional conformal semi-field irradiation radiotherapy (radiotherapy group) and best supportive care for treatment (control group), and each group contains 20 cases. Observation was made on median overall survival (OS), median disease-free survival (DFS) in both groups, and complications in the radiotherapy group. Results The radiotherapy group had median overall survival as 10.0 months and median disease-free survival as 7.0 months. The control group had median overall survival as 7.0 months and median disease-free survival as 3.0 months. The radiotherapy group had all better median overall survival and median disease-free survival than the control group (P<0.05). The radiotherapy group had no complications with radiation hepatitis symptoms, such as liver function ingravescence, jaundice and ascites. Conclusion Implement of semi-field irradiation radiotherapy on the basis of individual situation in patients provides excellent curative effect in treating locally advanced primary liver cancer, along with tolerable toxic and side effects.

原发性肝癌是一种常见又难治的恶性肿瘤。全球新发肝癌病例中, 53%发生在我国, 2000年发病率达54.7/10万[1]。局部晚期肝癌指肿瘤巨大和(或)多发子灶、癌栓、肝门淋巴结转移而不能手术切除, 不仅比例较高, 达到临床首诊的70%~80%, 而且病情重、进展极快, 若不进行有效干预, 大多生存时间很短[2]。目前局部晚期肝癌仅小部分可行肝动脉化疗栓塞术(TACE)、靶向治疗(如索拉非尼), 且疗效不佳。放射治疗在肝癌治疗中已有广泛应用, 但对局部晚期肝癌, 顾忌到肝功能耐受, 局部大野、多野调强、局部高剂量等技术条件开展困难。为此, 作者设计了全肝或部分肝的三维适形半野轮照放疗技术来治疗局部晚期原发性肝癌, 并取得了较好的临床效果, 现报告如下。
