作者从1983～1989年,对284例宫颈癌作了高剂量率腔内近距离治疗(HDR—ICR),其中31例在别处作外照射而除外,余下253例作为分析的对象。年龄24～88岁(平均65岁),按FIGO分期,0期6例,Ⅰ_A 4例,Ⅰ_B 14例,Ⅱ_A 4例,Ⅱ_B 68例,Ⅲ_A 3例,Ⅲ_B 128例,Ⅳ_A 14例,Ⅳ_B 13例。鳞癌243例(96％),腺癌7例(3％),腺鳞癌3例(1％)。随访至少4年或至死亡。 放疗法:0及I_A者单纯作ICR,余作ICR与外照射联合。外照射用10MV直线加速器,前后对穿野,上缘在L_(4～5)间,下缘到闭孔中份,侧缘超出骨盆最宽点至少1cm,每日中线平面剂量1.8～2Gy,平均总
From 1983 to 1989, 284 cases of cervical cancer were treated with high-dose endovascular brachytherapy (HDR-ICR). Of the 31 cases, 31 were treated with external exposure elsewhere, with the remaining 253 as subjects for analysis. Aged 24 to 88 years old (average 65 years), according to FIGO staging, stage 0 in 6 cases, Ⅰ_A 4 cases, Ⅰ_B 14 cases, Ⅱ_A 4 cases, Ⅱ_B 68 cases, Ⅲ_A 3 cases, Ⅲ_B 128 cases, Ⅳ_A 14 cases, Ⅳ_B 13 example. 243 cases of squamous cell carcinoma (96%), 7 cases of adenocarcinoma (3%) and 3 cases of adenosquamous carcinoma (1%). Follow up for at least 4 years or until death. Radiotherapy: 0 and I_A were simply for ICR, remaining for ICR combined with external irradiation. Outer irradiation with 10MV linear accelerator, before and after the pair of field, the upper edge of the L_ (4 ~ 5), the lower edge to the obturator in the lateral edge of the pelvis beyond the widest point at least 1cm, daily median dose of 1.8 ~ 2Gy, Average total
