从1978年～1985年对71例Ⅲ和Ⅳ_a宫颈癌作了腔内高剂量率照射。年龄37～79岁,平均61.8岁。按FIGO分期Ⅲa 7例,Ⅲb46例,Ⅳa18例。鳞癌68例,腺癌2例(Ⅲb),腺鳞癌1例(Ⅲb)。所有Ⅲ期与18例Ⅳa中的13例用外照射与腔内照射,Ⅳa中5例单给外照射,照射后如肿瘤还大则给腔内照射。外照射用10MV直线加速器,源轴距100cm,前后野,上迄L_5上缘,下至闭孔下缘(当阴道侵犯则按肿瘤范围定),则缘超过盆骨最宽直径2cm,剂量39.6～70Gy(平均47.2Gy),46例外照射时中央屏蔽,剂量10～20Gy(平均17.8Gy)。
From 1978 to 1985, 71 patients with stage Ⅲ and Ⅳ_a cervical cancer were treated with intraluminal high dose irradiation. Age 37 to 79 years old, average 61.8 years old. According to FIGO staging Ⅲ a 7 cases, Ⅲ b 46 cases, Ⅳ a18 cases. 68 cases of squamous cell carcinoma, 2 cases of adenocarcinoma (Ⅲb) and 1 case of adenosquamous carcinoma (Ⅲb). All Ⅲ and 18 cases of IVa in 13 cases with external irradiation and intracavitary irradiation, IVa in 5 cases of single external irradiation, such as the tumor is still larger after irradiation to the cavity irradiation. External beam with 10MV linear accelerator, the source wheelbase 100cm, before and after the field, on the edge until L_5, down to the lower edge of the obturator (when the vaginal invasion by tumor range), the edge exceeding the pelvis widest diameter of 2cm, a dose of 39.6 ~ 70Gy (average 47.2Gy), 46 were centrally screened at a dose of 10 ~ 20Gy (average 17.8Gy).
