A retrospective analysis was made from 490 patients with carcinoma of uterine cervix who were treated with medial-dose-rate remote afterloading intracavitary irradiation by 137Cs sources in our hospital from 1986 to 1987. At the same time, the results were compared with those of the low-dose-rate intracavitary irradiation therapy. There were 10 cases with stage Ib, 366 with stage IIb and 114 with stage IIIb. The Absolute 5-year survival rate of stage Ib, IIb and IIIb was 90%, 66.1% and 56.1%, respectively. It was clearly demonstrated that the optimal dose should be 55Gy. A fraction of 6-7Gy dose was used once per week. The article suggests that the clinical results by medial-dose-rate afterloading intracavitary irradiation therapy for cancer of uterine cervix are similar to those by the low-dose-rate technique.
对我院1986年至1987年期间采用铯-137源进行中剂量率后装腔内照射治疗的490例子宫颈癌患者进行回顾性分析。同时，将结果与低剂量率腔内照射治疗的结果进行比较。其中Ib期10例，IIb期366例，IIIb期114例。Ib期、IIb期和IIIb期的绝对5年生存率分别为90%、66.1%和56.1%。结果清楚地表明，最佳剂量应为55Gy。每周一次给予6 - 7Gy的分次剂量。文章表明，中剂量率后装腔内照射治疗子宫颈癌的临床结果与低剂量率技术相似。
