This paper presents the source, applicators and treatment results of the first 192Ir afterloading machine manufactured at home. The intrauterine source can effect pendulous displacements in linear or non-linear patterns without preparatory dilatation. The vagina source can assume palisade and erect position. Satisfactory dose distributions are possible by various arrangements of the vaginal applicators as required clinically. From Oct. 1984 to Dec. 1985, 82 patients with cervical malignancies were treated by this machine. The tumor mass in all patients disappeared before the conclusion of treatment. There was no local recurrence with the longest follow-up of one year as compared to the tumor inhibition rate of 91.9% by the traditional method during the same period. These results suggest that this facility be satisfactory and that the traditional intracavitary treatment could be replaced.
本文介绍了国产首台192铱后装治疗机的源、施源器及治疗效果。宫腔源无需预先扩张即可呈线性或非线性方式产生下垂移位。阴道源可呈栅栏状和直立位。根据临床需要对阴道施源器进行各种排列可获得满意的剂量分布。1984年10月至1985年12月，用该机治疗了82例宫颈癌患者。所有患者的肿瘤块在治疗结束前均消失。最长随访1年无局部复发，同期传统方法的肿瘤抑制率为91.9%。这些结果表明该设备令人满意，可取代传统的腔内治疗。
