目的分析高剂量率后装治疗原发性阴道癌的疗效。材料与方法1984年1月~1994年4月，共收治原发性阴道癌40例，全部采用外照射加腔内放疗，外照射采用60CO－γ线或直线加速器8MV－X线，腔内照射采用Buchler后装机的中间振荡源。结果所有病例均随访3年以上，40例病人Ⅱ、Ⅲ、Ⅳ期的3年生存率分别为71．4％、55．6％、0．0％，5年生存率分别为57．6％、46．6％、0．0％。轻度放射性直肠炎8例，轻度放射性膀胱炎6例，重度直肠炎1例。结论高剂量率后装安全方便，疗效可靠，适应于更多病例，注意保护，可维持患者正常功能。
Objective To analyze the therapeutic effect of high dose rate afterloading on primary vaginal cancer. Materials and Methods From January 1984 to April 1994, a total of 40 cases of primary vaginal cancer were treated with external irradiation combined with intracavitary radiotherapy, external irradiation using 60CO-γ line or linear accelerator 8MV-X line, intraluminal irradiation Middle oscillator source with Buchler rear mount. Results All patients were followed up for more than 3 years. The 3-year survival rates of stage Ⅱ, Ⅲ and Ⅳ in 40 patients were 71.4%, 55.6% and 00%, respectively. The 5-year survival rates were 57.6% , 46.6%, 0.0%. Mild radiation proctitis in 8 cases, 6 cases of mild radiation cystitis, severe proctitis in 1 case. Conclusion High-dose rate after-loading safe and convenient, reliable, adapted to more cases, pay attention to protection, to maintain normal function in patients.
