Objective: To analyze retrospectively results of cervix carcinoma treated by high dose rate 192Ir intracavitary brachytherapy and external irradiation. Methods: From May 1993 to May 1997,54 cases of cervix carcinoma were treated by combined external radiation with brachytherapy . The patient population consisted of 2 cases with stageⅠ disease
29 cases with stage Ⅱ disease
21 cases with Stage Ⅲ disease and 2 cases with stage Ⅳ disease . The total dose of the external and intracavitary irradiation at point A and B was 65~85Gy and 50~70Gy ,respectively. The total treatment time was 6~8 weeks . Results: The survival rate of 1、3、4 year after radiotherapy was 81.5%,68.5% and 61.1% ,respectively. The 4-year survival for stages Ⅰ、Ⅱ、Ⅲ and Ⅳdisease were 100%、75.8%、42.8% and 0%
respectively .The clinical stage of disease is an important prognostic factor . The incidence of complication was 31.5% for radiation proctitis and 11.1% for cystitis. Conclusion:HDR brachytherapy with external irradiation for the cervix carcinoma is an effective method. To improve tumor control and reduce complication rate more research is necessary.
