Abstract:
Purpose:To evaluate two different methods of radiotherapy, which affect the results of cervical cancers treated and complications of the rectum or bladder. Methods:From July 1991 to December 1996, 124 cases of cervical cancer were randomly allocated into two groups. Group A (59 cases:stage Ⅰ 1, Ⅱa 12, Ⅱb 30, Ⅲa 11, Ⅲb 5) received 45—55 Gy of external radiation(ER) to the parametrium and 50—65 Gy of intracavitary irradiation (4—5 Gy per fraction, 2 fractions per week). Group B(65 cases: stage Ⅰ 2, Ⅱa 15, Ⅱb 29, Ⅲa 10, Ⅲb 9) received 26—40 Gy ER to the whole pelvic and 30—40 Gy of intracavitary irradiation (4—5 Gy per fraction, 2 fractions per week), an additional 15—29 Gy ER to the parametrium. Results:In group A, 3 year and 5 year survival rates were 81.4% and 71.7%. In group B, they were 84.6% and 70.8%. The rates of complication for the rectum were 25.4%(3 year) and 21.7%(5 year) in group A, 10.8%(3 year) and 8.3%(5 year) in group B. The rates of rectal complication( P
