Results of radical radiotherapy in carcinoma of the uterine cervix stage I-III.

A retrospective analysis is described of 271 diagnosed cases of carcinoma of the uterine cervix who were treated with radical radiotherapy between January 1987 and July 1988 at the Institute Rotary Cancer Hospital. The mean age at presentation was 49 years and 89% of the tumours were FIGO Stage II and III. The median duration of follow-up was 60 months. The early cases were treated with two intracavitary insertions of 34 Gy each to point A with a Selectron LDR intracavitary system, followed by 36 Gy external radiotherapy to the parametrium. Late stage disease was treated with 50 Gy of external radiotherapy, followed by a single intracavitary insertion of 30 Gy to point A. To compensate for the higher dose rate of the Selectron (180 cGy/h) a dose reduction factor of 15% was applied over the intracavitary dose. There were 2.5% and 4.7% of late Grade III bladder and bowel complications, respectively, requiring surgical intervention. There was no relationship between haemoglobin level at diagnosis and the development of late complications. The actuarial 5-year survivals were 65%, 63% and 35% for Stages I, II and III disease, respectively. This study from the Indian subcontinent shows the effectiveness of radiotherapy in Stages I, II and III carcinoma of the uterine cervix, with acceptable morbidity rates.
