Results of radiotherapy alone in the treatment of carcinoma of uterine cervix: a retrospective analysis of 1069 patients

Abstract

Carcinoma of the uterine cervix is the most common malignancy affecting women in developing countries like India. This retrospective study was made to analyze our results of radiotherapy alone in the treatment of carcinoma cervix. Between January 1996 and December 2001, 1069 patients of carcinoma cervix were treated at our center with external beam radiotherapy (EBRT) and intracavitary radiotherapy (871) or EBRT alone (198). The median dose to point A was 81 Gy. Overall survival (OS), disease-free survival (DFS), and pelvic control at 5 years were 51.8%, 49.4%, and 63.9%, respectively. For the patients who could receive intracavitary radiotherapy (871), the OS, DFS, and pelvic control rates were 60.7%, 58.6%, and 73.5%, respectively. On multivariate analysis, bulk, overall treatment time (OTT) and response to EBRT were found to affect OS and DFS independently. Similarly, OTT, response to EBRT, stage, and age were the factors that influenced pelvic control. Incidence of severe late toxicities (grade 3/4) in the rectum, bladder, small intestine, and skin were 1.1%, 1.2%, 0.2%, and 1.2%, respectively. In developing countries like India, where chemoradiation can be afforded by a minority only, judicious use of radiotherapy still produces satisfactory results with acceptable toxicity. The addition of chemotherapy may be beneficial in patients with adverse prognostic factors.
