Results of radiotherapy alone in 581 patients with Stage II carcinoma of the uterine cervix.

ABSTRACT

From January 1976 to December 1978, 581 previously untreated patients with Stage II carcinoma of the uterine cervix were treated by radiotherapy alone in nine departments of radiotherapy in France. This retrospective analysis was undertaken in an attempt to evaluate the therapeutic results and prognostically significant factors. The initial clinical staging and the therapeutic guidelines were as outlined at the U.T. M. D. Anderson Hospital in Houston; all our patients were treated by standardized protocols combining external beam irradiation and intracavitary irradiation with cesium sources. The overall locoregional control rate was 83.2%, with total disease control of 74.5%. Uncorrected actuarial survival rates are 76% at 3 years and 68% at 5 years. The incidence of severe posttherapeutic complications is 7.2%. Clinical substaging, patient's age at the time of the diagnosis, lymphangiogram findings, and tolerance to external irradiation were all found to have prognostic significance. According to those findings, the possibilities of improving the results are discussed.
