Early stage endometrial carcinoma is usually treated by surgery and radiotherapy if there is a substantial risk of recurrence. The aim of this study was to evaluate early and late toxicity, to determine the sites of recurrence and the prognostic factors which were statistically correlated with survival in patients who were treated with surgery plus external beam radiotherapy. MATERIALS AND METHODS. We have carried out a retrospective analysis of the records of 87 patients treated with hysterectomy plus external beam pelvic radiotherapy (50 Gy/28 Fractions), at the Radiotherapy Division of the CRO Aviano PN Italy, between 1985 and 1990. The median length of follow-up was 32.42 months. RESULTS. The treatment was well tolerated. The median time to recurrence was 6.56 months. There were 4.7% local, 5.8% distant and 3.5% local plus distant recurrences. As of May 1993 83.2% of the patients were still alive. All deaths occurred within two years from the beginning of treatment. The prognostic factors which were significantly correlated with survival were the stage of the disease (p = 0.0479), depth of myometrial invasion (p = 0.0429), age greater than 64 years (p = 0.0357) and performance status < = 80 at diagnosis (p = 0.0002). CONCLUSIONS. Our study confirms that post operative external beam pelvic RT is well tolerated and effective in achieving a good locoregional control. All the factors investigated were prognostic for survival, except histological grade, lymph node involvement and RT dose.
