We aimed to analyze the treatment results and the acute and late side effects in patients with stage I endometrial carcinoma receiving adjuvant radiotherapy.

METHODS
Two hundred sixty-three patients with stage I endometrial adenocarcinoma, who were treated with postoperative radiotherapy between 1978 and 1998, were analyzed retrospectively. According to the 1988-FIGO staging system, the disease was stage IA in 19, stage IB in 128, and stage IC in 116 patients. One hundred and ninety-seven patients were treated with external and intracavitary irradiation, 45 patients with external radiotherapy and 21 patients with vaginal brachytherapy.

RESULTS
The 10-year local control, disease-free and actuarial survival rates were 96%, 93% and 95%, respectively. Fifty-five patients had late side effects. The late side effects were significantly higher in patients with acute toxicity and patients who were treated with external radiotherapy, followed by brachytherapy.

CONCLUSION
The decision of adjuvant therapy and choice of different treatment modalities in terms of a reduced risk of recurrence need to be weighed carefully against the treatment-related morbidity. Keywords : Endometrial cancer; stage I; postoperative radiotherapy; long-term results
