Summary:
Objective: The aim of our study was to fi nd the infl uence of the postoperative radiotherapy on local
control and overal survival in patients with carcinoma of the uterus. Endometrial carcinoma
is the most frequent gynecologic malignity. Surgery, radiotherapy, chemotherapy and hormonal
therapy are used in the treatment of this disease. The optimal cure strategy has not been established
yet.
Design: retrospective study.
Setting: Department of Radiation Oncology, Masaryk Memorial Cancer Institute, Brno.
Methods: We followed up 246 patients with the diagnosis of endometrial carcinoma. All patients
were in clinical stage 1. Median of the age was 60 years. Every patient underwent radical hysterectomy
and adnexectomy. Most of them had adjuvant radiotherapy. Combined radiotherapy
was used (external beam radiotherapy and brachyradiotherapy). Some of patients underwent
only external beam radiotherapy, other had only brachytherapy. We used Kaplan-Meier survival
function and methods of Statistica.
Results: The median of the follow up was 8.3 years. Local recurrence was proved in 16 cases. The
time to the local relapse was 3.2 years. Dissemination occurred in 12 patients. The time to the
progression was 5.9 years. Five-year DFS was 80.9%, fi ve-year overal survival was 82.9%. Patients,
who had risk factors, were proved to suffer from worse overal survival. The adjuvant radiotherapy
improved the local, and the distant control in the group of patients with risk factors.
Conclusion: The infl uence of the radiotherapy on the local control was proved in many studies,
the infl uence on the overal survival was not statistically signifi cant. Temporally there is the option
not to apply adjuvant radiotherapy. Our study shows the important benefi t of the adjuvant
treatment in cases of endometrial carcinoma and risk factors.
