ABSTRACT
BACKGROUND:
High-dose-rate brachytherapy (HDR-BT) is an accepted part of treatment for endometrial carcinoma and is usually performed in 1-2 fractions per week using different total doses and doses per fraction. To reduce the overall treatment time, HDR-BT was administered with a 3-4 days/week schedule. PATIENTS ANDMETHODS:
From June 2003 to December 2008, 164 patients with stage I-IIIc endometrial carcinoma were treated with HDR-BT (4-5 Gy per fraction). The patients were divided into two groups; Group 1 (40/164 patients) was treated with HDR-BT alone (6 fractions; 4 fractions/week) and Group 2 (124/164 patients) was treated with both (External Beam Radiotherapy [EBRT] + HDR-BT 3 fractions/week). Complications were analyzed using RTOG scores for rectum and bladder and the objective scores of LENT-SOMA for vaginal complications.RESULTS:
The mean followup was 48 months. In Group 1, 35 % of patients underwent treatment in ≤10 days and 65 % in >10 days. In Group 2, 53.2 % received treatment in ≤5 days and in 46.8 % in >5 days. Vaginal relapse was observed in only two patients (1.2 %), both having received adjuvant EBRT + HDR-BT. Acute vaginal toxicity appeared in 8.5 % and late vaginal toxicity in 20.7 % of patients with 13.4 % being G1, 6.7 % G2 and only 0.6 % being G4. No statistically significant differences were found in complications in either brachytherapy group regardless of the overall time.CONCLUSION:
In our series, three fractions given in 3-5/days after EBRT or six fractions in 10 days, is a safe regimen in terms of complications and local control (AU)
