To evaluate the overall and disease-free survival of patients with advanced cervical carcinoma (FIGO stages IIB-IIIB) treated with external beam radiotherapy (EBRT) and medium dose rate brachytherapy (MDR-BT) plus/minus surgery.One hundred and seven patients received preoperative RT (group A) and 154 were treated with definitive RT (group B); 73 patients in both groups also received cisplatin as radiosensitizer. EBRT delivered as preoperative reached a total dose of 44-46 Gy/pelvis, whereas the definitive RT reached a total dose of 62-64 Gy with standard fractionation. MDR-BT was performed with a LDR/MDR Cs-137 Selectron machine; 10 Gy/point A were delivered in the preoperative group A and 14 Gy/point A/, 1-2 fractions in group B. Cisplatin as radiosensitizer was administered during EBRT at a dose of 20 mg/m(2)/day for 5 days with 21 days interval between cycles.With a median follow-up of 44.4 months (range 3.4-61.6) the overall survival at 3 years in group A was 92% vs. 68% for group B (p0.01). According to FIGO stages 3-year overall survival was 88% in stage IIB, 79% in IIIA and 60% in IIIB (p0.01). Three-year local control was 73.5% (192 patients). Thirty-three (13%) patients developed locoregional recurrences, and another 8 (3.07%) locoregional recurrences plus distant metastases.The association of EBRT with MDR-BT represents an effective treatment in advanced cervical carcinoma. A significant difference in 3-year overall survival was found, favoring preoperative RT, with a very good rate of local control. |
