    Abstract:
    OBJECTIVE: The aim of present study was to analyze the results of pulsed-dose-rate (PDR) brachytherapy in patients with cervical carcinoma treated at our center. METHODS: From September 2003 to September 2005, 48 patients with histopathologically proved cervical carcinoma, stages IB to IVA, were treated with PDR intracavitary radiotherapy (ICRT) and pelvic irradiation at our center. Radiotherapy consisted of whole pelvis external beam radiation therapy (EBRT) with a dose of 40 Gy in 22 fractions over 4.5 weeks followed by 10 Gy in 5 fractions over 1 week with midline shielding. Weekly chemotherapy (Cisplatin, 40 mg/m) was administered during the course of EBRT to suitable patients. After an interval of 1 to 2 weeks, a single session of standard ICRT application was done to deliver a dose of 27 Gy to point A by PDR (hourly pulse, 70 cGy). RESULTS: Median age was 50 years (range: 30-65). FIGO stage distribution of the patients was as follows: stage IB, 6; stage IIA, 1; stage IIB, 15; stage IIIB, 25; and stage IVA, 1. Follow-up period ranged from 3 to 50 months (median: 15 months). Ten patients had disease recurrence (5 each in stage IIB and stage IIIB). Eight patients had pelvic failure, 1 had bone metastases, and 1 had supraclavicular node metastases. Overall grades III to IV late toxicity rate at 50 months was 6%. For the median follow-up period of 15 months, the actuarial recurrence-free survival in stages I to II was 82% and stages III to IV was 78%. CONCLUSION: Our results reveal that PDR ICRT in combination with pelvic EBRT provides excellent pelvic disease control, survival, and low radiation related morbidity rate in the patients with cervical carcinoma.
