 Hypothesis: The clinical outcome of radical radiation therapy including Conventional radiography based brachytherapy for International Federation of Gynecology and Obstetrics FIGO Stage IIB and IIIB reported in historical series is 75 and 55 local control rates and grade 34 rectal bladder toxicities of 10-15. With the addition of concomitant cisplatin chemotherapy there is an additional local control benefit of 5-10 and potentially increase in late toxicities no substantial evidence for toxicities reported so far. With the MR Image Based Brachytherapy approach, mono-institutional series and phase II multicentric international study, the results reported so far show an improvement in local control rates to 96 and 86 for IIB and IIIB respectively and late toxicities 5 reported so far. We propose this randomized control study to test the following hypothesis: With the use of MR Image Based Brachytherapy Study Arm in locally advanced cervical cancers Stratified for Stage IIB and IIIB, there will be an absolute increase in local control rates by 10 and reduction in late rectal and bladder toxicities by 5 - 10 as compared to the Conventional radiography based ICBT. Thus, for demonstrating absolute local control benefit of 10 in Stages IIB 85 to 95 and Stage IIIB 65 to 75 a total of 1050 patients 350 patients with Stage IIB and 650 patients with stage IIB respectively will be accrued.
