ABSTRACT
Purpose: We are reporting results of a randomized study with the aim to compare the results of low-dose rate (LDR) versus high-dose rate (HDR) brachytherapy in locally advanced carcinoma cervix patients. Material and methods: Sixty cases of carcinoma of uterine cervix in Stage IIB-IIIB (FIGO) were included from a period of January 2002 to March 2003 and were randomized into HDR brachytherapy (6 Gy/fraction for 4 sessions) or LDR brachytherapy (27 Gy/single session) arm after completion of external beam radiotherapy (50 Gy/25#/5 weeks). Results: In HDR arm, 16/30 (53.33%) patients experienced complete response. In LDR arm, complete response was experienced by 13/30 (43.33%) of patients. Locoregional control in HDR group was 54.54%, 57.14% and 71.42% at 6, 9 and 12 months, respectively. Locoregional control in LDR group at 6, 9 and 12 months was 45%, 63.63% and 42.85%, respectively. Conclusion: The results of our study indicate that LDR and HDR groups are similar in locoregional control in the management of carcinoma uterine cervix. HDR brachytherapy can safely substitute LDR brachytherapy applications.
