“…Pelvic failure rates following brachytherapy alone range from 14% to 33% [24,27]. Although several studies have shown no difference in outcome from adding external beam radiation therapy (EBRT) to brachytherapy for stage I disease [27,31,32], others have advocated for using that combination in patients with higher grade and infiltrative lesions, given the increased risk of local-regional failure [29,33,34]. In stage II disease, the combination of EBRT and brachytherapy has been associated with improved pelvic control and survival [27].…”
