Abstract
To investigate the radiotherapy modality progress of stageIIb-IIIb cervical stump cancer. The clinical data of 13 patients with stageIIb-IIIb cervical stump cancer undergoing radiotherapy from January 2000 to April 2012 was reviewed. Before 2006, 8 patients received conventional external beam radiotherapy and brachytherapy.Since 2006, 5 patients received intensity-modulated radiotherapy (IMRT) and brachytherapy. The median survival was 12-139 months. The median overall survivals and disease free survivals in the conventional radiotherapy (CRT) group were 57 months and 50 months, 3 cases of them recurred during 8-19 months and died of tumor progression.While, the median overall survivals and disease free survival in the IMRT group both were 21 months and nobody recurred. In the CRT group, 7 patients suffered toxicities, including 5 patients grade I-II acute rectum reaction, 2 patients grade I bladder reaction; and 3 had grade I-III, late rectum reaction, 2 patients for grade II bladder late reaction.In the IMRT group, toxicities including 1 case grade I acute or late rectum reaction, and no bladder reaction. In our experience, the recommended IMRT and interstitial brachytherapy for the selected patients with advanced cervical stump carcinoma may be obtain better tumor dose distribution and more sparing of the organ at risk.
