Tumor dose-volume response in image-guided adaptive brachytherapy for cervical cancer: A meta-regression analysis

摘要

PURPOSE: Image-guided adaptive brachytherapy is a high precision technique that allows dose escalation and adaptation to tumor response. Two monocentric studies reported continuous dose-volume response relationships, however, burdened by large confidence intervals. The aim was to refine these estimations by performing a meta-regression analysis based on published series.
