Image-guided brachytherapy for gynecologic surgeons.
Brachytherapy is a fundamental component of the definitive treatment of many advanced gynecologic malignancies, most notably cancers of the uterine corpus and cervix, and allows high radiation doses to be delivered to the target while minimizing the normal tissue dose. However, dose specification has been based primarily on points visible on plain radiographs, with limited correlation to a patient's anatomy and extent of disease. Recent advances have allowed more customized volume-based specification of dose, which has allowed improvements in outcomes. This article reviews these advances using cervical cancer as a model, and looks to future directions with this promising treatment.
