Quality of life outcomes after low dose-rate brachytherapy for localized prostate cancer: Current status and future perspectives.

The present review summarizes data from studies reporting on health-related quality of life after brachytherapy and competing modalities. There are various therapeutic modalities for localized prostate cancer, including radical surgery, external beam radiotherapy and active surveillance. Advances in surgical and radiation treatment have entered clinical practice in the form of robot-assisted surgery or intensity-modulated radiotherapy. Brachytherapy remains the main treatment option for patients with localized prostate cancer, with 10-year survival data showing favorable outcomes. Because each treatment modality has achieved favorable survival outcomes, focus in determining appropriate treatment has shifted toward health-related quality of life, where each treatment has a different profile and/or adverse symptoms. The development of health-related quality of life assessment tools has allowed the creation of a pool of specific health-related quality of life data across many studies. The present article reviews the impact of brachytherapy and other modalities on quality of life, as well as future directions.
