HDR Focal: Feasibility Study

Official Title

HDR Monotherapy for Prostate Cancer: A Feasibility Study of Focal Radiation Therapy Yields

Summary:

Brachytherapy as a monotherapy treatment is highly effective for localized prostate cancer, traditionally being delivered to the whole prostate gland. Lately, low dose rate (LDR) brachytherapy has been increasingly replaced by high dose rate (HDR) brachytherapy treatment schemes. While brachytherapy's oncologic outcomes are excellent, it is not without incidence adverse effects including urinary, rectal, and sexual toxicities that affect the patient's quality of life.

This study will incorporate HDR monotherapy treatment option for early stages and favourable risk prostate cancer.

Additionally, we aim to evaluate the role of focal HDR brachytherapy for well-defined disease based on multiparametric MRI (mpMRI). This approach may offer an option of reducing the treatment toxicities while maintaining oncologic outcomes when compared with whole-gland therapy. Advantages in quality of life could be exhibited in the form of reduced urinary discomfort and incontinence, rectal symptoms, and improved erectile and prostatic gland function. This study would be particularly relevant in the current era of earlier localized prostate cancer detection, where newer imaging modalities (e.g. mpMRI) become a routine component of patient care.
