Men suitable for prostate brachytherapy as monotherapy will undergo multiparametric Magnetic Resonance Imaging for staging and identification of a dominant lesion and will be randomly selected for either a single low dose rate permanent seed implant or 2 fractions of high dose rate brachytherapy. Using image registration techniques, dominant lesions will be biopsied under anesthesia at the start of the brachytherapy procedure. Biopsies will reviewed for tumor Gleason score and sent for Cell Cycle Progression testing (Prolaris). Patients receiving high dose rate brachytherapy will also have biopsies between the 2 fractions to assess tumor changes induced from the first fraction. Post implant quality assurance will determine the dose to the dominant lesions and compare these between the 2 types of brachytherapy. Post implant symptoms will be tracked for severity and time course.
