Two-fraction HDR Monotherapy for Localized Prostate Cancer

Status Not yet recruiting

Clinical Trial Summary

This is a single center single arm prospective pilot study investigating the safety of high dose rate (HDR) brachytherapy as monotherapy delivered in 2 fractions 3 hours apart. HDR monotherapy has been established as safe and effective in this context, however previous studies have delivered 2 fractions on separate days, or at least 6 hours apart. Clinically, this regimen, if shown to be safe and effective in future studies, has the potential to reduce operative resources and logistical stresses on brachytherapy departments.

Clinical Trial Description

PRIMARY OBJECTIVES: I. To determine the safety of HDR monotherapy 13.5 Gy x 2 fractions delivered 3 hours apart in patients with low and intermediate risk prostate cancer. SECONDARY OBJECTIVES: I. To describe the prostate specific antigen (PSA) kinetics associated with HDR brachytherapy monotherapy 13.5 Gy x 2 fractions delivered 3 hours apart for low and intermediate risk prostate cancer. OUTLINE: Treatment will be administered on an outpatient basis. All treatment will be delivered over a single day. Participants will be followed for 6 months after last treatment or removal from study, or until death, whichever occurs first. Additional Follow up will be as per usual guidelines for prostate cancer, every 3 months following treatment with PSA for the first year, then every 4 months after year 2, and every 6 months after year 3 until 5 years of follow up are completed. ;
