Postop Hypofractionated Radiation Therapy and LHRH in Patients With Prostate Cancer

Summary

Prostate cancer is the second most common cancer among Canadian men of which approximately 20-30% present with high-risk tumour characteristic. Although surgery can be curative in patients evidencing pathological high-risk disease (extracapsular extension, seminal vesicle involvement, positive surgical margins), a large proportion will develop biochemical failure within years from the surgical procedure. The failure rate is even more pronounced in those patients that present with high prostate specific antigen (PSA) levels, pT3 disease, positive margins and Gleason score ≥8 with an estimated 75% failure rate at 10 years. Post-operative radiotherapy (RT) has been shown in three randomized trials to significantly decrease the biochemical failure rate and in one of the trials a survival benefit was also seen with the addition of post-operative RT and is considered by many investigators standard therapy in patients with pathological high-risks factors even in absence of biochemical failure.
