Brief Summary:
The purpose of this study is to compare urinary and bowel side effects of hypofractionated radiotherapy in 20 treatments (4 weeks) to ultra-hypofractionated radiotherapy in 5 treatments (2 weeks) for prostate cancer that has returned after prostatectomy. The investigators are also interested in looking at time to progression and the quality of life (health scores).
Detailed Description:
The standard treatment for most patients with biochemical recurrence after radical prostatectomy is salvage radiotherapy. Salvage radiotherapy delays the need for chronic, non-curative treatment, such as long-term androgen suppression, and is the only potentially curative treatment of some biochemical recurrences after prostatectomy.
Patients are recommended to undergo salvage radiotherapy to eradicate biochemical disease delivered in approximately 40 treatments over the course of 8 weeks, representing a high burden of therapy, which may be related to lower utilization of salvage radiotherapy. Modern radiotherapy for prostate cancer has been afforded many advantages including advanced image-guided radiotherapy allowing for larger dose delivery in fewer treatments and smaller margins with hypofractionated (20 treatments) and ultra-hypofractionated (5 treatments) radiotherapy.
In patients that need salvage radiotherapy, the potential advantages of hypofractionated and ultra-hypofractionated radiotherapy delivered over 20 or 5 treatments are: 1) increased convenience to patients because of fewer treatment days, 2) reduced costs to patients because of reduced travel expenses and copays, 3) improved resource utilization for physicians because of the fewer number of treatments per patient and consequently 4) reduced cost to society. In prostate cancer specifically, hypofractionated and ultra-hypofractionated radiotherapy has the added potential of not increasing toxicity with shorter treatment times.
