Brief Summary:

Radiation therapy is one of the standard treatments for men with prostate cancer who have detectable levels of prostate specific antigen (PSA, a prostate cancer specific marker) after surgery. When radiation therapy is given to patients who have an increase in PSA after surgery, it is called "salvage radiation therapy". Currently the standard radiation therapy course length for this type of cancer is around 7 ½ -8 weeks. Sometimes, radiation therapy after prostate removal causes unpleasant side effects. A shorter course of radiation therapy, known as a "hypofractionated" course, gives fewer but higher doses of radiation than standard radiation.

The purpose of this study is to test the safety of a shorter course of radiation therapy at progressively lower dose levels and shorter lengths of treatment (hypofractionated) with patients who have had their prostate removed. The study will assess whether the hypofractionated course works better without causing additional side effects to the remaining cancer cells in the prostate bed.

Primary Outcome Measures :
  1. Dose limiting toxicity [ Time Frame: over a period of 2 years ]
    Incidence of GU (genitourinary) and GI (gastrointestinal) toxicities of CTCAE (Common Terminology Criteria for Adverse Events) grade 3 or greater

  2. Quality of life measure [ Time Frame: over a period of 2 years ]
    To compare quality of life post-procedure from baseline


Secondary Outcome Measures :
  1. Biochemical failure rate [ Time Frame: over a period of 2 years ]
    A biochemical failure is defined as an increase in prostate serum antigen concentration to nadir plus 2ng/mL or 3 consecutive increases in PSA


Other Outcome Measures:
  1. Acute and late GU and GI toxicity [ Time Frame: over a period of two years ]
  2. Health Utilities [ Time Frame: 1 year after radiation treatment ]
  3. EPIC Prostate Cancer-Specific QOL instrument [ Time Frame: over a period of two years ]
    looking at changes in sexual and hormonal domains

  4. Ancillary financial burden [ Time Frame: over a period of two years ]
    estimating out-of-pocket costs and lost wages for patients during treatment
