Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hypofractionated radiation
40 Gy in 5 fractions over 29 to prostate; 30 Gy in 5 fractions over 29 days to seminal vesicles
Radiation: Hypofractionated radiation
40 Gy in 5 fractions to prostate, 30 Gy in 5 fractions to seminal vesicles; total treatment duration 29 days
Other Name: RapidArc

Detailed Description:

Primary Endpoints:

  • Acute gastrointestinal (GI) and genitourinary (GU) Common Terminology Criteria for Adverse Events (CTCAE) v3.0 toxicities

Secondary Endpoints:

  • Late GI and GU Radiation Therapy Oncology Group (RTOG) toxicities
  • Biochemical disease-free survival
  • Biopsy positive rate at 3 years
  • Quality of life using the Expanded Prostate Cancer Index Composite (EPIC) questionnaire
  • Develop a biobank of DNA and serum extracted from blood and urine to analyze and develop new biomarkers for prostate cancer progression or susceptibility to severe toxicity
  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • informed consent obtained
  • men > 18 years
  • histologically confirmed prostate adenocarcinoma (centrally reviewed)
  • high risk prostate cancer, defined as at least one of: clinical stage T3, or gleason score 8-10, or PSA > 20ng/mL

Exclusion Criteria:

  • prior pelvic radiotherapy
  • anticoagulation medication (if unsafe to discontinue for gold seed insertion)
  • diagnosis of bleeding diathesis
  • pelvic girth > 40cm (to ensure visibility of gold seeds on electronic portal imaging)
  • large prostate (> 90cm3) on imaging
  • severe lower urinary tract symptoms (International Prostate Symptom Score >19 or nocturia > 3)
  • No evidence of castrate resistance (defined as PSA < 3ng/mL while testosterone is < 0.7nmol/L). Patients could have been on combined androgen blockade but are excluded if this was started due to PSA progression
