Study Arms (2)
Conventional Fractionated Radiation
ACTIVE COMPARATOR* Prostate Only Radiation - 37.5Gy in 15 daily fractions to the prostate and proximal/entire seminal vesicle * Prostate + Nodal Radiation - 46Gy in 23 daily fractions to the prostate, seminal vesicle and regional lymph nodes
Stereotactic Body Radiotherapy
EXPERIMENTAL* Prostate Only Radiation - 25Gy in 5 fractions to the prostate and proximal/entire seminal vesicle * Prostate + Nodal Radiation - 25Gy in 5 fractions to the prostate, seminal vesicle and regional lymph nodes
Interventions
Hypofractionated stereotactic radiation treatment.
External beam radiation therapy treatment
Eligibility Criteria
You may qualify if:
- Age 18 or older
- Informed consent for treatment and study participation completed
- Pathologically proven diagnosis of prostate adenocarcinoma
- ECOG Performance Status 0-2
- No prior history of pelvic radiotherapy, brachytherapy, cryosurgery, HIFU, TURP or radical prostatectomy
You may not qualify if:
- Presence of nodal or distant metastasis on staging MRI or CT Abdomen/Pelvis and Bone scan within 90 days of enrolment (CT/MRI/Bone Scan are only required if the clinical risk of metastatic disease is sufficient to warrant these scans)
- Plan for adjuvant chemotherapy post-radiotherapy
- Serious medical comorbidities or other contraindications to HDR brachytherapy
- Presence of inflammatory bowel disease
- Presence of connective tissue disorder seen as a contraindication to radiotherapy
- Medically unfit for general/spinal anesthesia
- Unable or unwilling to complete questionnaires
