Phase II Study of SBRT as Treatment for Oligometastases in Prostate Cancer

This study aims to probe the effect of SBRT as a treatment oligometastases of prostate cancer, regardless of basal treatment received, and I know the response, biochemical control, the progression-free survival as well as their impact on quality of life.

Primary Objective: Local and symptomatic oligometastases Control of prostate cancer treated by SBRT.

Secondary Objectives: Analyzing biochemical progression rates, progression-free survival, chemotherapy-free survival and overall survival. Analyze toxicities and quality of life of patients before and after treatment

Inclusion Criteria:

• Patients with histologically confirmed prostate cancer, who are currently being oligometastases / oligorrecurrencia after primary treatment for their disease.
• Aged ≥ 18 years
• Time to biochemical recurrence more than 1 year
• PSA doubling time> 3 months
• Less than 5 bone metastases location (including spinal) or lymph node.
• Without other metastases or recurrences by Choline PET or / and NMR Diffusion Length.
• Signed and dated written informed consent form.

Exclusion Criteria:

• Patients currently treatment with abiraterone, enzalutamide, chemotherapy, immunotherapy or radioisotopes.
