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

Stereotactic Body Radiation Therapy for Oligometastases (SBRT)
Radiation: Stereotactic Body Radiation Therapy for Oligometastases
- Number of patients without disease progression of prostate cancer treated by SBRT [ Time Frame: 5 years ]Number of patients without disease progression of local and symptomatic oligometastases of prostate cancer treated by SBRT expressed as total number and percentage
- Overall Survival measured with Kaplan-Meier method [ Time Frame: patients will be followed up an average of 5 years ]the time to death will be defined as the time between the date when the patient is treated with SBRT and the date of death, or the last follow-up visit.
- Number of patients with an adverse events. [ Time Frame: 3 months after the SBRT treatment ]Analyze toxicities in every patient during the first 3 months after the treatment with SBRT. Every significant Adverse Event will be graded as CTC-AE v.4.03. For Pain related adverse events, visual analogic scale (VAS) will be used.
- Free disease progression survival measured with Kaplan-Meier method [ Time Frame: the patients will be followed up an expected average of 5 years ]the time to disease progression will be defined as the time between the date when the patient is treated with SBRT and the date of biochemical (PSA increased upper to 2 ng/mL) o radiological progression or the last follow-up visit.
- Quality of life questionnaire FACT-P [ Time Frame: baseline and 3rd month after the SBRT treatment. ]The Functional Assessment Of Cancer Therapy-Prostate Questionnaire (FACT-P) will be performed at baseline and 3 months after the SBRT treatment.
