Eligibility Criteria
Inclusion
- Age ≥ 18 years.
- ECOG 0-1 status.
- Previous radical prostatectomy (any modality will be allowed) with or without lymphadenectomy.
- Histological confirmation of prostate adenocarcinoma in the prostatectomy specimen.
- pT2-T3 Version 2.0, March 27, 2019
- pN0-Nx
- Indication of postoperative RT:
- Adjuvant RT: pT3 and / or positive margins with PSA \<0.2 ng / ml. Delayed RT is considered (\> 6 months from the date of surgery but PSA \<0.2 ng / ml).
- Rescue RT: exclusive biochemical recurrence, without evidence of macroscopic local, regional or distant disease, after surgery. Biochemical recurrence is considered PSA ≥ 0.2 ng / ml after undetectable levels, confirmed with a subsequent determination.
- PSA levels ≤ 2 ng / ml after, at least 45 days after surgery and 30 days before inclusion in the study.
- No clinical evidence of lymph node disease. The presence will be admitted by imaging tests of pelvic nodes ≤ 1 cm in its shortest axis.
- No evidence of disease in the prostatic fossa. If you doubt by digital rectal examination or CT, an MRI will be performed.
- No evidence of distant disease after performing a thoraco-abdominal-pelvic CT scan and bone scan.
- Reasonable follow-up possibilities.
- Ability to complete the EPIC-26 questionnaire.
- Written informed consent prior to inclusion in the study.
Exclusion
- \- Previous pelvic radiation therapy.
- Distant metastasis.
- Macroscopic residual tumor.
- PSA\> 2 ng / ml.
- Pathological stage T4.
- Lymph node involvement.
- Pelvic or para-aortic nodules in the reevaluation images after surgery, except pelvic nodes ≤ 1 cm in their shortest axis.
- Indication of pelvic nodal RT. Version 2.0, March 27, 2019
- Severe urinary incontinence at the time of indication for radiotherapy.
- Uni / bilateral hip prosthesis
- Previous tumors, except non-melanoma skin carcinoma, and which are not free of disease for at least 3 years from the end of the treatment of said neoplasms. Bladder tumors are excluded in all cases.
- Genetic hyper-radio-sensitivity syndromes.
- Chronic inflammatory bowel disease or partial or radical cystectomy for any reason.
- Previously treated with androgen deprivation therapy for a period greater than 3 months.
- Previously treated with chemotherapy for prostate cancer.
- Life expectancy \<5 years or severe comorbidity: unstable angina, congestive heart failure, transmural myocardial infarction requiring admission in the last 6 months, active infectious process, respiratory disease requiring hospitalization, liver failure (Child-Pugh Class B or C), HIV with a CD4 count \<200 cells / ml, kidney failure requiring dialysis and immunosuppressed by other causes.
