About this trial
This is an interventional treatment trial for Prostatic Neoplasms, Locally Advanced focused on measuring Drug Therapy, Radiotherapy
Eligibility Criteria
Inclusion Criteria:

- Patient for whom a recent blood test (less than [<] 2 months) has not revealed elevated transaminases ≥ 3 times the normal laboratory range.
Exclusion Criteria:
- Patient incapable of understanding the information supplied concerning the study or of giving his consent, or having refused to sign the informed consent form,
- Patient for whom there is a risk that follow-up in compliance with the conditions stipulated by the protocol will not be possible,
- Patient having already received prior treatment for prostate cancer, excluding transurethral resection of the prostate to relieve obstruction,
- Patient having undergone surgical castration, or with a history of bilateral adrenalectomy or hypophysectomy,
- Patient having had another cancer within the previous 5 years (including carcinoma in situ of the bladder) excluding basocellular epithelioma or carcinoma in situ (other than in the bladder),
- Patient with lymph node or metastatic spread of the prostatic adenocarcinoma suspected on imaging,
- Patient with a non-controlled severe active disease,
- Patient with a contraindication to external prostatic radiotherapy,
