Brief Summary
The aim of the study is to compare in an exploratory fashion the efficacy on progression-free survival of lanreotide in addition to non steroidal anti androgens and LHRH-a in non metastatic castrate resistant prostate cancer patients.

EXPERIMENTALInterventions
Lanreotide 120 mg. Injection every 28 days, to be administered till progression or for a maximum of 24 months. Non steroidal anti androgens (e.g. bicalutamide 50 mg/day to be administered till progression) plus LHRH-a (e.g. triptorelin 3.75 mg/month till progression.
Non steroidal anti androgens (e.g. bicalutamide 50 mg/day to be administered till progression) plus LHRH-a (e.g. triptorelin 3.75 mg/month till progression
Eligibility Criteria
You may qualify if:
- Histologically proven diagnosis of prostate cancer
- Evidence of PSA progression despite castrate levels of testosterone (\<50 ng/dL) following orchiectomy or during therapy with luteinizing hormone releasing hormone agonists (LHRH-a)
- Patients with non-metastatic or stable metastatic disease
- Chromogranin A elevation above normal range (confirmed by a second evaluation at least 1 week later) \[cut off levels will be \> 20 U/L for enzyme linked immunosorbent (ELISA) assay and \> 100 ng/ml for immunoradiometric (IRMA) assay\]
You may not qualify if:
- Patients who according to the investigator opinion are candidates to be treated immediately with chemotherapy (e.g. docetaxel)
- First line treatment with antiandrogen in monotherapy
- Visceral metastasis
- Previous or concomitant treatment with a somatostatin analogue
