Primary Outcome Measures

Name	Time	Method
Main Objective: Main objective is the comparison of the analgesic efficacy of the association zoledronic acid and 153Sm-lexidronam versus zoledronic acid for the treatment of bone pain associated to prostatic cancer.;Secondary Objective: Secondary objectives are: a) the performance of the two drugs in study by means of indicators that describe actions applied by the physician as variations of opioid dosage, switch of drugs, resort to rescue therapies, prescription of other analgesic drugs, interruption of the therapy or exit the protocol; b) incidence of correlates skeletal events; c) correlation between response and bone metabolism markers and PSA; d) safety and tolerability of the treatment observing adverse reactions to drugs, adverse events, adverse serious events and evaluating bone marrow adsorbed doses.;Primary end point(s): Primary endpoint is represented by patients ratio that will be classified as non-responders to the therapies in study;Timepoint(s) of evaluation of this end point: 60 days

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): 1) Evaluation of the first impact of the treatment in controlling bone pain; 2) Subject ratio that needed an increase of the opioid dosage >=5%; 3) Subject ratio that needed an additional treatment; 4) Subject ratio that needed adjuvant analgesic drugs; 5) Subject ratio that needed switch of opioid; 6) Subject ratio that exit protocol because of the treatment.;Timepoint(s) of evaluation of this end point: 1) 15 days 2-6) 60 days
