Primary Outcome Measures
NameTimeMethod
Main Objective: To analyse the safety of oestradiol in the setting of endocrine treatment for locally extended prostate cancer adjuvant to radiotherapy.;Secondary Objective: 1) Analyse compliance to the study intervention (measured by oestradiol serum levels)<br>2) Analyse the incidence of endocrine therapy related side effects<br>3) Analyse changes of metabolic serum parameters<br>4) Analyse time to reach testosterone castration levels<br>5) Analyse quality of Life (EORTC QC 30, PR25 potency, overall);Primary end point(s): Incidence of cardiovascular events (number of cardiovascular events per 100 person years).;Timepoint(s) of evaluation of this end point: Continuous
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): 1) Compliance to the study intervention (measured by oestradiol serum levels at every visit).<br>2) Incidence of endocrine related side effects.<br>3) Changes of metabolic serum parameters (liver function (SGOT, SGPT, bilirubin), endocrine (oestradiol, testosterone, PSA), lipid profile (HbA1c, cholesterol, HDL).<br>4) Time to reach testosterone castration levels (during run-in period, T = 1.7 nmol/L).<br>5) Quality of Life (EORTC QC 30, PR25 potency, overall).;Timepoint(s) of evaluation of this end point: Continuous.
