What researchers measure

Primary outcomes

  1. To evaluate change in PSA level following 4-9 months of bicalutamide therapy

    Time frame: PSA - 2 measures (at the time of bicalutamdie introduction and 4-9 m following bicalutamide)

Secondary outcomes

  1. bicalutamide prescribing practice based on prostate cancer stage

    Time frame: 1 measure (at the time of bicalutamde th introduction)

  2. to evaluate PSA level after 4-12 weeks of bicalutamide therapy

    Time frame: PSA - 1 measures (1-3 m following bicalutamide)

  3. to asses time to disease progression based on PSA values

    Time frame: PSA - 3 measures (at the time of bicalutamdie introduction, 1-3 m and 4-9 m following bicalutamide)

  4. to evaluate percentage of patients with disease progression

    Time frame: 2 measures at 1st and 2nd visit

  5. to evaluate withdrawals due to adverse events

    Time frame: 2 measures, at 1st and 2nd visit

  6. to evaluate withdrawals due to Croatian Institute for Health Insurance guidelines for bicalutamide prescription

    Time frame: 2 measures, at 1st and 2nd visit
