Reporting Groups
  Description
Advanced Prostate Cancer Participants Participants with advanced prostate cancer treated with Lucrin /Lucrin- Tri-depot (leuprolide) or any other treatment with local reimbursement guidelines. No Baseline data was available for 3 patients who were thus excluded from all analyses.

Reporting Groups
  Description
Advanced Prostate Cancer Participants Participants with advanced prostate cancer treated with Lucrin /Lucrin- Tri-depot (leuprolide) or any other treatment with local reimbursement guidelines. No Baseline data was available for 3 patients who were thus excluded from all analyses. Age was available for 2,691 patients only; age was missing for 23 patients who were thus not included in the age results.
