Outcome Measures
Primary Outcomes (2)
Progression-free Survival (PFS) Defined as the Time From Patient Recruitment to Biochemical Progression Based on Doubling of Prostate Specific Antigen (PSA) Velocity or PSA > 5.0
PFS defined as the time from patient recruitment to biochemical progression based on doubling of prostate specific antigen (PSA) velocity or PSA \> 5.0, objective tumor progression (RECIST criteria), or death. The distribution of PFS was estimated using Kaplan-Meier methodology. The point estimate and standard error (SE) of the distribution are provided.
36 months
Progression-free Survival (PFS) Defined as the Time From Patient Recruitment to a Change to an Absolute Value of PSA > 2 ng/mL on at Least 2 Consecutive Tests
A second definition of PFS was used due to changes in the definition of biochemical progression: the time from patient recruitment to a change to an absolute value of PSA \> 2 ng/mL on at least 2 consecutive tests, objective tumor progression (RECIST criteria), or death. The distribution of PFS was estimated using Kaplan-Meier methodology. The point estimate and standard error (SE) of the distribution are provided.

Study Arms (1)
Patients with Prostate Cancer
Patients with prostate cancer who were receiving treatment with leuprolide acetate (Lupron).
Eligibility Criteria
Patients will be enrolled from the offices of university or community urologists/oncologists across Canada treating patients with PCa.
You may qualify if:
- Has provided written informed consent allowing the use of their data for the study and providing permission for contact by the study personnel
- Diagnosed with Prostate Cancer
- Prescribed Lupron as part of his treatment by his treating physician
You may not qualify if:
- Currently participating in another prospective study including controlled clinical trials and observational studies.
- Patient cannot or will not sign informed consent
- Survival expectancy less than 2-3 years as per the treating physician's judgment
- Presence of other condition that, in the opinion of the treating physician, prohibits the patient from participating in the study or obscures the assessment of the treatment of Prostate Cancer
- History of alcohol or drug abuse
- No longer than 6 months of therapy if currently on luteinizing hormone-releasing hormone (LHRH) treatment

Limitations and Caveats
This was a real-world evidence assessment with clear limitations. One of the key limitations of the study was that treatment patterns were not fully documented. Furthermore, compliance/adherence may have impacted efficacy data.
