Does BPH Treatment Protect Against Cancer Deaths?

Use of 5-ARIs and risk of prostate cancer mortality

In men with a new diagnosis of prostate cancer, 5a-reductase inhibitors (5-ARIs) are not associated with an increased risk of prostate cancer specific or all-cause mortality, a retrospective cohort study of 13,893 men reports.

Researchers estimated hazard ratios (HR) for prostate cancer-specific and all-cause mortality associated with prediagnostic use of 5-ARIs and found an overall crude incidence rate of 3.86 deaths per 100 person years. When stratified by use and non-use of 5-ARIs, the crude incidence rates per 100 patient years are as follows:

use

non-use

aHR

Prostate cancer-specific mortality

3.76

3.87

0.86

All-cause mortality

8.42

7.93

0.87
