Aim: The aim of this paper was to compare and analyze the therapeutic effects and PSA variation levels with treatment with finasteride-tamsulosin and dutasteride-tamsulosin for benign prostatic hyperplasia for 2 years and the risk to developing prostate cancer for patients with PSA<4 ng/mL.
Methods: We retrospectively investigated 288 patients who suffered from BPH and PSA>4 ng/mL between January 2003 and July 2010. For treatment groups, we divided the patients into two groups: one was treated with tamsulosin and finasteride and the other with tamsulosin and dutasteride. At the beginning of treatment, the patients underwent transrectal ultrasonography and prostate mapping, measurement of urine flow rate, PSA, and International Prostate Symptom Score (IPSS). A total of 288 patients were able to be.
Results: Both finasteride and dutasteride rduced PSA and prostate volume significantly. The comparison between the 2 groups showed a significant difference at 3 months for IPSS; uroflussimetry and prostate volume in the dutasteride group, but at 6 months did not differ significantly between the groups. Patients with a PSA reduction more than half presented a good response and didn’t request surgical theraphy.
Conclusion: 5 alpha Reductase inhibitors for BPH treatment reduced PSA and prostate volume significantly after 6 months of theraphy and after 3 months only for dutasteride. PSA reduction is directly correlated with response to theraphy. Didn’t were evidenced statistically differences on prostate cancer presence during theraphy.
