From the Guidelines
The treatment duration required for the best outcome with 5-alpha-reductase inhibitors, such as finasteride, for the prevention of prostate cancer is 7 years, as evidenced by the Prostate Cancer Prevention Trial (PCPT) 1. This recommendation is based on the most reliable trial directly comparing the benefits and harms of finasteride in the target population for interventions to prevent prostate cancer. The PCPT, which administered finasteride for a planned 7 years, provides the strongest evidence for the efficacy of 5-alpha-reductase inhibitors in preventing prostate cancer 1. While other trials, such as the Medical Therapy of Prostatic Symptoms (MTOPS) and the Finasteride Study Group, have investigated the use of 5-alpha-reductase inhibitors for shorter durations, the PCPT remains the most relevant study for determining the optimal treatment duration for prostate cancer prevention 1. Key points to consider include:
- The PCPT demonstrated a significant reduction in the risk of prostate cancer with 7 years of finasteride treatment 1.
- Other trials have shown varying results with shorter treatment durations, but the PCPT provides the most robust evidence for long-term treatment 1.
- The use of 5-alpha-reductase inhibitors for prostate cancer prevention should be individualized, taking into account the potential benefits and harms, as well as the patient's overall health and risk factors 1. Some potential side effects of 5-alpha-reductase inhibitors, such as finasteride, include impotence, decreased libido, and gynecomastia, which should be carefully considered when weighing the benefits and risks of treatment 1. In terms of specific dosing regimens, the PCPT used a daily dose of 5 mg of finasteride, which is the recommended dose for prostate cancer prevention 1. Ultimately, the decision to use 5-alpha-reductase inhibitors for prostate cancer prevention should be made in consultation with a licensed healthcare provider, who can provide personalized guidance and monitoring throughout the treatment period 1.
