Introduction:
If an agent can slow the growth of existing prostate cancer cells, it remains plausible that it may be effective as an adjunct to surgery, radiation or chemotherapy.
Discussion:
Level-1 evidence will be needed in order to definitively prove the efficacy of agents as chemoprevention strategies for prostate cancer. Currently, only finasteride fulfills this criterion. Two major trials are underway that will assess the role of soy, vitamin E and selenium in prostate cancer prevention.
Conclusion:
Tantalizing prospects for effective chemoprevention of prostate cancer exist. Fortunately, well-conducted randomized trials will allow us to answer many of these questions within the next 2 to 8 years.
Insights
Agents that slow prostate cancer growth show promise for prevention. While finasteride is the only proven agent, ongoing trials will clarify the roles of soy, vitamin E, and selenium in prostate cancer chemoprevention.
Area of Science:
- Oncology
- Urology
- Preventive Medicine
Background:
- Agents slowing prostate cancer cell growth may serve as adjuncts to standard treatments like surgery, radiation, or chemotherapy.
- The potential for chemoprevention strategies in prostate cancer management is an active area of research.
Purpose of the Study:
- To evaluate the efficacy of various agents in preventing prostate cancer.
- To identify agents that can be used as chemoprevention strategies for prostate cancer.
Main Methods:
- Review of existing evidence on prostate cancer chemoprevention.
- Identification of agents with demonstrated effects on prostate cancer cell growth.
- Highlighting ongoing randomized trials assessing chemoprevention agents.
Main Results:
- Currently, only finasteride meets the criterion for Level-1 evidence in prostate cancer chemoprevention.
- Several agents, including soy, vitamin E, and selenium, are under investigation.
Conclusions:
- Effective chemoprevention strategies for prostate cancer hold significant promise.
- Well-designed randomized trials are crucial for definitive evidence and are expected to yield results within 2 to 8 years.
