Prostate cancer prevention
For a disease as common as prostate cancer, a condition which one man in six will be diagnosed with in their lifetime, the ideal approach is to prevent men from getting prostate cancer.
Two clinical trials referred to as the Prostate Cancer Prevention Trial (PCPT) and the subsequent Reduction by Dutasteride of Prostate Cancer Events (REDUCE) trial were conducted over the past two decades. These studies demonstrated that both finasteride and dutasteride (Propecia and Avodart), when used in men between 50 and 75 years of age, reduced the incidence of prostate cancer by 28% and 23% respectively as compared to similar men taking a placebo.
The reduction in the overall incidence of prostate cancer was significant. The use of these drugs and their FDA-approval for prevention has been slow to come in part because of the lingering concern over the high-grade prostate cancer risk. Men in these trials got less prostate cancer if treated with these drugs, but the prostate cancers that they did get were more often high-grade (had higher Gleason scores) and thus appeared to be at risk for behaving more aggressively. Men with a family history of prostate cancer or other high risk factors, and in fact any man, should discuss the use of these drugs for this purpose.
- Vitamin E and selenium were not effective in the prevention of prostate cancer in the SELECT trial. Vitamin E supplementation may have increased the incidence of prostate cancer.
- Lycopene was also ineffective as a preventive agent.
- Pomegranate juice had no meaningful impact on prostate cancer prevention.
- Green tea had some early results suggestive of a possible protective effect, and a larger trial is under way.
- Vitamin D and its derivatives have been studied in prostate cancer. There is no evidence that vitamin D protects against prostate cancer. The vitamin D derivative, calcitriol, has some therapeutic utility against this disease, and is still under study.
Prostate cancer is the most common cancer in men (after skin cancer), and the second leading cause of death from cancer in men. The biology of prostate cancer is better understood today than it was in the past. The natural history of the disease and its staging have been well defined. There are numerous potentially curative approaches to prostate cancer treatment when the disease is localized. Treatment options also exist for prostate cancer that has spread. Ongoing research continues to search for treatments for metastatic prostate cancer.
