Finasteride News and Research

RSS

Finasteride is a synthetic antiandrogen which acts by inhibiting type II 5-alpha reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT). It is used as a treatment in benign prostatic hyperplasia (BPH) in low doses, and prostate cancer in higher doses. Finasteride competitively binds to and inhibits steroid type II 5-alpha-reductase in the prostate gland, liver, and skin, thereby interfering with the enzymatic conversion of testosterone to 5-dihydrotestosterone (DHT) and reducing serum DHT levels. The reduction in serum DHT levels results in diminished stimulation of androgen receptors in the nuclei of prostate cells and, so, diminished prostate cell proliferation.

Prostate cancer: current evidence weighs against population screening

The recent release of two large randomized trials suggests that if there is a benefit of screening, it is, at best, small, says a new report in CA: A Cancer Journal for Clinicians.

Selenium and vitamin E supplements do not prevent prostate cancer

Initial, independent review of study data from the Selenium and Vitamin E Cancer Prevention Trial (SELECT), funded by the National Cancer Institute (NCI) and other institutes that comprise the National Institutes of Health shows that selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer.

Finasteride for prostate cancer

A comprehensive re-evaluation of the largest prostate cancer prevention study ever completed produced new findings suggesting that men and their doctors should consider a more aggressive approach that includes finasteride to prevent the development of prostate cancer.

Five-alpha-reductase Inhibitors for prostate cancer prevention

Compared to placebo treatment, taking 5-alpha-reductase inhibitors (5-ARIs) can reduce a man's risk of being diagnosed with prostate cancer from around 5-9% to around 4-6% during up to 7 years of treatment, according to a new Cochrane Review.

Diet and medications may assist prevention of prostate cancer

Recent investigations of medications, diet and the molecular understanding of prostate cancer are defining potential prevention strategies for the disease, and herald a new stage in the management of this cancer, according to a new review.

Shrinkage of prostate led to overestimation of cancer risk in finasteride trial

Reanalysis of data from the first long-term randomized trial of a chemopreventive agent for prostate cancer shows that the excess prevalence of high-grade prostate cancer in the drug-treated group may be attributable to shrinkage of the prostate at the time of biopsy.

Generic prostate drug finasteride helps find high-risk cancers early

Men now have another good reason to consider taking finasteride, a well-known generic drug that shrinks an enlarged prostate and reduces the risk of getting prostate cancer by 25 percent.

Finasteride unlikely to induce high grade prostate cancers

An increase in high-grade prostate cancer among men taking the drug finasteride is likely caused by an increased detection of cancers, and not by the development of more high-grade cancers, according to two studies published online September 11 in the Journal of the National Cancer Institute.

Finasteride will cause little or no sexual dysfunction for most men who decide to take it

Men and their physicians need not hesitate to use a drug proven effective in preventing prostate cancer out of concern that it is likely to cause sexual dysfunction, say authors of a study conducted by the Southwest Oncology Group.

A review of PSA use in screening for prostate cancer

Screening for prostate cancer using prostate specific antigen (PSA) testing continues to be problematic. Even though it is unproven whether population-wide screening with PSA can reduce death, illness or disability from prostate cancer, testing has become common in North America.

No single PSA level ensures safety from prostate cancer risk

Ian M. Thompson Jr., M.D., professor and chair of urology at the U T Health Science Center, is looking for a better test - or set of tests - to diagnose prostate cancer and to distinguish between cancers that will kill men if left untreated and those that will not threaten health and do not need treatment.

Finasteride prevents prostate cancer

Recent finding show lives could be saved if men are given the drug Finasteride to prevent prostate cancer. New analysis of data from the Prostate Cancer Prevention Trial in the current issue of CANCER confirms this view. These results represent a milestone in cancer research, showing that prostate cancer could be prevented through drugs.
