In June, the US Food and Drug Administration (FDA) launched an accelerated review of a promising new drug for advanced prostate cancer. Called relugolix, it suppresses testosterone and other hormones that speed the cancer’s growth. If approved, this new type of hormonal therapy is expected to set a new standard of care for the disease. […]

Defective BRCA genes are well known for their ability to cause breast and ovarian cancers in women. But these same gene defects are also strong risk factors for aggressive prostate cancer in men. About 10% of men with metastatic prostate cancer — meaning cancer that is spreading away from the prostate — test positive for […]

Are prostate cancer biopsies reliably accurate? Not always. The most common method, called a systematic biopsy, sometimes misses tumors, and it can also misclassify cancer as being either more or less aggressive than it really is. During systematic biopsy, a doctor takes 12 evenly-spaced samples of the prostate, called cores, while looking at the gland […]

Treatments for prostate cancer are always evolving, and now research is pointing to new ways of treating a cancer that has just begun to spread, or metastasize, after initial surgery or radiation. Doctors usually give hormonal therapies in these cases to block testosterone, which is a hormone that makes the cancer grow faster. But newer […]

Prostate cancer therapies are improving over time. But how do the long-term side effects from the various options available today compare? Results from a newly published study are providing some valuable insights. Investigators at Vanderbilt University and the University of Texas MD Anderson Cancer Center spent five years tracking the sexual, bowel, urinary, and hormonal […]

Last year, we reported on two studies showing that African American men respond at least as well as white men to prostate cancer treatments given in clinical trials. Nationally, African Americans with prostate cancer are more than twice as likely to die of the disease as their white counterparts, and that has fueled speculation that […]

Prostate cancer screening with the prostate-specific antigen (PSA) test has been criticized for flagging too many slow-growing tumors that might never be life-threatening. But some men have inherited gene defects that boost their risk of developing prostate cancers that can be quite aggressive. Is PSA screening particularly well-suited for these genetically defined groups? New research […]

Treatments for advanced prostate cancer that suppress testosterone, a hormone (also called an androgen) that drives the malignant cells to grow and spread, are collectively referred to as androgen deprivation therapies, or ADT. These therapies can significantly extend lifespans in men who have the disease, but they also have a range of challenging side effects. […]

If a man has an enlarged prostate, there’s a good chance he’ll be treated with a type of drug called a 5-alpha reductase inhibitor (5-ARI). These drugs shrink the gland to improve urinary flow, and the approved forms used for treating enlarged prostates come in two varieties: Proscar (finasteride) and Avodart (dutasteride). However, a side […]

By now most of us are familiar with Brexit, the UK’s pending divorce with the European Union. But in a play on that term, British doctors are also moving towards an exit they’ve dubbed “TRexit” from the most common sort of prostate biopsy: the transrectal ultrasound guided biopsy, or TRUS. Men who test positive on […]
