Researchers Develop System that Finds Prostate Cancer Metastases Earlier

Researchers at UCLA’s Jonsson Comprehensive Cancer Center have developed a way to image the spread of a dangerous form of prostate cancer earlier than today’s conventional imaging techniques. The new method may allow oncologists to find and treat metastases more quickly and give patients a better chance at survival.

The gene-based imaging system targets castration-resistant prostate cancer, an aggressive form of the disease that has become resistant to the hormone treatment known as androgen-deprivation therapy. Once this treatment no longer works, the cancer will progress within 12 to 18 months, and the prognosis becomes grim, said senior study author Dr. Lily Wu, a professor of molecular and medical pharmacology and a Jonsson Cancer Center researcher.

*Researchers urge appropriate use of androgen deprivation therapy* 

ANN ARBOR, Mich. — Men treated with hormone-based therapy for prostate cancer faced a 30 percent to 40 percent higher risk of colorectal cancer, compared to patients who did not receive this treatment, according to a new study. 

The study looked at use of androgen deprivation therapy, a common type of treatment for prostate cancer that involves blocking the male hormone testosterone through either surgical removal of the testicles or a series of injections. It’s been shown to benefit men with advanced cancers, but its benefit for less-advanced disease is unclear. Still, more than half a million men in the United States currently receive this therapy.  (more…)
