Poorer outcomes for BRCA1/2 carriers after standard treatment

It is not entirely surprising to come across a paper suggesting that male carriers of the BRCA1/2 genes are at risk for worse post-treatment outcomes than non-carriers of these genes after standard forms of first-line treatment for prostate cancer. … READ MORE …

Rare G84E mutation strongly associated with familial (inherited) prostate cancer

A new study has confirmed an initial finding that the rare G84E mutation (also known as rs138213197) in the HOXB13 gene is a significant driver of risk for prostate cancer among men with a family history of the disease. … READ MORE …

Do SPOP mutations define a new molecular subtype of prostate cancer?

A Letter to the Editor just published in the journal Nature Genetics has suggested that that so-called SPOP mutations may be responsible for between 6 and 15 percent of the prostate cancers diagnosed in the USA each year. … READ MORE …
