My wife has been getting the free Cure magazine for years. They have some articles on prostate cancer treatments and related cancers in the latest issue:https://www.curetoday.com/publications/cure/genitourinary-cancers-special-issue-2020
That also have a prostate guide that provides some good info and references:https://curemagazine.s3.amazonaws.com/_media/_pdf/pc_rg.pdf
I have not seen this referenced previously and it is pretty easy to read unlike many of the papers published. It obviously uses advertisements to pay the bills.
