You are in luck! One of the premier active surveillance programs is at Memorial Sloan Kettering Cancer Center (MSKCC) in NYC.
The MSKCC Active Surveillance (AS) program has been going on for many years, and my impression is that the driving force behind it is the highly respected prostate cancer surgeon Peter Scardino, MD. At times MSKCC researcher/physician teams publish snapshots of results, and you can access them the same way medical professionals do using our taxpayer supported National Library of Medicine online, which we can mention on this board because it is government supported (PubMed, for Public Medicine, at www.pubmed.gov). I just used this search string (ignoring the quotation marks) " active surveillance AND scardino pt [au] ". That resulted in 13 hits. By clicking on the blue hypertext titles, you can view the abstract of any paper if there is one. Moreover, the list of 13 included free links to two complete papers.
Of course you can try other searches for yourself. Use AND in caps to connect search terms (or OR, NOT), and use quotation marks if you want exact words to be searched. You can have several ANDs. Use [au] after authors names, and use [dp] after publication years. There's more to it than that if you want to get more sophisticated, but you can learn a lot from simple searches.
