Rising PSA

My PSA is rising after prostate cancer surgery 21 months ago. Androgen Deprivation Therapy helps but is not entirely successful. My most recent PSA was 2.2. I am still too well for more radical treatment. Are there any trials out there for rising PSA at low levels? Are there any trials to deal with the DHT which fuels these androgen resistant cells? Just wondering. I would rather try stuff now rather than wait for it to progress.

What ADT routine are you on? What are your testosterone levels? They need to be below 30 for the full effectiveness of the ADT to be realized. Avodart is often part of ADT and attacks the DHT. Often the PCa specialists will use ADT3 by combining Lupron/Eligard, Casodex, and Avodart/Proscar. Usually this is the strongest combination. Some are introducing a chemotherapy (usually Taxotere) earlier in conjunction with ADT for high risk patients. Are you with an oncologist that specializes in PCa? The fact that your PSA is rising while on ADT is troubling and could indicate that you are becoming refractive.
