The standard of care these days is a drug called docetaxel -- or Taxotere -- for patients who have metastatic disease. Now, this drug can be used throughout all states of the cancer progression for patients who have rapidly rising PSAs in the absence of any demonstrable disease and have failed hormones, or it can be used in patients who have had other treatments as well as radiation or other chemotherapies. When asked about whether there are other chemotherapies for prostate cancer, the current standard of care for patients who have failed hormones is docetaxel (or Taxotere). It's usually given on an every three weeks schedule, well-tolerated and has the usual side effects of possible reduction of the white blood cell count, a little bit of thinning of the hair and maybe a little bit of fatigue and nausea. But again, all amenable to a variety of different medications that can remove the nausea, and, of course, patients are able to continue to do what they normally do.
