Susan, yes, these are biomarkers of bone breakdown and cancer spread. ALP (bone specific variety) is alkaline phosphatase. Don's was up this month despite dropping slightly last month. However, he is on prednisone 5mg bid, and this can cause a slight rise. He started the pres two weeks ago. The LDH is lactate dehydrogenase and it is crazy high. It can represent cellular damage so I am hoping that this and the doubling PSA is due to cancer cell lysis, although this is a big hope! That reminds me, I should check to see if the uric acid and K are also elevated, which would support that theory. We have emailed Dr. Myers (I think he must be away somewhere as we haven't heard a bean for two weeks). Dr. Barken is onto it of course and we will be discussing it with him today. Re the PET scan, I really don't know how it works in the US with insurers. We would have to pay out of pocket. Our house will be going on the market in a couple of months so that we can find a smaller one and pay for all these tests and treatments. That might include the prostate being removed...we shall see. Dr. Strum has just got back to us on the bone breakdown issue. Wants Don to have a higher Xgeva dose I think so I will check this and let everyone know. His DpD test was 9.9 - way too high.
Sue, Dave and Quincy, Connie, have a good weekend as well.
