Disappointing Test Results

Thursday, May 27, was the end of Cycle 29 of my pomalidomide (CC-4047) trial at Mayo Clinic. Unfortunately, my IgG and M-spike were both up about 10%, which is not good news. Every myeloma regimen fails eventually, and this could signal the end of my rather easy ride on pomalidomide. Furthermore, the neutrophil count is 920 (tiny buggers per microliter) and if it stays below 1000 I can't continue on the pomalidomide study until it goes back up. Otherwise, in theory at least, I'm a little too vulnerable to bacterial and fungal infections.

Neutrophils:

My Mayo blood draws are usually ay 6:30 am, and the neutrophil count was below 1000 at the end of both of the previous two cycles. In an afternoon blood draw a few days later, in both cases, the count had jumped up well above 1000 and I was able to continue on the study. This time, though, I was heading out of town to run a marathon, so we did another blood draw at Mayo before I left, still in the morning but not so early, hoping that it would show 1000 or above. But the vaunted Mayo Clinic screwed up! They did the CBC, but failed to do the differential which shows the actual absolute neutrophil count. By the time we discovered this, the test could not be repeated and we were almost halfway from Minnesota to Idaho. So the next day we stopped in Billings, MT, and had blood drawn there. I do not yet know the results of that CBC, so I can't be sure of continuing on the study. I'll assume the best unless I hear from Mayo.

Genistein:

I have been taking genistein, a soy isoflavone, throughout the pomalidomide trial, about 50 mg/day. It is supposed to have some anti-cancer effects by "supporting" the immune system. However, since myeloma is a cancer OF the immune system, there is a question whether it should be "supported," and in addition there are other questions about any estrogen-simulating supplement. So I decided to stop it for a cycle, to see what might happen to IgG and M-spike. I guess I got my answer. Back on genistein!

Hand Infection:

Three months ago I whacked the back of my left hand against something and got an infection, either bacterial or fungal, and the hand eventually got quite warm, swollen, and painful. It has healed very slowly, but it's almost better now.

Some current test results:

ASCO Conference:

I have been invited to attend the annual meeting of the American Society of Clinical Oncologists next week, and I will be blogging in "real time" about the presentations that I see there. Here are a few of the topics that seem interesting to me: Related links:

I haven't had time to update the charts, test results table, and other documents (see links above) that go with this post, but wanted to get this posted now when I have a few minutes. I'll get around to the rest later, but there is really not a lot of change except the increase in IgG and M-spike.
