Sure enough, we showed up on Monday morning at 8:00 am and they had no treatment scheduled. The nurse said they never do more than 5 days of treatment of Vidaza. We had never heard of this! Our bone marrow doctor in Cleveland told us it would be a 7 day treatment, 5 days one week and two the next week.
The nurse waited until the local oncologist came in to ask him what he was going to do. Meanwhile, I called Cleveland Clinic to ask them what treatment had been prescribed. They said usually the treatment is 7 days, but that some doctors do 5.
By this time the nurse had returned with orders from the local oncologist saying she was to go ahead and give it to him if that is what the doctor at Cleveland said to do. This isn't the first problem we've had with the local oncologist. (I will write a separate post about this).
I relayed this to Cleveland and they said to do the seven days if he is going to administer it.
Being the first time we had heard of a five day treatment, I decided to Google it. My favorite "go to" source, the MDS Beacon, came up with a story dated May 2013 that spoke of a study conducted in Portugal where the treatment center used 5- day treatments because of limited staff scheduling. While the study didn't find the 5-day treatment to be necessarily inferior, it is NOT the recommended treatment regimen in the United States or Europe, nor is was there enough data at that time to recommend a 5-day treatment over the 7-day standard. (O'Reilly, McHale, et al, as cited in Engle and Haehle np).
Gillian Lush, another writer of the MDS Beacon, wrote in 2009 about a information submitted by Garcia, de Miguel, and Bailen, et al. where "three different dosing schedules were studied, each on a 28-day cycle." It was found that:
Todd's treatment regimen would be considered: Treatment on days 1-5, 8 and 9. This is done because facilities are not open for treatment on Saturdays and Sundays, which would be considered days 6 and 7.
I'm not saying that there is more evidence, trials, or published studies that the Kettering doctors relies on that I haven't read, because he obviously may know more that I don't. However, looking at these two studies from a layman's point of view, we chose to stick to our guns and insist on seven days of treatment. If he is going to go through all the sickness and side-effects of the Vidaza, he might as well go for the treatment with the better results.
In addition to treatment, they finally drew Todd's blood to review his counts. They are supposed to check your blood work every three days, but for some reason, this was the first time in six days that they took his blood. His platelets were about the same, but still low. His white counts had dropped quite a bit, but this is usually expected as a side-affect of the chemotherapy.
After treatment, he got out for a bit and then went home to rest. He is still having issues with digestion and nausea, but they did give him the Aloxi today, which we hoped would be a big help. He has lost weight and I'm still pushing him to eat whenever I can.
Tomorrow will the last treatment for now.

"Of the three groups, the overall response rate of group C (who had 7 days of consecutive treatments)was the highest at 74 percent. Group A (5 day only treatment) showed a response rate of 58 percent, and group B (who received Vidaza on days 1, 2, 3, 4, 5, 8, and 9) showed a response rate of 65 percent." (Lush n.p. Parenthetical statements added).
