Reduced Intensity Conditioning (RIC) vs Myeloablative (MA)
I was under the impression I was going to receive Reduced Intensity Conditioning (RIC) prior to my stem cell transplant. My doctor later told me that I had received Myeloablative (MA) conditioning. From the following does anyone know exactly which I got? I believe the Total Body Irradiation was a total of 5 Gray.
____________________________________________________________ Cytarabine will be given daily through your central venous catheter (IV) continuously for 5 total days. Cyclophosphamide (Cytoxan) willl be given once a day through your catheter (IV) over approximately 2 hours for two (2) consecutive days. Total Body Irradiation (TBI) will be administered once prior to your transplant. ____________________________________________________________ Thanks Data |
Data,
Having only one day of TBI seems to imply that it was RIC, not MA conditioning. Compare the regimens in this chart from this article and you'll see typical differences. 5 Gray is more than the typical RIC dose, but well below the typical MA dose. Can you match your treatment to one of the regimens shown? |
Nice chart
Neil,
I couldn’t find an exact match in the chart but the Cyclophosphamide (Cy), Cytarabine (ARA-C), and TBI seemed to be used more often in the Myeloablative Regiments. The dosage for the TBI did seem low in my case but then I can’t remember for sure what the dose was. I don’t have any records that state what the dosage was. I do have the records that say it was going to be RIC and what drugs were given to me and for how long. The main reason I got to thinking is was myeloablative was the doctor had said it was on a couple of occasions but I don’t really trust him because he has changed what he said on several occasions. Thanks again for your comments. Data |
Data,
I reviewed several articles on RIC vs MA and it appears that your dosing levels of ARA-C and CY would be the determining factors. It kind of looks like your doctor split the difference a bit. There are a few studies out of Germany and MD Anderson that used cytarabine as part of RIC. I did not see anything that matched your regimen exactly though. |
Thanks
Dan,
Thanks for the input. Sorry I haven't replied earlier. We have been busy with Hurricane Irma down here in Florida. Think she is gone now. Good riddance to her and my two ex-wives. Ha Ha. Datd |

Very glad to hear that you weathered the storm successfully. Hopefully not too much damage to go back to. |
Thanks Dan
Dan,
We never evacuated. I said I would evacuate when it got to a Category 6 (Ha Ha). We only had really small tree limbs break. We lost power for about 8 hours. No Flooding. The refrigerator kept everything cold/frozen. We were very lucky! I feel for those less fortunate. Thanks again Data |
