TAnn Posted January 6, 2005 Share Posted January 6, 2005 I saw the doctor yesterday to get the results of the brain MRI. The tumors are stable and some "appear to be slightly smaller" according to the report. Keeping in mind that mine are very small to begin with, I don't read alot into that. So basically the news is stable. I can live with stable.... We also discussed Tarceva. He went into the big explanation of the Iressa news, not knowing that we were armed with info, thanks to everyone here, and we were finishing his sentences before he could ... Anyway, we decided to switch to Tarceva. I am on 150mg. and am really scared about the side effects. Here is what he said about what he and the other doctors at MD Anderson are doing about Iressa: If a patient has received substantial benefit from Iressa, meaning substantial tumor shrinkage and stabilization of disease, then Iressa has benefitted them and they should stay with Iressa. If a patient has received minimum benefit from Iressa, meaning very little, if any, tumor shrinkage but has remained stable it would be beneficial to switch to Tarceva as it has "proven" extended survival rate. Therefore, we agreed and made the switch. He said that Iressa and Tarceva are exactly the same drug, they target the tumor in exactly the same way. The only difference is that Iressa is formulated in different dosages than Tarceva. ie: Iressa's 250mg dosage is lower than Tarceva's 150mg dosage. The medication dosage is stronger in Tarceva and therefore the benefit is better. If I have bad side effects, he will switch me to the 100mg dose. After reading the Tarceva website, I see that it is available all the way up to 1000mg. Can you imagine????? Thank you all for your thoughts and prayers. I will keep you updated on my side effects.
