Tarceva

Does anyone know how long a patient can take Tarceva? It appears that our tumors become resistent to drugs after a while, so I'm curious to know how long this one might work.
Also, has anyone had any experience with C-Statin for NSCLC?
Finally, we are the orphans of the cancer club my friends. With research underfunded and far too many fatalities we need to speak out before we die so the rest of the world carries on our fight. Please make your voice heard in your community this November....even if that voice is a little hoarse and out of breath. We owe it to future generations to do what we can while we are still here.
