My dad has been diagnosed with NSCLC adenocarcinoma that is EGFR 19 deletion and ALK positive. I understand that this is an extremely rare case to have 2 mutations and I am wondering if this were the case, whether we should be treating for these 2 mutations concurrently? He is currently taking Iressa and our onco has suggested to continue with Iressa for the time being.
I am feeling a little concern about not treating for ALK as well, in fear that just taking Iressa would only treat the EGFR mutation which may then allow the ALK to continue to progress.
Could you please advice as to what we should be doing?
