Hello poodledoc,
The results of genetic marker testing of lung cancer tumors really need to be reviewed and interpreted by an oncologist. Those test results can be quite technical and hard for a lay person to interpret. From my somewhat limited knowledge, Tagrisso is only prescribed and beneficial when the tumor is EGFR positive. Again, depending on the full panel of genetic marker testing conducted on the tumor tissue, an oncologist can outline their recommended course of treatment. It does help to educate yourself as much as possible on the subject beforehand so that you can get all your questions answered and to make decisions that you are comfortable with. Chemotherapy treatments can be quite beneficial however it helps to understand the potential “cure” rates and reported likely side effects.

Good luck!
