How important is it to get markers for a person who was a smoker ?
The first biopsy yielded only enough viable tissue to diagnose adenocarcinoma ... and no marker info.
The drs. seem to think it's no big deal to proceed with chemo in the future having no markers info., since he was smoker, so little chance he would be positive for EGFR, ALK, ROS or PD-L1 so they would just proceed as if he doesn't have any of these.
That thinking shocks me, so wondering this site's opinion.
