I had the same diagnosis: stage IV NSCLC adenocarcinoma in both lungs. At that time systemic treatment by infusion was my only option. I only had KRAS mutation and they didn’t test for PD-L1 then. So it’s still possible that you would be eligible for a targeted therapy or Keytruda right up front. Things will calm down when you know that and have a treatment plan in place. You will not find anyone who has ever said the waiting wasn’t one of the hardest parts. Try to enjoy the rest of the holiday weekend knowing that you’ll know more on Monday.
