So sorry to hear about your NSCLC!
I am a caregiver for my wife, who was diagnosed with Adenocarcinoma, stage 3a NSCLC in May, 2015. Her cancer had not metastasized at that time so Mayo removed 2 lower lobes of her right lung. After going thru chemo therapy, her scan the following year showed the tumors had grown and our Mayo oncologist re-staged her to stage 4 inoperable NSCLC.
He put her on Opdivo, but after 4 months of the therapy, the scans showed that she was not responding. The Mayo oncologist then ordered a lung biopsy, which was sent to Foundation One in Boston for a molecular study.
The study showed her mutation, although in her lungs was indeed a HER2 mutation, normally found in breast cancer patients. Our Mayo oncologist then put her on infusions of a trial doublet of herceptin and PERJETA.
My wife is still responding well to the infusions every 3 weeks. The last PET CT scan showed the tumors have stablized, for which we are extremely grateful. We are convinced that the Mayo oncologist who ordered the Trial is our guardian angel!
Although yours is a squamous cell (different that Adenocarcinoma), I would suggest you to talk with you oncologist about the possibility of having a molecular study done...best of luck...God bless!
