Hi Monica,
i was diagnosed stage 4 adenocarcinoma about five weeks ago. Initially it was thought to be stage 1, but during surgery it was discovered that there was spread to the pleura and so I am now stage 4 as well. I am waiting for genetic testing in my cancer to come back so I can pick the treatment approach. If I have the applicable mutation, I am leaning towards targeted therapy. But, like you, I am also considering a clinical trial involving the two immunotherapy drugs you mentioned. Not sure what to do myself, but if targeted therapy is not a match for me, I am thinking of trying the combo of immune therapies. If you get any good info, please let me know and I will do the same for you if I hear of something.
All the best to you. Let's fight this thing.
Martin
