My sister returned to hospital on Tuesday with severe chest pain . They were afraid of pulmonary embolism but CT scan didn't show that. Instead elevated inflammatory markers and symptoms made Drs diagnose inflammation of pericardium. She has fluid in right lung and some in left. She is no longer in pain but liver enzymes are elevated perhaps because of all medication given to her on Tuesday. Written biopsy report will be given to us on Monday but surgeon told us orally that there is some lymph node involvement which scares us. Mitotic rate is about 2 (1.9 to be exact), there is some necrosis and stuff about lymph node #7 ( I also heard sth about because it involves node 7 it is classified ad N2. Don't understand any of this. Don't know KI 67 yet but they assume it's about 6-7℅. I'm tired of listening to them say not to worry and that everything will be ok, especially when I read online how aggressive this carcinoid is and when there is node involvement and necrosis prognosis is poor. Treatment is also not helpful from what I've read. Please give me any feedback.
