Hi Mary Ann, do you have any follow up scheduled with a medical oncologist? Adenocarcinoma is a type of non small cell lung cancer, but there are many different kinds and it is hard to know how to prognosticate without knowing exactly what kind your sister has. A medical oncologist will be able to answer your questions about the extent of disease in her body better than your neurosurgeon. Do you know what the plan for treatment is of her cerebellar tumors? Sometimes, depending on the size of the tumor, your sister may be a candidate for additional surgical resection. Other times, Gamma Knife/or radiosurgery is recommended. I wish you and your sister the best of luck and hope this was helpful.
