Within 6 weeks after the last treatment, the patient's tumor will be evaluated with a blood test and CT scan of the chest, abdomen and pelvis to determine if it can be removed with surgery. If so, the procedure will be done under general anesthesia and will require a 7- to 10-day hospital stay. If the tumor cannot be removed with surgery, another biopsy will be taken to evaluate the tumor's response to the chemotherapy and radiation treatment.
