Imaging and Laboratory Evaluation
Imaging studies included two-view chest x-ray, contrast enhanced neck, chest, abdominal and pelvic computed tomography (CT). Patients who could not have a CT scan (they were too ill, or CT was not available) had an evaluation with an ultrasound of the neck, axilla, abdomen, pelvis and inguinal regions. There was a response assessment at the end of 12-week chemotherapy and after completion of radiation therapy.
