Procedures
All patients underwent pretreatment evaluations, including a complete medical history and physical examination; complete blood count and chemistry profile of the serum; urine test; test of pulmonary function; electrocardiogram; examination of the barium swallow; neck, chest, and upper abdomen computed tomography (CT) scan with contrast; and ultrasonography by endoscopy. The patient underwent bronchoscopy if the diagnosis of bronchial invasion was suspected. Radionuclide bone scans and co-registered 18 F-labeled fluoro-2-deoxy-D-glucose positron emission tomography (PET/CT) scans were also performed when clinically indicated.The treatment plan is illustrated in Fig.
