Clinical Features of Patients According to Pulmonary Function During Follow-up.

All patients with decreased lung function demonstrated either a severe restrictive pattern (four patients) or a severe obstructive pattern (one patient).†%, % in FVC, FEV1, and DLCO denote percentage of measured to predicted values.*Baseline DLCO was measured in 13 patients with stable pulmonary function and 4 patients with decreased pulmonary function. DLCO was measured during follow-up in 20 patients in the stable PFT group and 4 patients in the impaired PFT group.**Tumor and lymph node staging according to the TNM staging system (American Joint Committee on Cancer, Seventh Edition, 2010).RAIT, radioactive iodine treatment; IQR, inter-quartile range; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; DLCO, Carbon monoxide diffusing capacity; CT, computed tomography; WBS, whole body scan.Clinical Features of Patients According to Pulmonary Function During Follow-up.
