TYMS and non-small cell lung carcinoma: Five variables, including the TS status (hazard ratio 2.663; P=0.0003), OPRT status (hazard ratio 2.534; P=0.0005), DPD status (hazard ratio 2.840; P<0.0001), pathological stage (hazard ratio 1.908; P<0.0001), and the methods of surgical resection (a pneumonectomy vs other methods)(hazard ratio 2.555; P=0.0242), were demonstrated to be significant prognostic factors for survival of resected NSCLC patients postoperatively treated with UFT.
