TX

If the primary tumor cannot be assessed, a TX classification is assigned. The presence of lung cancer cells in sputum with no evidence of tumor by bronchoscopy or on imaging (occult carcinoma) is classified TX. A bronchioalveolar carcinoma that presents as an infiltrate, with no evidence of tumor or obstruction on imaging or at bronchoscopy may be designated TX.
