Note 1: Direct extension to or other involvement of structures considered M1 in AJCC staging is coded in the data item CS Mets at DX. This includes: sternum; skeletal muscle; skin of chest; contralateral lung or mainstem bronchus; separate tumor nodule(s) in different lobe, same lung, or in contralateral lung.
Note 2: Distance from Carina. Assume tumor is greater than or equal to 2 cm from carina if lobectomy, segmental resection, or wedge resection is done.
Note 3: Opposite Lung. If no mention is made of the opposite lung on a chest x-ray, assume it is not involved.
Note 4: Bronchopneumonia. "Bronchopneumonia" is not the same thing as "obstructive pneumonitis" and should not be coded as such.
Note 5: Pulmonary Artery/Vein. An involved pulmonary artery/vein in the mediastinum is coded to 70 (involvement of major blood vessel). However, if the involvement of the artery/vein appears to be only within lung tissue and not in the mediastinum, it would not be coded to 70.
Note 6: Pleural Effusion.
Note 7: Vocal cord paralysis (resulting from involvement of recurrent branch of the vagus nerve), superior vena cava obstruction, or compression of the trachea or the esophagus may be related to direct extension of the primary tumor or to lymph node involvement. The treatment options and prognosis associated with these manifestations of disease extent fall within the T4-Stage IIIB category; therefore, generally use code 70 for these manifestations. HOWEVER, if the primary tumor is peripheral and clearly unrelated to vocal cord paralysis, vena cava obstruction, or compression of the trachea or the esophagus, code these manifestations as mediastinal lymph node involvement (code 20) in CS Lymph Nodes unless there is a statement of involvement by direct extension from the primary tumor.
