A 67 year old male with a 2.9 cm lung nodule undergoes EBUS; Stage should be considered?

Explanation:
Stage is determined by the TNM system: tumor size and extent (T), nodal involvement (N), and distant metastasis (M). A 2.9 cm lung nodule is classified as T1b. If EBUS shows cancer in mediastinal lymph nodes, that’s N2. With no distant metastasis (M0), this combination places the cancer in stage IIIA. If the nodal disease were N3, it would be stage IIIB, and if metastasis were present, it would be stage IV. EBUS helps determine nodal status, so finding N2 disease after an EBUS assessment leads to stage IIIA.
