Stage IIIB NSCLC management consists of which of the following?

• A. Chemotherapy/immunotherapy + radiation
• B. Surgery
• C. Radiation alone
• D. Observation

Answer: (A)

Locally advanced, unresectable stage IIIB NSCLC is best treated with a multimodal approach that combines systemic therapy with thoracic radiation. The tumor is often too invasive or nodal-disease–heavy for safe surgical removal, and radiation alone cannot control micrometastatic disease. Chemotherapy helps address systemic disease and also sensitizes tumor cells to radiation, while concurrent thoracic radiotherapy provides strong local control. This combination improves survival and disease control more than either modality alone. In modern practice, immunotherapy is commonly added after completing chemoradiation as maintenance therapy, further enhancing outcomes. Therefore, the management centers on delivering chemotherapy (often with immunotherapy in current protocols) together with radiation.
