Radiation before pills may slow lung cancer progression

This study tests whether giving radiation to the main lung tumor before starting targeted therapy pills can delay cancer growth in people with advanced, gene-mutated non-small cell lung cancer. About 34 adults who have not yet had treatment will receive radiation to the primary lung lesion, then take a tyrosine kinase inhibitor (TKI). The goal is to see if this combination keeps the cancer from progressing longer than TKI alone.
