Testing Repeat Radiation Therapy for Recurrent Non-small Cell Lung Cancer
This phase II trial compares repeat radiation therapy (RT) to standard drug treatment alone in treating patients with stage II-III non-small cell lung cancer (NSCLC) that has come back after initial radiation at or adjacent to the site of the original tumor (locally recurrent). Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Chemotherapy drugs used in standard drug treatment work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy drugs used in standard drug treatment may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Targeted therapy drugs used in standard treatment identify and attack specific tumor cells. This trial may help doctors determine whether repeat RT delays the cancer from growing or spreading by 6 months or more after initial radiation compared to standard drug treatment alone in patients with stage II-III locally recurrent NSCLC.
