Proton Beam Radiation Therapy in Patients With Resected N2 Non-Small Cell Lung Cancer
Emory University
Summary
This clinical trial tests proton beam radiation therapy in patients with non-small cell lung cancer who have undergone surgical resection and have lymph nodes involving the middle of the chest. Proton therapy is a type of radiation treatment that kills cancer cells while avoiding surrounding healthy tissue. Proton beam therapy is sometimes used after cancer surgery to reduce the risk of cancer recurrence (coming back). Giving proton beam radiation therapy may work better than conventional radiation treatment after surgery in patients with non-small cell lung cancer.
Description
PRIMARY OBJECTIVE: I. To assess the safety of proton beam radiation therapy (PBRT) for resected N2 non-small cell lung cancer (NSCLC). SECONDARY OBJECTIVES: I. To measure the radiation dose to the circulating immune compartment and explore its association with clinical endpoints. II. To assess the efficacy of PBRT for resected N2 NSCLC. OUTLINE: Patients undergo radiation treatment planning and then undergo proton beam radiation therapy on study. Patients also undergo collection of blood samples. Patients are followed up for 24 months after first dose of radiotherapy.

Inclusion Criteria: * Age \>= 18 years * Patients must have undergone complete surgical resection after pre-operative systemic therapy. Complete resections are defined as BOTH lobectomy, sleeve lobectomy, bilobectomy, or pneumonectomy AND lymph node dissection with at least three mediastinal (N2) stations sampled * Pathology report from surgical resection indicating complete resection of primary tumor (R0 resection) AND tumor involvement of at least one mediastinal lymph node (pN2) AND no tumor involvement of highest dissected mediastinal lymph node.
