Abstract
PURPOSE: To provide guidance to physicians and patients with regard to the use of definitive external beam radiation therapy (RT) in locally advanced non-small cell lung cancer (LA NSCLC) based on available medical evidence complemented by consensus-based expert opinion. METHODS AND MATERIALS: A panel authorized by the American Society for Radiation Oncology (ASTRO) Board of Directors and Guidelines Subcommittee conducted 3 systematic reviews on the following topics: (1) ideal radical RT dose fractionation for RT alone; (2) ideal radical RT dose fractionation for chemoradiation; and (3) ideal timing of radical radiation therapy with systemic chemotherapy. Practice guideline recommendations were approved using an a priori-defined consensus-building methodology supported by ASTRO and approved tools for the grading of evidence quality and the strength of guideline recommendations. RESULTS: For patients managed by RT alone, a minimum dose of 60 Gy of RT is recommended. Dose escalation beyond 60 Gy in the context of combined modality concurrent chemoradiation has not been found to be associated with any clinical benefits. In the context of combined modality therapy, chemotherapy and radiation should ideally be given concurrently to maximize survival, local control, and disease response rate. CONCLUSIONS: A consensus and evidence-based clinical practice guideline for the definitive radiotherapeutic management of LA NSCLC has been created that addresses 3 important questions.
