Abstract

Treatment of locally recurrent non-small lung cancer (NSCLC) after definitive chemoradiation therapy is challenging as patients are often inoperable and systemic therapy alone frequently results in suboptimal outcomes. Re-irradiation of NSCLC may be the best strategy for treating locoregional failures with the goal of durable long-term control and potentially cure. Repeat irradiation is technically challenging for fear of life-threatening toxicities to previously irradiated organs at risk while also delivering definitive doses of radiation to recurrent disease. No standard guidelines exist with regards to re-irradiation technique and re-treatment dose constraints to organs at risks. We herein describe a case of locoregional recurrence after definitive chemoradiation therapy for NSCLC with expert opinions for subsequent management. As described and guided by our experts, we review the various techniques for repeat radiation therapy, treatment planning goals, and reported toxicities and outcomes in the re-irradiation setting.
