Lung Cancer Clinical Trials

The number of long-term lung cancer (LC) survivors increases, however many patients are diagnosed with recurrent or new thoracic cancers. High-dose reirradiation (reRT) is promising but associated with high severe toxicity rates. Existing studies are small lacking high-quality data, with no clear correlation between toxicity risk and delivered radiotherapy (RT) dose. This Danish multicentre prospective cohort study aims to provide a framework for collecting radiotherapy-related toxicity data, loco-regional control, and overall survival data for patients with thoracic cancer undergoing reirradiation; with the ultimate aim of providing safe reirradiation to more patients. As a secondary aim, guidelines for dose accumulation and provisional constraints for the organs at risk will be used to establish a uniform treatment strategy for reirradiation. The CURE Lung trial will provide high-impact, globally missing data. This project will ensure full utilization of and learning from the trial, adding SDM, PROMs, and modality referral to the trial. It will model the correlation between toxicity burden and doses, enabling individualized reRT with optimized dose prescription based on toxicity risk and patient preferences, and assisting in the decision-making on the prescription dose and optimal modality. This will ensure safe reRT for the increasing number of long-term LC survivors.
