Study aims to determine if functional lung avoidance based on perfusion single photon emission (SPECT)/CT scan, improves toxicity outcomes for patients with advanced lung cancer undergoing chemo-radiotherapy. Functional avoidance implies a dose plan that takes functional distribution in the lung into account, and avoids highly functional lung volumes sparing them from radiation.
histologically verified lung cancer (small-cell and non-small cell lung cancer)
referred for radiotherapy with curative intent
radiation dose of 60-66 Gy given in 2-Gy fractions, other dose levels and fractionation schedules accepted, as per site standard
concurrent chemotherapy is accepted
concurrent immunotherapy
previous radiotherapy to the thorax
other uncontrolled malignancies; any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol
Parallel
Single-photon-emission CT scan
Diagnostic testSPECT/CT scan is an established functional modality used in the diagnosis and monitoring of lung disease. SPECT/CT scan images pulmonary circulation, where perfused areas equate with normal functional lung
Radiation-induced lung toxicity
crude rate of symptomatic radiation-induced lung toxicity of grade 2 and higher. According to the Common Toxicity Criteria for Adverse Events version 5.0 for radiation pneumonitis, dyspnea, cough, or any other radiation-induced respiratory, thoracic and mediastinal disorder.
Quality of life
Change in quality of life according to the European Organisation for Research and Treatment of Cancer quality of life questionnaires

Progression-free survival
time from randomization to disease progression at any site or death
Overall survival
time from randomization to death of any cause or last date known alive
