Does Positron Emission Tomography Prevent Nontherapeutic Pulmonary Resections for Clinical Stage IA Lung Cancer?
Background: The American College of Surgeons Oncology Group (ACOSOG) Z0050 trial demonstrated that positron emission tomography (PET) prevents nontherapeutic thoracotomies in a substantial fraction of patients with known or suspected non-small cell lung cancer (NSCLC). However, the benefit of PET in clinical stage IA patients has been questioned due to the lower prevalence of metastases and poor ability to discriminate benign from malignant lung lesions. This study evaluates whether PET prevents nontherapeutic pulmonary resections in clinical stage IA patients by finding advanced disease or by declaring a nodule as benign.
