Journal Article
Patient Selection of Sublobar Resection Using Visual Evaluation of Positron-Emission Tomography (PET) for Early-Stage Lung Adenocarcinoma
2021
Overview
BackgroundThis study aimed to investigate the efficacy of the Deauville criteria (a 5-point visual scale criteria) in assessing the accumulation of [18F]-fluoro-2-deoxy-d-glucose (FDG) on positron-emission tomography (PET)/computed tomography (CT) for predicting prognosis of early-stage lung adenocarcinoma and selecting candidates for sublobar resection.MethodsThis retrospective study included 648 patients undergoing curative resection for clinical N0 lung adenocarcinoma with a whole tumor size of 3 cm or smaller between April 2007 and March 2019. Accumulations of the FDG on PET/CT scans were scored using the Deauville criteria (Deauville score), and correlations between the Deauville score and prognosis were analyzed.ResultsThe recurrence-free survival (RFS) was significantly better for the patients with a Deauville score of 1 or 2 (n = 415, 5-year RFS, 92.6%) than for those with a score of 3 (n = 82, 5-year RFS, 72.7%; P < 0.001) or a score of 4 or 5 (n = 151, RFS, 70.8%; P < 0.001). The RFS did not differ significantly among the patients with Deauville scores of 1 and 2 who underwent wedge resection (n = 102, 5-year RFS, 90.5%), segmentectomy (n = 188, RFS, 95.1%; P = 0.355), and lobectomy (n = 125, RFS, 91.1%; P = 0.462).ConclusionThe 5-point-scale evaluation of FDG accumulation on PET/CT was useful in predicting the prognosis for patients with early-stage lung adenocarcinoma. Lung adenocarcinoma patients with a whole tumor size of 3 cm or smaller and a Deauville score of 1 or 2 can be candidates for sublobar resection.
