PurposeWe比较了三维（3D）和二维（2D）测量的实体成分，以确定放射学标准肺叶切除肺腺癌≤ 2cm的大小。结果原位腺癌（n= 43）和微创腺癌（n= 77）的预测性能相当于2D和3D测量的曲线下面积为0.871和0.857（p =0.229）。5 mm的固体成分对两个测量值均有预后影响（≤ 5 mm vs> 5 mm; 2D p =0.003，3D p =0.002，对数秩检验）。对于固体成分≤ 5 mm的患者，行肺叶切除术和肺叶下切除术后的5年生存率为94.7-96.9%。肺叶切除术导致更差的生存率，在5年的下降15.8%的2D和11.5%的3D测量，比肺叶切除术的患者与一个坚实的组成部分> 5 mm的size.ConclusionsA坚实的组成部分≤ 5 mm的大小是一个适当的标准为肺叶切除术的两个测量。此外，2D测量是合理的，因为其简单的实施。
PurposeWe compared three-dimensional (3D) and two-dimensional (2D) measurements of the solid component to determine radiological criteria for sublobar resection of lung adenocarcinoma ≤ 2 cm in size.MethodsWe included 233 surgical cases. The maximum size of the solid component for 3D measurement was calculated by delineating the solid component on successive axial images and reconstructing the 3D surface model.ResultsThe predictive performance for adenocarcinoma in situ (n= 43) and minimally invasive adenocarcinoma (n= 77) were equivalent to areas under the curve of 0.871 and 0.857 for 2D and 3D measurements (p =0.229), respectively. A solid component of 5 mm had a prognostic impact on both measurements ( ≤ 5 mm versus > 5 mm;p =0.003 for 2D andp =0.002 for 3D, log-rank test). Survival rates at 5 years were 94.7–96.9% following lobectomy and sublobar resection among patients with a solid component ≤ 5 mm in size. Sublobar resection resulted in worse survival rates, with declines at 5 years of 15.8% on 2D and 11.5% on 3D measurements, than lobectomy in patients with a solid component > 5 mm in size.ConclusionsA solid component ≤ 5 mm in size is an appropriate criterion for sublobar resection for both measurements. In addition, 2D measurement is justified because of its simple implementation.
