Using Frozen Section to Identify Histologic Patterns in Stage I Lung Adenocarcinoma ≤3 cm: Accuracy and Interobserver Agreement

摘要

AimsThe IASLC/ATS/ERS classification of lung adenocarcinoma provides a prognostically significant histologic subclassification. The aim of this study is to investigate the accuracy, limitations, and interobserver agreement of frozen sections (FS) for predicting histologic subtype.
