Advances in the accuracy of the frozen section (FS) identification for early-stage lung adenocarcinoma

Abstract

The frozen section (FS) technology has been widely used in the process of surgical pathology since its time-saving nature exhibited superiority over traditional paraffin method. Therefore FS, of great value in providing preliminary pathological diagnosis, offers guidance in the extension of surgical resection. However, it remains controversial whether the early-stage lung adenocarcinoma could be accurately identified in FS. This review aims to generalize the studies concerning the accuracy of FS in identifying early-stage lung adenocarcinoma, analyzing the interference factors, comparing the similarities and differences between frozen sections and traditional paraffin sections. It also gives insight into whether FS can provide significant guidance for surgeons to perform resection on early-stage lung adenocarcinoma.
