Subsolid pulmonary nodules: CT–pathologic correlation using the 2011 IASLC/ATS/ERS classification

Hilly or mountainous surface: a new CT feature to predict the behavior of pure ground glass nodules?

“…Persistent SSNs have a high likelihood to represent pre-invasive or invasive adenocarcinomas, particularly part-solid nodules [ [3] , [4] , [5] ]. As a result, the updated Fleischner Society guidelines for the management of SSNs, published at the beginning of 2017, recommend a follow-up period for every pGGN or part-solid nodules ≥ 6 mm in diameter [ 1 ].…”

Nomogram for Predicting the Risk of Invasive Pulmonary Adenocarcinoma for Pure Ground-Glass Nodules

“…Although the etiology of a pGGN is varied, lung adenocarcinoma is the most common histologic type [3]. Preinvasive lesions have a 100% 5-year disease-free survival [4,5].…”

Prognostic significance of histologic classification and tumor disappearance rate by computed tomography in lung cancer

“…However, since accurate subtype can be known after surgery, radiologic parameters have been attempted to replace pathologic results (17)(18)(19)(20)(21)(22)(23)(24)(25). Takahashi et al demonstrated that GGO ratio, TDR, and consolidation diameter were strong indicators of tumor invasiveness according to the new classification system (22).…”

“…To help surgeons decide the extent of pulmonary resection preoperatively, some researchers have attempted to predict pathologic invasiveness based on various radiologic parameters including the GGO ratio and the tumor disappearance rate (TDR) (17)(18)(19)(20). Although several studies have investigated the relationship between radiologic parameters and pathologic features of lung adenocarcinoma based on the new IASLC/ATS/ERS classification system (21)(22)(23)(24)(25) few reports have focused on adenocarcinoma with GGO feature.…”
