Table 2.

Publications on nodule category of PSN < 80%, listed by the different groups reported in each study. For each group, the number of patients, follow-up time, lymph node metastases, disease-free survival (DFS), overall survival (OS), and R1 (ratio of solid component to the overall nodule size) is given

NSN = Nonsolid nodule, defined as R1 = 0% or GGO =100%; PSN = part-solid nodule, defined as R1 = 1-79%; SN = solid nodule, defined as R1 = 100% (alternatively R2 = 0%), and PSN≥80%

Study did not report on survival rate, rates estimated from figure.

^†

Numbers based on length method reported in the study. Mean 5-year relapse-free survival and mean number of patients having a GGO extent of 50% or more among seven institutions

DFS: 96.4% lobectomy (n = 90), 96.1% segmentectomy (n = 56), 98.7% wedge (n = 93); OS: 97.6% lobectomy, 98.2% segmentectomy, 98.7% wedge. For calculation of median survival rates, the lowest DFS and OS among the different types of surgery were used to provide conservative estimates
