Abstract
BACKGROUND: In clinical Ia (cT1N0M0) patients, some may have poor prognosis, for it might occur pathologic N1 (pN1) or N2 (pN2) postoperatively. The aim of this study is to determine the radiologicaland pathological factors related to clinical Ia adenocarcinoma.Entities:

1不同N分期总体生存时间
Overall survival curves of patients according to N status.In nodal upstaged patients, 3-year OS of 80.85% (mean OS of 42 months; 95%CI:37-47), while in non-upstaged group, 3-year OS of 99.60% (mean OS of 62 months; 95%CI:60-65) (P < 0.000, 1).OS:overall survival.
