Core Tip

Core Tip: Lymph node (LN) counts of gastric remnant cancer (GRC) patients are often insufficient, and the prognostic ability of traditional LN stage (N stage) is therefore limited. This study investigated the predictive value of LN ratio (LNR) according to clinicopathological characteristics and prognosis of patients with locally advanced GRC. Compared with N stage, the new LNR stage had significant prognostic value for patients with locally advanced GRC, and it could better differentiate overall survival in patients, compared with N stage.
