Prognostic performance of three lymph node staging schemes for patients with Siewert type II adenocarcinoma of esophagogastric junction.

ABSTRACT: The prognostic performance of different lymph node staging schemes for adenocarcinoma of esophagogastric junction (AEG) remains controversial. The objective of the present study was to compare the prognostic efficacy of the number of lymph node metastases (LNMs), the positive lymph node ratio (LNR) and the log odds of positive lymph nodes (LODDS). Patients diagnosed with Siewert type II AEG were included from the Surveillance, Epidemiology, and End Results database. Harrell's C-index statistic, Schemper's proportion of explained variation (PEV), the Akaike information criterion (AIC) and restricted cubic spine analyses were adopted to assess the predictive accuracy of LNM, LNR and LODDS. A total of 1302 patients with post-surgery Siewert type II AEG were included. LNM, LNR and LODDS all sh
