Development of a novel staging classification for Siewert II adenocarcinoma of the esophagogastric junction after neoadjuvant chemotherapy

Figure 1 Flow chart.

Figure 2 Online web nomograms for predicting 1-, 3-, and 5-year. A: Overall survival for Siewert type II adenocarcinoma of the esophagogastric junction (AEG) underwent radical gastrectomy with neoadjuvant chemotherapy; B: Disease-specific survival for Siewert type II AEG underwent radical gastrectomy with neoadjuvant chemotherapy. OS: Overall survival; DSS: Disease-specific survival; ACT: Adjuvant chemotherapy.

Figure 3 Comparison of nomogram properties. A and B: Calibration of the nomogram for 5-year overall survival (OS) and disease-specific survival (DSS); C and D: Time- receiver operating characteristic curves of the nomogram for 5-year OS and DSS; E and F: Decision curves of the nomogram for 5-year OS and DSS. EC: Esophageal cancer; GC: Gastric cancer; ypTNM: Y-pathologic-TNM.
