How this model should be used:
This model predicts 5-year overall survival after gastric resection with D2 lymphadenectomy (D2 gastrectomy) for gastric cancer. It can be applied for improved individualized predictions of survival.
Model performance:
In the Seoul National University Hospital (SNUH) validation set (N=2,654), the nomogram exhibited superior discrimination power compared with the seventh American Joint Committee on Cancer TNM classification (c-index, 0.78 v 0.69, respectively; P < 0.001). Calibration of the nomogram predicted survival corresponding closely with the actual survival (Figure 1). In the Cancer Institute Ariake Hospital (CIAH) validation set (N=2,500), the reported c-index was 0.79. In addition, the predicted survival was within a 10% margin of actual survival (Figure 2).
