A statistical model for predicting disease-specific survival in patients with gastric carcinoma, based on a single U.S. institution experience, was tested for validity in a sample of patients treated at different institutions.


The authors analysed 459 patients from the Dutch Gastric Cancer trial that compared limited (D1) with extended (D2) lymph node dissection. The discrimination ability of the nomogram with respect to 5 and 9-year disease-specific survival probabilities was superior to that of the American Joint Committee on Cancer (AJCC) staging system.


There was considerable heterogeneity of risk within many of the AJCC stages. Calibration plots suggested that predicted probabilities from the nomogram corresponded closely to actual disease-specific survival. The gastric carcinoma nomogram performed well when applied to patients treated in a large number of institutions.


The nomogram provided predictions that discriminated better than the AJCC staging system, regardless of the extent of lymph node dissection. Patient counseling and adjuvant therapy decision-making should benefit from use of the nomogram.
