Fourteen preoperative clinical and pathological variables were used to develop a probability model, in which their association with 3-year survival was tested. A nomogram to predict median, 1- and 3-year survival was constructed and validated internally using the concordance index (c-index).

The nomogram was well calibrated for predicting 3-year overall survival. The internal validated c-index of the nomogram was 0\u00b772.
