When comparing the nomogram score in pancreatic cancer patients (n = 57) with the CA19-9 and CEA levels, the nomogram presented slightly higher performance than CA19-9 (AUCnomogram = 0.71 vs AUCCA19-9 level = 0.70, p = 0.88) and lower performance than CEA (AUCnomogram = 0.71 vs AUCCEA level = 0.73, p = 0.83); however in both comparisons the differences did not reach statistical significance. The gene discussed is CEACAM5; the disease is familial pancreatic carcinoma.
