In the differential diagnosis of pancreatic carcinoma from benign pancreatic diseases, CA 19-9 can be useful in the nonjaundiced patients, whereas CA 125 provides a limited contribution in jaundiced patients.

Although the incidence of PNI is high in gastric carcinoma and increases with the progression of disease, it does not provide any additional information to the classical prognostic parameters.

In resectable gastric carcinoma, preoperative serum CA 19-9 and CEA levels may indicate stage of the disease, but neither has an independent prognostic value.
