Comparison of Tumor markers, alpha feto protein and carcinoembryonic antigen [C.E.A] with Alkaline phosphatase in patients with gastrointestinal tumors

Seven CEA, alpha-fetoprotein and alkaline phosphatase have been assayed in 32 patients with gastrointestinal cancers. CEA proved to be the valuable marker in determining the prognosis of colon, stomach and pancreatic cancers. In each case, alkaline phosphatase and alpha- fetoprotein were non diagnostic of 25 colon cancer patients, 12 had surgical treatment, CEA showed a fall to normal values in 10 cases [8 had radiotherapy]
