A new tumor marker TAG-72 and its value in diagnosis of gastric carcinoma[J]. Journal of Chongqing Medical University, 1998,(4):349-351. DOI: 10.13406/j.cnki.cyxb.1998.04.034.
This article evaluated the serum levels of a new tumor marker TAG-72 in diagnosis of gastric cancinoma. Serum tumor marker CA72-4 were measured in 30 patients with gastric carcinomas and 10 with benign gastric disorders.CA72-4 had sensitivities of 43% and specifcity of 100% for gastric carcinomas.CA72-4 can significantly separate stage Ⅰ disease from stage Ⅱ Ⅲ Ⅳ disease(P<0.05)CA72-4 also gave differentiation bwtween patients with positive and negative nodes(P<0.05).These preliminary findings indicate that TAG-72 is a reliable tumor marker of disease stage and activity in gastric cancer.Further longitudinal studies are repuired for full evaluation of its clinical utility.
