胃癌为我国常见的恶性肿瘤,发病率较高,占男性恶性肿瘤的第1—2位。但早期不易发现,大多数病例就诊时已属晚期。因此,寻找一种简易的无创伤性的早期诊断方法。已成为目前急待解决的课题。 Deutsch等人在1973年从胃癌病人胃液中发现一种肿瘤相关抗原GCAA(Gastric cancer Associated antigen)它与经吸收过正常胃液、正常血清的相应抗血清作免疫电泳,在
Gastric cancer is a common malignancy in China, with a high incidence rate and accounting for the 1st to 2nd positions of male malignant tumors. However, it was not easy to find in the early stages, and most of the cases were advanced at the time of treatment. Therefore, look for a simple non-invasive early diagnosis method. Has become an urgent issue to be solved. In 1973, Deutsch et al. discovered a gastric-associated antigen GCAA (Gastric cancer Associated antigen) from the gastric juices of gastric cancer patients. It was used to perform immunoelectrophoresis with corresponding antiserum collected from normal gastric fluid and normal serum.
