本文报告69例胃液中 IgG、IgA 的测定及其在胃癌诊断中的意义。胃癌组36例,IgG 阳性26例(72.7%),IgA 阳性27例(75%);胃良性疾患组21例,19例 IgG、IgA 均为阴性(90.48%);正常对照9例,除1例 IgA阳性外,余均为阴性;胃外肿瘤组3例,其 IgG、IgA 均为阴性。因此,胃液中IgG、IgA 测定在胃癌诊断中具有特异性。 This article reports the determination of IgG and IgA in gastric fluid in 69 cases and its significance in the diagnosis of gastric cancer. Among 36 patients with gastric cancer, 26 were IgG positive (72.7%) and 27 were positive for IgA (75%); 21 were positive for benign gastritis; 19 were IgG and IgA were negative (90.48%); 9 normal controls, except 1 In cases with positive IgA, all were negative; in the extragastric tumor group, 3 cases were negative for IgG and IgA.
