The authors analysed 27 patients. It is shown that the X-ray and endoscopic methods possess sufficiently high sensitivity in identifying elevated forms of early carcinoma of the stomach (in 90% and 100%, respectively). Their specificity, however, is low because errors of each method come up to about 50%. The results of cytohistological examination are decisive in establishing the correct diagnosis. Biopsy of all elevated structures is necessary. Bearing in mind the possibility of false-negative results, the authors recommend to conduct it three times.
作者分析了27例患者。结果表明，X射线和内镜检查方法在识别早期胃癌隆起型方面具有足够高的灵敏度（分别为90%和100%）。然而，它们的特异性较低，因为每种方法的误差高达约50%。细胞组织学检查结果对确立正确诊断起决定性作用。对所有隆起结构进行活检是必要的。考虑到可能出现假阴性结果，作者建议进行三次活检。
