胃癌诊断的研究进展

Progress in Diagnosis of Gastric Cancer

胃癌是最常见的恶性肿瘤之一,因早期胃癌缺乏特异性临床表现,难以与胃良性疾病相鉴别,致使早期胃癌漏诊率及误诊率均较高,发现时多已属中晚、期,失去最佳的手术时机,严重影响预后,故早期发现、诊断及治疗是提高胃癌患者生存率,降低病死率的关键。该文将从传统及新型血清肿瘤标志物、内镜检查及基因水平三个方面对胃癌的诊断进展予以综述。

Gastric cancer is one of the most common malignant tumors, due to the lack of early gastric cancer clinical specificity, it is difficult to identify from benign gastric diseases, which often results in the high missed diagnosis and misdiagnosis rate of early gastric cancer , and missing the best operation time and seriously affecting the prognosis. Therefore early detection, diagnosis and treatment is the key to increase survival of the patients with gastric cancer and reduce mortality. Here is to make a review of the progress in diagnosis of gastric cancer from the perspectives of traditional and new type of serum tumor markers, endoscopy and gene level.
