胃癌总体预后较差,多与其病情已届晚期有关.如能早期诊断,胃癌的预后是可以改善的.早期胃癌是指病灶局限且深度不超过黏膜下层,不论有无淋巴结转移.广泛开展的内镜下切除术,甚至可以在早期取代外科手术.为了避免遗漏早期病变,仔细的内镜检查是必要的.然而,除了内镜之外,胃蛋白酶原等作为胃癌的生物标志物的研究在不同国家和地区相继开展,为我们早期胃癌的诊断另辟新径.
The overall prognosis of gastric cancer is poor, and its condition has been advanced .If the early diagnosis, the prognosis of gastric cancer can be improved.Early gastric cancer refers to the limitations of the lesion and depth does not exceed the submucosa, with or without lymph node metastasis. Microsurgery can even replace surgery in the early stages and careful endoscopy is necessary to avoid missing early lesions.However, in addition to endoscopy, the study of pepsinogen as a biomarker of gastric cancer varies Countries and regions have been carried out in order to provide a new path for our diagnosis of early gastric cancer.
