胃癌是全球四大恶性肿瘤之一,2012年调查显示胃癌在我国的发病率和死亡率分别居第2位和第3位。我国胃癌死亡人数约占全球该病死亡人数的1/4,每年新增胃癌患者约40万,病死人数约30万[1]。目前对于胃部疾病的检查,多采用内镜活检和超声内镜及内镜下染色的综合应用,临床诊断胃癌的可靠依据是病理组织学诊断。病理医生使用光学显微镜对胃组织切片进行观察,根据多年经验做出诊断,具有一定的主观性,个体差异性大。而计算机图像分析能够将定性指标转换为定量数据,对胃高分化
Gastric cancer is one of the four major malignancies in the world. According to the survey in 2012, the incidence and mortality of gastric cancer in China ranked No. 2 and No. 3, respectively. The death toll of gastric cancer in China accounts for about 1/4 of the global death toll of the disease. About 400,000 new gastric cancer patients are newly added each year, and the number of deaths is about 300,000 [1]. Currently for the examination of gastric diseases, and more use of endoscopic biopsy and endoscopic ultrasound and endoscopic staining of the integrated application of a reliable basis for clinical diagnosis of gastric cancer is histopathological diagnosis. Pathologists use optical microscopy of gastric tissue sections to observe, based on years of experience to make a diagnosis, has a certain subjectivity, individual differences. The computer image analysis can be qualitative indicators into quantitative data on gastric hyperplasia
