- W24920160 abstract "Objective To evaluate the value and inadequacy in clinical practice of the concept of gastric high-grade intraepithelial neoplasia (HIN). Methods Forty-five cases with gastric HIN diagnosed by the esophagogastroduodenoscopy (EGD) biopsy were treated from 2003 to 2009.The clinical and histopathological data were analyzed retrospectively. Results Radical surgeries were successfully performed on all the patients,among whom 33 underwent distal subtotal gastrectomy,3 proximal partial gastrectomy,7 total gastrectomy,and 2 endoscopic mucosal resection.In postoperative pathological examination,only 15 cases(33.3%) were HIN,while 14 cases(31.1%)were found to be early gastric cancers,and 16(35.6%)were advanced cancers.Twelve(40.0%)out of 30 cancers had regional lymph nodes metastasis.When the maximum diameter of the HIN lesion was greater than 3.0 cm,or when ulcer or the features of poorly-differentiated carcinoma or signet-ring cell carcinoma were present in preoperative biopsy,the likelihood of cancer in postoperative pathological examination was higher(P<0.05),and when malignancy was confirmed,the presence of the features above was associated with lymph nodes metastasis and advanced cancer. Conclusions Carcinoma is identified in a large proportion of patients with gastric HIN by the EGD biopsy.Lymph nodes metastasis or advanced cancer may be detected in these cases.Cautions must be taken when the new concept of HIN is widely used for diagnosing gastric lesion.Radical resection should be considered when the maximum diameter of the HIN lesion is greater than 3.0 cm,or when ulcer,or the feature of poorly-differentiated carcinoma or signet-ring cell carcinoma are present in the EGD biopsy.Key words: Stomach neoplasms; Hish-grade intraepithelial neoplasia; Diagnosis" @default.
