| 1 | Endoscopic features suggesting gastric cancer in biopsy-proven gastric adenoma with high-grade neoplasia显示文摘AIM:To elucidate the endoscopic features that predict the cancer following endoscopic submucosal dissection(ESD)in patients with high-grade neoplasia(HGN).METHODS:We retrospectively analyzed the medical records of patients who underwent ESD of gastric neoplasms from January 2007 to September 2010.ESD was performed in 555 cases involving 550 patients.A total of 112 lesions from 110 consecutive patients were initially diagnosed as HGN without cancer by forceps biopsy,and later underwent ESD.We classified lesions into two groups according to histologic discrepancies between the biopsy and ESD diagnosis.Gastric adenoma in the final diagnosis by ESD specimens were defined as adenoma group.Lesions with coexisting cancer after ESD were defined as cancer group.RESULTS:The mean age was 65.3 years,and 81 patients were male.There was no significant difference in the age or gender distribution between the adenoma(n=52)and cancer(n=60)groups.Thirty-six of these lesions(32.1%)showed histologic concordance between the forceps biopsy and ESD specimens,16(14.3%)showed a downgraded histology(low-grade neoplasia),and 60(53.6%)showed an upgraded histology(cancer).A red color change of the mucosal surface on endoscopy was found in 27/52(51.9%)of cases in the adenoma group and in 46/60(76.7%)of cases in the cancer group(P=0.006).Ulceration of the mucosal surface on endoscopy was found in 5(9.6%)of 52 lesions in the adenoma group and in 17(28.3%)of 60 lesions in the cancer group(P=0.013).In the multivariate analysis,a reddish surface color change and mucosal ulceration were significant predictive factors correlated with cancer after ESD of the HGN by forceps biopsy.CONCLUSION:HGN with a red color change or mucosal ulceration correlated with the presence of gastric cancer.These finding may help to guide the diagnosis and treatment. | Jung Ho Kim Yoon Jae Kim Jungsuk An Jong Joon Lee Jae Hee Cho Kyoung Oh Kim Jun-Won Chung Kwang An Kwon Dong Kyun Park Ju Hyun Kim | 2014 | World Journal of Gastroenterology2014，20，34： | 10 |

| 3 | A case of Cowden syndrome diagnosed from multiple gastric polyposis显示文摘Cowden syndrome is a rare autosomal dominant disorder that is characterized by multiple hamartomas in a variety of tissues and this is associated with germline mutations in the phosphatase and tensin homologue (PTEN) gene, which is the tumor suppressor gene located on chromosome 10q23.3. It is characterized by multiple hamartomatous neoplasms of the skin, oral mucosa, gastrointestinal (GI) tract, bones, central nervous system, eyes, and genitourinary tract. Cowden syndrome does not have increased risk of GI malignancy; however, it has an increased risk of breast, thyroid and endometrial cancer development. Herethe authors report a rare case of Cowden syndrome incidentally diagnosed from multiple gastric polyposis. A 29-year-old woman presented with multiple gastric polyps. The laboratory results were normal except for mild anemia, with a hemoglobin level of 11.9 g/dL. Esophagogastroduodenoscopy revealed multiple gastric, duodenal polyps and esophageal acanthosis. Colonoscopy revealed possible hamartomatous polyps in the rectum. Under the suspicion of Cowden syndrome, sonography of the thyroid and breasts was carried out, which revealed multiple thyroid masses. Subsequent fine-needle aspiration biopsy revealed the presence of clusters of follicular epithelial cells, and due to the possibility of malignancy, the patient underwent total thyroidectomy. The pathology was reported as invasive follicular carcinoma. A gene study by direct sequencing showed the presence of a PTEN mutation (c.633C > A /p.Cys211*). | Minsu Ha Jun Won Chung Ki Baik Hahm Yoon Jae Kim Dong Kyu Kim Myeong Gun Kim Woochang Lee Jungsuk An | 2012 | World Journal of Gastroenterology2012，18，8： | 1 |
| 4 | A feasible modified biopsy method for tissue diagnosis of gastric subepithelial tumors显示文摘AIM: To evaluate the diagnostic yield and safety of a modified technique for the histological diagnosis of subepithelial tumors (SETs). METHODS: A retrospective review of patients who underwent a modified technique for the histological diagnosis of gastric SETs, consisting of a mucosal incision with a fixed flexible snare (MIF) and deep-tissue biopsy under conventional endoscopic view, from January 2012 to January 2013 was performed. Eleven patients with gastric SETs 10-30 mm in diameter and originating from the third or fourth layer on endoscopic ultrasonography were included. RESULTS: The mean age was 59.8 (range, 45-76) years, and 5 patients were male. The mean size of the SETs was 21.8 (range, 11-30) mm. The number of biopsy specimens was 6.3 (range 5-8). The mean procedure time was 9.0 min (range, 4-17 min). The diagnostic yield of MIF biopsies was 90.9% (10/11). The histological diagnoses were leiomyoma (4/11, 36.4%), aberrant pancreas (3/11, 27.3%), gastrointestinal stromal tumors (2/11, 18.2%), an inflammatory fibrinoid tumor (1/11, 9.1%); one result was non-diagnostic (1/11, 9.1%). There were six mesenchymal tumors; the specimens obtained in each case were sufficient for an immunohistochemical diagnosis. There was no major bleeding, but one perforation occurred that was successfully controlled by endoscopic clipping. CONCLUSION: The MIF biopsy was simple to perform, safe, and required a shorter procedure time, with a high diagnostic yield for small SETs. | Jung Ho Kim Jun-Won Chung Minsu Ha Min Young Rim Jong Joon Lee Jungsuk An Yoon Jae Kim Kyoung Oh Kim Kwang An Kwon Dong Kyun Park Yeon Suk Kim Duck Joo Choi | 2013 | World Journal of Gastroenterology2013，19，29： | 0 |
