AIMTo investigate predictive markers for metachronous and synchronous gastric cancer (GC), which can develop after endoscopic submucosal dissection (ESD).METHODSA total of 352 patients underwent ESD for early GC at NTT West Osaka Hospital between June 2006 and February 2016. Exclusion criteria were as follows: Remnant stomach, unknown Helicobacter pylori status, and endoscopic observation of the whole stomach outside our hospital. We analyzed data from 192 patients comprising 109 patients with solitary GC (Group A) and 83 with metachronous and synchronous GC (Group B). We retrospectively investigated the clinicopathological and endoscopic characteristics, and endoscopic risk score as predictive markers for GC.RESULTSThe median age of Group B [72 years (interquartile range 63-78)] was significantly higher than that of Group A [66 years (interquartile range 61-74), respectively, P = 0.0009]. The prevalence of intestinal metaplasia in Group B tended to be higher than that in Group A (57.8% vs 45.0%, P = 0.08). The prevalence of gastric xanthoma (GX) in Group B was significantly higher than that in Group A (54.2% vs 32.1%, P = 0.003). The atrophy score in Group B was significantly higher than that in Group A (P = 0.005). Multivariate analysis revealed that higher age and the presence of GX were independently related to metachronous and synchronous GC [OR = 1.04 (1.01-1.08), P = 0.02; and OR = 2.11 (1.14-3.99), P = 0.02, respectively].CONCLUSIONThe presence of GX is a useful predictive marker for metachronous and synchronous GC.
Objective
The detection of early gastric cancer (GC) after
Helicobacter pylori
eradication is expected to increase in Japan. However, the predictive markers for early GC detected after
H. pylori
eradication have not been extensively studied. We conducted a retrospective, single-center observational study to investigate the predictive markers for early GC detected after
H. pylori
eradiation.
Methods
A total of 421 patients underwent endoscopic submucosal dissection for early GC at NTT West Osaka Hospital between June 2006 and August 2017. Data from patients with GC (Group C; n=70) and without GC (Group NC; n=114) after
H. pylori
eradication were analyzed.
Results
The proportion of men was significantly higher in Group C than in Group NC (92.9% vs. 65.8%; p<0.0001). Complications with other malignant diseases were more prevalent in Group C than in Group NC. A significantly greater proportion of patients had gastric xanthoma (GX) in Group C than in Group NC (64.3% vs. 14.9%; p<0.0001). Regarding scores for endoscopic findings related to the risk of GC, the atrophy score, intestinal metaplasia score and total score were significantly higher in Group C than in Group NC. A multivariate logistic regression analysis identified male sex, atrophy (open type), the presence of intestinal metaplasia and GX as independent predictors for early GC detected after
H. pylori
eradication. An atrophy-matched control analysis also identified GX as an independent predictor.
Conclusion
GX is a novel predictive marker for early GC detected after
H. pylori
eradication.
Abstract:A 62-year-old woman was admitted to our hospital with septic shock due to left submandibular osteomyelitis and cellulitis. Her condition improved following tooth extraction, drainage, and the administration of antibiotics. However, on the 4th day of hospitalization, she went into hemorrhagic shock after defecating a massive tarry stool. Emergency esophagogastroduodenoscopy (EGD) was performed. We found a giant ulcer at the antral greater curvature of the stomach. Computed tomography (CT) revealed that the gastric ulcer had penetrated the pancreas. She had no signs of peritonitis and had a bad general condition. She was therefore managed solely by conservative therapy. She recovered within days.
A 51-year-old woman had been taking proton pump inhibitor since August 2008. In May, 2016, endoscopic findings showed no atrophy and no intestinal metaplasia in the stomach, and multiple fundic gland polyps were identified in the stomach. A biopsy of a pedunculated polyp measuring 10 millimeters in diameter at the greater curvature of the middle gastric body demonstrated well differentiated tubular adenocarcinoma. In July 2016, we treated this lesion and two other semipedunculated polyps located near the first polyp and also measuring 10 mm in diameter by endoscopic mucosal resection. The final diagnosis of all lesions was a fundic gland polyp with low grade dysplasia and the cutting end was negative.
