Microvessel density is a prognostic marker of human gastric cancer

AIM: To investigate whether microvessel density (MVD) is related with prognosis in gastric cancer patients, and the expression of cyclooxygenase-2 (COX-2) and vessel endothelial growth factor (VEGF) so as to determine the possible role of COX-2 and VEGF in gastric cancer angiogenesis.METHODS: Forty-seven formalin-fixed paraffin-embedded tissue samples of gastric cancer were evaluated for COX-2, VEGF by immunohitochemical staining. To assess tumor angiogenesis, MVD was determined by immunohitochemical staining of endothelial protein factor Ⅷ-related antigen. The relationship among COX-2 and VEGF expression, MVD, and clinicopathologic parameters was analyzed. RESULTS: Among the 67 samples, high MVD was significantly associated with lymph node metastasis and poor survival. Multivariate survival analysis showed that MVD value and lymph node metastasis were independent prognostic factors. The expression rate of COX-2 and VEGF was significantly higher than that of the adjacent tissues. COX-2 and VEGF expression in gastric cancer was significantly correlated with tumor differentiation and depth of invasion, but not with survival. The mean MVD value of COX-2 or VEGF positive tumors was higher than that of COX-2 or VEGF negative tumors. A significant correlation was found between the expressions of COX-2and VEGF. CONCLUSION: MVD may be one of the important prognostic factors for gastric cancer patients. COX-2 and VEGF may play an important role in tumor progression by stimulating angiogenesis. VEGF might play a main role in the COX-2 angiogenic pathway. The inhibition of angiogenesis or COX-2, VEGF activity may have an important therapeutic benefit in the control of gastric cancer.

Gastroesophageal reflux disease management according to contemporary international guidelines:A translational study

AIM:To test the Genval recommendations and the usefulness of a short trial of proton pump inhibitor(PPI) in the initial management and maintenance treatment of gastroesophageal reflux disease(GERD)patients. METHODS:Five hundred and seventy seven patients with heartburn were recruited.After completing a psychometric tool to assess quality of life(PGWBI)and a previously validated GERD symptom questionnaire (QUID),patients were grouped into those with esophagitis(EE,n=306)or without mucosal damage (NERD,n=271)according to endoscopy results. The study started with a 2-wk period of high dose omeprazole(omeprazole test);patients responding to this PPI test entered an acute phase(3 mo)of treatment with any PPI at the standard dose.Finally,those patients with a favorable response to the standard PPI dose were maintained on a half PPI dose for a further 3-mo period. RESULTS:The test was positive in 519(89.9%)patients,with a greater response in EE patients(96.4%) compared with NERD patients(82.6%)(P=0.011). Both the percentage of completely asymptomatic patients,at 3 and 6 mo,and the reduction in heartburn intensity were significantly higher in the EE compared with NERD patients(P<0.01).Finally,the mean PGWBI score was significantly decreased before and increased after therapy in both subgroups when compared with the mean value in a reference Italian population. CONCLUSION:Our study confirms the validity of the Genval guidelines in the management of GERD patients. In addition,we observed that the overall response to PPI therapy is lower in NERD compared to EE patients.

Ruptured high flow gastric varices with an intratumoral arterioportal shunt treated with balloon-occluded retrograde transvenous obliteration during temporary balloon occlusion of a hepatic artery

A patient presented with hematemesis due to gastric variceal bleeding with an intratumoral arterioportal shunt. Contrast-enhanced CT revealed gastric varices and hepatocellular carcinoma with tumor thrombi in the right portal vein. Angiography and angio-CT revealed a marked intratumoral arterioportal shunt accompanied with reflux into the main portal vein and gastric varices. Balloon-occluded retrograde venography from the gastro-renal shunt showed no visualization of gastric varices due to rapid blood flow through the intratumoral arterioportal shunt. The hepatic artery was temporarily occluded with a balloon catheter to reduce the blood flow through the arterioportal shunt, and then concurrent balloon-occluded retrograde transvenous obliteration （BRTO） was achieved. Vital signs stabilized immediately thereafter, and contrast-enhanced CT revealed thrombosed gastric varices. Worsening of hepatic function was not recognized. BRTO combined with temporary occlusion of the hepatic artery is a feasible interventional procedure for ruptured high flow gastric varices with an intratumoral arterioportal shunt.

Ankaferd hemostat in the management of gastrointestinal hemorrhages

Gastrointestinal (GI) bleeding refers to any hemorrhage ascribed to the pathologies of the gastrointestinal tract,extending from the mouth to the anal canal.Despite the recent improvements in the endoscopic,hemostatic and adjuvant pharmacologic techniques,the reported mortality is still around 5%-10% for peptic ulcer bleeding and about 15%-20% for variceal hemorrhages.Although endoscopic management reduces the rates of re-bleeding,surgery,and mortality in active bleeding;early recurrence ratios still occur in around 20% of the cases even with effective initial hemostatic measures.In this quest for an alternative pro-hemostatic agent for the management of GI bleedings,Ankaferd blood stopper (ABS) offers a successful candidate,specifically for "difficult-to-manage" situations as evidenced by data presented in several studies.ABS is a standardized mixture of the plants Thymus vulgaris,Glycyrrhiza glabra,Vitis vinifera,Alpinia officinarum,and Urtica dioica.It is effective in both bleeding individuals with normal hemostatic parameters and in patients with deficient primary and/or secondary hemostasis.ABS also modulates the cellular apoptotic responses to hemorrhagic stress,as well as hemostatic hemodynamic activity.Through its effects on the endothelium,blood cells,angiogenesis,cellular proliferation,vascular dynamics,and wound healing,ABS is now becoming an effective alternative hemostatic medicine for gastrointestinal bleedings that are resistant to conventional anti-hemorrhagic measurements.The aim of this review is to outline current literature experience suggesting the place of ABS in the management of GI bleeding,and potential future controlled trials in this complicated field.

Is ineffective esophageal motility associated with gastropharyngeal reflux disease?

AIM： TO evaluate the association between IEM and gastropharyngeal reflux disease （GPRD） in patients who underwent ambulatory 24-h dual-probe pH monitoring for the evaluation of supraesophageal symptoms. METHODS： A total of 632 patients who underwent endoscopy, esophageal manometry and ambulatory 24-h dual-pH monitoring due to supraesophageal symptoms （e.g. globus, hoarseness, or cough） were enrolled. Of them, we selected the patients who had normal esophageal motility and IEM. The endoscopy and ambulatory pH monitoring findings were compared between the two groups. RESULTS;： A total of 264 patients with normal esophageal motility and 195 patients with the diagnosis of IEM were included in this study. There was no difference in the frequency of reflux esophagitis and hiatal hernia between the two groups. All the variables showing gastroesophageal reflux and gastropharyngeal reflux were not different between the two groups. The frequency of GERD and GPRD, as defined by ambulatory pH monitoring, was not different between the two groups. CONCLUSION： There was no association between IEM and GPRD as well as between IEM and GERD. IEM alone cannot be considered as a definitive marker for reflux disease.

Eosinophilic esophagitis

Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power fi eld. In addition, it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modifications, topical corticosteroids and endoscopic dilation can be used alone or in combination.
