Currently, the diagnosis of atrophic gastritis and gastric cancer are mainly made by endoscopy and histopathology. Our study aimed to explore the practical value of Serum Pepsinogen I/II and gastrin-17 in gastric cancer diagnosis and prognosis. We collected 60 cases of gastric ulcer from February 2015 to November 2016 as gastric ulcer group, and 40 cases of gastric cancer treated in the same period as gastric cancer group. In 3  years after gastric cancer, 20 patients were served as postoperative gastric cancer group, and 70 healthy subjects as control group. The results showed that serum Pepsinogen I/II, gastrin-17, and other serum gastric function indexes were tested by enzyme-linked immunosorbent assay (ELISA). The serum PGI level of gastric ulcer group was higher than control group ( P  <  0.05). The serum G-17 concentrations in gastric ulcer group, gastric cancer group, and postoperative gastric cancer group were all higher than control group ( P  <  0.05). The area under receiver operating characteristic (ROC) curve of PGI screening was 0.905 and the best cutoff point was PGI  <  75  µg/L. Their sensitivity and specificity were 87.2% and 75.1%; the area under ROC curve of PGI/PGII rate screening was 0.761 and the best cutoff point was PGI/PGII  <  4. Their sensitivity and specificity were 88.9% and 62.3%. Multi logistical regression showed that the level of serum PGI, PGI, and G-17 and the odds ratio (OR) level of gastric cancer risk were 2.093, 2.653, and 0.494 ( P  <  0.05). The examination of Serum Pepsinogen I/II, gastrin-17, and other serum gastric function indexes can be used in the diagnosis and prognosis of gastric cancer and has a rather high practical value in monitoring recurrence in postoperative gastric cancer patients.

AbstractObjective:Gastric cancer is one of the most common malignancies worldwide. The risk factors for gastric cancer include environmental and genetic factors. Inflammation and the immune system are known to contribute to the development of the gastric cancer. We examined the influence of critical polymorphisms of CTLA-4 and CD28 genes and circulating protein levels on the etiology of gastric cancer.Methods:Genotyping of SNPs was performed in 55 gastric cancer patients and 105 healthy individuals using the PCR-RFLP method, and circulating levels of sCTLA-4 and sCD28 were measured.Results:There were no significant differences in the genotype and allele distributions of the evaluated SNPs [CTLA-4-318 C>T (rs5742909), CTLA-4+49 A>G (rs231775), CD28 C>T (rs3116496)] between gastric cancer patients and controls (p=0.36, p=0.78, and p=0.80, respectively). The circulating levels of sCTLA-4 and sCD28 were significantly different between the gastric cancer group and the control group (p<0.001 and p<0.001, respectively).Conclusion:The present results suggest that the CTLA-4 and CD28 gene polymorphisms that were evaluated do not play an important role in Turkish patients with gastric cancer. However, sCTLA4 and sCD28 levels were higher in cancer patients and may be useful as an auxiliary parameter in the diagnosis and monitoring of gastric cancer.

Background: Gastric cancer (GC) is the eighth most common cause of cancer deaths in Croatia and one of the most common causes of cancer deaths worldwide. A reliable diagnostic tool for the early detection of GC is essential. Objective: We previously suggested a pepsinogen test method to reduce the mortality from GC by allowing early detection. Here, we report an updated analysis from a prospective single-center clinical study to evaluate the sensitivity and specificity of the pepsinogen test method and to determine whether this test can be used as a part of routine laboratory assessment of high-risk patients. Methods: We present mature data of the pepsinogen test method in the Croatian population after a median follow-up of 36 months. Statistical analyses were performed using a Mann-Whitney U test, multiple logistic regression, and receiver operating characteristics (ROC) to evaluate the predictive power of the assayed biomarkers. Results: Of the 116 patients, 25 patients had GC and 91 demonstrated a nonmalignant pathology based on tissue biopsy. Cutoff values were pepsinogen I ⩽70 and pepsinogen I/II ratio ⩽3.0. Using ROC curve analysis, the accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were determined to be 87.22%, 78.12%, 90.10%, 71.43%, and 92.86%, respectively, for the diagnosis of GC. The area under the curve was 0.700 (95% confidence interval 0.57–0.83). Conclusion: Pepsinogen tests are valuable for screening a population in need of further diagnosis and could help to avoid unnecessary invasive endoscopic procedures.

Abstract Background One of the deadliest cancers in the world is gastric cancer. Long non-coding RNAs play prominent roles in cancer. LINC00961, TPT1-AS1, and SAMMSON have recently been discovered, which significantly contribute in various cancers and can affect the tumor size, grade of tumors and the metastasis condition. The aim of this study was to determine LINC00961, SAMMSON and TPT1-AS1 expression in gastric cancer tissues in comparison with healthy adjacent tissues. Methods The number of cancerous tissues and control groups was calculated to be at 40 (n = 40) and were analyzed by Quantitative real-time polymerase chain reaction. Results We found that overexpression of TPT1-AS1 and SAMMSON, and downexpression of LINC00961 in cancerous tissues in comparison with healthy adjacent tissues. A positive association between TPT1-AS1 and SAMMSON expression and tumor grade was observed. The level of mRNA folding change increased in cancer group compared to control group and *P < 0.05 is considered for mRNA folding change. Conclusion Finally, we found that overexpression of TPT1-AS1 and SAMMSON, and downexpression of LINC00961 were observed significantly in gastric cancer tissues in comparison with adjacent non-cancerous tissues. These lncRNAs were suggested as potential tumor markers for the diagnosis and treatment of gastric cancer.

AbstractPurposeWe aimed to determine optimal cut-off points of plasma levels of ghrelin and serum levels of pepsinogen I, II, and their ratio for screening of gastric cancer (GC).MethodsBlood samples were taken from 41 patients with confirmed gastric cancer along with 82 patients without malignancy. Serum levels of pepsinogen I and II, plus plasma levels of acylated ghrelin were measured using commercial ELISA kits.ResultsThe case group had significant lower plasma levels of ghrelin, pepsinogen I, and pepsinogen I/II ratio in comparison to the control group (P<0.001). In the control group, there was significant higher serum pepsinogen I (P=0.028) and pepsinogen II (P=0.003) and lower pepsinogen I/II ratio (P=0.020) in males versus females; significantly higher serum pepsinogen II (P=0.047) and lower pepsinogen I/II ratio (P=0.030) in overweight compared to normal weight patients; and significantly lower pepsinogen I/II ratio (P=0.030) in smokers versus non-smoker. In the case group, there was only significantly lower pepsinogen I (P=0.006) in males versus females, and significantly lower plasma ghrelin (P=0.017) in overweight compared to normal weight patients. The characteristic curve analysis indicated that pepsinogen I at a cut-off of 70.95 μg/L and pepsinogen I/II ratio at cut-off of 2.99, had good sensitivity and specificity.ConclusionsJust serums levels of pepsinogen I and the ratio of pepsinogen I/II can be used as biomarker to screen GC.

Abstract Background Gastric cancer, one of the most common cancers in the world, is a multifactorial disease in which environmental and genetic factors play a role. In our study, we aimed to determine the expression levels of four miRNAs (miR127-5p, miR-544a, miR-369-3p and miR-655-3p) on chromosome 14q32 in gastric cancer. Materials and methods Total RNA was isolated from blood samples taken from 66 gastric cancer and 66 healthy individuals. The gene expression levels determined by cDNA and quantitative real-time polymerase chain reaction were analyzed according to the 2−∆∆Ct method. SPSS 22 were used for statistical analysis and p < 0.05 was considered as statistically significant. Results and discussion miR-655-3p (fold change: 100, p = 0.026), miR-127-5p (fold change: 48, p < 0.001) and miR-369-3p (fold change: 1.6, p > 0.05) was less expressed in the gastric cancer group than control group. miR-544a was found 15.5-fold more expressed in the patient group than control group (fold change: 15.47, p < 0.001). Conclusion miR127-5p, miR-544a, and miR-655-3p may be evaluated as biomarkers in gastric cancer.

To explore exosomal miR-375 expression in gastric cancer patients and its relationship with patient prognosis. A total of 53 patients diagnosed with gastric cancer in our hospital from May 2014 to May 2016 were included as the gastric cancer group, and 46 healthy women who came to our hospital for physical examination during the same period were enrolled as the healthy group. Exosomal miR-375 expression level was detected using qRT-PCR, and the diagnostic performance and prognostic significance of exosomal miR-375 in gastric cancer were explored. The gastric cancer group showed increased exosomal miR-375 expression than the healthy group (P< 0.05); Kaplan-Meier survival analysis exhibited that serum exosomal miR-375 has an AUC of 0.778, sensitivity of 69.57%, and specificity of 75.47%, whereas Cox regression analysis showed that the miR-375 expression in exosomes was an independent risk factor affecting the prognosis of gastric cancer patients (P< 0.05). Patient with gastric cancer showed upregulated miR-375 expression in serum exosomes. Serum exosomal miR-375 was found to has positive sensitivity and specificity in the diagnosis of gastric cancer, which may be associated with poor prognosis of gastric cancer patients.
