Cancer Syndromes

Gastrointestinal cancer is one of the major causes of death worldwide. Hereditary gastrointestinal cancer syndromes constitute about 5-10% of all cancers. About 20-25% of undiagnosed cases have a possible hereditary component, which is not yet established. In the last few decades, the advance in genomics has led to the discovery of multiple cancer predisposition genes in gastrointestinal cancer. Physicians should be aware of these syndromes to identify high-risk patients and offer genetic testing to prevent cancer death. In this review, we describe clinical manifestations, genetic testing and its challenges, diagnosis and management of the major hereditary gastrointestinal cancer syndromes.Key words:  −  −  −  − .Abbreviations: ACG: American College of Gastroenterology; AFAP: attenuated FAP; APC: adenomatous polyposis coli; CDH1: E-cadherin; CHRPE: congenital hypertrophy of the retinal pigment epithelium; CRC: colorectal cancer; FAMMM: Familial atypical multiple mole melanoma; FAP: Familial adenomatous polyposis; GC: gastric cancer; HDGC: Hereditary diffuse gastric cancer; IHC: immunohistochemical; IPAA: ileal pouch–anal anastomosis; IRA: ileorectal anastomosis; MSI: microsatellite instability; MMR: mismatch repair; miRNA: micro RNA.

Mtorc1 Activation

Gastric cancer, as a malignant epithelial tumor, is a major health threat leading to poor overall survival and death. It is usually diagnosed at an advanced stage due to asymptomatic or only nonspecific early symptoms. The present study demonstrated that gankyrin contributes to the early malignant transformation of gastric cancer and can be selected to predict the risk of gastric cancer in those patients harboring the precancerous lesions (dysplasia and intestinal metaplasia). In addition, a new insight into gastric cancer was provided, which stated that gankyrin alleviates oxidative stress via mTORC1 pathway activation. It can potentiate the mTORC1 by PGK1-AKT signaling that promotes the tumor process, and this phenomenon is not completely consistent with the previous report describing colorectal cancer.

Abstract BACKGROUND Early diagnosis is very important to improve the survival rate of patients with gastric cancer, especially in asymptomatic participants. However, low sensitivity of common biomarkers has caused difficulties in early screening of gastric cancer. In this study, we explored whether MIC-1 can improve the detection rate of early gastric cancer.METHODS We screened 8,257 participants based on risk factors such as age, gender, and family history for physical examination including gastroscopy. Participant blood samples were taken for measure MIC-1, CA-199, CA72-4 and PG1/PG2 levels. The diagnostic performance of MIC-1 was assessed and compared with CA-199, CA72-4 and PG1/PG2, and its role in early gastric cancer diagnosis and the assessment of the risk of precancerous lesions have also been studied.RESULTS Based on endoscopic and histopathological findings, 55 participants had gastric cancer, 566 participants had low-grade neoplasia, 2605 participants had chronic gastritis. MIC-1 levels were significantly elevated in gastric cancer serum samples as compared to controls (p<0.001). The sensitivity of serum MIC-1 for gastric cancer diagnosis was much higher than that of CA-199 (49.1% vs. 20.0%) with similar specificities. Moreover, receiver operating characteristic (ROC) curve analysis also showed that serum MIC-1 had a better performance compared with CA-199, CA72-4 and PG1/PG2 in distinguishing early-stage gastric cancer (AUC: 72.9% vs. 69.5%, 67.5%, 44.0% respectively).CONCLUSIONS Serum MIC-1 is significantly elevated in most patients with early gastric cancer. MIC-1 can serve as a novel diagnostic marker of early gastric cancer and value the risk of gastric cancer.

The Relationship

Abstract The relationship between Uric acid (UA) and malignant tumor are still confusing. Gastric cancer(GC) is recognized to be closely related to Helicobacter pylori (H. pylori) infection, early diagnosis rate is very low. In this study, we aimed to investigate the relationship between H. pylori and hyperuricemia (HUA), and evaluate the predictive value of serum uric acid (SUA) in gastric precancerous lesion (GPL) and gastric cancer (GC). This retrospective study included 486 patients who underwent gastroscopy (155 controls, 272 GPL, 59 GC patients). The risk factors for GPL and GC were identified by multiple logistic regression analysis and nomogram was constructed to evaluate the ability of SUA to predict the risk of these diseases based on SUA score. We found that in healthy controls, HUA is positively correlated with H. Pylori (+). SUA was an independent risk factor for GPL and GC. Verification shows that the nomogram was better fitted for GC than for GPL. In conclusion, our study established nomogram based on SUA to predict the risk of GPL and GC, suggested that the incidence of GPL and GC is higher in H. pylori (+) HUA patients, so early intervention and vigilance should be raised.
