Compelling shreds of evidence derived from both clinical and experimental research have demonstrated the crucial contribution of receptor for advanced glycation end products(RAGE)axis activation in the development of neoplasms,including gastric cancer(GC).This new actor in tumor biology plays an important role in the onset of a crucial and long-lasting inflammatory milieu,not only by supporting phenotypic changes favoring growth and dissemination of tumor cells,but also by functioning as a pattern-recognition receptor in the inflammatory response to Helicobacter pylori *** the present review,we aim to highlight how the overexpression and activation of the RAGE axis contributes to the proliferation and survival of GC cells as and their acquisition of more invasive phenotypes that promote dissemination and ***,the contribution of some single nucleotide polymorphisms in the RAGE gene as susceptibility or poor prognosis factors is also discussed.

Introduction The Society for Vascular Surgery recommends treating nonruptured splenic artery aneurysms(SAAs)of>3 cm with a demonstrable increase in size or with associated symptoms[1].Percutaneous intervention with embolization coils or covered stents has become popular due to its high technical success rates and low morbidity[2,3].

BACKGROUND Owing to rarity of disease and lack of prospective studies, data supporting the role of adjuvant chemotherapy in ampulla of Vater(AoV) carcinoma is *** To evaluate whether adjuvant chemotherapy cases for AoV carcinoma had better disease-free survival(DFS) rates than cases of observation following curative *** We retrospectively analyzed the association between adjuvant chemotherapy and DFS and overall survival(OS) in patients with stage IB-Ⅲ AoV carcinoma who underwent curative surgical resection. Fluorouracil-based adjuvant chemotherapy was administered after surgery at the discretion of the physician. Adjusted multivariate regression models were used to evaluate the association between adjuvant chemotherapy and survival *** Of the total 104 patients who underwent curative surgery, 52 received adjuvant chemotherapy. Multivariate analysis revealed that higher histologic grade [hazard ratio(HR) = 2.24, P = 0.046], advanced tumor stage(HR = 1.85, P = 0.030), and vascular invasion(HR = 2.14, P = 0.010) were associated with shorter DFS. Adjuvant chemotherapy improved DFS compared to the observation group(HR =0.50, P = 0.015) and tended to be associated with a longer OS, although the difference was not statistically significant(HR = 0.58, P = 0.098).CONCLUSION Among patients with resected AoV carcinoma, the adjuvant chemotherapy group was not associated with a significant survival benefit compared to the observation group. However, on multivariate analysis adjusting for prognostic factors, adjuvant chemotherapy following surgery was an independent prognostic factor for DFS in patients with resected AoV carcinoma. Further studies are needed to investigate the effectiveness of adjuvant chemotherapy according to histologic phenotype.
