Prognostic alternative splicing signatures and underlying regulatory network in esophageal carcinoma.

Prognostic alternative splicing signatures and underlying regulatory network in esophageal carcinoma. Am J Transl Res. 2019;11(7):4010-4028 Authors: Xie ZC, Wu HY, Ma FC, Dang YW, Peng ZG, Zhou HF, Chen G Abstract Alternative splicing (AS) has been widely reported to play an important role in cancers, including esophageal carcinoma (ESCA). However, no study has comprehensively investigated the clinical use of combination of prognostic AS events and clinicopathological parameters. Therefore, we collected 165 ESCA patients including 83 esophageal adenocarcinoma (EAC) and 82 esophageal squamous cell carcinoma (ESCC) patients from The Cancer Genome Atlas to explore the survival rate associated with seven types of AS events. Prognostic predictors for the clinical outcomes of ESCA patients were built. Predictive prognosis models of the alternative acceptor site in ESCA (area under the curve [AUC] = 0.83), alternative donor site in EAC (AUC = 0.99), and alternative terminator site in ESCC (AUC = 0.974) showed the best predictive efficacy. A novel combined prognostic model of AS events and clinicopathological parameters in ESCA was also constructed. Combined prognostic models of ESCA all showed better predictive efficacy than independent AS models or clinicopathological parameters model. Through constructing splicing regulatory network, the expression of AS factor was found to be negatively correlated with the most favorable AS events. Moreover, gene amplificatio...

This study evaluated the relationship of multimodality parameters derived from intravoxel incoherent motion method (IVIM), 18F- FDG-PET, CT perfusion and dynamic contrast enhanced MRI in patients with gastro- esophageal cancer and investigated their histopathological correlation. METHODS: Thirty-one consecutive patients (28 male; median age 63.9 years; range 37-84 years) with gastro-esophageal adenocarcinoma (n=22) and esophageal squamous cell carcinoma (n=9) were analyzed. IVIM parameters: pseudodiffusion (D*), perfusion fraction (fp), true diffusion (D) and the threshold b-value (bval); PET-parameters: SUVmax, metabo...

Conclusions The positive trends in the survival rate for esophageal patients could be due to adoption of multimodal therapy. Despite a lower proportion of advanced disease among patients over 80, they received less curative treatments compared with other age groups. Further studies are required to identify strategies to maximize survival for patients with stage IV disease, and patients 80 years and older.

Conclusions: Neoadjuvant radiation dose impacts pathological response in terms of pMR in oesophageal cancer patients. No radiation dose-response effect was observed for pCR. Further prospective trials are needed to investigate the dose-response relation in terms of pCR. PMID: 31432736 [PubMed - as supplied by publisher]

Esophageal cancer is a highly lethal disease, especially in developing countries. China has been a high-incidence area of esophageal cancer for many years and accounts for over 50% of the global morbidity and mortality [1]. The two major histological types of esophageal cancer are squamous cell carcinoma (ESCC) and adenocarcinoma, and there is a striking geographical variation in the incidence of the esophageal cancer subtypes. In China, approximately 90% of patients with esophageal cancer are diagnosed with ESCC [2].

Authors: Hao J, Li S, Li J, Jiang Z, Ghaffar M, Wang M, Jia R, Chen S, Wang Y, Zeng Y Abstract Esophageal carcinoma (EC) is the sixth most deadly of all cancers. It is among the most malignant cancers due to its highly aggressive nature and low survival rate. The incidence of EC is high in Asia, particularly in Southern areas including China, Iran and Japan. There is a large body of evidence to suggest an association between the melanoma antigen gene (MAGE) family and the initiation of cancer; however, there is no clear evidence to suggest an association between EC and MAGE. Discovery of the chemical and physiologi...

Authors: Kelly RJ Abstract Esophageal cancer has a poor prognosis, with 5-year survival rates ranging from 20% to 35% in the nonmetastatic setting. Despite advances in surgical techniques and optimization of chemoradiotherapy regimens, overall survival benefits have been incremental at best. Esophageal cancer requires a concerted multidisciplinary approach, perhaps more so than any other tumor type given the integral role played by the esophagus in maintaining calorific intake and the propensity for early spread through the lymphatics. This review describes the latest in surgical techniques to minimize postoperativ...

We presented the expressions of each member in miR-200 family in 15 types of cancer by boxplot, and analyzed the correlation among the members of miR-200 family by Spearman method. Different subgroup analyses were then performed based on the correlation among the members of miR-200 family, and the publication bias was assessed using the funnel plot of the Egger bias indicator test. RESULTS: Of 36 articles, including 15 tumor types and 4644 patients were included to perform meta-analysis. It was found that miR-200 family members can be used as independent protective factors in patients with various tumors but the miR-2...

Abstract With the increasing awareness of heterogeneity in cancers, better prediction of cancer prognosis is much needed for more personalized treatment. Recently, extensive efforts have been made to explore the variations in gene expression for better prognosis. However, the prognostic gene signatures predicted by most existing methods have little robustness among different datasets of the same cancer. To improve the robustness of the gene signatures, we propose a novel high-frequency sub-pathways mining approach (HiFreSP), integrating a randomization strategy with gene interaction pathways. We identified a six-g...
