Purpose: Because of disease heterogeneity, limited studies on effective chemotherapies and therapeutic agents for advanced gastric cancer are available. Erythrocyte membrane protein band 4.1-like 5 (EPB41L5) has critical roles in renal and breast cancer metastasis. However, its role in metastatic gastric cancer remains unknown.
Experimental Design: The specimens of 78 gastric cancer patients were analyzed by oligonucleotide microarray and survival analysis. experiments and metastatic mice models were used to assess the effects of EPB41L5 on gastric cancer metastasis.
Results: Gastric cancer patients with high EPB41L5 levels had poor prognosis and low survival rate. Further, TGFβ1-induced EPB41L5 expression promoted gastric cancer cell migration and invasion by Smad-dependent TGFβ signaling. Phospho-Smad3 recruitment to the promoter was significantly inhibited by a TGFβ inhibitor. EPB41L5 overexpression increased lung metastasis of gastric cancer cells in nude mice, which was completely reversed by anti-EPB41L5 monoclonal antibody treatment. Importantly, p120-catenin knockdown abolished EPB41L5-enhanced gastric cancer cell metastasis. Anti-EPB41L5 monoclonal antibody treatment blocked the association of EPB41L5 with p120-catenin.
Conclusions: TGFβ/EPB41L5/p120-catenin axis regulates gastric cancer cell metastasis, and EPB41L5 is a promising therapeutic target for advanced gastric cancer.

Purpose: The aim of this study was to identify prognostic factors influencing overall survival (OS) in patients with gastric cancer treated with adjuvant chemoradiotherapy (CRT) and to develop a predictive model.
Methods: We retrospectively evaluated 245 non-metastatic gastric cancer patients who received adjuvant CRT or radiotherapy from 2010 to 2020. Survival analyses were performed using the Kaplan-Meier method.

Background: In this review, we aimed to compare the recommendations for Lynch syndrome (LS).
Methods: We compared the LS's guidelines of different medical societies, including recommendations for cancer surveillance, aspirin treatment, and universal screening.
Results: Most guidelines for LS patients recommend intervals of 1-2 years for performing colonoscopy, though there is disagreement regarding the age to begin CRC screening (dependent on status as a MLH1/MSH2 or MSH6/PMS2 carrier).

The dysregulation of microRNAs (miRNAs) has been detected in patients with gastric cancer (GC), which inspired the use of miRNAs as a novel biomarker for GC. In this study, we investigated the previously reported miRNA dysfunction in cancer tissues as a potential plasma biomarker for GC using quantitative reverse transcriptase polymerase chain reaction (RT-PCR). The published miRNA abnormalities were searched in the microRNA Cancer Association Database.

Background/objectives: Gastric intestinal metaplasia (GIM) is considered an irreversible preneoplastic precursor for gastric adenocarcinoma in adults. However, its significance in children and the long-term outcome remain poorly understood.
Methods: All children diagnosed with GIM between 2000 and 2020 were identified at a large tertiary referral centre.
