Previous studies have shown that statins reduce the risk of gastric cancer; however, their role has not been adequately studied in patients without infection. We aimed to investigate whether statins reduced the risk of metachronous gastric cancer (GC) in -negative patients who underwent endoscopic resection for early gastric cancer (EGC). Retrospective data of 2153 patients recruited between January 2007 and December 2016, with no infection at baseline, who underwent resection for EGC, were analyzed. Metachronous GC was defined as a newly developed GC at least 1 year after endoscopic resection. Patients who used statins for at least 28 days during the follow-up period were considered as statin users. During a median follow-up of 5 years (interquartile range, 3.5-6.2), metachronous GC developed in 165 (7.6%) patients. In the multivariate Cox regression analysis, statin use was an independent factor associated with GC recurrence (adjusted hazard ratio (HR), 0.46; 95% confidence interval (CI), 0.26-0.82). Moreover, the risk of GC reduced with increasing duration (<3 years: HR 0.40, 95% CI 0.14-1.13; ≥3 years: HR 0.21, 95% CI 0.05-0.90; trend = 0.011) and the dose of statin (cumulative defined daily dose (cDDD) < 500: HR 0.45, 95% CI 0.16-1.28; cDDD ≥ 500: HR 0.19, 95% CI 0.04-0.80; trend = 0.008) in the propensity score-matched cohort. Statin use was associated with a lower risk of GC recurrence in -negative patients with resected EGC in a dose-response relationship.

Expression Patterns of DLL3 Across Neuroendocrine and Non-Neuroendocrine Neoplasms Reveal Broad Opportunities for Therapeutic Targeting.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.
Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).

The Warburg effect, a common feature of solid tumors, rewires the metabolism and promotes growth, survival, proliferation, and long-term maintenance in gastric cancer (GC). We performed in vitro and in vivo studies of the pathogenesis of GC to investigate the effects and mechanism of LINC01224 in this cancer. qRT-PCR was used to measure the expression of LINC01224 or miR-486-5p in GC cells, and the expression of LINC01224 in GC tissues by FISH (Fluorescence in situ hybridization) analysis was evaluated.

Background: Gastric cancer (GC) ranks as the fourth leading cause of cancer-related deaths worldwide, with most patients diagnosed at advanced stages due to the absence of reliable early detection biomarkers.
Methods: RNA-sequencing was conducted to identify the differentially expressed genes between GC tissues and adjacent normal tissues. CCK8, EdU, colony formation, transwell, flow cytometry and xenograft assays were adopted to explore the biological function of ZBTB10 and betulinic acid (BA) in GC progression.
