Purpose There is currently no standard treatment strategy for patients with advanced metastatic gastric cancer experiencing progression after two or more lines of chemotherapy. We assessed the efficacy and safety apatinib, a novel vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor, in gastroesophageal junction adenocarcinoma whom at least prior chemotherapy had failed. Patients Methods This was randomized, double-blind, placebo-controlled phase III trial. from 32 centers...

Patients with metastatic gastric cancer (mGC) who do not respond to or experience progression second-line chemotherapy have no treatment options that clearly confer a survival benefit. This trial investigated the safety and efficacy of apatinib, an inhibitor vascular endothelial growth factor receptor, as option for heavily pretreated patients mGC.Patients experienced failure at least two chemotherapeutic regimens were randomly assigned receive placebo (group A), apatinib 850 mg once daily...

Reliable biomarkers of apatinib response in gastric cancer (GC) are lacking. We investigated the association between early presence common adverse events (AEs) and clinical outcomes metastatic GC patients. conducted a retrospective cohort study using data on 269 apatinib-treated patients two trials. AEs were assessed at baseline until 28 days after last dose apatinib. Clinical compared with without hypertension (HTN), proteinuria, or hand foot syndrome (HFS) first 4 weeks. Time-to-event...

Neuroblastoma (NB) is the most common pediatric solid tumor that originates from neural crest-derived sympathoadrenal precursor cells are committed to development of sympathetic nervous system. The well differentiated histological phenotype NB has been reportedly associated with favorable patient outcome. Retinoic acid (RA) can effectively induce cell differentiation, thereby being used in clinic as a treatment agent for inducing differentiation high-risk NB. However, underlying molecular...

Abstract Fulminant hepatic failure (FHF) is a potentially fatal liver disease that associated with intrahepatic infiltration of inflammatory cells. As the receptor polyunsaturated long chain fatty acids, GPR120 can regulate cell differentiation, proliferation, metabolism, and immune response. However, whether involved in FHF remains unknown. Using Propionibacterium acnes ( P. )-primed, LPS-induced mice, we found interference activity using pharmacological agonist attenuated severity injury...

Aberrant expression of a zinc transporter ZIP4 in pancreatic ductal adenocarcinoma (PDAC) has been shown to contribute tumor progression and is potential target for individualized therapy. The overall objective this study was determine whether could serve as novel diagnostic prognostic marker human PDAC, if it can be assessed by minimally invasive sampling using endoscopic ultrasound guided fine needle aspiration (EUS-FNA). Immunohistochemistry performed compare the PDAC samples obtained...

Pancreatic cancer is one of the leading causes cancer-related mortality in both developed and developing countries. The incidence pancreatic China accounts for about a quater global incidence, epidemiological characteristics therapeutic strategies differ due to social, economic, cultural, environmental, public health factors. Non-domestic guidelines do not reflect clinicopathologic treatment patterns Chinese patients. Thus, 2018, Society Clinical Oncology (CSCO) organized panel senior...

KRAS is widely mutated in human cancers, resulting unchecked tumor proliferation and metastasis, which makes identifying KRAS-targeting therapies a priority. Herein, we observe that mutant specifically promotes the formation of ERK2-p53 complex stomach/colorectal cells. Disruption this by applying MEK1/2 ERK2 inhibitors elicits strong apoptotic responses p53-dependent manner, validated genome-wide knockout screening. Mechanistically, p53 physically associates with phosphorylated through...
