GE11 surface modification onto GO significantly increased the cellular uptake of GO in EGFR overexpressed oesophageal cancer cells (KYSE-30 and EC109 cells) than that of normal cells, indicating the EGFR targeting effects of Ori@GE11-GO.
These phase 3 trial results point to little benefit to current EGFR-targeted agents in an unselected patient population, and highlight the need for predictive biomarkers in the treatment of esophageal cancer.
This cancer-targeted design of Se NPs provides a new strategy for synergistic treating of cancer with higher efficacy and reduced side effects, introducing GE11-Ori-Se NPs as a candidate for further evaluation as a chemotherapeutic agent for EGFR over-expressed esophageal cancers.
A ligand-based and enediyne-energized bispecific fusion protein targeting epidermal growth factor receptor and insulin-like growth factor-1 receptor shows potent antitumor efficacy against esophageal cancer.
Methods A prespecified, blinded molecular analysis of Cancer Esophagus Gefitinib trial tumors was conducted to compare efficacy of gefitinib with that of placebo according to EGFR copy number gain (CNG) and EGFR, KRAS, BRAF, and PIK3CA mutation status.
Real-time quantitative polymerase chain reaction technology (RT-PCR) was used to detect the expression of VEGF, HER-2, and EGFR mRNA in esophageal squamous cancer tissue of 60 cases and 30 cases of VEGF, HER-2, and EGFR mRNA in esophageal cancer adjacent tissues, and analyze its relationship with clinicopathological features.
More than 50% EGFR-positive EsC and MPM cells were resistant to EGFR-TKI, and susceptibility to EGFR-TKI growth-inhibitory effect correlated positively with expression of E-cadherin (epithelial gene marker) and negatively with mesenchymal gene markers.
In this report, the effect of PYM on EGFR expression in human esophageal cancer cells and the therapeutic efficacy of the combination of PYM and cetuximab on esophageal cancer xenograft were investigated.
We report the outcome in a series of esophageal cancer patients treated at our center and the results of a retrospective analysis of epidermal growth factor receptor (EGFR) expression and EGFR/HER2 gene copy numbers taken as possible prognostic and predictive factors.
We evaluated the antitumor effects of lapatinib, a dual tyrosine kinase inhibitor which simultaneously inhibits EGFR and HER2, 5-fluorouracil (5-Fu) alone and in combination on esophageal cancer cells.
