EGFR-dependent delivery of phosphorylated IGFBP3 by cancer stem cells drives chemotherapy resistance in colorectal cancer

The primary systemic treatment for advanced colorectal cancer (CRC) is chemotherapy, but inevitable drug resistance leads to poor prognosis. Cancer stem cells (CSCs) are recognized as significant contributors to chemotherapy resistance, yet the mechanisms underlying their ability to induce widespread...

4-Methylumbelliferone for type 1 diabetes therapy: evidence for β-cell protection via EGFR/PI3K/Akt signaling

AbstractPurpose Type 1 diabetes mellitus (T1DM) results from autoimmune-mediated destruction of pancreatic β-cells, leading to absolute insulin deficiency. Current treatments rely on insulin replacement and do not prevent β-cell loss. 4-Methylumbelliferone (4-MU), an inhibitor of hyaluronan synthesis, has shown anti-inflammatory...

Acquired resistance to first-line osimertinib is heterogeneous in EGFR-mutant advanced non-small cell lung cancer

Osimertinib, a third-generation EGFR tyrosine kinase inhibitor (EGFR-TKI), has shown remarkable efficacy in EGFR-mutant non-small cell lung cancer (NSCLC). However, acquired resistance remains inevitable. This study aimed to explore the underlying resistance mechanisms and evaluate second-line treatment strategies to improve...

Optimal treatment strategies for unresectable stage III EGFR-mutated non-small cell lung cancer: a systematic review and Bayesian network meta-analysis

BackgroundThe PACIFIC regimen (consolidation durvalumab following chemoradiotherapy) is the standard of care for unresectable stage III non-small cell lung c Abstract Background: The PACIFIC regimen (consolidation durvalumab following chemoradiotherapy) is the standard of care for unresectable stage III non-small cell...

Survival outcomes and a prognostic nomogram in EGFR-mutant non-small cell lung cancer with leptomeningeal metastasis: a real-world cohort study

AbstractPurpose Leptomeningeal metastasis (LM) carries a poor prognosis in EGFR-mutant non-small cell lung cancer (NSCLC). This study aims to explore clinical features and survival outcomes and develop a nomogram for overall survival (OS) in this population. Methods We retrospectively enrolled...

Clinical Outcomes of Second-Line FOLFIRI Plus Ramucirumab According to Prior Biologic Exposure in Metastatic Colorectal Cancer: A Retrospective Comparison of Prior Bevacizumab and Prior Anti-EGFR Cohorts

AbstractPurpose Ramucirumab plus FOLFIRI is an established second-line treatment option for metastatic colorectal cancer (mCRC) after oxaliplatin-based first-line therapy. However, real-world data comparing outcomes according to prior biologic exposure are limited. Methods We retrospectively reviewed patients with mCRC who received...

Habitat model based on CEUS for noninvasive prediction of EGFR mutation status in peripheral NSCLC

AbstractBackground To develop and validate a contrast-enhanced ultrasound (CEUS)-based habitat model for noninvasive prediction of epidermal growth factor receptor (EGFR) mutation status in patients with peripheral non-small cell lung cancer (NSCLC). Methods This retrospective study included 187 patients with NSCLC...

Racura Oncology Doses First Patient in Phase 1 HARNESS-1 Trial of RC220 in EGFR-Mutant Non-Small Cell Lung Cancer

Racura Oncology has dosed the first patient in the HARNESS-1 Phase 1a/b trial of RC220 in combination with osimertinib for EGFR-mutant non-small cell lung cancer. The study will assess safety, pharmacokinetics, ctDNA dynamics and early clinical activity of RC220 as...
