Abstract Background: Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors have transformed the management of hormone receptor–positive/HER2–negative (HR+/HER2–) advanced breast cancer, yet evidence for elderly or poor-performance patients remains limited. This study examined real-world outcomes of palbociclib plus endocrine therapy in Asian patients, with additional subgroup analyses by age and performance status. Methods: We retrospectively analyzed 46 consecutive Asian patients with recurrent or de novo HR+/HER2− breast cancer treated with first-line palbociclib plus ET between April 2021 and March 2025. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall response rate (ORR), disease control rate (DCR), and safety.… More >

Abstract Background: The most aggressive forms of breast cancer are characterized by independence from steroid hormones but a strong dependence on growth factors. In such cancer cells, oncogenic receptors, including human epidermal growth factor receptor 2 (HER2), are activated, and their targeted inhibition represents an attractive therapeutic strategy. The study aimed to develop small-molecule potential dual heat shock protein 90 (HSP90)-HER2 inhibitors and evaluate them as anticancer agents in HER2-positive cells. Methods: The research project involved obtaining a series of compounds with potential dual inhibitory activity against HSP90 and HER2 by targeted organic synthesis, which was… More > Graphic Abstract

Abstract Cholangiocarcinoma (CCA) is a fatal bile duct malignancy. CCA is intrinsically resistant to standard chemotherapy, responds poorly to it, and has a poor prognosis. Effective treatments for cholangiocarcinoma remain elusive, and a breakthrough in CCA treatment is still awaited. The human epidermal growth factor receptor 2 (HER2) plays an oncogenic role by promoting an aggressive cancer phenotype through multiple pathways. While HER2 has shown increasing potential as an effective target for breast and gastric cancers over the last decade, this has not been the case for CCA. This review explores the possibility of targeting HER2 More > Graphic Abstract

Abstract Background: The use of third-generation different tyrosine kinase inhibitors (TKIs) is considered the most effective option for treating advanced non-small cell lung cancer (aNSCLC) with epidermal growth factor receptor (EGFR) mutations. However, there is limited information on the efficacy and safety of aumolertinib in patients remains these cases. Methods: The clinical records of patients receiving aumolertinib as first-line therapy across four hospitals in the Guangxi Zhuang Autonomous Region from April 2020 to December 2021 were retrospectively analyzed, using progression-free survival (PFS) as the primary endpoint and overall survival (OS) representing the secondary endpoint. Adverse events… More >

Abstract Aims: The study aimed to evaluate the effectiveness and adverse events of tyrosine kinase inhibitors (TKIs) in the first-line treatment of advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. Methods: A retrospective study on advanced NSCLC patients with EGFR mutations treated with TKIs as a first-line therapy at Nghe An Oncology Hospital, Vietnam between January 2017 and August 2023. The primary endpoints included objective response rate, progression-free survival, and tolerability. The secondary endpoint was overall survival. Results: A total of 211 patients received first-line treatment with Erlotinib (n = 74), Gefitinib (n… More >

Abstract Background: Non-small cell lung cancer (NSCLC) involves complex alterations in the epidermal growth factor receptor (EGFR) signaling pathway. This study aims to integrate multimodal omics analyses to evaluate and enhance EGFR-targeted therapies. Methods: We reviewed and synthesized omics data—including genomics, transcriptomics, proteomics, epigenomics, and metabolomics data—related to the EGFR pathway in NSCLC, examined the clinical outcomes of current therapies and proposed new treatment strategies. Results: Integrated omics analyses revealed the multifaceted role of EGFR in NSCLC. Transcriptomic analysis revealed gene expression alterations due to EGFR mutations, with upregulation of oncogenes and downregulation of tumor suppressors. Proteomics More >

Abstract Objectives: Glioblastoma (GB) is a grade IV glial tumor characterized by high malignancy and dismal prognosis, primarily due to high recurrence rates and therapeutic resistance. The epidermal growth factor receptor (EGFR), a receptor tyrosine kinase (RTK), regulates signaling pathways, including cell growth, proliferation, survival, migration, and cell death. Many cancers utilize immune checkpoints (ICs) to attenuate immune responses. CD73 is an enzyme that functions as an IC by hydrolyzing AMP to adenosine, suppressing immune cells in the tumor microenvironment. However, the role of CD73 in resistance to EGFR inhibitors is poorly understood. This study aims… More >

Abstract Background: Non-small cell lung cancer (NSCLC) is often accompanied by brain metastasis (BM), and the prognosis of patients with BM is poor. This study assesses the prognostic impact of BM in NSCLC patients with epidermal growth factor receptor (EGFR) mutations. Methods: We retrospectively evaluated 692 advanced NSCLC patients with EGFR mutations treated with tyrosine kinase inhibitors (TKIs) at West China Hospital from 2015 to 2019. The overall survival rate (OS), progression-free survival rate (PFS), objective response rate (ORR), disease control rate (DCR), and clinical parameters of the BM and non-BM groups were compared.

Abstract The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein that plays a crucial role in signal transduction and cellular responses. This review explores the function of EGFR in kidney physiology and its implications for various kidney diseases. EGFR signaling is essential for kidney function and repair mechanisms, and its dysregulation significantly impacts both acute and chronic kidney conditions. The review discusses the normal distribution of EGFR in kidney tubular segments, the mechanism of its activation and inhibition, and the therapeutic potential of EGFR-targeting antagonists and ligands. Additionally, it explores the pathophysiological characteristics observed More >

Abstract Background: Drug resistance is the main factor contributing to cancer recurrence and poor prognosis. Exploration of drug resistance-related mechanisms and effective therapeutic targets are the aim of molecular targeted therapy. In our study, the role of long non-coding RNA (lncRNA) AFAP1-AS1 in gemcitabine resistance and related mechanisms were explored in cervical cancer cells. Methods: Gemcitabine-resistant cervical cancer cell lines HT-3-Gem and SW756-Gem were constructed using the gemcitabine concentration gradient method. The overall survival rates and recurrence-free survival rates were evaluated by Kaplan-Meier analysis. The interaction was verified through a Dual-luciferase reporter gene assay and a… More > Graphic Abstract
