Summary: Angiogenesis is the formation of new blood vessels from existing ones. Abnormal angiogenesis, seen in tumor microenvironments, is characterized by distorted and leaky blood vessels with various shapes and high perfusion efficiency. Tumor angiogenesis plays a crucial role in cancer growth, invasion, and metastasis, and is tightly regulated by signaling networks. Targeting multiple signaling pathways involved in angiogenesis is important for effective antiangiogenic therapy. New therapeutic approaches, such as blocking specific proteins or genes, are being explored to dissect alternative angiogenesis mechanisms in tumor microenvironments.

Summary: High expression levels of alpha-SMA and hypoxia markers are associated with poor prognosis in pancreatic cancer patients. Mechanistically, hypoxia induces HGF expression and secretion in PSC via HIF-1 alpha, which then activates Met and suppresses pancreatic cancer cell sensitivity to EGFR inhibitors. The combination of EGFR inhibitor and Met inhibitor shows promise for pancreatic cancer treatment based on the demonstrated signaling axis between PSC and cancer cells.

Summary: EREG activates EGFR signaling pathways to promote cancer progression and is associated with specific types of tumors and drug resistance. Tailored therapy should be chosen based on different oncogenic mutations and cellular contexts, such as combination treatment targeting EREG/EGFR and other driver mutations.

Summary: The most frequently altered gene in glioblastoma (GBM) is the epidermal growth factor receptor (EGFR), which plays a crucial role in tumor development and anti-tumor immune response. While current molecular targeted therapies against the EGFR signaling pathway and its downstream key molecules have not shown positive clinical outcomes in GBM. However, immunotherapies, especially immune checkpoint inhibitors, have demonstrated effective anti-tumor responses in various cancers. Yet, the clinical efficacy is limited in GBM patients with EGFR alterations, implying a potential involvement of EGFR signaling in tumor immune response. Recent studies suggest that EGFR alterations not only promote GBM cell proliferation but also affect immune components in the tumor microenvironment, leading to the recruitment of immunosuppressive cells and inhibition of T and NK cell activation. Furthermore, EGFR alterations upregulate the expression of immune suppressive molecules or cytokines. This review aims to explore the role of EGFR alterations in establishing an immunosuppressive tumor microenvironment and hopes to provide a theoretical basis for combining targeted EGFR inhibitors with immunotherapy for GBM.

Summary: Colorectal cancer and other solid tumors in adults present challenges for successful treatment due to the tumor microenvironment hindering conventional therapies and suppressing immune activities. Genetic approaches have the potential to interfere with local immunosuppression, thereby facilitating immune responses against cancer. Bacterial phages provide a novel means of delivering targeted genetic interventions into tumors.

Summary: Chimeric antigen receptor (CAR)-T cells have limited efficacy in treating glioblastoma (GBM) and other solid tumors due to the immunosuppressive tumor microenvironment (TME). Previous studies have shown that blocking vascular endothelial growth factor (VEGF) signaling can improve tumor vessel normalization and enhance the delivery of CD8+ T cells for effective immunotherapy. In this study, the researchers tested the hypothesis that anti-VEGF therapy can improve the delivery and efficacy of CAR-T cells in mice with GBM tumors, and found that it indeed enhanced CAR-T cell infiltration, delayed tumor growth, and prolonged survival.

Summary: This study investigates the immune microenvironment of EGFR-mutant and EGFR wild-type lung adenocarcinomas (LUADs) using single-cell transcriptome sequencing and multiplex immunohistochemistry. The results show that EGFR-mutant LUAD lacks CD8(+) tissue-resident memory (TRM) cells and has less crosstalk between T cells and other cell types compared to EGFR wild-type LUAD. These findings contribute to a better understanding of the immune landscape of EGFR-mutant LUAD at the single-cell level and suggest that the lack of CD8(+) TRM cells may be a key factor in the suppressive TME of EGFR-mutant LUAD.

Summary: Although ICIs have significantly changed the treatment paradigm in advanced NSCLC, their clinical benefits are limited in patients with EGFR-mutated tumors due to the unique characteristics of the tumor microenvironment. The cancer immunogram can visualize the state of cancer-immune system interactions in EGFR-mutated NSCLC, helping identify subpopulations that may benefit from ICI treatment. Future strategies need to be developed to maximize the efficacy of ICI treatment in patients with EGFR-mutated NSCLC in the era of combination immunotherapies.

Summary: This study found that lung adenocarcinomas (LUAD) with EGFR-positive and ALK-positive had a suppressive tumor immune microenvironment (TIME) and were less responsive to immunotherapy. The TIME in patients with EGFR/ALK-positive LUAD brain metastases (BMs) was different from that in primary lung cancer. Evaluating the immune characteristics of LUAD BMs is important for clinical treatment.

Summary: The tumor microenvironment plays a role in tumorigenesis and drug resistance through the overexpression of insulin-like growth factor 1 (IGF-1). Anti-IGF therapies have shown potential in inhibiting cancer and overcoming chemotherapy drug resistance in preclinical studies, but toxicity and resistance are challenges in clinical trials.

Summary: The article evaluated the prognostic effect and clinical significance of epidermal growth factor receptor and its phosphorylated form (EGFR/p-EGFR) in nasopharyngeal carcinoma through a systematic review and meta-analysis. The results showed that EGFR overexpression could be used as a biomarker for poor overall survival (OS) and disease-free survival (DFS) in nasopharyngeal carcinoma, but not for progression-free survival (PFS) and distant metastasis-free survival (DMFS). The overexpression of p-EGFR was not associated with the prognosis of nasopharyngeal carcinoma patients.
