AI Article Synopsis

  • Angiogenesis, regulated by vascular endothelial growth factor (VEGF), plays a significant role in cancer progression, yet anti-VEGF therapies have had limited success.
  • Two specific VEGFA single nucleotide polymorphisms (SNPs), rs833068GA and rs25648CC, were found to be linked to angiogenesis markers and influenced breast cancer-specific survival, particularly in estrogen receptor (ER)-negative cases.
  • Additional associations were observed between the rs699947CA and rs3025039CC genotypes and tumor characteristics, indicating that certain VEGF SNPs may have implications for patient outcomes that warrant further investigation.

Article Abstract

Angiogenesis is recognized as a hallmark of cancer, and vascular endothelial growth factor (VEGF) is a key regulator of the angiogenic process and is related to cancer progression. Anti-VEGF therapy has been tried but with limited success and without useful stratification for angiogenesis markers. Further, the landscape of VEGF single nucleotide polymorphisms (SNPs) in breast cancer and their clinical relevance is not well studied, and their relation to tissue-based angiogenesis markers has not been explored. Here, we studied a selection of VEGFA SNPs in nontumor lymph nodes from a population-based breast cancer cohort (n = 544), and their relation to clinicopathologic variables, vascular tissue metrics, and breast cancer-specific survival. Two of the SNP candidates (rs833068GA genotype and rs25648CC genotype) showed associations with angiogenesis tissue markers, and the VEGFA rs833068GA genotype was associated with breast cancer-specific survival among ER-negative cases. We also found trends of association between the rs699947CA genotype and large tumor diameter and ER-negative tumors, and between the rs3025039CC genotype and large tumor diameter. Our findings indicate some associations between certain VEGF SNPs, in particular the rs833068GA genotype, and both vascular metrics and patient survival. These findings and their potential implications need to be validated by independent studies.

Breast cancer remains the leading cause of mortality among women with cancer. This article delves into the intricate relationship between breast cancer and cancer stem cells (CSCs), emphasizing advanced methods for their identification and isolation. The key isolation techniques, such as the mammosphere formation assay, surface marker identification, Side Population assay, and Aldehyde Dehydrogenase assay, are critically examined.

Epidermal growth factor receptor (EGFR) plays an important role in the regulation of cell proliferation and migration [1]. It forms a homodimer or heterodimer with other ErbB receptor family members to activate downstream signaling. Emerging evidence indicates that the EGFR activity and downstream signaling are regulated by other proteins except its family members during tumorigenesis.

Purpose: Perfusion modeling presents significant opportunities for imaging biomarker development in breast cancer but has historically been held back by the need for data beyond the clinical standard of care (SoC) and uncertainty in the interpretability of results. We aimed to design a perfusion model applicable to breast cancer SoC dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) series with results stable to low temporal resolution imaging, comparable with published results using full-resolution DCE-MRI, and correlative with orthogonal imaging modalities indicative of biophysical markers.

Methods: Subsampled high-temporal-resolution DCE-MRI series were run through our perfusion model and resulting fits were compared for consistency.

Background: We aimed to investigate the clinical and molecular characteristics of different degrees of human epidermal growth factor receptor 2 (HER2) protein expression in HER2-negative breast cancer and the related factors affecting the efficacy of neoadjuvant chemotherapy in HER2-low breast cancer patients.

Methods: The study endpoint was pathological complete remission (PCR). Blood specimens and fresh cancer tissue samples were collected before neoadjuvant chemotherapy for whole-exon sequencing (WES) and RNA sequencing (RNA-seq), and patients were divided into a human epidermal growth factor receptor 2 (HER2)-low group and a HER2-0 group according to their HER2 expression status via bioinformatics analysis.

This study aimed to evaluate the efficacy of pyrotinib, an orally administered small molecule tyrosine kinase inhibitor, combined with neoadjuvant chemotherapy in treating patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Pyrotinib works by inhibiting the HER2 signaling pathway, thereby preventing tumor cell growth. This single-arm clinical trial aimed to assess the total pathological complete response (tpCR; ypT0/is and ypN0) rate as the primary endpoint.
