Motivation: Breast cancer (BC), with its rising prevalence and mortality rate, is one of the most significant human health issues. The family of transmembrane tyrosine kinases that promote neuronal growth includes the neurotrophic tyrosine kinase receptors (NTRKs). NTRK1-3 genes encode the members of this family. Alterations of NTRK genes can induce carcinogenesis both in neurogenic and non-neurogenic cells. The prevalence of NTRK gene fusion is under 1% in solid tumours but is highly encountered in rare tumours. Since the prognostic values of NTRK families' expression in various types of cancer are becoming increasingly evident, we aimed to conduct a comprehensive bioinformatics study evaluating the prognostic significance of the NTRK family in BC. Online bioinformatic databases including TCGA, UALCAN, Kaplan-Meier plotter, bc-GenExMiner, cBioPortal, STRING, Enrichr, and TIMER were utilized for analysis.
Results: High levels of NTRK2 and 3 demonstrated better associations with overall survival (OS) and recurrence-free survival (RFS) in BC patients ( < .05), while high levels of NTRK1 showed an applicable correlation with RFS in BC patients ( < .001). Our findings provide a new outlook that might aid in the field of personalized medicine and therapeutic use of NTRK as a prognostic biomarker in BC.

Arid4a Suppresses Breast Tumor Metastasis by Enhancing MTSS1 Expression via mRNA Stability.
Cancer Med
March 2025
Institute of Microcirculation, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Background: Tumor metastasis is one of the main causes of death in cancer patients; however, the mechanism controlling metastasis is unclear. The posttranscriptional regulation of metastasis-related genes mediated by AT-rich interactive domain-containing protein 4A (Arid4a), an RNA-binding protein (RBP), has not been elucidated.
Methods: Bioinformatic analysis, qRT-PCR, immunohistochemistry, and immunoblotting were employed to determine the expression of Arid4a in breast tumor tissues and its association with the survival of cancer patients.
Influence of gut microbial metabolites on tumor immunotherapy: mechanisms and potential natural products.

In recent years, tumor immunotherapy has made significant breakthroughs in the treatment of malignant tumors. However, individual differences in efficacy have been observed in clinical practice. There is increasing evidence that gut microbial metabolites influence the efficacy of distal tumor immunotherapy via the gut-liver axis, the gut-brain axis and the gut-breast axis, a process that may involve modulating the expression of immune cells and cytokines in the tumor microenvironment (TME).

High tumour mutational burden (TMB-high), identified through comprehensive genomic profiling (CGP), is a biomarker that predicts the efficacy of immune checkpoint inhibitors. CGP testing is recommended for rare cancers with limited effective treatment options. Here, we provide the first report of a malignant phyllodes tumour of the breast demonstrating TMB-high status and effective treatment with pembrolizumab.

Article Synopsis
- Advances in breast cancer treatment have not significantly improved outcomes for metastatic cases, which still lead to high mortality rates.
- Physical activity has been linked to reduced breast cancer risk and improved treatment outcomes, prompting a study on its effects on metastatic triple negative breast cancer (TNBC).
- Results show that increasing physical activity after surgical interventions can significantly enhance metastasis-free survival in mice, suggesting exercise may play a crucial role in delaying cancer progression.
Expression of Proliferating Cell Nuclear Antigen (PCNA) in Nasal Polyp: A Systematic Review and Meta-analysis.
Indian J Otolaryngol Head Neck Surg

Department of Pathology, Faculty of Medicine, Shahed University, Tehran, Iran.
Unlabelled: Nasal polyp (NP) is a pathological benign mass that affects the nasal cavity and paranasal sinuses. This lesion is occasionally associated with chronic rhinosinusitis (CRS), which is named chronic rhinosinusitis with nasal polyps (CRSwNP). Proliferating cell nuclear antigen (PCNA) indicates abnormal cell proliferation which may help assess the nasopharyngeal lesions and upper airway cancers.
