Laryngeal squamous cell carcinoma (LSCC) demonstrates increased rates due to pathogenetic factors including tobacco, chronic alcohol consumption and also viral-mediated deregulation. During carcinogenetic process, laryngeal epithelia accumulate gross chromosome and specific gene aberrations. Oncogenes’ overactivation is a crucial genetic event in malignant and pre-malignant neoplastic epithelia. Among oncogenes, C-myc (gene locus: 8q24.12-q24.13) acts as a strong transcription factor, implicated in the control of cell differentiation and apoptosis. Upregulation of the gene - due to increased copy numbers (amplification) - seems to be correlated with aggressive biological behaviour in LSCCs. In the current special molecular article we explored the role of C-myc deregulation in LSCC.

Background: Lymph node ratio (LNR), log odds of positive lymph nodes (LODDS), and the number of postoperative lymph node staging (pN) are prognostic indicators of various cancers. However, the prognostic values of these indicators remain unclear in hypopharyngeal squamous cell carcinoma (HPSCC). This study's primary objective was to investigate the predictive value of LNR, LODDS, and pN for advanced HPSCC, and the secondary objective was to compare which of the values had the best predictive value for advanced HPSCC.

Understanding the impact of senescence on disease is limited by the lack of tools to lineage label senescent cells. In a recent Cell issue, Zhao et al. create mouse models to genetically manipulate and trace p16 cells, identifying contrasting roles for senescent macrophages and endothelial cells (ECs) in liver fibrosis.

Addition of epithelial progenitor cells drives progressive extension of the heart tube during cardiac morphogenesis. In this issue of Developmental Cell, Arriagada et al. (2024) refine our understanding of how these cells condition and interact with the underlying extracellular matrix, demonstrating that autonomous fibronectin synthesis controls their apicobasal polarity and deployment to the heart.

Introduction: Head and neck squamous cell carcinoma (HNSCC) is the seventh most common type of cancer in the world. Metastases occur in up to 40 % of cases and bones are the second most frequent site. Metastases in extremities are uncommon with very few publications covering distal lower-limb bone metastasis.
