  • Metastatic urothelial carcinoma (mUC) has a poor prognosis, and the study focuses on Prostaglandin Reductase 1 (PTGR1), which is crucial for the effectiveness of acylfulven drugs for treating specific mUC patients with ERCC2 mutations.
  • The study evaluated PTGR1 expression in untreated mUC patients using immunohistochemistry (IHC), RNA expression analysis, and targeted genomic panels to identify candidates for clinical trials and assess the potential of PTGR1 as a prognostic biomarker.
  • Results indicated that 40% of tumors tested positive for PTGR1 via IHC, demonstrating high sensitivity and specificity in RNA expression analysis, which correlated with tumor mutations and overall

Objective: Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin lymphoma with the sporadic subtype being predominant in North America. The clinical presentations and outcomes of pediatric BL within the head and neck were assessed using both an institutional case series and the Surveillance, Epidemiology, and End Results (SEER) Cancer database.

Methods: The electronic medical record at our quaternary children's hospital was queried over a 22-year period (2000-2022) for BL patients with head and neck manifestations.

Department of Otorhinolaryngology, Head and Neck Surgery and Audiology, Copenhagen University Hospital - Rigshospitalet, 2100 Copenhagen, Denmark; Institute of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, 2200 Copenhagen, Denmark; Copenhagen Academy for Medical Education and Simulation (CAMES), 2100 Copenhagen, Denmark.

Background: Squamous cell carcinomas of unknown primary (SCCUP) are often Human Papillomavirus (HPV)-positive. Due to their small size, extensive surgical workup is required to locate the primary tumors. High-frequency transoral ultrasound (US) may provide improved visualization of these small tumors.

  • * The study analyzed T cell exhaustion in DLBCL using single-cell transcriptome data, revealing a higher proportion of exhausted T cells in DLBCL compared to normal tonsil tissue, with unique gene expression patterns related to immune regulation and metabolic processes.
  • * Key findings included the upregulation of the ID3 gene in exhausted T cells, contributing to their dysfunction, and the identification of important protein interactions and signaling pathways, which could lead to new

Background: Herein, we evaluated the attributable fraction (AF) of human papillomavirus (HPV)-mediated (HPV+) oropharyngeal carcinomas (OPCs) in Greece over a recent calendar period.

Patients And Methods: ORPHEAS, a retrospective, observational, multicenter, cross-sectional study with prospective recruitment, included adult patients with OPC in 2017-2022, each of them with a high-quality, treatment-naïve tumor specimen. The primary endpoint was the HPV-AF, defined as combined positivity for p16 (p16) overexpression and HPV DNA presence by central laboratory testing, among included patients.

Introduction: Strategies for treatment of tonsil carcinoma are under active investigation. Limiting surgical and radiation treatment volumes to the primary tumor and ipsilateral neck in appropriately selected patients are one such approach. Here, we present our institutional experience with treatment through ipsilateral surgical or radiotherapeutic neck management.

  • Schlafen 11 (SLFN11) is a helicase that regulates how cells respond to stress during DNA replication, and its expression can predict treatment outcomes in cancer patients receiving certain therapies.
  • In a study involving 6,658 tumors, SLFN11 was found to be rare in common epithelial tumors (e.g., breast and prostate cancers) but prevalent in several more aggressive tumors and specific mesenchymal and neuroectodermal cancers.
  • The absence of SLFN11 may lead to worse outcomes for patients treated with DNA-damaging drugs, suggesting the need for alternative treatments for those cancers that lack this biomarker.

Cavernous malformations surrounding the fourth ventricle are challenging lesions to access and treat surgically owing to the complexity and eloquence of adjacent neural tissue [1] Long-standing practice included tissue transgression through the overlying cerebellar cortical surface of the hemisphere or vermis [1-3]. Using natural corridors such as tonsillobiventral fissure, cerebellomedullary fissure, and tonsillouvular fissure (TUF) offers elegant access to the fourth ventricle, avoiding traversing of neural tissue [4-7]. A 32-year-old male presented with headache, nausea, vomiting, double vision, and vertigo.

Introduction: The human leukocyte antigen complex (HLA) is essential for inducing specific immune responses to cancer by presenting tumor-associated peptides (TAP) to T cells. Overexpressed tumor associated antigens, mainly cancer-testis antigens (CTA), are outlined as essential targets for immunotherapy in oropharyngeal squamous cell carcinoma (OPSCC). This study assessed the degree to which presentation, gene expression, and antibody response (AR) of TAP, mainly CTA, are correlated in OPSCC patients to evaluate their potential as immunotherapy targets.

Article Synopsis
  • The study aimed to evaluate the significance of high-risk HPV testing in patients with unknown primary carcinoma but secondary metastasis to the neck, focusing on those who underwent surgical procedures for identification of the primary site.
  • Conducted at a tertiary care center over one year, the study included patients with proven squamous cell carcinoma in the neck and involved various surgical and testing methods, including tonsillectomy and HPV RNA/DNA analysis.
  • Results showed very low positivity rates for p16 (5.56% in tonsils, 0% in tongue, 2.78% in lymph nodes) and undetectable HPV DNA in tissues and blood, suggesting that detailed high-risk HPV analysis may not be crucial in this specific patient population
