Article Abstract
Background: Circulating tumour DNA (ctDNA) has emerged as a valuable liquid biopsy biomarker in the field of oncology, including head and neck squamous cell carcinomas (HNSCCs), offering potential insights into cancer diagnosis, progression, and prognosis. This review aims to comprehensively evaluate the utility of ctDNA as a prognostic biomarker in HNSCC.
Methods: PubMed and Ovid were searched as part of our review. Studies that investigated the relationship between ctDNA and prognosis in HNSCC patients were included. Outcomes extracted included basic characteristics, ctDNA details and survival data. Meta-analysis was performed on eligible studies to determine pooled progression-free/recurrence-free survival (RFS/PFS) and overall survival (OS).
Results: Twenty-two studies were included, involving 5062 HNSCC patients from 11 countries. The meta-analysis demonstrated that the positive ctDNA/methylation detection was associated with worse OS (HR = 2.00, 95% CI 1.35-2.96) and worse PFS/RFS (HR = 3.54, 95% CI 1.05-11.85). Positive ctEBV DNA was associated with poorer OS (HR = 2.86, 95% CI 1.84-4.45) and poorer PFS/RFS (HR = 1.93, 95% CI 1.74-2.13). Positive ctHPV DNA was associated with poorer OS (HR = 1.38, 95% CI 1.07-1.38) but not PFS/PFS (HR = 1.33, 95% CI 0.96-1.85).
Conclusion: Meta-analysis indicates that the status of ctDNA is significantly associated with the prognosis of HNSCC patients, with ctDNA/methylation-negative patients demonstrating better PFS/RFS and OS.

Background: Head and neck squamous cell carcinoma (HNSCC) stands as a significant global health concern, marked by its substantial impact on both morbidity and mortality rates. Although previous studies have suggested that circular RNAs (circRNAs) may influence HNSCC progression, the underlying mechanisms remain largely unclear.
Methods: In this study, we first used quantitative real-time polymerase chain reaction (qRT-PCR) to measure the expression levels of circSHPRH in HNSCC tissues and cell lines.
Role of Radiomics to Predict Disease Recurrence in Sinonasal Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis.

Introduction: Radiomics offers the potential to predict oncological outcomes from pre-operative imaging, aiding in the identification of 'high risk' patients with sinonasal cancer who are at an increased risk of recurrence. This study aims to comprehensively review the current literature on the role of radiomics as a predictor of disease recurrence in sinonasal squamous cell carcinoma.
Methods: A systematic search was conducted in Medline, EMBASE and Web of Science databases.

Tumors frequently evade immune destruction by impairing cytotoxic CD8 T-cell responses, highlighting the need for strategies that restore T-cell functionality. Here, we identify SLAMF7 (CD319) as a key enhancer of human CD8 T-cell responses against tumors. SLAMF7 expression is induced by pro-inflammatory signals such as IL-12 and CD28 co-stimulation.

Head and neck squamous cell carcinoma (HNSCC) originates in the epithelial lining of the oral cavity, pharynx, and larynx, with over 830,000 new cases diagnosed globally in 2020, making it the seventh most prevalent cancer. Despite treatment advances, high-grade HNSCCs remain associated with poor outcomes and a high risk of recurrence. Although Cancer Stem Cells (CSCs) are rare in HNSCC tumors, they are key drivers of tumor relapses, as they evade apoptosis and survive current therapies through enhanced DNA repair and quiescence.
