The effect of body mass index at diagnosis on survival of patients with squamous cell head and neck carcinoma.

The aim of this study is to investigate the prognostic role of body mass index (BMI) on survival from head and neck cancer (HNC). We performed a pooled analysis of studies included in the International Head and Neck Cancer Epidemiology consortium. We used Cox proportional hazards models to estimate the adjusted hazard ratios (HR) for overall survival and HNC-specific survival, and we stratified the results according to cancer site.

Cross-ancestral GWAS identifies 29 novel variants across Head and Neck Cancer subsites.

In this multi-ancestry genome-wide association study (GWAS) and fine mapping study of head and neck squamous cell carcinoma (HNSCC) subsites, we analysed 19,073 cases and 38,857 controls and identified 29 independent novel loci. We provide robust evidence that a 3' UTR variant in (rs78378222, T>G) confers a 40% reduction in odds of developing overall HNSCC. We further examine the gene-environment relationship of and variants demonstrating their effects act through both smoking and alcohol use.

Anxiety, depression, and fear of cancer recurrence in head and neck cancer.

Objective: Patients with head and neck cancer (HNC) report some of the highest levels of psychological distress amid managing their disease as well as debilitating and disfiguring treatment side effects. Fear of cancer recurrence (FCR) is a top unmet need and concern of patients with HNC. Prior research suggests elevated symptoms of anxiety and depression are potential antecedents to FCR, but findings have been limited in HNC populations.

Macroscopy of specimens from the head and neck.

Macroscopic examination of surgical resections from the head and neck may be difficult due to the complex anatomy of this area. Recognition of normal anatomical structures is essential for accurate assessment of the extent of a disease process. Communication with the surgical team, correct specimen orientation and sampling are critical for assessment and the importance of radiological and clinical correlation is emphasised.

Macroscopic examination of pathology specimens: a critical reappraisal.

Meticulous macroscopic examination of specimens and tissue sampling are crucial for accurate histopathology reporting. However, macroscopy has generally received less attention than microscopy and may be delegated to relatively inexperienced practitioners with limited guidance and supervision. This introductory paper in the minisymposium, , focuses on issues regarding macroscopic examination and tissue sampling that have been insufficiently addressed in the published literature.
