Safety and reliability of the internal jugular vein for venous anastomoses in head and neck oncological reconstruction: A retrospective study.

This study aimed to assess the efficacy of utilizing the internal jugular vein (IJV) as the primary recipient site for venous anastomoses in head and neck oncological reconstruction. Patients who underwent a free flap reconstruction of the head and neck were retrospectively included. Venous anastomoses were preferentially performed less than 1 cm from the IJV, either end-to-side (EtS) on the IJV, or end-to-end (EtE) on the origin of the thyrolingofacial venous (TLF) trunk.

Fine needle aspiration as a diagnostic modality for Warthin tumors identified as fluorodeoxyglucose positron emission tomography/computed tomography-positive.

Limited evidence exists regarding the 2-deoxy-2-[fluorine-18]-fluoro-D-glucose (FDG) avidity of Warthin tumors, the second most common benign parotid gland tumor. This study aims to clarify this aspect by analyzing patients who underwent FDG positron emission tomography/computed tomography (PET/CT) and quantifying tumor standardized uptake values (SUV). Medical records of 29 patients with fine needle aspiration (FNA)-confirmed Warthin tumors who underwent FDG-PET/CT near the diagnosis of Warthin tumor were reviewed.

Manipulating feedback on schizophrenia: Evidence from a Posner task.

Individuals with schizophrenia show difficulties in achieving vital objectives. Abnormal behavioral and emotional responses to environmental feedback may be some of the psychological mechanisms underlying this lack of goal attainment in schizophrenia. The present study aims to assess how different types of feedback may affect performance in a computerized affective Posner task (non-monetary vs.

A Rare Cause of SCC Antigen Elevation: Inverted Sinonasal Papilloma.

We report the case of a 68-year-old woman who underwent 18F-FDG PET/CT for squamous cell carcinoma antigen (SCC Ag) elevation in the follow-up of a uterine cervical cancer. The examination showed an FDG-avid mass of the left nasal cavity with left maxillary sinusitis and no other site of abnormal FDG uptake. Surgical resection of the nasal polyp was performed, and pathological examination of the specimen revealed an inverted sinonasal papilloma.

Prognostic value of tumor mutational burden in patients with oral cavity squamous cell carcinoma treated with upfront surgery.

Background: Oral cavity is the most prevalent site of head and neck squamous cell carcinomas (HNSCCs). Most often diagnosed at a locally advanced stage, treatment is multimodal with surgery as the cornerstone. The aim of this study was to explore the molecular landscape of a homogenous cohort of oral cavity squamous cell carcinomas (OCSCCs), and to assess the prognostic value of tumor mutational burden (TMB), along with classical molecular and clinical parameters.

Prognostic value of intratumoral Fusobacterium nucleatum and association with immune-related gene expression in oral squamous cell carcinoma patients.

Changes in the oral microbiome, particularly Fusobacterium nucleatum, are associated with oral squamous cell carcinoma (OSCC). F. nucleatum has been reported to modulate local immunity in cancers.

Biomarkers of cetuximab resistance in patients with head and neck squamous cell carcinoma.

In patients with head and neck squamous cell carcinoma (HNSCC), cetuximab [a monoclonal antibody targeting epidermal growth factor receptor (EGFR)] has been shown to improve overall survival when combined with radiotherapy in the locally advanced setting or with chemotherapy in first-line recurrent and/or metastatic (R/M) setting, respectively. While biomarkers of resistance to cetuximab have been identified in metastatic colorectal cancer, no biomarkers of efficacy have been identified in HNSCC. Here, we aimed to identify biomarkers of cetuximab sensitivity/resistance in HNSCC.
