Distinct immunological features of oropharyngeal cancer peritumoral tonsillar tissues from inflammatory tonsils and regional lymph nodes: A pilot study.
PLoS One
January 2025
Division of Otorhinolaryngology and Head and Neck Surgery, Graduate School of Medical Science, Kanazawa University, Kanazawa, Ishikawa, Japan.
Background: Cancer immune responses are generated in secondary lymphoid organs, such as the lymph nodes and tonsils. In the current study, transcriptional profiles of peritumoral tonsillar tissues (PTTs) from oropharyngeal cancers (OPCs) were assessed and compared with those of inflammatory tonsils and regional lymph nodes (rLNs).
Methods: RNA samples of PTTs and rLNs from 13 OPCs, and 4 inflammatory tonsils were subjected to microarray analysis, and differentially expressed genes (DEGs) identified from 730 nCounter Panel immune-related genes.
Potentialities and critical issues of liquid biopsy in clinical practice: An umbrella review.
Transl Oncol
January 2025
Department of Health Promotion, Mother and Child Care, Internal Medicine and Medical Specialties, University of Palermo, Palermo, Italy; Division of Biostatistics & Epidemiology Research, Cincinnati Children's Hospital Medical Center, University of Cincinnati College of Medicine, United States.
Background: Liquid biopsy (LB) is a laboratory test performed on a fluid sample aiming at analyzing molecular data derived from circulating cells and related entities, or from nucleic acids. This umbrella review aims to map and evaluate the evidence supporting the use of LB in medicine across different medical specialities and conditions.
Methods: We searched three repositories from database inception up to October 1, 2023 and we included meta-analyses of observational studies reporting data on the use of LB, compared to gold standard, and its accuracy (area under the curve, AUC).
Functional soft palate reconstruction.
JPRAS Open
March 2025
Department of Plastic, Reconstructive, Aesthetic, and Hand Surgery, University Hospital Basel, Basel, Switzerland.
Background: The excision of oropharyngeal carcinoma of more than 50% of the soft palate followed by static reconstruction may result in functional deficits, including velopharyngeal insufficiency, swallowing, and speech difficulties. We describe a functional soft palate reconstruction technique aimed at restoring aeromechanical and acoustic functions, enabling swallowing without nasal regurgitation and speech with low nasalance.
Material And Methods: We developed a new operative technique, using muscle transfer and a free flap to create a dynamic reconstruction.
National and subnational plans for primary prevention and early detection of oral and oropharyngeal cancer: a scoping review.
Cad Saude Publica
January 2025
Faculdade de Odontologia, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brasil.
This scoping review maps primary prevention and early detection strategies for oral and oropharyngeal cancer across national cancer plans and noncommunicable disease plans from all World Health Organization Member States. Following PRISMA-ScR guidelines, bibliographic search was performed on key organization websites until March 2023. Of the 194 countries assessed three had subnational plans, resulting in 264 self-governing political entities and similar with revised plans.

This study aimed to evaluate the dosimetric and clinical outcomes of flattening filter (FF) versus flattening filter-free (FFF) beams in head and neck cancer (HNC) patients treated with volumetric modulated arc therapy (VMAT). Twenty-four patients with 70/59.4/54 Gy dose prescribed in 33 fractions with simultaneous integrated boost treatment were retrospectively analyzed to compare treatment delivery efficiency, target coverage, sparing of organs at risk (OARs), and remaining volume at risk (RVR) in two HNC groups (nasopharyngeal and oropharyngeal).
