The aim was to evaluate sentinel node detection capacity by means of a magnetic probe in 11 patients with oral squamous cell carcinoma at stages T1-T2 received submucosal injections of a superparamagnetic iron oxide contrast agent (SPIO). A magnetic probe was used for sentinel node biopsy. The use of SPIO and magnetic probes in the early stages of oral cancer may offer an alternative to conventional radioisotope techniques and/or elective neck dissection.

Considering the increasing use of immune checkpoint inhibitors in cancer treatment, our aim is to report a rare cutaneous immune-related adverse event induced by PD-1 inhibitor pembrolizumab and provide a brief overview of pembrolizumab-induced subacute cutaneous lupus erythematosus (SCLE) cases in the literature. We report a 67-year-old woman with oropharyngeal squamous cell carcinoma who developed SCLE during treatment with pembrolizumab. After 18 weeks (sixth cycle) of pembrolizumab immunotherapy, a widespread pruritic erythematous rash evaluated as grade 3 immune-related adverse event appeared primarily on the patient's limbs.

Background: This study aimed to investigate potential cellular senescence inhibitory genes (CSIGs) and discover novel therapeutic targets in head and neck squamous cell carcinoma.
Methods: Dysregulated CSIGs were identified based on The Cancer Genome Atlas (TCGA) and the Human Aging Genomic Resources (HAGR) database. Prognostic value and immune infiltration were assessed through bioinformatic analysis.

Background: The conventional treatment for locally advanced head and neck squamous cell carcinoma (LA-HNSCC) is surgery; however, the efficacy of definitive chemoradiotherapy (CRT) remains controversial.
Objective: This study aimed to evaluate the ability of deep learning (DL) models to identify patients with LA-HNSCC who can achieve organ preservation through definitive CRT and provide individualized adjuvant treatment recommendations for patients who are better suited for surgery.
Methods: Five models were developed for treatment recommendations.

Introduction The role of concomitant chemoradiation therapy (CTRT) or radiation therapy (RT) is not well defined in operated cases of oral squamous cell carcinoma (OSCC) with positive perineural spread. The purpose of the study was to determine whether the use of concurrent CTRT or RT would enhance the five-year disease-free survival of patients with positive perineural invasion (PNI). Materials and methods Data were analysed retrospectively from January 2014 to December 2023.
