This research intended to explore the expression levels of S100A9 protein in oral squamous cell carcinoma (OSCC), and to analyze its relation with clinicopathologic features in OSCC, then discuss its clinical significance in diagnosis and prognosis of OSCC. Using immunohistochemistry and Western blot to examine S100A9 in 35 oral squamous cell carcinoma specimen and 30 normal oral tissue as control.Expression of S100A9 in oral squamous cell carcinoma (77.1%) was obviously higher than that in normal organizations (46.7%, < 0.05 ). Among it, expression of low differentiated group was higher than that of high differentiated group. Expression of oral squamous cell carcinoma group in Ⅲ-Ⅳ period was higher than that of Ⅰ-Ⅱ period. The above differences were statistically significant. Expression of S100A9 was not associated with patients'age and gender (> 0.05). The difference had no statistical significance.Overexpression of S100A9 protein may play a vital role in the progression of OSCC, which can be served as a positive marker for the diagnosis and prognosis of OSCC.

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most common types of cancer worldwide and immune checkpoint inhibitors have shown favorable therapeutic effects in recurrent or metastatic or locally advanced head and neck squamous cell carcinoma (R/M/LA HNSCC). However, the effects of immunotherapy in HNSCC are still inconsistent because of complicating factors. This meta-analysis tries to provide a more precise assessment of the efficacy and safety of this integrated approach in HNSCC.

Background: We here investigated the value of imaging examination in evaluating tumor remission-based surgery in patients with head and neck squamous cell carcinoma (HNSCC), who had undergone neoadjuvant immunotherapy combined with chemotherapy (NICC).
Methods: HNSCC patients who underwent NICC and surgery from May 2021 to September 2023 were retrospectively analyzed. All patients had to undergo imaging examination evaluation, including enhanced computed tomography (CT) and enhanced magnetic resonance (MR) imaging before and after NICC.

The role of cancer stem cells (CSC) in oral cancer is widely accepted. Yet, the existence of CSC in dysplastic tissue and the molecular pathways of progression from dysplasia to malignancy remain to be explored. Our retrospective study aimed to analyze the presence of CSC in oral epithelial dysplasia and oral squamous cell carcinoma (OSCC) concerning two epithelial-mesenchymal transition markers: Snail and E-cadherin.

Background: Interaction between mesenchymal stem cells (MSCs) and oral squamous cell carcinoma (OSCC) cells plays a major role in OSCC progression. However, little is known about adipogenic differentiation alteration in OSCC-derived MSCs (OSCC-MSCs) and how these alterations affect OSCC growth.
Methods: MSCs were successfully isolated and cultured from normal gingival tissue, OSCC peritumoral tissue, and OSCC tissue.

Background: T cells are involved in every stage of tumor development and significantly influence the tumor microenvironment (TME). Our objective was to assess T-cell marker gene expression profiles, develop a predictive risk model for human papilloma virus (HPV)-negative oral squamous cell carcinoma (OSCC) utilizing these genes, and examine the correlation between the risk score and the immunotherapy response.
Methods: We acquired scRNA-seq data for HPV-negative OSCC from the GEO datasets.
