Background: Basal differentiation in oral squamous cell carcinoma is usually detected at invasive sites. However, its significance as a prognostic value has been poorly investigated.
Methods: COL17 was selected as a basal differentiation marker because of its stable expression in the basal-like cells of oral squamous cell carcinoma. Sixty-five cases of oral squamous cell carcinoma were subclassified into COL17-high (30 cases) and -low (35 cases) types, and the prognostic value was analyzed by Cox regression analysis. In addition, the stem cell markers such as SOX2, KLF4, MYC as well as the stem cell-related markers BMI1, EZH2, and YAP and its paralog TAZ, were immunohistochemically analyzed. Their prognostic values were investigated along with their COL17 status by Cox regression analysis.
Results: No significant difference was observed between the COL17-high and -low groups in the disease-specific survival and recurrence-free survival in oral squamous cell carcinoma. When the COL17-high and -low categories were combined with the SOX2, KLF4, EZH2, or YAP/TAZ status in the basal layers, together with gender and age as covariates, the hazard ratios reached 3.3, 3.7, 2.8, and 3.1, respectively. In addition, multivariate analysis, including COL17, SOX2, and KLF4, with gender and age as covariates, showed a significantly poor prognosis for disease-specific survival.
Conclusion: Based on the relatively high hazard ratios, it is indicated that basal differentiation and the expression status of SOX2 and KLF4 in the basal layers are prognostic factors for oral squamous cell carcinoma.

Introduction Oral verrucous carcinoma (OVC), a low-grade variation of oral squamous cell carcinoma (OSCC), is distinguished by endophytic development and a pebbly, mammillated surface. OVC, often referred to as Ackerman's tumor, has been known to involve lymph nodes but rarely spreads to regional and distant locations; when the primary tumor grows, it frequently involves surrounding tissues. Histopathologically, it has a thicker basement membrane, many reduplications, and a large area of inflammatory infiltration that resembles OSCC.

Introduction: The present study aims to observe the efficacy of submandibular gland excision vs. preservation during supraomohyoid neck dissection (SOHND) based on the postoperative outcomes for early oral squamous cell carcinoma (OSCC) with clinically N0 neck and xerostomia.
Materials And Methods: A pilot study was conducted to observe the efficacy of preservation vs.

The low expression of period circadian regulator 3 (PER3) in head and neck squamous cell carcinoma is closely correlated with tumor size and invasion depth. Hypoxia-inducible factor 1 subunit alpha (HIF-1α) regulates epithelial-mesenchymal transition (EMT) transcription factors, activates EMT, and promotes tumor metastasis. Here, we investigated the role and molecular mechanism of PER3 in regulating HIF-1α and metastasis in oral squamous cell carcinoma (OSCC) by using bioinformatics analyses and in vitro and in vivo experiments.

Objective: The study aims to identify potential pharmacophore models for targeting beta-catenin, a crucial protein involved in the development of oral squamous cell carcinoma (OSCC), using a combination of herbal compounds and computational approaches.
Methods: Five natural compounds namely Quercetin, Lycopene, Ovatodiolide, Karsil, and Delphinidin were selected based on their reported activity against beta-catenin. Ligand characteristics were analyzed using SwissADME to evaluate drug-likeness, lipophilicity (logP), and bioavailability.

Introduction: Squamous cell carcinoma (SCC) is the most common malignancy of the head and neck region. Combination therapy potentially enhances the effectiveness beyond that of each treatment alone. This study aimed to assess whether photodynamic therapy (PDT), using methylene blue as a photosensitizer in conjunction with doxorubicin, produces synergistic effects on the apoptosis of the oral squamous cell carcinoma (OSCC) cell line.
