Advanced-stage patients with frequent recurrences undergo treatments that significantly degrade their quality of life.

Does Changes in the Muscles Beneath the Submucosal Tissues Necessitate a Novel Strategy in the Medical Management of OSMF: A Systematic Review.

This study is envisioned to assess the structural changes the muscles undergo beneath the submucosal tissues and whether these changes necessitate a novel strategy from the existing conventional modality in the treatment of oral submucous fibrosis (OSMF) medically through a systematic literature survey. Literature search was performed electronically using Medline, EMBASE and CENTRAL databases to identify published literature until the end of April 2024 in dental, oral and maxillofacial surgery, plastic surgery and otolaryngology journals containing the terms "oral submucous fibrosis", "muscles of mastication", "muscles of facial expression", "histopathologic study", "ultrasonographic study", "CT", "MRI" in either their titles, abstracts, and keywords with only English being the preferred language. The data was extracted from the selected articles and prudently studied to gather and compile the data.

Quantitative proteogenomic characterization in MUC1 and MUC4 in oral squamous cell carcinoma, oral potentially malignant disorders, and normal oral mucosa in carcinogenesis.

Introduction: Mucins are glycoproteins with a significant molecular weight that have a diverse range of biological functions. MUC1 & MUC4 are transmembrane mucin family members that are expressed in airway epithelial cells and body fluids. It is expressed excessively in numerous carcinomas in addition to their altered expression.

Diagnostic potential of salivary IL-1β, IL-8, SAT, S100P, and OAZ1 in oral squamous cell carcinoma, oral submucous fibrosis, and oral lichen planus based on findings from a Sri Lankan cohort.

The research examined the salivary concentrations of various biomarkers, such as OAZ1, SAT, S100P, IL-1β, and IL-8 aiming to detect early-stage oral squamous cell carcinoma (OSCC). These biomarkers show potential as indicators for detecting both pre-cancerous and cancerous states within the oral cavity. Analyzing these specific molecules in saliva could help clinicians enhance diagnostic accuracy and refine early detection methods for OSCC.

Myofibroblasts persist through immune privilege mechanisms to mediate oral submucous fibrosis: Uncovering the pathogenesis.

Immune privilege is the ability to tolerate foreign antigens without eliciting an inflammatory immune response. Several mechanisms explain a structure's immune privilege status, which is regulated by innate and adaptive immune responses. The role of myofibroblasts in perpetuating fibrosis by acquiring an immune privileged phenotype against the backdrop of oral submucous fibrosis (OSF) is evolving.

Emerging functions of lycopene in the management of digestive premalignant lesions.

Common digestive precancerous lesions, including oral potentially malignant disorders (OPMDs), gastric ulcers and colorectal adenoma, harbor high risk of cancerous transformation. Early intervention of these lesions is significant to prevent carcinogenesis and improve patients' prognosis. Lycopene, a carotenoid predominantly accumulated in tomatoes, is clinically recommended with its cis structure; as lycopene harbors the most potent antioxidative effects among carotenoids, its chemopreventive effects on the premalignant lesions is noted.

Exploring the role of angiogenesis in fibrosis and malignant transformation in oral submucous fibrosis: a systematic review and meta-analysis.
