AI Article Synopsis
- The study aimed to explore the link between age, gender, and risk factors associated with the progression of oral submucous fibrosis to oral squamous cell carcinoma in Karachi, Pakistan.
- A total of 1774 patients were analyzed, revealing that a significant portion (26.60%) experienced malignant transformations, predominantly affecting women (78.4%) and individuals aged 26-50 years (56.4%).
- Findings indicate a strong correlation between specific chewing habits, particularly the use of betel quid with tobacco, and the elevated risk of developing oral squamous cell carcinoma.
Article Abstract
Objective: To determine the relationship of age, gender and other associated risk factors linked with malignant transformation of oral submucous fibrosis into oral squamous cell carcinoma.
Methods: This cross-sectional, multi-centre study was conducted at both public and private tertiary care hospitals and clinics of Karachi, Pakistan, from 2004 to 2012, and comprised patients with oral submucous fibrosis and/or oral squamous cell carcinoma. Out of the total sample, malignant transformations of oral submucous fibrosis to oral squamous cell carcinoma were included. Cases of oral squamous cell carcinoma without clinical evidence of pre-existing oral submucous fibrosis were excluded. Sample selection was based on non-probability convenience sampling. SPSS 18 was used for data analysis.
Results: Of the 1774 cases, 765(43.12%) were of oral submucous fibrosis alone, 472(26.60%) were reported as malignant transformation of oral submucous fibrosis into oral squamous cell carcinoma and 537(30.27%) were of oral squamous cell carcinoma without clinically visible oral submucous fibrosis. Of the malignant transformation cases,370(78.4%) involved women and 102(21.6%)men.Besides,5(1.1%)patients were aged below 25 years, 266(56.4%)were 26-50 years and 201(42.6%)were aged 51 years or above, with the mean age of 21.80±3.1, 34.02±2.1 and 40.28±13.1 years, respectively (p=0.001).Moreover, 228(48.3%)patients used betel quid with tobacco, 108(22.9%) consumed areca nut only, 55(11.7%) chewed betel quid without tobacco, 36(7.6%)used naswar, while 45(9.5%)had no chewing habits (p=0.001)..
Conclusions: The risk of developing oral squamous cell carcinoma was high, especially women.

Oral submucous fibrosis (OSF) is a chronic, progressive, and fibrotic condition of the oral mucosa that carries an elevated risk of malignant transformation. We aimed to identify and validate novel genes associated with the regulation of epithelial-to-mesenchymal transition (EMT) in OSF. Genes regulating EMT were identified through differential gene expression analysis, using a LogFC threshold of -1 and + 1 and a padj value < 0.

Head and neck squamous cell carcinoma (HNSCC) is genetically complex and difficult to treat. Detection in the early stage is challenging, leading to diagnosis at advanced stages with limited treatment options. This study examined the collagen triple helix repeat containing 1 gene (CTHRC1) as a potential biomarker and therapeutic target in HNSCC.

Introduction: Dipeptidyl peptidase-4 is known to be involved in the progression of several fibrogenic diseases, but its association with oral submucous fibrosis remains unclear. This study aims to ascertain whether dipeptidyl peptidase-4 plays a role in the pathogenesis of arecoline-induced oral submucous fibrosis.
Methods: We assessed the expression of dipeptidyl peptidase-4 in arecoline-treated epithelial cells and the exosomes derived from cells.

Introduction: Restricted mouth opening has major health implications, such as malnutrition, difficulty in speech, and poor oral hygiene resulting in a functional shortage of the masticatory system. Reduced mouth opening can occur due to trismus, as in the oral submucous fibrosis (OSMF) condition. Excision of fibrous bands in OSMF leads to reestablishment of the mouth opening.

Statement Of The Problem: Oral squamous cell carcinoma (OSCC) is the most common type of oral cancer. During the invasion, tumour cells break through the basement membrane and penetrate the connective tissue to interact with the extracellular matrix. An attempt was made to evaluate the connective tissue changes in different grades of OSCCs, oral submucous fibrosis (OSMF) and Oral Epithelial Dysplasias.
