Abstract
INTRODUCTION: Oral cancer is a major global threat to public health. It is one of the most common causes of mortality and morbidity in the modern era. Oral Squamous Cell Carcinoma (OSCC) accounts for over 90% of the malignancies involving the oral cavity. The enzyme- Butyryl Cholinesterase (BChE) is proposed to have a role in cell proliferation, cell adhesion, cell differentiation, apoptosis and tumorigenesis. Few studies have been conducted for understanding the significance of serum BChE as a biomarker in oral cancer patients; however literature available is insufficient to arrive at a conclusion. There is a need of a simple, rapid, convenient, inexpensive and reliable biomarker of oral cancer. So, the present study is an attempt to estimate the level of BChE in oral cancer, prior to definitive therapy. AIM: To estimate and compare the serum BChE levels in patients with OSCC with age and gender matched healthy controls. MATERIALS AND METHODS: The study comprised of 80 subjects, of which 40 biopsy proven OSCC patients of either sex were selected as cases and 40 healthy, age and gender matched subjects as controls. Estimation of serum BChE levels was done by colorimetric method using RANDOX RX Imola Auto-Analyzer. The statistical analysis between the OSCC group and the control group were done using unpaired t-test. Comparison between serum BChE levels and TNM stages of OSCC were done using Kruskal-Wallis Test. Comparison between serum BChE levels and histopathological grades of OSCC were done using Mann-Whitney U Test. RESULTS: There was statistically highly significant decrease in the mean serum BChE levels in the OSCC group compared to the control group (p<0.001). It was revealed that the serum BChE levels were further decreased in moderately differentiated squamous cell carcinoma than well differentiated squamous cell carcinoma and the difference was statistically significant (p <0.05). CONCLUSION: The decrease in the serum BChE level demonstrates that it as a simple, rapid, convenient, inexpensive and reliable biomarker for oral cancer. Our findings support the concept of role of BChE in apoptosis, cell proliferation, differentiation and its related link in the pathophysiology of oral cancer.
