Abstract
Background: Oral squamous cell carcinoma (OSCC) accounts for nearly 90% of oral malignancies and represents a major global health care problem. It is often preceded by oral potentially malignant disorders (OPMD). Although regular clinical examination forms the backbone for oral cancer screening, subtle lesions go unnoticed and there is a need for more sensitive and specific molecular biomarkers in mass screening of population. Salivary proteomics offer an attractive alternative to serum and tissue testing.
Aims: To find the diagnostic utility of salivary interleukin-6 (IL-6) in the differential diagnosis of OSCC, OPMD from healthy controls.
Study design: In vivo study.
Methods: After approval from the Institutional Review Board, unstimulated whole saliva was collected from 90 subjects, 30 in each group of OSCC, OPMD and controls after ethical clearance. Salivary IL-6 was measured by ELISA, and the results were statistically analysed.
Results: Significant difference in salivary IL-6 was seen between OSCC, OPMD and controls. Receiver operating characteristic curve analysis showed the highest area under a curve of 0.982 in distinguishing OSCC from controls. It showed a sensitivity of 71% and specificity of 100% at a cut-off value of 33.4 pg/mL (P = 0.000). Moderately differentiated OSCC (MDSCC) showed a significant increase in salivary IL-6 concentration compared to well-differentiated OSCC (WDSCC).
Conclusion: Results of the present study showed strong predictive power of salivary IL-6 in distinguishing OSCC from controls. Its levels also increased with tumor aggressiveness from WDSCC to MDSCC. Thus, salivary IL-6 could have a diagnostic and/or prognostic significance in identifying high-risk groups in mass screening of the population.
期刊介绍：
The journal of Oral and Maxillofacial Pathology [ISSN:print-(0973-029X, online-1998-393X)] is a tri-annual journal published on behalf of “The Indian Association of Oral and Maxillofacial Pathologists” (IAOMP). The publication of JOMFP was started in the year 1993. The journal publishes papers on a wide spectrum of topics associated with the scope of Oral and Maxillofacial Pathology, also, ensuring scientific merit and quality. It is a comprehensive reading material for the professionals who want to upgrade their diagnostic skills in Oral Diseases; allows exposure to newer topics and methods of research in the Oral-facial Tissues and Pathology. New features allow an open minded thinking and approach to various pathologies. It also encourages authors to showcase quality work done by them and to compile relevant cases which are diagnostically challenging. The Journal takes pride in maintaining the quality of articles and photomicrographs.
