Abstract
Background:Despite the notable advances in modern surgery and radiotherapy,no significant increase in the five year survival rate of oral squamous cell carcinoma has been reported. Collecting evidence demonstrates that miR 153 and miR 455-5p play a key role in growth and progression of oral cancer. Early detection of OSCC is important for enhancing patient quality of life and clinical treatment.For this reason, biomarkers or tumour markers offer an opportunity to intervene and avoid development of oral cancer. Methods:A total of 50 blood samples from patients from both genders (25 OSCC and 25 healthy people/control groups) were obtained to determine the expression of miR153 and miR455-5p using Real time Polymerase chain reaction and t test. Results:In general by using the formula Δ ct, it is evident that the miR 153 expression in peripheral blood is lower in patients than in healthy individuals (1.97) while the miR 455-5p expression in peripheral blood is higher in patients than in healthy individuals (2.56). Conclusion:We conclude that miR153 and miR 455-5p expression in serum can function as a diagnostic screening test for the early detection of oral squamous cell carcinoma.

Summary
Oral squamous cell carcinoma is a malignant tumor which is derived from stratified squamous epithelium (Tumuluri et al, 2002). It is one of the prominent cancers in the oral cavity (Ramos et al, 2010). Despite the notable advances in modern surgery and radiotherapy,no significant increase in the five year survival rate of oral squamous cell carcinoma has been reported. Detection of OSCC is important for enhancing patient quality of life and clinical treatment.For this reason, biomarkers or tumour markers offer an opportunity to intervene and avoid development of oral cancer. Conclusion: We conclude that miR153 and miR 455-5p expression in serum can function as a diagnostic screening test for the early detection of oral squamous cell carcinoma
