Background : Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy.
They display a variety of biological behaviours, and several systems have, therefore, been proposed to grade this neoplasm.
Today, the most popular grading systems are Auclair et al, (1992) and Brandwein et al, (2001) grading systems.
Assessment of cellular proliferation, apoptosis and growth molecules are important factors in tumor kinetic which may reflect tumor biological behaviour. Materials and methods : Immunohistochemical analyses of seventeen cases of -fixed paraffin-embedded tissue blocks of MEC of salivary gland origin using (Ki-67, P53 and EGFR) monoclonal antibodies. Results : The samples comprised of ten males and seven females to give male to female ratio (1.4 : 1).
The mean age was (47.06 ± 8.5) years.
The submandibular salivary gland was the most predominant affected site (5 cases).
100 % of cases were EGFR immunopositive.
Only 47 % of MEC cases showed Ki-67 immunopositivity, while P53 immunopositivity were shown in 94 % of MEC cases.
There was no statistically significant correlation regarding P53 or EGFR markers in relation with grading systems.
There was a statistically significant correlation between the expression of Ki-67 marker and Auclair grading system.
There were no significant statistical correlation among markers except between Ki-67 expression and P53. Conclusions : Assessment of tumor biology in term of apoptosis (p53), proliferation (Ki-67) and EGFR are not reflected on tumor grade.
