Estudo comparativo da expressão da survivina na citologia esfoliativa da mucosa bucal de pacientes com carcinoma de células escamosas intra-bucal e fumantes crônicos

Survivin protein is an inhibitor of apoptosis that plays a role in cell cycle control and the mechanism of carcinogenesis. The aim of this study was to verify the clinic pathological correlation of survivin expression in exfoliative cytology of chronic smokers, mucosa of patients with intra-oral squamous cell carcinoma (OSCC) and also from mucosa after surgical removal of OSCC. Patients were divided in 03 groups: Group 1: 26 patients who smoked more than 20 cigarettes/day/10years with no history of oral malignant neoplasm, or any clinical sign visible at examination. Group 2: 26 patients who had OSCC and Group 3: 22 patients surgically treated of OSCC for at least 01 month. Immunohistochemistry of the smears from each group was analyzed by light microscopy to extent and intensity of survivin positive cells. Survivin expression was observed in 100% of cases in group 1, 88.5% in group 2 and 100% in group 3. Groups 1 and 3 showed cytoplasmic expression in 100% of the cases, while group 2 showed it in 87.5%. Cytoplasmic and nuclear expression was 7.69% observed only in group 2. The results were association with clinicopathological data by Fisher's exact test and it was significant to smoke cessation in group 2 on intensity (p=0.015) of survivin expression. The intensity of survivin expression was related to smoking cessation in group 2. Smoking history (pack/years) showed no influence survivin expression
