Survivin, a Potential Early Predictor of Tumor Progression in the Oral Mucosa
1 Institute of Dental Sciences, Faculty of Medicine, University of Ancona, Ancona, Italy; Correspondence: * corresponding author, Via Carelli 28, 71100 Foggia, Italy, lomuziol{at}tin.it or llomuzio{at}tin.it Survivin is a recently described apoptosis inhibitor selectively over-expressed in most tumors. Immunohistochemistry was used to investigate a potential role of survivin as an early predictor of malignant transformation in precancerous and cancerous lesions of the oral cavity. Survivin was present in 10/30 cases (33%) of oral precancerous lesions without malignant progression, and in 15/16 cases (94%) of oral precancerous lesions evolved into full-blown squamous cell carcinoma. Tumors that progressed from these precancerous lesions retained widespread survivin positivity (100%). Variations among group means were highly statistically significant (p < 0.001). No significant correlation was found between survivin expression and the degree of dysplasia. High expression of cytoplasmic/nuclear survivin is an early event during oral carcinogenesis and may provide a useful tool for the identification of precancerous lesions at higher risk of progression into invasive carcinoma.
Key Words: survivin precancerous lesion IAP oral squamous cell carcinoma apoptosis
