Abstract

Background. Apoptosis is a genetically programmed form of cell death, of which caspases are the central components. Methods. By tissue microarray of 229 cases of oral squamous cell carcinoma (OSCC), we analyzed the immunoexpression of caspases 3, 6, 7, 8, 9, and 10. Results. All proteins that we examined were expressed in primary OSCC samples. Caspases 8 and 9 were prominently expressed, and caspases 3, 6, 7, and 10 were occasionally expressed. Disease-free survival differed significantly between caspase 7 high-expressing and low-expressing patients, and our multivariate analysis suggested that expression of caspase 7 is an independent prognostic factor for patients with OSCC. Conclusion. This study suggests that caspases regulate the tumorigenesis of OSCC and that caspase 7 expression is a predictor of locoregional recurrence of OSCC. (C) 2010 Wiley Periodicals, Inc.
