Background. We evaluated the predictive significance of 14 reported markers using immunohistochemical study in nasopharyngeal carcinoma. Methods. Immunohistochemical stainings were done in 38 patients for Met, cyclooxygenase-2 (COX-2), nm23-H1, epidermal growth factor receptor (EGFR), p63, early growth response factor 1 (Egr1), chromosome segregation 1-like (CSE1L), cathepsin-D (aspartyl protease), C-erbB2, p53, signal transducers and activators of transcription (STAT3/STAT5), CD138 (Syndecan-1), and LIN28 with the usual methods. Results. The median follow-up time was 30 months (11-83 months). High Met and CD138 expression were statistically significant negative prognostic factors on survival. The expression of Egr1 had a positive prognostic effect on survival. The combined score of these 3 markers, Met plus CD138 minus Egr1, was a strong prognostic factor. The median survival curve was distinctly separated in accord with this combined score. No prognostic value was revealed in COX-2, nm23-H1, EGFR, p63, CSE1L, cathepsin-D, C-erbB2, p53, STAT3, STAT5, and LIN28. Conclusions. The combined score of these markers could be used to stratify biomolecular risk groups. (C) 2010 Wiley Periodicals, Inc. Head Neck 33: 1458-1466, 2011
