Resumen: | Background. Expression of hypoxia-related tissue factors in 1p-aberrant oligodendroglial neoplasms diminishes patient outcome. Differentiated embryochondrocyte expressed gene 1 (DEC1) has been described as novel hypoxia-related tissue factor. In our study, we assessed the expression of DEC1 in 1p aberrant oligodendroglial neoplasms and its association with necrosis and expression of hypoxia-inducible factor 1a (HIF-1a), carbonic anhydrase-9 (CA9), and vascular endothelial growth factor-mRNA (VEGF). Materials and methods. 44 primary and 16 recurrent oligodendroglial neoplasms with 1p-aberrations were investigated immunohistochemically for the expression of DEC1, HIF-1a, and CA9. Expression of VEGF was investigated using in situ hybridization. DEC1 expression was correlated with necrosis and with expression of HIF-1a, CA9, and VEGF. Results. DEC1 was expressed in tumor cell nuclei, and occasionally in nuclei of endothelial cells, and glial and neuronal cells of surrounding brain tissue. High expression (>10% of tumor cells immunolabeled) of DEC1 was found in 56 cases, low expression (<10% of tumor cells immunolabeled) was found in 3 cases. In 1 case no expression of DEC1 was evident. DEC1 expression showed no topographical association with necrosis or expression of HIF-1a, CA9, or VEGF. Conclusion. DEC1 expression is found in the majority of 1p-aberrant oligodendroglial neoplasms and does not correlate with necrosis or expression of HIF-1a, CA9, VEGF. Thus, immunohistochemical analysis of DEC1 expression is in our hands not suitable for detection of tissue hypoxia in this type of primary brain tumor. |
