Abstract:
Objective To investigate the relationship of programmed cell death 4(PDCD4) with the invasion of astrocytic glio-mas .Methods Using the immunohistochemical method to detect the expression of PDCD4 in astrocytic gliomas in different grades . Measuring the peritumoral low-density area on MRI scan ,then compared with the results of immunohistochemical expression .Re-sults The downregulation of PDCD4 was with the increasing of the malignant grade of astrocytic gliomas .The tumor grade malig-nancy was positively correlated with the grade of the peritumoral low-density area on MRI scan(P<0 .05) ,while the expression of PDCD4 was negatively correlated with the grade of astrocytic gliomas (P<0 .01) .Conclusion PDCD4 might serve as one of the in-dicators of invasion and malignant phenotype for astrocytic gliomas .
