ABSTRACT
Objective To investigate the clinicopathological significances of LDHA/mutant p53 co-expres-sion in gliomas. Methods According to the 2016 WHO CNS,archived 68 gliomas were collected and analyzed retrospectively. The co-expression of LDHA/mutant p53 was detected by immunohistochemical staining. Results High expression of LDHA alone was always found in high grade gliomas(48.5%). Mutant p53 high expression was usually observed in glioblastomas (26.5%). There was a close relationship between co-expression of LDHA/mutant p53 in glioblastoma(27.9%,P = 0.005),or gliomas with high histological grading(27.9%,P = 0.002). Conclusions Co-expression of LDHA/mutant p53 in tumor cells might be a specific immunohistochemical pheno-type of gliomas,and may help for distinguishing glioblastoma and other high grade gliomas from low grade gliomas.
