Six hundred and eighty glioma cases (298 glioblastoma (GBM)), 503 meningioma cases, and 1555 controls recruited in the Nordic-UK Interphone study, were analysed in association with three polymorphisms in p53 (rs2287499, rs1042533, rs1625895) and five polymorphisms in ATM ( rs228599, rs3092992, rs664143, rs170548, rs3092993).
In this first assessment of the role of TP53 Arg72Pro polymorphism in a large series of Portuguese glioma tumors, no association was observed with glioma susceptibility or overall survival, except for patients submitted to adjuvant therapy.

Our data suggest that TP53 Pro47Ser and Arg72Pro SNPs are not involved either in susceptibility to developing gliomas or in patient survival, at least in the Brazilian population.

For this study, 164 cases of glioma were evaluated immunohistochemically for IDH1 mutations (R132H and R132S) using anti-IDH1 mAbs (HMab-1 and SMab-1).
This study analyses a series of 184 glioma cases in a tissue microarray (TMA)-based approach to assess the frequency of R132H point mutations in formalin-fixed, paraffin-embedded tissue samples.
As rs78378222 changes the polyadenylation signal of TP53 leading to impaired 3'-end processing of TP53 mRNA, the SNP has strong plausibility for being directly functional contributing to the aetiological basis of glioma.
In stratified analyses by ethnicity, source of controls, and glioma subtypes, the p53 codon 72 Arg/Pro polymorphism did not alter the risk for glioma in population-based, hospital-based, astrocytoma, and oligodendroglioma studies among Caucasian.

Of 158 tumors with sufficient tissue, 110 (70 %) showed nuclear cMYC immunopositivity--most frequent (95 %, χ(2) p = 0.0248) and intense (mean 1.33, ANOVA p = 0.0179) in anaplastic astrocytomas versus glioblastomas (63 %) or low grade gliomas (74 %). cMYC expression associated with younger age as well as p53 immunopositivity (OR = 3.6, p = 0.0332) and mutant IDH1 (R132H) (OR = 7.4, p = 0.06) among malignant gliomas in our cohort.
Thus, there is limited evidence for the association between the</span> TP53Arg72Pro polymorphism and risk of glioma, and more studies are needed to provide a more comprehensive assessment of the association in Asians.
