Both p53 codon 72 Arg/Arg and pro/Arg genotypes in glioblastoma multiforme are associated with a better prognosis in bevacizumab treatment. BMC Cancer 2020; 20:709. [PMID: 32727419 PMCID: PMC7391574 DOI: 10.1186/s12885-020-07210-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 07/23/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND It has previously been shown that bevacizumab, when added to chemotherapy, improved overall survival in several cancers. In glioblastoma multiforme (GBM), bevacizumab increased progression-free survival and it is widely used for tumor recurrence, though it has failed to improve overall survival (OS) in controlled trials. However, an effective biomarker for predicting the prognosis of bevacizumab treatment has yet to be identified. This study, therefore, aimed to retrospectively analyze the polymorphisms of p53 codon 72 and the clinical characteristics of GBM specimens from Taiwanese patients. METHODS The polymorphisms of p53 codon 72 in 99 patients with GBM treated at Taichung Veterans General Hospital in Taiwan from 2007 to 2017 were analyzed using direct DNA sequencing and PCR-RFLP analysis. RESULTS We found that among these GBM patients, the distribution of codon 72 polymorphisms was 28.3% for proline homozygotes (Pro/Pro), 38.4% for arginine homozygotes (Arg/Arg), and 33.3% for proline/arginine heterozygotes (Pro/Arg). Although the polymorphisms of p53 codon 72 were not directly associated with the overall survival of GBM, both the Arg/Arg and Arg/Pro genotypes were associated with significant benefits in terms of overall survival in patients treated with CCRT plus bevacizumab compared to patients treated with CCRT alone. CONCLUSIONS This pilot study suggests that both the Arg/Arg and Arg/Pro genotypes of p53 codon 72 polymorphism may have value as independent prognostic or predictive parameters for bevacizumab treatment response and failure. Relatedly, the results of the study further demonstrate the utility of stratifying GBM patients according to bevacizumab sensitivity.

Abstract
TP53 is a tumour suppressor gene frequently mutated in human cancers; nevertheless, in EBV-associated malignancies mutations are uncommon despite frequent deregulation of the p53 pathway. In this study, we aimed to investigate p53 expression, TP53 mRNA levels and TP53 mutations in EBV-associated gastric carcinoma (EBVaGC). A case-control study was performed using 46 patients: 15 EBVaGC and 31 EBV-negative GC (EBVnGC) cases. p53 expression was detected by immunohistochemistry (IHC), the evaluation of p53 mRNA levels was performed by RT-qPCR and TP53 mutations were investigated only in EBVaGC cases using the DNA sanger sequencing method. p53 expression was found in 97.8% (45/46) of all gastric cancer cases (including EBVaGC and EBVnGC groups). Despite the high frequency of p53 expression in both groups, the percentages of cells are significantly higher among EBVaGC cases (p = 0.027). Regarding the mRNA levels, we found a significantly increased expression of p53 mRNA in EBVnGC (2-ΔΔCt = 13.4 ± 2.4; p = 0.0029) when compared with EBVaGC. Furthermore, the sequencing analysis of TP53 gene revealed that only one of the 15 EBVaGC cases presented a missense mutation. Our results demonstrated that EBV-associated gastric carcinomas are characterized by a significant decrease of TP53 mRNA levels with a strong p53 expression and rare TP53 mutations when compared with EBV-negative cancers. Considering these results, EBV seems to induce a stabilization of p53 in the EBVaGC independently of the presence of mutations, which remains to be explained.
