Abstract | Although the p53 tumor suppressor gene is well known to be involved in the pathogen esis of malignant astrocytomas, its significance in the development of low-grade glio mas, including the nonastrocytic tumors, remains underexplored. In an attempt to further understanding the molecular genetics of glial tumorigenesis, 37 low-grade gliomas of different histologic subtypes were screened for p53 mutations with the polymerase chain reaction, single-strand conformation polymorphism analysis and direct DNA sequencing. Forty-eight tumors, including the previously mentioned 37 cases, were examined immunohistochemically with paraffin-embedded tissues for p53 protein labeling. Only two diffuse astrocytomas exhibited p53 genetic abnormalities, and both tumors behaved aggressively. Two tumors exhibited p53 protein immuno labeling, including one of the cases with genetic changes. p53 genetic alterations are only rarely involved in the pathogenesis of low-grade gliomas. The authors speculate that they occur late in the transition from low-grade to high-grade tumors. Int J Surg Pathol 1 (3):163-170, 1994 © 1994, Sage Publications. All rights reserved. |
