Role of DNA Methylation Profile in Diagnosing Astroblastoma: A Case Report and Literature Review

Conclusion Astroblastoma is an extremely rare CNS tumor. Morphological diagnosis is difficult, as the typical astroblastic rosettes may be present also in other CNS tumors, including some gliomas and ependymomas. In fact, AB can be considered as a morphologic pattern, which can be associated with a spectrum of molecular entities. Total resection is the best treatment; the precise role of chemotherapy and radiotherapy is still debated, particularly for high-grade tumors. We believe that DNA-methylation profiles represents an important instrument for confirming diagnosis, predicting prognosis and better defining the molecular characteristics of AB.
