Overexpression of c-Myc in primary central nervous system lymphoma of Thais.

Background: c-Myc protooncogenes have been implicated in the tumourigenesis of extracerebral lymphomas, however only afew studies on this oncogenic molecule have been available for primary central nervous system lymphoma (PCNSL).

Objective: To determine the prevalence ofprotein overexpression and gene amplification of c-Myc in PCNSL and to correlate with histological and immunophenotypic subtypes of malignant lymphoma according to WHO classification of tumors of haematopoietic and lymphoid tissue 2001.
