Coexpression of CD10/Bcl6 (germinal center-like immunophenotype) was found in 13%, t(14;18) translocations in 17.9%, and MGMT methylation in 75.9% of cases.     ///    "To investigate prevalence and interrelationship of recently suggested molecular prognostic markers in Middle East DLBCL, we analyzed coexpression of CD10/Bcl6 (by immunohistochemistry), t(14;18) translocations (by fluorescence in situ hybridization), and methylation of the gene encoding the DNA repair enzyme O(6)-methylguanine DNA methyltransferase (MGMT) in a series of 190 DLBCL patients from Saudi Arabia with clinical follow-up data. "    ///    t(14;18) was significantly associated with CD10/Bcl6 coexpression (46.7%) but infrequent in CD10-/Bcl6-negative lymphomas (9.4%.     ///    There was a trend toward better prognosis (although statistically insignificant) in tumors with coexpression of CD10/Bcl6.
