Background: Cytogenetic analysis performed at diagnosis is considered to be the most important prognostic factor in AML. Objective: The purpose of this study was to observe the pattern of cytogenetic abnormalities in adult patients with de novo AML. Method: Total fifty-two newly diagnosed de novo AML patients were selected for the study. Six cytogenetic abnormalities including t(8;21), t(15;17), inv(16), BCR-ABL1, FLT3-ITD & NPM1 mutations were detected by Real-Time PCR. Results: In this study, 36 (69.2%) patients showed different cytogenetic abnormalities. The t(15;17) was found to be the most common. t(15;17), t(8;21) and inv(16) were found only in M3, M2 and M4 FAB subtypes, respectively. Significant association was found with increasing age and cytogenetic risk groups. BCR-ABL1 mutation showed significant relation with increased age. FLT3-ITD mutation showed significant association with increased WBC count and inv16 was significantly associated with relatively less bone marrow blast percentage. Conclusion: Cytogenetic study should be performed routinely in all cases of AML for proper diagnosis, prediction of prognosis and implementation of effective therapeutic measures.
