Expression of antiapoptotic proteins livin and survivin in pediatric AML patients, as prognostic markers.

Objective: Survivin and livin are highly expressed in various malignancies and their expression levels may be related to unfavorable prognosis. The aim was to investigate the relationships of these two markers with some prognostic factors and with survival of the children with acute myeloid leukemia (AML).

Methods: Livin and survivin expression was investigated quantitatively by immunohistochemistry staining technique in 43 primary formalin-fixed, paraffin-embedded bone marrow blocks in pediatric age group (<18 years).
