Context Abnormalities in the control of apoptosis play an important role in tumorigenesis. Survivin is one of eight members of the inhibitor of apoptosis protein family that regulates and integrates cell division and suppresses apoptosis.
Aim The aim of this study was to assess intracellular expression of survivin on malignant myeloid blast cells and its correlation with clinical outcome, overall survival (OS), and other prognostic factors among adult Egyptian patients with acute myeloid leukemia (AML).
Settings and design A total of 120 patients with de-novo AML were treated and followed up in Ain Shams University Hospitals Hematology Units and compared with 60 age-matched and sex-matched normal healthy controls.
Patients and methods All patients received induction chemotherapy under a 3 + 7 regime, whereas AML-M3 patients received an all-transretinoic acid-based regime. Detection of intracellular survivin antigen in myeloid blast cells was done by flow cytometry on bone marrow samples at diagnosis and after chemotherapy.
Results Survivin expression was higher in AML patients at day 0 compared with healthy controls (P = 0.001). The highest survivin level was seen in AML French American British subtypes M5 and M4. A significant positive correlation was found between patients«SQ» age, CD15, CD14, and CD11c expression, whereas negative correlation was found between survivin level and the control group, which included 60 age-matched and sex-matched normal healthy volunteers under complete remission, and event-free survival. Patients with a positive survivin expression have shorter OS compared with patients with a negative survivin expression (log-rank = 3.940, P = 0.047).
Conclusion Higher survivin levels at diagnosis predict poor response to chemotherapy and shorter OS (P = 0.016).
