Acute promyelocytic leukemia, centre, experience, Turkey.

Acute promyelocytic leukemia (APL) is a specific type of acute myeloid leukemia (AML) and has distinct hematopathologic, cytogenetic, clinical and molecular features. This study was a retrospective review of 18 adult patients (10 male, 8 female; mean age of 32.17 ± 5.66 (15-61 years) with APL at our department from January 2006 to December 2011. Following induction therapy, 17 patients achieved CR, 1 of 18 patients died of result bleeding within thirty-sixth hours of admission. In two of 18 patients developed RAS. The relapse rate was 27% (5/18). Fourteen of 18 patients (77%) have been followed in remission. APL is a malignancy requiring quick diagnosis, efficient treatment and supportive care system. ATO, one of the important therapy option in the treatment of APL, cannot be obtained easily in developing countries. This may lead to an increase in the mortality rates. The studies should be made with more number of patients and a longer period of time for accurate results.
