Background: Acute lymphoblastic leukemia (ALL) is aggressive cancer, especially in adults as only 20-40 is cured with current treatment regimens. Objectives: The aim of this study is to evaluate prognostic factors and their effects on survival in ALL patients in the Northeast of Iran. Methods: In a descriptive and retrospective study from 2009 to 2015, 48 ALL patients referred to hematology-oncology clinic. Age, sex, fever, blood group, type of ALL and consumption of amphotericin B, forms of cytogenetic, survival in the patients, WBC, hemoglobin, and platelet were checked in the first referral for every patient. The mean follow-up was 27.3 months in which 28 patients (59.3) died. overall survival (OS) was plotted by GraphPad Prism 5 and the Log-rank test was used for analysis of survival with risk factors. Results: The mean age for all the ALL patients at diagnosis was 32.3 years (range, 15-71 years), and 81.3 were male. Of all patients, 62.5 had fever and 25 consumed amphotericin B. 1-, 2-, 3-, 4-, 5-year OS rates were 62.2, 52.7, 40.6, 39.1, 22.2, respectively. 75, 29.2 and 39.6 of patients had WBC < 20 × 103 /µl, Hb < 7 g/dL and platelet < 30 × 103 /µL, respectively. There was a significant difference in survival based on age (P = 0.000). Conclusions: Based on the results, age > 35 years is the most prognostic factor in ALL patients. Also, patients who received amphotericin B had lower life expectancy because these patients were suffering from fungal infection or due to lack of response to antibacterial drugs, they have been treated with amphotericin B. © 2016, Iranian Journal of Cancer Prevention.
