ABSTRACT
<p><b>OBJECTIVE</b>To evaluate cyto- and molecular genetic characteristics of adult patients with acute lymphoblastic leukemia (ALL) and its prognostic significance.</p><p><b>METHODS</b>Two hundred and seventeen adult patients with ALL were analyzed for cyto- and molecular genetic characteristics with combined conventional cytogenetics, fluorescence in situ hybridization (FISH), real-time quantitative PCR (qPCR) and nested PCR. Significance of genetic findings for prognosis was evaluated.</p><p><b>RESULTS</b>t(9;22)(q34;q11)/BCR-ABL has been the most frequent abnormality found in the cohort (56.3%). And 22.4% of cases with BCR-ABL detected by FISH was negative by cytogenetic analysis. Ratio of patients in high-risk group increased with age; Patients with B-ALL had a higher risk group than the average-risk group (98.40% vs. 65.70%, P=0.000). The overall survival (OS) rates at 3-month (67.30% vs. 85.10%, P=0.042), 6-month (55.1% vs. 80.4%, P=0.008), 12-month (34.0% vs. 59.1%, P=0.017) and 24-month (13.0% vs. 36.6%, P=0.010) were lower in high-risk group than in average-risk group, with medium OS time (11 months, 95% CI 8.0-13.9) being significantly shorter compared with the average-risk group (19 months, 95%CI 10.8-27.1).</p><p><b>CONCLUSION</b>Adult patients with ALL have unique cyto- and molecular genetic characteristics, which has important value for prognosis and guiding treatment. Moreover, combined cytogenetic and molecular genetic techniques can precisely define sub-groups of ALL patients.</p>
