Abstract/OtherAbstract:
Diagnostic cytogenetic and molecular analysis is recognized as the most valuable prognostic factor in acute myeloid leukemia (AML). Among 2516 consecutive Chinese patients with de novo AML, 2308 patients had successful cytogenetic results including 61 subclasses of cytogenetic abnormalities and 27 kinds of additional cytogenetic abnormalities. The incidence of t(15;17)(q22;q12) was highest (16.7% of 2308 patients), followed by t(8;21)(q22;q22) (15.1%), trisomy 8 (5.5%), loss of Y (4.5%), trisomy 21 (2.4%), inv(16)(p13q22) or t(16;16)(p13;q22) (2.1%), etc. In comparison to children, adults had higher incidence of normal karyotype (41.5% vs. 29.1%, P<0.001) and lower incidences of t(8;21)(q22;q22) (13.4% vs. 25.8%, P<0.001), t(9;11)(p22;q23) (0.2% vs. 1.2%, P=0.001) and other 11q23 rearrangements (1.0% vs. 3.4%, P<0.001). Among 349 AML patients with t(8;21)(q22;q22), 310 (35.5%) were found in 873 patients with M2. The t(15;17)(q22;q12) was exclusively observed in 386 (71.0%) of 544 patients with M3. In 48 AML patients with inv(16)(p13q22) or t(16;16)(p13;q22), 42 (15.2%) were detected in 276 patients with M4. Our study displayed the cytogenetic characteristics in a large series of Chinese patients with de novo AML. Our results revealed the similarities and differences of cytogenetic abnormalities existing between Chinese and western AML patients.
