sis. There were 30 pts with good, 70 pts with intermediate and 9 pts<br />

with unfavorable prognosis. Among 70 pts with interemediate risk cytogenetics,<br />

67 pts had normal karyotype. The expression <strong>of</strong> P-gp in <strong>the</strong><br />

whole group was from 0.2% to 84.3% (mean: 14.5% ±16.1). Pts with<br />

unfovorable prognosis had higher Pgp expression (24.4%, SD=21.3) than<br />

pts with interemediate (15.6%, SD=15.7), and pts with good risk cytogenetics<br />

(10.7%, SD=14.4). Using <strong>the</strong> Student’s t-test <strong>the</strong>re was statistical<br />

significant difference in MDR1 expression between unfovorable and<br />

good risk group (p=0.033). The statistical analysis showed significant differences<br />

(p0.1% were associated with improved LFS and OS. AML patients<br />

with HGs in marrow sample in first CR have significant higher LFS<br />
