- Beschreibung: Abstract In elderly pts, the prognosis of AML associated with poor risk cytogenetics or secondary to either MDS or previous cancer is so bad that only supportive care or investigational studies are usually recommended. Fit patients may achieve CR after conventional induction, but early relapse appears to be nearly inescapable whatever classical consolidation or maintenance therapy is used. Therefore, the GOELAMS investigated the impact of a maintenance using two agents mainly used in MDS, ie AZA and Len. Between March 2011 and February 2013, 117 pts from 27 centers (median age 69 yrs; 60-80) with previously untreated poor prognosis AML were included. Poor Risk factors were either preceding MDS (n=52), previous cancer (n=37) or centrally reviewed (IL) poor risk cytogenetics (n=83) defined as complex karyotype (≥3 abnormalities, n=65), monosomal karyotypes (n=54), del or - 5 (n=61) or 7 (n=44), 3q abnormality (n=9) or MLL rearrangement except for t(9;11) (n=5). Median WBC was 2.9 G/L (0.5-160), 7 pts had WBC ≥ 30 G/L. Induction chemotherapy included Lomustine 200 mg/m² po d1, Idarubicine 8 mg/m²/d (d1-5), Cytarabine 100mg/m²/d CI (d1-7). Patients in CR received 12 maintenance cycles alternating every 28 days AZA (sc 75 mg/m²/d1-7) and Len (10mg/d1-21), which started if PMN and platelets were >1 G/L and 100 G/L respectively. After d42, subsequent cycles were reduced to 50 mg/m²/d and 5 mg/d. GCSF was allowed in case of PMN < 0.5 G/L after 7 days or febrile neutropenia. At the end of induction, CR was achieved in 56% (65 pts) without any predictive factor, 9% died from infection (n=6), cerebral hemorrhage (n=1) or MOF (n=4) and 35% (41pts including 5 CRp) failed to achieve CR. The 12 planned maintenance courses could be given to 21 pts (32%) (median: 6). Few toxicities were observed. AZA courses were slightly more toxic than Len courses (table 1).

Twenty Gr3/4 AE were reported among 441 cycles (0.56%/courses). Median follow-up for survivors was 38 mo (26-47). Median OS was 10 mo, with 21% 2y OS. Median CR duration was 7 mo (1-30). Impact of prognostic factors on DFS is shown table 2. Within poor risk factors, Cytogenetic abnormalities appeared as even poorer than previous MDS or cancer.

In the present study, the DFS of the group of pts with poor risk cytogenetics without previous cancer or MDS is very similar. This alternating azacitidine/lenalidomide maintenance improved DFS and OS of pts without poor risk cytogenetics (median 15.7 and 24 mo). In this setting, it could be randomly compared to conventional chemotherapy maintenance. Figure 1. Figure 1. Disclosures No relevant conflicts of interest to declare.
