- W2954132446 abstract "e18505 Background: In order to describe the impact of future targeted therapies on treatment outcomes of patients (pts) with relapsed and/or refractory (RR) acute myeloid leukemia (AML), a better understanding of the clinical management pathway in these pts is needed. We therefore evaluated the treatment patterns and associated outcomes in a real-world cohort of pts with RR-AML using a population-based cancer registry and patient medical records. Methods: Pts newly diagnosed wih AML between January 2013 and December 2016, aged ≥ 18 years were identified from the provincial-wide Alberta Cancer Registry (ACR). Data for pts who met the criteria for RR-AML were assessed by hematologists and were extracted from medical records. RR-AML pts were then categorized as: receiving intensive therapy (IT); receiving non-intensive therapy (NIT); or treated with best-supportive care (BSC) following a diagnosis of RR-AML. Results: 572 AML pts were identified from the ACR, of which 199 met criteria for RR-AML and were included in the analysis (124 males, 75 females; median age at diagnosis of RR-AML 66.8 years; median follow-up 4.7 months). In this RR-AML cohort, 26 (13%) pts received ≥ 2 lines of prior therapy. Unadjusted median overall survival (mOS) was 5.3 months, with a 12-month overall survival rate of 29.6% (95% CI 29.0–30.3%) from the time of RR. Following RR, 46 (23%) pts received IT, 65 (33%) pts were treated with NIT, and 88 (44%) pts received BSC, with unadjusted mOS of 13.8, 9.4, and 2.1 months, respectively ( P < 0.001). When stratified by European LeukemiaNet risk classification at diagnosis, unadjusted mOS was 12.4, 4.7, and 4.0 months for favorable risk, intermediate risk, and adverse risk groups, respectively ( P < 0.01). Conclusions: This retrospective, real-world study in Alberta Canada confirms the poor prognosis reported to date in the RR-AML population. Notably, a large proportion of pts received BSC which was associated with dismal survival outcomes. These data also highlight that effective and tolerable alternatives to current treatment options are urgently needed." @default.
