- W2968222794 abstract "6615 Background: ATRA administration in suspected APL patients (sAPL) is thought to impact early death rate (EDR) (Tallman and Manji, Blood Cells Mol Dis. 2011). Delay in ATRA therapy at specialized centers was associated with EDR (Altman et al Blood 2011). EDR within this study was significantly lower compared to the SEER database (12% vs 17.3%) and hence may not reflect overall delay in ATRA therapy. We determined time to ATRA therapy in sAPL, and fraction of sAPL that did not have disease. Methods: Retrospective analysis of patients that received ATRA for newly diagnosed s APL between 01/01/98-12/31/11 at Albany Medical Center. Time to hematologist evaluation, ATRA ordered and administered, and mortality data was collected from cancer registry, medical record, and chemo-pharmacy database. Results: A total of 39 patients with newly diagnosed sAPL were administered ATRA (46% male, mean age 50y). APL diagnosis: 29/39 (75%) true APL (APL); 9/10 ATRA-treated non-APL (A-nAPL); and one patient for whom cytogenetic data unavailable. EDR amongst APL was 5/29 (17%) compared to 2/9 (22%) within A-nAPL. Time variables were compared between APL patients that died early (<30d) to those that survived 30 days, and included: time to hematologist response (0.9d vs. 0.4d); time to ATRA ordered (2.9d vs. 2.0d); time to ATRA administered (3.4d v. 2.2d); and time elapsed between hematologist response to ATRA administered (2.5d v. 1.9d), respectively. Cryoprecipitate was administered to 1/5 (20%) patients who expired within 30d compared to 10/23 (43%) who survived. Overall mortality for APL was 9/29 (31%) compared to 4/9 (44%) for A-nAPL group. Compared to recent reports, time to ATRA administration in our institution was later (2.0d vs. 2.4d). Conclusions: Our data indicate that APL patients who survived 30d received ATRA early. EDR at our institution is comparable to that reported by SEER database and may be attributed to delay in ATRA administration. Higher fraction of patients that survived 30d received cryoprecipitate. Hence aggressive blood product support may contribute to improved survival. Timing at which these products were administered is currently being evaluated." @default.
