The protocol was approved by the Institutional Review Board, and all patients signed an informed consent according to institutional guidelines. Management of acute promyelocytic leukemia: recommendations from an expert panel on behalf of the European LeukemiaNet. using L‐ATRA.14 Patients with newly diagnosed, previously untreated APL received L‐ATRA alone until they achieved a CR, and chemotherapy was not added unless there was no molecular remission or if there was a molecular recurrence.

Three patients required chemotherapy after a molecular recurrence was detected.14 Using a different approach, 19 previously untreated patients with APL received a combination of gemtuzumab ozogamicin (mylotarg) and ATRA. As2O3 appears to be a safe and effective agent for the treatment of patients with APL. Our observation was similar to that of Soignet et al.,10 who found that 16 of 40 patients (40%) who were treated developed QT‐c prolongation, but no fatal arrhythmias were reported. Nevertheless, at least 20–30% of patients with APL eventually develop recurrent disease and require salvage therapy.3 Until recently, this consisted of combination chemotherapy and/or allogeneic stem cell transplantation. Current first- and second-line treatment options in acute promyelocytic leukemia. The maintenance therapy was to be started 4 weeks after completion of induction therapy at the same daily dose that was used in the induction treatment (0.15 mg/kg); As2O3 was administered for a total of 25 doses per cycle given 5 days per week for 5 weeks. 0 0. coby.

The current results compare favorably with those obtained with ATRA as salvage therapy. Involvement of PML-I in reformation of PML nuclear bodies in acute promyelocytic leukemia cells by leptomycin B. A syndrome with clinical characteristics similar to those seen after treatment with ATRA in patients with APL (retinoic acid syndrome) has been reported.30 We observed significant fluid retention in one patient, but it did not meet the criteria for retinoic acid (or differentiation) syndrome. Impact of arsenic trioxide in the treatment of acute promyelocytic leukemia. Efficacy of Transarterial Embolization with Arsenic Trioxide Oil Emulsion in a Rabbit VX2 Liver Tumor Model.

In its turn arsenic possible oxidation states are -3, +3 and +5. Epub 2018 Aug 25. Some studies suggest that As2O3 induces APL cell differentiation through direct or indirect activation of RAR‐related signaling pathways.18 This may translate into potential synergy in vitro of As2O3 and ATRA.19 A first attempt with this combination was reported by Shen et al. Clinically, patients with APL present with a unique tendency to disseminated intravascular coagulopathy, which increases their morbidity and mortality during induction.1 The current standard treatment for patients APL consists of all‐trans retinoic acid (ATRA) and an anthracycline with or without cytarabine. Twelve of 18 treated patients (67%) achieved a CR. The results showed that APL patients who developed hyperleukocytosis had a higher plasma iAs%, but a lower MMA% and PMI than those who did not develop hyperleukocytosis during As2O3 treatment. Eligibility criteria included 1) confirmation of t(15;17) by conventional cytogenetic analysis or positive reverse transcriptase‐polymerase chain reaction (RT‐PCR) assay for PML‐RARα or fluorescence in situ hybridization (FISH) showing evidence of RARα or PML translocation; 2) adequate renal function (creatinine ≤ 2.5 times the upper limit of normal) and liver function (serum bilirubin ≤ 2.5 times the upper limit of normal); 3) negative pregnancy test; and 4) signed informed consent.
