The authors report the experience of The M. D. Anderson Cancer Center with As2O3 in the treatment of patients with recurrent APL. Epub 2014 May 8. : Twenty patients with newly diagnosed APL were treated with As2O3 (0.16 mg/kg per day) and ATRA (45 mg/m2 per day) until they achieved a CR. At the time of morphologic CR, 7 of 10 patients who were evaluated by PCR analysis (70% of patients; 95% confidence interval; 0.35–0.93) achieved a molecular remission. 2014 Jul;132:156-67. doi: 10.1016/j.envres.2014.03.012. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). Phase 1 trial and pharmacokinetic study of arsenic trioxide in children and adolescents with refractory or relapsed acute leukemia, including acute promyelocytic leukemia or lymphoma. trans reported 8 of 11 tested patients in molecular CR after two courses of therapy. As2S3: (arsenic oxidation state) Let oxidation no of arsenic be x. There is little information on the frequency of molecular remissions with ATRA alone, because this agent is used most frequently in combination with chemotherapy during induction. All 12 patients achieved CR. The data showed that the energy separation (eV) between As2O5 and As2S3 was 5.8, between As2O3 and As2O5 was 3.6, and between As2S3 and As2O3 was 2.1. Journal of Vascular and Interventional Radiology. Arsenic Trioxide and Acute Promyelocytic Leukemia: Clinical and Biological. Arsenic(III) oxide react with sodium hydroxide to produce sodium orthoarsenite and water. AS3MT, GSTO, and PNP polymorphisms: impact on arsenic methylation and implications for disease susceptibility. Still, is important that patients who are treated with As2O3 are monitored closely for cardiac and electrolyte abnormalities. Role of Arsenic Trioxide in Acute Promyelocytic Leukemia. 2010 Jul 13;18(1):88-98. doi: 10.1016/j.ccr.2010.06.003. Sodium hydroxide - concentrated solution. Upon recurrence, he received ATRA without response, achieved a remission after treatment with idarubicin plus cytarabine, and was consolidated with 1 cycle of the same regimen, developing recurrent disease after 56 weeks. Although As2O3 is known to regulate activation of several signaling cascades, the key events, accounting for its antileukemic properties, remain to be defined. De Loma J, Skröder H, Raqib R, Vahter M, Broberg K. Toxicol Appl Pharmacol. This glassy, white, deliquescent solid is relatively unstable, consistent with the rarity of the As(V) oxidation state.

Have all-trans retinoic acid and arsenic trioxide replaced all-trans retinoic acid and anthracyclines in APL as standard of care. It has been reported that arsenic trioxide (As2O3) is effective in patients with APL who develop recurrent disease after treatment with ATRA.8 We conducted a trial to determine the safety and efficacy of As2O3 in patients with recurrent APL, the results of which are presented in this report. 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. Its minimum oxidation state we can predict as being -3, and its maximum as +5 In AsH3, arsenic has oxidation number -3, but in AsF3, arsenic has oxidation number +3. Remission duration was measured from the date when CR was achieved to the date of clinical recurrence. | Arsenic in As2O3 is oxidized from +3 to +5, and oxygen in H2O2 is reduced from -1 to -2. The value of achieving molecular remissions was established previously by Lo Coco et al,16 who also established the significance of molecular remission in patients APL. | On completion of treatment, patients had a bone marrow aspirate for morphology, cytogenetic studies, and RT‐PCR analysis for PML‐RARα. Three patients (50%) achieved a CR; two patients developed recurrent disease after 3 months and 5 months, and one patient underwent transplantation 1 month into CR.11, An important observation in our study was that all 12 patients achieved a molecular remission, including 7 of 10 patients (70%) in molecular remission that was documented at the time of hematologic CR, 3 patients after additional As2O3 maintenance, and 2 patients in molecular remission that was documented posthematologic CR after chemotherapy was added. Find another reaction. Lv 6. 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.

Southwest oncology group phase II study of arsenic trioxide in patients with refractory germ cell malignancies. Secondary objectives included determining the rates of molecular remission, remission duration, and survival. That patient had resolution of symptoms after therapy was finished. 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. … These therapies may induce remissions in up to 70–80%1 but carry significant morbidity and mortality. Arsenic trioxide’s content is 99.94%, extraction yield can reach to 98.92%. As2O3 appears to be a safe and effective agent for the treatment of patients with APL. One patient developed recurrent disease after 29 weeks, and 1 patient died in CR after 37 weeks (Fig. In addition, patients with the AS3MT 14215 (rs3740390) CC genotype had significantly higher plasma iAs% and incidence of hyperleukocytosis, but lower PMI than patients with the CT + TT genotype. The study was an open‐label protocol for patients with recurrent APL. The median duration of induction therapy was 42 days (range, 27–60 days). 0 0. bala. 2018 Nov 1;166(1):219-227. doi: 10.1093/toxsci/kfy210. Relevance. Hematology/Oncology Clinics of North America.

Mutant Transcription Factors and Tyrosine Kinases as Therapeutic Targets for Leukemias: From Acute Promyelocytic Leukemia to Chronic Myeloid Leukemia and Beyond. The early studies from China did not describe any molecular analysis.7, 12 Warrell et al.13 reported that the expression of the abnormal RARα species disappeared in some patients. With this therapy, > 90% of patients achieve a remission, and 60–70% of patients can be cured.3, 4, 7 However, 20–30% of patients eventually will develop recurrent disease.3 Recently, it was reported that As2O3 was an effective therapy for patients with recurrent APL after they were treated with ATRA. The patient who presented in third recurrence was treated originally with ATRA, achieved a CR, and developed a recurrence after 168 weeks. Our channel. Hydrogen peroxide inhibits activity of the IGF-1 receptor kinase. Eight patients continued in CR after a median follow‐up of 24 months (range, 9–45 months). Chemotherapy of acute leukemia in adults. It has been reported that arsenic trioxide (As2O3) is effective in this setting. Conversely, we did not observe statistically significant associations between the occurrence of hyperleukocytosis and AS3MT 14458 (rs11191439), 27215 (rs11191446), and 35991 (rs10748835) polymorphisms in our study subjects. O.N. In two patients, the induction dose was adjusted after 2 weeks of therapy to 0.11 mg/kg per day because of fluid retention and epigastric pain (n = 1 patient) and noncardiac chest pain (n = 1 patient). Ten of 12 patients who were investigated for the PML‐RARα rearrangement achieved a molecular remission within 3 months of achieving a hematologic CR. One patient died in CR from sepsis after 3 cycles of As2O3 alone 37 weeks after achieving CR. Ten patients were in first recurrence, 1 patient was in second recurrence, and 1 patient was in third recurrence. 2019 Sep 15;379:114687. doi: 10.1016/j.taap.2019.114687. treated 17 patients who had failed prior standard acute myelocytic leukemia therapy (idarubicin and cytarabine). Journal of Agricultural and Food Chemistry. Ten patients are alive currently, with a median follow‐up of 27 months (range, 15–45 months). 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.
