Brief Summary
Summary Acute promyelocytic leukemia is defined by a characteristic morphology (AML FAB M3/M3v), by the specific translocation t(15;17) and its molecular correlates (PML/RARa and RARa/PML). Thereby it can be separated from all other forms of acute leukemia. By all-trans retinoic acid in combination with chemotherapy cure rates of 70 to 80% can be reached. On average, about 10% of patients still die in the early phase of the treatment and about 20 to 30% relapse. Molecular monitoring of the minimal residual disease (MRD) by qualitative nested RT-PCR and quantitative REAL-time PCR of PML/RARa allows to follow the individual kinetics of MRD and to identify patients with an imminent hematological relapse. A standardized treatment for patients with relapsed APL has not yet been established. With arsenic trioxide (ATO) monotherapy remission rates over 80% were achieved and long-lasting molecular remissions are described. The drug was mostly well tolerated. ATO exerts a dose dependent dual effect on APL blasts, apoptosis in higher and partial differentiation in lower concentrations. ATO was also successfully administered before allogeneic and autologous transplantation. ATO is approved for the treatment of relapsed and refractory APL in Europe and in the USA. In the present protocol, ATO is given for remission induction:
- 1.in patients with hematological or molecular first or subsequent relapse of APL and
- 2.in patients who do not reach a hematological or molecular remission after first line therapy.
- 3.the eligibility for allogeneic transplantation
- 4.the eligibility for autologous transplantation
- 5.the presence or absence of contraindications against intensive chemotherapy
- 6.the PCR status after induction and during follow up (RT-PCR of PML/RARa, sensitivity 10-4)
