Therapy-related acute promyelocytic leukemia (t-APL) has been reported as a late complication of exposure to radiotherapy and/or chemotherapeutic agents targeting DNA topoisomerase II. We have analyzed in t-APL novel gene mutations recently associated with myeloid disorders. Unlike previous reports in acute myeloid leukemia (AML), our results showed neither IDHs nor TET2 mutations in t-APL. However we found an R882H mutation in the DNMT3A gene in a patient with t-APL suggesting a possible role of this alteration in the pathogenesis of t-APL.

Abstract
Therapy-related acute promyelocytic leukemia (t-APL) has been reported as a late complication of exposure to radiotherapy and/or chemotherapeutic agents targeting DNA topoisomerase II. We have analyzed in t-APL novel gene mutations recently associated with myeloid disorders. Unlike previous reports in acute myeloid leukemia (AML), our results showed neither IDHs nor TET2 mutations in t-APL. However we found an R882H mutation in the DNMT3A gene in a patient with t-APL suggesting a possible role of this alteration in the pathogenesis of t-APL.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
