Mutation status of refractory to imatinib patients with chronic myeloid leukemia

Mutation status of 36 chronic myeloid leukemia (CML) patients in chronic phase with primary and secondary imatinib resistance was analyzed. BCR-ABL mutations identified by direct DNA sequencing. BCR-ABL kinase domain mutations were detected in 30.5 % (11 of 36) of those patients. Most of identified...

BCR-ABL kinase domain mutations were detected in 30.5 % (11 of 36) of those patients. Most of identified mutations were missense mutations: Q252H, M244V, G250E, Y253F/H, E255K/V, T315I, M351T, F359V, F359C, F486S. Patients with BCR-ABL mutations have significantly lower 4-year event-free survival compared with CML patients without mutations (18 % vs. 53 %; р = 0.003). The results can be used as reference information in deciding on therapy in imatinib resistant CML patients with clinically relevant BCR-ABL mutations.https://oncohematology.abvpress.ru/ongm/article/view/72chronic myeloid leukemiabcr-abl mutationsresistanceimatinib
