The 14 patients who achieved at least MiCyR using one of the last TKI therapies also had an improved EFS how the 14 patients with primary cytogenetic resistance, 70 specifically.5% vs 16.2% (= .02). go through allogeneic stem cell transplantation or receive third-line therapy having a different tyrosine kinase inhibitor (TKI). It’s been demonstrated how the effectiveness of third range nilotinib or dasatinib is bound,7 so that it can be of paramount importance to recognize those individuals probably to reap the benefits of a third-line TKI. With this research we present our encounter managing having a third TKI individuals still in CP who’ve failed both imatinib and second-line dasatinib or nilotinib.
