摘要:We report a case of a patient with chronic myeloid leukemia diagnosed in January 2012 and treated with nilotinib 600 mg/die as first line therapy. Patient obtained a complete hematologic response (CHR) and improvement of splenomegaly in 2 weeks. In three months the patient obtained complete cytogenetic response (CCR) and an important transcript level reduction (less than 1%). According to the international recommendations, molecular analysis was performed every three months in a LABNET network laboratory. Treatment was never interrupted or reduced due to any adverse event. After 9 months patient achieved a major molecular response (MMR) and during evaluation a MR4 has been documented.
