The 2014 NCCN Clinical Practice Guidelines in Oncology for Chronic Myelogenous Leukemia recommend quantitative reverse-transcription polymerase chain reaction (QPCR) standardized to International Scale (IS) as the preferred method for monitoring molecular response to tyrosine kinase inhibitor (TKI) therapy. A BCR-ABL1 transcript level of 10% or less (IS) is now included as the response milestone at 3 and 6 months. Change of therapy to an alternate TKI is recommended for patients with BCR-ABL1 transcript levels greater than 10% (IS) at 3 months after primary treatment with imatinib. Continuing the same dose of TKI or switching to an alternate TKI are options for patients with BCR-ABL1 transcript levels greater than 10% (IS) at 3 months after primary treatment with dasatinib or nilotinib. The guidelines recommend 6-month evaluation with QPCR (IS) for patients with BCR-ABL1 transcript levels greater than 10% at 3 months. Monitoring with QPCR (IS) every 3 months is recommended for all patients, including those who meet response milestones at 3, 6, 12, and 18 months (BCR-ABL1 transcript level ≤10% [IS] at 3 and 6 months, complete cytogenetic response at 12 and 18 months).

Chronic myeloid leukemia (CML) is defined by the presence of Philadelphia chromosome (Ph), resulting from a reciprocal translocation between chromosomes 9 and 22 [t(9;22] that gives rise to a BCR-ABL1 fusion gene. CML occurs in 3 different phases (chronic, accelerated, and blast phase) and is usually diagnosed in the chronic phase. Tyrosine kinase inhibitor (TKI) therapy is a highly effective first-line treatment option for all patients with newly diagnosed chronic phase CML (CP-CML). The selection TKI therapy should be based on the risk score, toxicity profile of TKI, patient's age, ability to tolerate therapy, and the presence of comorbid conditions. This manuscript discusses the recommendations outlined in the NCCN Guidelines for the diagnosis and management of patients with CP-CML.

The NCCN Guidelines for Chronic Myeloid Leukemia (CML) provide recommendations for the management of chronic-phase and advanced-phase CML in adult patients. The median age of disease onset is 67 years. However, because CML occurs in all age groups, clinical care teams should be prepared to address issues relating to fertility and pregnancy with patients who are of reproductive age at the time of diagnosis. CML is relatively rare in children and there are no evidence-based recommendations for the management of CML in pediatric population. These NCCN Guidelines Insights discuss special considerations for the management of CML during pregnancy and for the management of CML in the pediatric population.
