The advent of imatinib has dramatically improved outcomes in patients with chronic myelogenous leukemia (CML). It has become the standard of care for all patients with newly diagnosed chronic-phase CML based on its successful induction of durable responses in most patients. However, its use is complicated by the development of resistance in some patients. Dose escalation might overcome this resistance if detected early. The second-generation tyrosine kinase inhibitors (TKIs) dasatinib and nilotinib provide effective therapeutic options for managing patients resistant or intolerant to imatinib. Recent studies have shown that dasatinib and nilotinib provide quicker and potentially better responses than standard-dose imatinib when used as a first-line treatment. The goal of therapy for patients with CML is the achievement of a complete cytogenetic response, and eventually a major molecular response, to prevent disease progression to accelerated or blast phase. Selecting the appropriate TKI depends on many factors, including disease phase, primary or secondary resistance to TKI, the agent's side effect profile and its relative effectiveness against BCR-ABL mutations, and the patient's tolerance to therapy. In October 2010, NCCN organized a task force consisting of a panel of experts from NCCN Member Institutions with expertise in the management of patients with CML to discuss these issues. This report provides recommendations regarding the selection of TKI therapy for the management of patients with CML based on the evaluation of available published clinical data and expert opinion among the task force members.

The introduction of targeted therapies has revolutionized treatment and improved outcomes in patients with leukemias and lymphomas. However, many patients experience relapse caused by the persistence of residual malignant cells. Cytogenetic and molecular techniques are increasingly being used to assess and quantify minimal residual disease (MRD). The emergence of advanced technologies has led to the discovery of multiple novel molecular markers that can be used to detect MRD and predict outcome in patients with leukemias and lymphomas. Gene expression signatures that predict clinical outcomes in patients with non-Hodgkin's lymphoma have been identified. In chronic myelogenous leukemia, molecular monitoring has become more important in assessing response and detecting resistance to therapy. In acute leukemias, several new markers have shown potential in prognostication and monitoring treatment. In leukemias and lymphomas, microRNAs have been identified that may be useful in diagnostics and prognostication. To address these issues, the National Comprehensive Cancer Network (NCCN) organized a task force consisting of a panel of experts in leukemia and lymphoma to discuss recent advances in the field of molecular markers and monitoring MRD.

Chronic myelogenous leukemia (CML) is usually diagnosed in the chronic phase. Untreated chronic phase CML will eventually progress to advanced phase (accelerated or blast phase) CML. Tyrosine kinase inhibitors (TKIs) have been shown to induce favorable response rates in patients with accelerated and blast phase CML. The addition of TKIs to chemotherapy has also been associated with improved outcomes in patients with blast phase CML. Allogeneic hematopoietic stem cell transplant remains a potentially curative option for patients with advanced phase CML, although treatment with a course of TKIs will be beneficial as a bridge to transplant. This manuscript discusses the recommendations outlined in the NCCN Guidelines for the diagnosis and management of patients with advanced phase CML.

The inaugural NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for acute lymphoblastic leukemia (ALL) were developed as a result of meetings convened by a multi-disciplinary panel of experts in 2011. These NCCN Guidelines provide recommendations on the diagnostic evaluation and workup for ALL, risk assessment, risk-stratified treatment approaches based on the Philadelphia chromosome status and age (adults vs. adolescents/young adults), assessment of minimal residual disease, and supportive care considerations. It is recommended that patients be treated at specialized centers with expertise in the management of ALL.

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).

The classical Philadelphia chromosome–negative myeloproliferative neoplasms (MPN), which include essential thrombocythemia, polycythemia vera, and myelofibrosis (MF), are in a new era of molecular diagnosis, ushered in by the identification of the JAK2V617F and cMPL mutations in 2005 and 2006, respectively, and the CALR mutations in 2013. Coupled with increased knowledge of disease pathogenesis and refined diagnostic criteria and prognostic scoring systems, a more nuanced appreciation has emerged of the burden of MPN in the United States, including the prevalence, symptom burden, and impact on quality of life. Biological advances in MPN have translated into the rapid development of novel therapeutics, culminating in the approval of the first treatment for MF, the JAK1/JAK2 inhibitor ruxolitinib. However, certain practical aspects of care, such as those regarding diagnosis, prevention of vascular events, choice of cytoreductive agent, and planning for therapies, present challenges for hematologists/oncologists, and are discussed in this article.
