Patient blood management (PBM) is an evidence-based, patient-focused approach to optimize the management of patient and blood transfusion. While PBM is relatively well established in perioperative care, it is not as well established in the medical field. Since anemia in medical patients is heterogeneous and complex in its pathogenesis, the evidence for the threshold of hemoglobin for red blood cell (RBC) transfusion and the use of erythropoiesis-stimulating agents (ESAs) is not strong. While anemia seems to be an adverse risk factor for mortality, it is uncertain if rapid correction of anemia through RBC transfusion can reverse the negative impact of anemia on clinical outcomes. The introduction of ESA is a breakthrough in reducing RBC transfusion and managing anemic patients with renal disease and cancer. Despite promising results from early trials, the United States Food and Drug Administration issued a black box warning for ESAs in 2007 because of concerns about higher mortality, serious cardiovascular and thromboembolic events, and tumor progression. Therefore, the individualized approach to each patient with anemia is recommended in various medical conditions such as acute coronary syndrome, heart failure, chronic kidney disease, and malignancies.

The treatment outcomes of chronic myeloid leukemia in chronic phase (CML-CP) have dramatically improved with comparable life-expectancy to average of general population in tyrosine kinase inhibitor (TKI) era. However, less than a half of patients who started with TKI can remain on frontline TKI. The reasons of switching TKI can be either intolerance or the lack of efficacy. Although a kinase domain (KD) mutation can guide to select salvage TKI from the point of view on the efficacy of TKIs, many factors need to be considered before choosing next-line TKI such as the high-risk features of CML, the adverse events with prior TKI, and the comorbidities of patients. The therapeutic options for CML-CP after failing frontline TKI due to treatment failure or suboptimal responses will be reviewed including allogeneic hematopoietic stem cell transplantation.

Chronic lymphocytic leukemia is a genetically heterogeneous disease, and a complex set of genetic alterations is associated with its pathogenesis. CLL is the most common leukemia in the western countries, whereas it is rare in Asia, including Korea. The prognostic models integrate the traditional staging systems developed by Rai et al. and Binet et al. with biochemical and genetic markers. With the advent of molecular biology, a variety of targeted agents, including anti-CD20 antibodies, inhibitors of BCR signaling pathway, and BCL-2 inhibitors, have been introduced, which has changed the landscape of CLL treatment greatly. This review will focus on the risk stratification and the management of CLL in the era of novel small molecules.

Background: The global TARGET survey examined real-world management of chronic myeloid leukemia (CML) compared with international guideline recommendations. This report focused on the responses of physicians from South Korea compared with those of physicians from the rest of the world (ROW). Methods: The self-administered, online survey, comprising 23 questions and clinical case scenarios, was completed between April and August 2017. It was designed to gather information on practicing physicians and local practices for CML diagnosis, disease monitoring, treatment, and adverse event (AE) management. Results: While there were similarities in the mutation analysis and treatment efficacy between Korea and the ROW, there were also differences in CML management. Initial diagnostic testing was more comprehensive in Korea than in the ROW, and there was significantly better access to standardized polymerase chain reaction testing. Assessment of BCR-ABL levels during the first 12 months of treatment was excellent in Korea, and there was greater frontline use of second-generation BCR-ABL tyrosine kinase inhibitors. Korean physicians were significantly less likely to switch therapy for hematologic AEs. Treatment-free remission was not an important goal of therapy among Korean or ROW physicians. Conclusion This study identified some differences in the current CML management between Korea and the ROW; CML management in Korean patients was generally in line with the current guidelines.
