The incidence of venous thromboembolism (VTE) is lower in Asian populations than in Western populations. The objective of the present study was to evaluate the annual age- and sex-adjusted incidence (ASR) of VTE from 2009 to 2013 in South Korea. In addition, annual change in the pattern of VTE treatment during the study period was estimated because a new direct oral anticoagulant (DOAC) had become available and was covered by health insurance in Korea beginning in January 2013. VTE cases from 20

DNA-methyltransferase inhibitors (DNMTis), such as azacitidine and decitabine, are used clinically to treat myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Decitabine activates the transcription of endogenous retroviruses (ERVs), which can induce immune response by acting as cellular double-stranded RNAs (dsRNAs). Yet, the posttranscriptional regulation of ERV dsRNAs remains uninvestigated. Here, we find that the viral mimicry and subsequent cell death in response to decitabine

BACKGROUND: Vitamin C suppresses leukaemogenesis by modulating Tet methylcytosine dioxygenase (TET) activity. However, its beneficial effect in the treatment of patients with acute myeloid leukaemia (AML) remains controversial. In this study, we aimed to identify a potential predictive biomarker for vitamin C treatment in AML. METHODS: Gene expression patterns and their relevance to the survival of AML patients were analysed with The Cancer Genome Atlas (TCGA) and Therapeutically Applicable Rese

Although autologous and allogeneic hematopoietic stem cell transplantation (HSCT) are fundamentally different procedures, a tailored approach to bacterial bloodstream infection (BSI) according to the type of HSCT has not yet been suggested. We evaluated the characteristics of BSI after HSCT, with a focus on comparison of BSIs between recipients of autologous HSCT (auto-HSCT) and allogeneic HSCT (allo-HSCT). Among 134 patients (59 received allo-HSCT and 75 received auto-HSCT) who underwent HSCT,

This study aimed to elucidate patterns of disease transformation to secondary myelofibrosis (SMF) or secondary acute myeloid leukemia (SAML) and the development of second primary malignancies in South Korean patients with BCR-ABL1-negative myeloproliferative neoplasms (MPNs). By using nationwide public health care insurance claims data, we identified and analyzed 7454 patients with MPNs who were newly diagnosed with essential thrombocythemia (ET), polycythemia vera (PV), or primary myelofibrosis

OBJECTIVE: Nail toxicity is one of the most frequent non-hematologic toxicities of docetaxel and often deteriorates patients' quality of life, leading to treatment discontinuation. To define the incidence of nail change as well as its association with specific risk factors, we prospectively investigated data of 84 consecutive patients with advanced non-small cell lung cancer who received first-line docetaxel/cisplatin combination chemotherapy. METHODS: Chemotherapy-naïve patients were treated wi

Venous thromboembolism (VTE), which includes pulmonary embolism and deep vein thrombosis, is a condition characterized by abnormal blood clot formation in the pulmonary arteries and the deep venous vasculature. It is often serious and sometimes even fatal if not promptly and appropriately treated. Moreover, the later consequences of VTE may result in reduced quality of life. The treatment of VTE depends on various factors, including the type, cause, and patient comorbidities. Furthermore, bleedi

The aim of the current study is to evaluate the prognostic value of anemia, an easily estimable parameter in patients with diffuse large B-cell lymphoma treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) immunochemotherapy. A total of 157 patients with newly diagnosed diffuse large B-cell lymphoma treated with ≥1 cycle of R-CHOP were included. Hemoglobin level without red cell transfusion within 7 days of initiation of treatment was chosen as a para

Extranodal natural killer/T-cell lymphoma, nasal type (nasal ENKTL) is a distinct clinicopathologic entity of lymphoid tumors with variable size and differentiation of tumor cells. Nasal ENKTL is related to infection of the tumor cells with Epstein-Barr virus (EBV) and virtually all cases contain monoclonal episomal EBV DNA and detectable EBV encoded small nuclear RNAs (EBERs). Several clinical factors are known for their relation to the prognosis, but histopathologic prognostic factors of nasal

The relationship between histopathologic characteristics and treatment outcomes in patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab-based immunochemotherapy needs re-evaluation. Patients with newly diagnosed DLBCL treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) were evaluated with respect to clinical characteristics, treatment efficacy, and survival. Immunohistochemistry of bcl-2, CD10, bcl-6, and MUM-1 was performed and pat

Epidemiologically, multiple myeloma (MM) is a malignant disorder of plasma cells with a higher incidence among Western populations than among Asians. However, there is growing evidence of a recent increase in the age-standardized incidence rate (ASR) of MM in Asian countries, particularly Korea. Application of novel agents has resulted in significant improvement of treatment outcomes, and the advances are ongoing with the recent introduction and U.S. Food and Drug Administration's approval of ne
