Immunohistochemistry was performed in paraffin-embedded tumor tissue sections to determine the protein expression statuses in tumor cells.

Risk of recurrent venous thromboembolism and major bleeding according to risk factor profiles in Asian patients: a subgroup analysis EINSTEIN-Extension and EINSTEIN-CHOICE.

Background: Risks of recurrence and major bleeding with extended anticoagulation in Asian patients with venous thromboembolism (VTE) are similar to those in non-Asian patients but risks according to baseline risk factor profiles is not well documented.

Methods: Subgroup analysis of two randomized trials, which compared once-daily rivaroxaban (20 mg or 10 mg) with placebo or aspirin (100 mg) for extended treatment in Asian patients with VTE who had completed 6-12 months of anticoagulation. Index events were classified as unprovoked, provoked by major persistent risk factors, minor persistent risk factors, minor transient risk factors, or major transient risk factors.

Changes in chronic myeloid leukemia treatment modalities and outcomes after introduction of second-generation tyrosine kinase inhibitors as first-line therapy: a multi-institutional retrospective study by the CML Cooperative Study Group.

This study investigated changes in treatment modalities and outcomes of chronic myeloid leukemia in the chronic phase (CP-CML) after the approval of second-generation tyrosine kinase inhibitors (2G-TKIs) for first-line therapy. Patients were grouped into those who underwent TKI therapy up to December 2010 (imatinib era group, n = 185) and after January 2011 (2G-TKI era group, n = 425). All patients in the imatinib era group were initially treated with imatinib, whereas patients in the 2G-TKI era group were mostly treated with dasatinib (55%) or nilotinib (36%).

Possible New Histological Prognostic Index for Large B-Cell Lymphoma.

We conducted a retrospective analysis of GRP94 immunohistochemical (IHC) staining, an ER stress protein, on large B-cell lymphoma (LBCL) cells, intracellular p53, and 15 factors involved in the metabolism of the CHOP regimen: AKR1C3 (HO metabolism), CYP3A4 (CHOP metabolism), and HO efflux pumps (MDR1 and MRP1). The study subjects were 42 patients with LBCL at our hospital. The IHC staining used antibodies against the 17 factors.

Clinical management of second-generation tyrosine kinase inhibitor therapy in patients with newly diagnosed chronic myeloid leukemia in the chronic phase, focusing on age and dose effects.

ABL1-tyrosine kinase inhibitors (TKIs) are an established treatment choice for patients with chronic myeloid leukemia in the chronic phase (CML-CP). However, effects of TKI dose modification have not been well investigated. In this study, we retrospectively analyzed 178 patients with newly diagnosed CML-CP who were treated with dasatinib or nilotinib, focusing on age and dose effects.

Role of TGF-beta1 and TNF-alpha1 produced by neoplastic cells in the pathogenesis of fibrosis in patients with hematologic neoplasms.

We conducted this study with the objective of elucidating the mechanism of development of fibrosis in hematologic neoplasms and develop treatments for these patients. Among the suggested mechanisms of development of fibrosis is cases of hematologic neoplasms is the production of TGF-beta1 (transforming growth factor-beta-1) and TNF-alpha1 (tumor necrotizing factor-alpha-1) by the tumor cells, both of which are fibrosis-stimulating cytokines that act on fibroblasts to promote fibrosis. However, there are few reports based on human clinical pathology studies.

Management and Risk Factors for Pleural Effusion in Japanese Patients with Chronic Myeloid Leukemia Treated with First-line Dasatinib in Real-world Clinical Practice.

Glycolytic enzyme hexokinase II is a putative therapeutic target in B-cell malignant lymphoma.

Hexokinase II (HXKII) is a key regulator of glucose metabolism that converts glucose to glucose 6-phosphate. Furthermore, HXKII blocks mitochondria-dependent apoptosis by inhibiting the release of cytochrome c. HXKII overexpression is frequently observed in several types of cancer and confers chemoresistance to cancer cells.

Combined Coagulopathy Can Induce Both Hemorrhagic and Thrombotic Complications in Multiple Myeloma.

Coagulation abnormalities are a rare but critical complication associated with plasma cell diseases. We herein present a case of multiple myeloma (MM) with complicated coagulopathy. Initially, the patient showed severe bleeding tendency due to concomitant acquired hemophilia A and acquired von Willebrand syndrome.

Bortezomib maintenance therapy in transplant-ineligible myeloma patients who plateaued after bortezomib-based induction therapy: a multicenter phase II clinical trial.

In the era of novel therapeutic agents for multiple myeloma (MM), both the significance of achieving the plateau phase and the efficacy of subsequent maintenance therapy remain unclear. In the present study, we evaluated the efficacy and safety of bortezomib maintenance therapy (biweekly for 1 year) in transplant-ineligible MM patients who plateaued after bortezomib-based induction therapy. Of 36 evaluable patients, the overall response rate during induction therapy was 61%, with a stringent complete response in 6%, a complete response in 6%, a very good partial response in 17%, and a partial response in 33%.

Tumor Lysis Syndrome after the Administration of Ruxolitinib in a Patient with Post-polycythemia Vera Myelofibrosis.

The development of tumor lysis syndrome (TLS) in association with treatment for myeloproliferative neoplasms (MPNs) is relatively rare. We herein present the case of a post-polycythemia vera (PV) myelofibrosis patient with massive splenomegaly who developed laboratory TLS after treatment with ruxolitinib, a potent JAK1/JAK2 inhibitor. She also exhibited a rapid reduction of spleen volume.

[18F-FDG-PET/CT is effective in distinguishing myelofibrosis due to bone marrow infiltration of diffuse large B-cell lymphoma from triple-negative primary myelofibrosis].

Although myelofibrosis is mainly associated with myeloproliferative neoplasms (MPN), especially primary myelofibrosis (PMF), a variety of hematological malignancies, including acute myeloid leukemia, multiple myeloma and malignant lymphoma, also cause myelofibrosis with markedly varying degrees of severity. Thus, it is extremely important to accurately diagnose the underlying diseases that cause fibrosis in bone marrow. Analyses of JAK2, MPL and calreticulin gene mutations are useful for distinguishing MPN from other diseases, since 90% of MPN patients have a mutation in one of these genes.

A CSF3R T618I Mutation in a Patient with Chronic Neutrophilic Leukemia and Severe Bleeding Complications.

Chronic neutrophilic leukemia (CNL) is a rare form of myeloproliferative neoplasm characterized by the drastic elevation of mature neutrophils. One of the major causes of death among patients with CNL is severe bleeding; however, the difficulty of accurately diagnosing this disease has caused confusion in this field. Recently, somatic mutations of the CSF3R gene have been associated with CNL.

Extranodal NK/T-cell lymphoma, nasal type of the uterine cervix: A case report.

We report a rare case of extranodal NK/T-cell lymphoma, nasal type of the uterine cervix that showed cytologic features mimicking cervical cancer. A 65-year-old woman presented with vaginal bleeding. Gynecological examination revealed a bulky tumor of the cervix.

[Approach to diagnosis and management of myeloproliferative neoplasm variants].

Myeloproliferative neoplasm (MPN) variants are defined as relatively uncommon myeloid neoplasms which do not meet the criteria for either classical MPN or myelodysplastic syndrome. Due to the lack of specific markers, it has been challenging to accurately diagnose these malignant diseases. Recent studies have revealed new genetic abnormalities in MPN variants.
