Efficacy of eribulin monotherapy for bone marrow carcinomatosis of breast cancer in a patient with Werner syndrome.

Various complications and potential risks of serious adverse events lessens the intensity of chemotherapy in patients with Werner syndrome. Bone marrow carcinomatosis of breast cancer was developed in a patient with Werner syndrome. Eribulin proved well tolerated and effective in improving severe thrombocytopenia, leading to platelet transfusion-free status.

FLT3 inhibitors and hematopoietic cell transplantation prolong survival in patients with FLT3-ITD-positive AML.

Acute myeloid leukemia (AML) is an aggressive hematological malignancy with genetic alterations. The FMS-like tyrosine kinase 3 (FLT3) gene is frequently mutated in adult de novo AML, with two types of mutations: internal tandem duplication (ITD) and point mutations in the tyrosine kinase domain. This study aimed to investigate the impact of FLT3 inhibitors and hematopoietic cell transplantation (HCT) on survival outcomes in patients with FLT3-ITD AML in a real-world setting.

Novel method for assessing sinusoidal obstruction syndrome using four-dimensional computed tomography.

Introduction: To diagnose sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD), transabdominal ultrasonography is usually used to detect hemodynamic changes, but we tried to detect the changes using four-dimensional computed tomography (4D-CT). A 42-year-old Japanese woman was diagnosed with late-onset SOS/VOD with transabdominal ultrasonography and was also assessed using 4D-CT. Method We analyzed the portal vein (PV) contrast effect every 1.

Successful Treatment With Venetoclax Plus Azacytidine Combined With Radiation Therapy and Donor Lymphocyte Infusion in a Patient With Extramedullary Relapse of Acute Myeloid Leukemia After Stem Cell Transplantation.

Extramedullary (EM) relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia (AML) is rare and causes systemic relapse. Consequently, the prognosis is very poor because limited treatment is feasible in post-transplant patients. The efficacy and safety of venetoclax (VEN), a newly developed oral inhibitor of B-cell leukemia/lymphoma-2, plus azacytidine (AZA) in patients newly diagnosed with AML who are ineligible for intensive chemotherapy have been reported.

Acute Abdomen and Adrenal Swelling as the First Manifestations of TAFRO Syndrome.

TAFRO syndrome, a rare systemic inflammatory disorder, commonly develops in an acute or subacute manner, with an aggressive clinical behavior. A substantial number of cases of TAFRO syndrome presenting with abdominal pain, and adrenal abnormalities on imaging have also been reported. A 54-year-old man developed severe acute abdominal pain.

Primary cutaneous diffuse large B-cell lymphoma, leg type, in a patient with rheumatoid arthritis undergoing etanercept therapy.

An 84-year-old woman, who was diagnosed with rheumatoid arthritis (RA) and was treated with methotrexate and, subsequently, etanercept (ETN) for 6 years, presented with rapidly progressing painful cutaneous mass on the right medial malleolus. The patient was eventually diagnosed with primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL-LT). ETN therapy was promptly discontinued expecting spontaneous regression of the lymphoma, which was thought to have developed as other iatrogenic immunodeficiency-associated lymphoproliferative disorders.

Gastrointestinal Stromal Tumor in a Patient with Neurofibromatosis Type 1 That Was Successfully Treated with Regorafenib.

An unconscious 55-year-old man with a history of neurofibromatosis type 1 (NF1) was transported to the emergency department and was diagnosed with acute renal failure owing to a large bladder tumor. A submucosal tumor was also identified in the duodenum. The patient was diagnosed with a primary gastrointestinal stromal tumor (GIST) of the bladder and duodenum.

Morphological Transformation of Myeloma Cells into Multilobated Plasma Cell Nuclei within 7 Days in a Case of Secondary Plasma Cell Leukemia That Finally Transformed as Anaplastic Myeloma.

A 48-year-old man was diagnosed with multiple myeloma (IgG-k) and was treated with high-dose dexamethasone as an induction therapy followed by thalidomide-based regimens. Approximately 22 months after the initial diagnosis, the patient developed secondary plasma cell leukemia (PCL) with a white blood cell (WBC) count of 20.2 × 10/L including 79.

A phase II trial of small-dose bortezomib, lenalidomide and dexamethasone (sVRD) as consolidation/maintenance therapy in patients with multiple myeloma.

Purpose: Consolidation/maintenance therapy induces deep remission in patients with multiple myeloma (MM); however, the most suitable regimen has been under investigation. The combination therapy with bortezomib, lenalidomide and dexamethasone (VRD) is a powerful regimen for relapsed/refractory as well as newly diagnosed MM as an induction therapy. However, severe adverse events (AEs) may become a problem when VRD is introduced without dose reduction as a consolidation/maintenance therapy.

Pneumatosis intestinalis during chemotherapy with nilotinib in a patient with chronic myeloid leukemia who tested positive for anti-topoisomerase I antibodies.

A 55-year-old man with several comorbidities including idiopathic interstitial pneumonia under long-term corticosteroid therapy, longstanding myocardial infarction, chronic heart failure, paroxysmal atrial fibrillation, gastro-esophageal reflux disease, constipation, and history of paralytic ileus, was diagnosed with chronic myelogenous leukemia (CML) in the chronic phase. He also tested positive for anti-topoisomerase I antibodies without clinical diagnosis of any connective tissue disease, including systemic sclerosis. Approximately 5 months after the initiation of nilotinib for CML, he developed upper abdominal distension with intermitting abdominal pain, and based on abdominal computed tomography findings, a diagnosis of pneumatosis intestinalis (PI) was made.

Thrombocytopenia and Anemia with Anti-c-Mpl antibodies Effectively Treated with Cyclosporine in a Patient with Rheumatoid Arthritis and Chronic Renal Failure.

A 61-year-old woman with rheumatoid arthritis who was undergoing hemodialysis for end-stage renal failure was transferred to our hospital due to severe thrombocytopenia and anemia. A bone marrow biopsy showed the complete absence of megakaryocytes and erythroblasts. Cyclosporine treatment resulted in the improvement of her megakaryocyte and erythroblast levels, and a decrease in her serum level of anti-c-Mpl (thrombopoietin receptor) antibodies.

[Langerhans cell sarcoma developing acute myeloid leukemia after achieving complete response by THP-COP].

An 86-year-old man presented with enlarged left submandibular, left inguinal, and superficial femoral lymph nodes. He was diagnosed with Langerhans cell sarcoma (LCS) on the basis of the histopathological findings of the left inguinal lymph node biopsy. In addition, laboratory examinations revealed normocytic normochromic anemia, and bone marrow aspiration and biopsy led to a diagnosis of idiopathic cytopenia of undetermined significance (ICUS).

Identification of anti-thrombopoietin receptor antibody in prolonged thrombocytopenia after allogeneic hematopoietic stem cell transplantation treated successfully with eltrombopag.

A 55-year-old female with stage IVA follicular lymphoma in third complete remission underwent allogeneic peripheral blood stem cell transplantation. Neutrophil engraftment was achieved on day +18; however, platelet counts remained below 10 × 10(3)/µL, necessitating transfusions twice a week for more than 3 months. Bone marrow showed a decreased number of megakaryocytes with hypolobulated nuclei.

Effect of duloxetine in Japanese patients with chemotherapy-induced peripheral neuropathy: a pilot randomized trial.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is difficult to manage. A phase III trial conducted in the United States demonstrated that duloxetine was effective for CIPN caused by taxane and platinum-based chemotherapy. No randomized trial of duloxetine for CIPN has been conducted in Japan.
