Cyclin-dependent kinase 9 (CDK9), a subunit of the positive transcription elongation factor b (P-TEFb) complex, regulates gene transcription elongation by phosphorylating the carboxy-terminal domain (CTD) of RNA polymerase II (RNAPII).  The deregulation of CDK9/P-TEFb has important implications for many cancer types.  BAY 1143572 is a novel and highly selective CDK9/P-TEFb inhibitor currently being investigated in phase I studies. We evaluated the therapeutic potential of BAY 1143572 in adult T-cell leukemia/lymphoma (ATL)...

Purpose T-cell-replete HLA-haploidentical donor hematopoietic transplantation using post-transplant cyclophosphamide was originally described using bone marrow (BM). With increasing use of mobilized peripheral blood (PB), we compared transplant outcomes after PB and BM transplants. Patients and Methods A total of 681 patients with hematologic malignancy who underwent transplantation in the United States between 2009 and 2014 received BM (n = 481) or PB (n = 190) grafts. Cox regression models were built to examine differences in transplant outcomes by graft type, adjusting for patient, disease, and transplant characteristics...

A 35-year-old woman with biopsy-proven recurrent Hodgkin lymphoma in the neck lymph nodes received salvage chemotherapy of brentuximab/insulin growth factor-methotrexate. Although the patient continued doing well clinically with no constitutional symptoms or significant laboratory abnormalities following the second recurrence, subsequent FDG PET CT examinations over the next 2 years revealed multiple new FDG-avid foci including lymph nodes above/below the diaphragm, liver, spleen, lungs, and bone. An alternate diagnosis of chemotherapy-induced sarcoidosis was suggested and confirmed on both bone marrow and right inguinal node biopsy...

Composite lymphoma is a rare tumor composed of two or more distinct lymphomas in the same topographic site or tissue. Several combinations of B-cell non-Hodgkin lymphoma (NHL), T-cell NHL, and Hodgkin lymphoma can occur with different prognoses and treatments. The coexistence of a B-cell NHL and a T-cell NHL is unusual. The exact etiology of composite lymphoma is unknown; however, few mechanisms have been proposed to explain its pathogenesis. The chemotherapeutic protocols are heterogeneous but are essentially targeted against the high-grade component...

Bone loss occurs frequently following allogeneic haematopoietic stem cell transplantation (alloSCT). The Australasian Leukaemia and Lymphoma Group conducted a prospective phase II study of pretransplant zoledronic acid (ZA) and individualised post-transplant ZA to prevent bone loss in alloSCT recipients. Patients received ZA 4 mg before conditioning. Administration of post-transplant ZA from days 100 to 365 post alloSCT was determined by a risk-adapted algorithm based on serial bone density assessments and glucocorticoid exposure...

Osteosarcoma is the most common primary malignant bone tumor. Cancer cells employ a host of mechanisms to develop resistance to adriamycin (ADM) or other chemotherapeutic drugs. Shikonin (SK), an active constituent extracted from a Chinese medicinal herb, has been shown to cooperate with ADM in the treatment of osteosarcoma and certain other types of cancer by contributing to the response rate of chemotherapy and the side effects. The aim of the present study was to investigate the role and underlying mechanism of SK in chemotherapy for osteosarcoma...

Anaplastic large cell lymphoma (ALCL) is a CD30+ T-cell non-Hodgkin lymphoma with two main clinical presentations: primary cutaneous (pcALCL) and systemic (sALCL). While rare cases of myxoid sALCL have been reported, there are no previous cases of myxoid pcALCL reported. We present two unusual cases of pcALCL showing prominent collections of dermal mucin closely intermingling with the anaplastic lymphocytes. Patient 1 was a 30-year-old woman who presented with ulcerated nodules on her neck, abdomen, chest, and shoulders...

We herein report a rare case of miliary tuberculosis-associated hemophagocytic syndrome (HPS) complicated with respiratory failure. A 19-year-old Japanese woman with a fever, general malaise, and chest radiograph abnormalities was referred to our hospital. After admission, she developed respiratory failure with pancytopenia. A histological examination of lung and bone marrow biopsy samples revealed noncaseating granulomas without evidence of acid-fast bacilli or lymphoma. In addition, a bone marrow biopsy showed marked histiocyte hyperplasia with hemophagocytosis, and a bronchoalveolar lavage fluid culture grew Mycobacterium tuberculosis...

BACKGROUND: We present a case of gamma-delta T-cell lymphoma that does not fit the current World Health Organization classifications. CASE PRESENTATION: A 74-year-old Caribbean-American woman presented with lymphocytosis, pruritus, and non-drenching night sweats. Bone marrow and peripheral blood analyses both confirmed the diagnosis of gamma-delta T-cell lymphoma. An axillary lymph node biopsy was negative for lymphoma. Clinically absent hepatosplenomegaly and skin lesions with biopsy-proven gamma-delta T-cell lymphoma suggest that she is unclassifiable within the current classification system...

BACKGROUND: Proximal end of the humerus is a common site for both primary and metastatic bone tumors. Limb salvage with endoprosthetic replacement is the most common means of reconstruction, but it has been proved that cement spacer are more beneficial for inferior shoulder function. Thus, limb salvage can be replaced by cheaper spacers especially in poor societies. PATIENTS AND METHODS: This study included 20 patients, of whom 14 were female, with a mean age of 40...

Neck pain is a common reason for seeking medical attention. It affects at least 15% of the labor force and up to 40% of individuals whose occupation is hazardous. On the other hand, primary bone lymphoma is a very rare disease (less than 1% of all malignant bone tumors), and the relationship between the 2 has rarely been mentioned. We report the case of a patient who had a 1-month history of neck pain. The main symptom was pain on palpation of C2-C6 cervical spinous processes and contracture of the trapezius muscle that did not cease with conventional treatment...

BACKGROUND: The regulation of erythropoiesis involves hematopoietic progenitor cells, bone marrow stroma, and the microenvironment. Following severe injury, a hypercatecholamine state develops that is associated with increased mobilization of hematopoietic progenitor cells to peripheral blood and decreased growth of bone marrow erythroid progenitor cells that manifests clinically as a persistent injury-associated anemia. Changes within the bone marrow microenvironment influence the development of erythroid progenitor cells...
