Obinutuzumab is a novel glycoengineered Type-II CD20 monoclonal antibody. CD20 is expressed in approximately 100% of children and adolescents with Burkitt lymphoma (BL) and 40% with precursor B-cell acute lymphoblastic leukaemia (pre-B-ALL). We evaluated the anti-tumour activity of obinutuzumab versus rituximab against rituximab-resistant (Raji 4RH) and(More)
BACKGROUND & AIMS Microparticles are small membrane vesicles released from the cell plasma membrane, particularly in cell stress, apoptosis and altered cellular viability. Hepatocellular carcinoma (HCC) is a hypervascular neoplasm with high levels of apoptosis and necrosis. We investigated the levels of circulating microparticles of both tumor and(More)
BACKGROUND/AIMS The authors reviewed their experience with resected IPMT (intraductal papillary-mucinous tumor) of the pancreas to clarify the characteristics and prognosis of this neoplasm. METHODOLOGY Between 1983 and 1998, 30 consecutive patients with IPMT underwent operations at our institution. Their clinicopathological features and postoperative(More)
BACKGROUND/AIMS Multiple genetic alterations are involved in the development of pancreatic neoplasm. Here we investigated the incidence of p53, ras, bcl-2 and c-erbB-2 gene alterations in intraductal papillary-mucinous tumors and invasive ductal adenocarcinoma of the pancreas by immunohistochemical method to identify and analyze their relationship in terms(More)
BACKGROUND/AIMS In this study we investigated the expressions of molecular biologic factors, p53, rasp21, bcl-2, c-erbB-2, and Ki-67 by immunohistochemical method in intraductal papillary-mucinous tumor of the pancreas to identify their diagnostic values and to determine their relations to the degree of histopathologic abnormalities. METHODOLOGY(More)
Therapy-related acute myeloid leukemia (AML) is a long term complication of chemotherapy for a variety of cancers. In most cases, the marrow demonstrates high risk cytogenetics and the prognosis is poor. In a minority of patients "good risk" cytogenetics, including t(15;17)(q22;q12), are seen and the patient's prognosis is similar to those who have de novo(More)
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, with about 30% of new cases presenting with extranodal disease. Lesions originating from soft tissues of the upper extremities are extremely rare and may mimic other malignancies like sarcoma. We present a case of an elderly patient with right upper extremity (RUE) mass(More)
Epstein-Barr virus (EBV) associated smooth muscle tumors (SMTs) have been described in patients with acquired immune deficiency syndrome (AIDS) and, more recently, in association with immunosuppression after solid-organ transplantation. We present the autopsy findings of multiple leiomyosarcomas (LMSs) in a 24-year old man who died 18 months after(More)
