Cyclophosphamide, bortezomib, and dexamethasone (CyBorD) is highly effective in multiple myeloma. We treated patients with light chain amyloidosis (AL) before stem cell transplantation (ASCT), instead of ASCT in ineligible patients or as salvage. Treatment was a combination of bortezomib (1.5 mg/m2 weekly), cyclophosphamide (300 mg/m2 orally weekly), and(More)
Cereblon (CRBN) mediates immunomodulatory drug (IMiD) action in multiple myeloma (MM). We demonstrate here that no patient with very low CRBN expression responded to IMiD plus dexamethasone therapy. In 53 refractory MM patients treated with pomalidomide and dexamethasone, CRBN levels predict for decreased response rates and significant differences in PFS(More)
IgM multiple myeloma (MM) and Waldenstrom's macroglobulinemia (WM) are two distinct hematologic entities with the common finding of an IgM monoclonal gammopathy. Distinguishing these two diagnoses is critical as the approach to therapy is different. A priori, we defined IgM MM as a symptomatic clonal plasma cell proliferative disorder characterized by an(More)
To determine the effects of the pulmonary hypoplasia present at birth in infants with congenital diaphragmatic hernia upon subsequent development of the lung, 19 patients who had undergone surgical repair before the age of one year were studied at ages 6 to 18 years. Total lung capacity and vital capacity averaged 99% of predicted value. Diffusing capacity(More)
Severe bronchial hemorrhage in 13 patients with cystic fibrosis was treated by catheter embolization of bronchial arteries. Indications were either excessive bleeding persisting for several days, or bleeding serious enough to interfere with pulmonary drainage and recurring over weeks or months. In follow-up ranging from one to 30 months, cessation of major(More)
Donor lymphocyte infusions (DLIs) induce potent graft versus tumor (GVT) effects for relapsed chronic myelogenous leukemia (CML) after allogeneic stem cell transplantation (SCT) but are disappointing for other diseases. Disease resistance can occur if donor T cells are not appropriately activated in vivo. Ex vivo T-cell activation might overcome(More)
We report the clinical and pathologic features of five children wih a botyroid rhabdomyosarcoma of the biliary tract. There were three boys and two girls ranging in age from 11/2 to 51/2 years at diagnosis. Obstructive jaundice was the usual presenting sign, often with fever and hepatomegaly. Of four tumors involving the common bile ducts, two extended into(More)
Polyalveolar lobe is one of the recently described pathological entities that can give rise to congenital lobar emphysema (CLE). In polyalveolar lobe, the total alveolar number as determined by microscopic point-counting of randomly taken lung sections is increased three to fivefold. The airways and arteries are normal for age in number, size and structure.(More)
BACKGROUND Although convincing data exist regarding the prognostic utility of positron emission tomographic (PET)-computed tomographic (CT) imaging in Hodgkin lymphoma and diffuse large B-cell lymphoma, its prognostic utility both during treatment and immediately after treatment have not been systematically evaluated in a large mantle cell lymphoma (MCL)(More)
Sixteen patients, aged 1 month to 15 years, were studied to determine the clinical course and long-term outcome of empyema in previously healthy children. The pathogens responsible were Haemophilus influenzae type b (seven patients), Staphylococcus aureus (five patients), Streptococcus pneumoniae (three patients), and viridans group Streptococcus (one(More)
