We studied clinical features and pathologic findings in 52 consecutively autopsied patients with multiple myeloma in our center between 1979 and 1998. Distant extraosseous involvement was found in 33 patients (63.5%). Thirty-one patients (59.6%) were proven to have infection at autopsy, among which pneumonia was most common site of infection. Amyloidosis(More)
Flow cytometry (FC) is widely utilized in the diagnosis of lymphoma and the light chain ratio (LCR) is especially useful in the diagnosis of B-cell malignancy. In this study we analysed, retrospectively, the predictive value of the LCR in the diagnosis of B-cell lymphoma in 105 consecutive patients with persistent lymph node enlargement or extranodal masses(More)
BACKGROUND Fluconazole is used widely for fungal prophylaxis. Although studies with bone marrow transplantation (BMT) recipients clearly showed the usefulness of oral fluconazole, results of the studies in neutropenic patients other than BMT recipients have been inconsistent. Therefore, the authors performed a meta-analysis to evaluate the efficacy of(More)
Interleukin 2 receptor is expressed not only on the surface of activated T or B lymphocytes, but also on certain lymphoid malignancies. The receptor is released from the cell membrane as soluble form (sIL-2R). Serum sIL-2R level is a sensitive and quantitative marker of circulating peripheral blood mononuclear cell activation or specific tumor cell growth(More)
Bone marrow transplant (BMT) recipients have risk factors for deep vein thrombosis (DVT) including venous stasis caused by immobilization in the sterile unit, vessel wall damage caused by preparative regimen or indwelling catheters, and hypercoagulability caused by decreased natural anticoagulants. We successfully treated a patient who developed massive DVT(More)
C-reactive protein (CRP) is an acute phase reactant of inflammation. We evaluated the clinical value of serial measurement of CRP in neutropenic patients. CRP was shown to be useful to monitor the response to therapy for febrile episodes in neutropenia. However, we failed to show statistically significant differences in CRP levels between febrile episodes(More)
Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal B-cell neoplasm occurring most frequently in the stomach. The majority of gastric MALT lymphomas regress after Helicobacter pylori eradication therapy, and its development is considered to be closely associated with H. pylori infection. A few recent studies have reported on such regression(More)
BACKGROUND Although many studies have been performed to evaluate the prognostic significance of CD34 expression in acute myeloid leukemia (AML), the findings have been inconsistent. In this study, the authors reviewed such previous studies to establish a definite conclusion. METHODS Using MEDLINE, the authors identified studies that evaluated the(More)
We evaluated possible prognostic factors just before salvage therapy with vincristine, doxorubicin, and dexamethasone (VAD) for 36 patients with refractory multiple myeloma. The median duration from diagnosis to the first VAD salvage was 14 months (range 2-76 months). Among parameters that have been shown to be associated with poor survival, a high serum(More)
Cyclophosphamide (CPA) is widely used for peripheral blood stem cell mobilization, and a dose adjustment of CPA in the presence of renal failure has not been suggested. However, we describe a myeloma patient with renal failure (serum creatinine 4.2 mg/dl, creatinine clearance 11.2 ml/min) receiving CPA 2 g/m2 for 2 days, who developed unexpectedly severe(More)
