BACKGROUND Malignant lymphoma with central nervous system (CNS) involvement has an extremely poor prognosis. We retrospectively studied the risk factors for CNS involvement in patients with diffuse large B-cell lymphoma (DLBCL) treated by cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or rituximab (R) -CHOP chemotherapy. PATIENTS AND(More)
In early gastric cancer, lymph node metastasis is known to be a prognostic factor. A retrospective study of 134 patients with submucosal gastric cancer (SMGC) who had undergone gastrectomy with lymph node dissection was performed to evaluate the prognostic factors and indication of postoperative chemotherapy. Five-year disease-free survival rate for 121(More)
The maximum standard uptake value (SUVmax) of the whole body on 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) reflects the tumor aggressiveness in non-Hodgkin lymphoma (NHL). To clarify the correlation between SUVmax at the biopsy site and the proliferation potential of tumor cells, we studied 36 patients with untreated NHL and five with(More)
This study evaluated the efficacy of central nervous system (CNS) prophylaxis using intrathecal methotrexate (IT-MTX) in patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively studied 322 patients who achieved first complete remission (CR) after rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. The(More)
OBJECTIVES Platelet activation, which may lead to thrombus formation, is poorly understood after valve surgery when analysed by flow cytometry. It is still unclear whether platelet activation is due to the implanted prosthesis itself or to its aortic or mitral position. The present prospective study was aimed at assessing platelet P-selectin expression,(More)
We retrospectively studied the association between iron overload and bloodstream infections (BSI) in the 100-day period following allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia or myelodysplastic syndromes. Serum ferritin was measured before transplantation to evaluate iron overload. Of 114 adult patients who(More)
Hospital cleanliness in hospitals with a tendency toward long-term care in Japan remains unevaluated. We therefore visualized hospital cleanliness in Japan over a 2-month period by two distinct popular methods: ATP bioluminescence (ATP method) and the standard stamp agar method (stamp method). The surfaces of 752 sites within nurse and patient areas in(More)
The levels of serum beta-2 microglobulin (β2MG) are determined mainly from lymphoid tissue. To examine its prognostic value in Hodgkin lymphoma (HL), we conducted a retrospective analysis. We analyzed 67 patients with HL diagnosed and treated at seven institutes of the Yokohama City University Hematology Group between 1998 and 2011. The patients included 40(More)
The prognostic implications of infra-diaphragmatic (InD) versus supra-diaphragmatic (SpD) primary lesions in limited-stage diffuse large B-cell lymphoma (DLBCL) remains unknown. This retrospective study aimed to assess the prognostic impact of spD and InD lesions as well as presence of gastrointestinal (GI) involvements in adults with limited-stage DLBCL.(More)
Central nervous system (CNS) events, including CNS relapse and progression to CNS, are known to be serious complications in the clinical course of patients with lymphoma. This study aimed to evaluate the risk of CNS events in patients with diffuse large B-cell lymphoma in the rituximab era. We performed a retrospective survey of Japanese patients diagnosed(More)
