Clinical impact of cigarette smoking on the outcomes of allogeneic hematopoietic stem cell transplantation: a multicenter retrospective study.

Smoking is associated with a high risk for different diseases including respiratory tract infections in immunocompetent patients. However, data about the effects of cigarette smoking on the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) are limited. Therefore, we retrospectively investigated 608 patients aged ≥20 years with hematological disorders who received their first allo-HSCT at our group of hospitals between 2000 and 2015, and evaluated the impact of cigarette smoking before allo-HSCT on clinical outcomes by dividing patients into two groups according to the Brinkman index (BI) (nonsmokers or light smokers [BI: 0-500] and heavy smokers [BI: ≥ 500]).

[Successful child delivery in treatment-free remission of chronic myeloid leukemia after discontinuation of dasatinib].

A 21-year-old woman was diagnosed with chronic myeloid leukemia in March 2014. The patient and her family did not wish to freeze eggs before dasatinib initiation. After 66 months of oral dasatinib administration and 40 months of MR4.

Comparison of Clinical Features Between Primary and Secondary Breast Diffuse Large B Cell Lymphoma: A Yokohama Cooperative Study Group for Hematology Multicenter Retrospective Study.

We performed a retrospective analysis of DLBCL with breast involvement to compare the prognosis of primary breast lymphoma (PBL) to secondary breast lymphoma (SBL; especially in limited stage cases). We retrospectively reviewed records of 25 diffuse large B-cell lymphoma (DLBCL) patients with breast involvement who received chemotherapy between January 2000 and August 2012. We compared clinical features and prognosis among patients with PBL ( = 11), limited stage SBL (LSBL;  = 6), and advanced stage SBL (ASBL,  = 8).

Computed tomography-defined sarcopenia: prognostic predictor of nonrelapse mortality after allogeneic hematopoietic stem cell transplantation: a multicenter retrospective study.

We analyzed clinical cutoffs for defining computed tomography (CT) methods for sarcopenia and examined the prognostic value of CT for allogeneic hematopoietic stem cell transplantation (allo-HCST) outcomes of patients with myeloid malignancy. One hundred twenty-five adult patients with acute myeloid leukemia and myelodysplastic syndrome who underwent first allo-HSCT between 2000 and 2017 were included. Sarcopenia was assessed using CT-based skeletal muscle index (SMI) and mean muscle attenuation at L3.

Impact of treatment-related weight changes from diagnosis to hematopoietic stem-cell transplantation on clinical outcome of acute myeloid leukemia.

We hypothesized that treatment-related weight loss is associated with worse outcomes following HSCT. Overall, 184 patients with AML who underwent induction therapy were classified according to d-BMI (BMI at transplant minus BMI at diagnosis) (kg/m) as < -2, - 2 to + 2, and > + 2. At 1 year, OS was 67.

[Successful induction therapy for acute myeloid leukemia complicated with brain hemorrhage and hyperleukocytosis].

Adequate management of hyperleukocytosis in patients with acute myeloid leukemia (AML) is essential for the prevention of life-threatening complications related to leukostasis and tumor lysis syndrome, but the optimal therapeutic strategy remains unclear. We report a 15-year-old girl with newly diagnosed AML who had extreme hyperleukocytosis (leukocyte count at diagnosis, 733,000/μl) leading to a brain hemorrhage. She was initially treated with hydroxyurea, but presented with brain hemorrhage due to leukostasis and underwent leukapheresis emergently with intensive care and mechanical ventilation.

Efficacy and safety of a 5-day regimen of azacitidine for patients with high-risk myelodysplastic syndromes.

Although a 7-day (d) regimen of azacitidine (AZA) is the standard treatment of high-risk myelodysplastic syndromes (MDS), AZA is difficult to administer during weekends in an outpatient setting. We retrospectively investigated the outcome of a 5-d regimen of AZA in patients with high-risk MDS. High-risk MDS was defined as MDS with intermediate-2- or high-risk MDS according to the International Prognostic Scoring System.

Beta-2 microglobulin is a strong prognostic factor in patients with DLBCL receiving R-CHOP therapy.

Useful prognostic markers for patients with diffuse large B cell lymphoma (DLBCL) have been reported. To identify which biomarker best predicts the prognosis of patients with DLBCL, we performed a retrospective study that included 319 DLBCL patients who had received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) therapy between 2003 and 2012. We assessed the prognostic significance of six biomarkers [lactate dehydrogenase, soluble interleukin-2 receptor, thymidine kinase activity, beta-2 microglobulin (B2M), C-reactive protein, and ferritin] and representative clinical characteristics using progression-free survival (PFS) as the endpoint.

R-CHOP therapy alone for limited-stage follicular lymphoma.

Irradiation therapy alone is a standard strategy for limited-stage FL, leading to a 10-year progression-free survival (PFS) rate of 30-50%. However, we have been administering R-CHOP therapy alone to patients with limited-stage FL. A total of 35 patients with newly diagnosed FL received R-CHOP therapy with curative intent between 2002 and 2009.

Analysis of outcomes in patients with supra-diaphragmatic vs infra-diaphragmatic diffuse large B cell lymphoma treated with R-CHOP therapy.

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. We analyzed data from 178 patients with limited-stage DLBCL who were treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone therapy at 7 institutions of the Yokohama City University Hematology Group between 2003 and 2009.

Serum ferritin level is prognostic of patient outcome in extranodal NK/T cell lymphoma, nasal type.

The objective of the current study was to assess the prognostic factors in patients with extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKL). We retrospectively analyzed 35 patients who were diagnosed with ENKL between 1998 and 2011. The median patient age was 63 years, and the male/female ratio was 22:13; twenty patients had localized ENKL, and 26 had a good Eastern Cooperative Oncology Group performance status (score 0 or 1).

Peripheral blood absolute lymphocyte/monocyte ratio as a useful prognostic factor in diffuse large B-cell lymphoma in the rituximab era.

Objectives: The tumor microenvironment, including tumor-infiltrating lymphocytes and myeloid-derived cells, is an important factor in the pathogenesis and clinical behavior of malignant lymphoma. However, the prognostic significance of peripheral lymphocytes and monocytes in lymphoma remains unclear.

Methods: We evaluated the prognostic impact of the absolute lymphocyte count (ALC), absolute monocyte count (AMC), and lymphocyte/monocyte ratio (LMR) in 359 diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).

The transcription factor IRF8 counteracts BCR-ABL to rescue dendritic cell development in chronic myelogenous leukemia.

BCR-ABL tyrosine kinase inhibitors (TKI) have dramatically improved therapy for chronic myelogenous leukemia (CML). However, several problems leading to TKI resistance still impede a complete cure of this disease. IFN regulatory factor-8 (IRF8) is a transcription factor essential for the development and functions of immune cells, including dendritic cells.

MIB-1 labeling index as a prognostic factor for patients with follicular lymphoma treated with rituximab plus CHOP therapy.

The MIB-1 labeling index, which is based on Ki67 immunostaining, is widely used to evaluate the proliferation of tumor cells in lymphoma. However, its clinical significance has not been fully assessed. We retrospectively evaluated the prognostic impact of the MIB-1 labeling index at the time of diagnosis, in 98 patients with follicular lymphoma (FL) grade 1-3b who were treated uniformly with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) therapy.

Standard R-CHOP therapy in follicular lymphoma and diffuse large B-cell lymphoma.

The introduction of rituximab (R) has measurably improved the outcome of patients with follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). To evaluate the outcome of patients with FL and DLBCL under R plus CHOP therapy, we performed a retrospective analysis in Yokohama City University Hematology Group in Japan. Five hundred and twenty-six patients (158, FL ; 368, DLBCL) were scheduled to undergo primary therapy with 6 cycles of full-dose R-CHOP therapy with curative intent.

Absolute monocyte count in follicular lymphoma patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone.

Elevated absolute monocyte counts (AMCs) have been reported to indicate poor prognosis for patients with lymphoproliferative disease, including those with follicular lymphoma (FL) receiving various treatments. We evaluated the prognostic impact of AMC in 150 consecutive FL patients who received rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. Progression-free survival (PFS) did not differ significantly according to the AMC level.

[Chronic myeloid leukemia maintained major molecular response with intermittent dosage of imatinib mesylate].

A 57-year-old woman was diagnosed as in the chronic myeloid leukemia-chronic phase. Imatinib mesylate(IM)was initiated at 400 mg daily. She achieved complete cytogenetic response at 3 months, and major molecular response at 10 months.

R-CHOP therapy alone in limited stage diffuse large B-cell lymphoma.

Long-term observation has identified a pattern of continuing relapse in limited stage diffuse large B-cell lymphoma (DLBCL) treated by three cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) plus involved-field irradiation. We retrospectively analysed 190 untreated patients with limited stage DLBCL treated by R-CHOP alone. All the patients were scheduled to undergo primary therapy with six cycles of full-dose R-CHOP.

Primary hepatic peripheral T-cell lymphoma treated with corticosteroid.

Primary hepatic lymphoma is a very rare condition, and the majority of the cases reported are of B-cell origin. We report a case of a 65-year-old man with primary hepatic peripheral T-cell lymphoma, not otherwise specified (PTCL-nos) who presented with 15% weight loss and general fatigue over the previous 9 months. Imaging studies and bone marrow examination could not confirm a diagnosis of lymphoma.
