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 graft sources on immune reconstitution and survival outcomes following allogeneic stem cell transplantation.

We evaluated the kinetics of immune reconstitution (IR) after allogeneic hematopoietic cell transplantation (HSCT) and analyzed the clinical effect of IR on posttransplant outcomes. Absolute lymphocyte and its subset counts were measured using flow cytometry on days 28, 100, 180, 365, and 730 after transplantation in 358 adult patients who underwent HSCT between 2009 and 2017. On day 100 after HSCT, 310 surviving patients were analyzed.

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.

Clinical Significance of Serum Ferritin at Diagnosis in Patients With Acute Myeloid Leukemia: A YACHT Multicenter Retrospective Study.

Purpose: A multicenter retrospective analysis was performed to evaluate the clinical significance of serum ferritin at diagnosis in patients with acute myeloid leukemia (AML).

Methods: The study cohort included 305 patients who were newly diagnosed with AML from 2000 to 2015 and received standard induction chemotherapy. Transplantation was performed in 168 patients.

Body mass index is a prognostic factor in adult patients with acute myeloid leukemia.

Body mass index (BMI), which represents the proportion of weight to height, is a controversial prognostic factor for acute myeloid leukemia (AML). We evaluated prognostic value of BMI in Japanese AML. The study included 369 adult patients with newly diagnosed AML who were administered either daunorubicin or idarubicin with cytarabine as induction chemotherapy.

Outcome and prognostic factors among patients who underwent a second transplantation for disease relapse post the first allogeneic cell transplantation.

The prognosis for disease relapse after first hematopoietic cell transplantation (HCT1) is poor. Here, we present a retrospective multicenter study to evaluate the clinical outcome and the prognostic factors for second hematopoietic cell transplantation (HCT2). The cohort in this study comprised 60 patients diagnosed with acute leukemia, who underwent HCT2 due to hematological relapse after HCT1.

Hyper-recovery of platelets after induction therapy is a predictor of relapse-free survival in acute myeloid leukemia.

We verified the association between standard clinical and laboratory variables and the risk of relapse in acute myeloid leukemia (AML), which led us to retrospectively examine the effect of regeneration of hematopoiesis in patients with newly diagnosed AML. We used data from 230 patients who obtained remission after cytarabine-based induction chemotherapy. Platelet counts ≥500 × 10/L and hemoglobin levels ≥9 g/dL on day 28 after treatment initiation were significantly associated with relapse-free survival (RFS) rate, conferring respective multivariate risk ratios of 0.

Retrospective Study of Incidence and Prognostic Significance of Eosinophilia after Allogeneic Hematopoietic Stem Cell Transplantation: Influence of Corticosteroid Therapy.

Objective: The clinical significance of eosinophilia after allogeneic hematopoietic stem cell transplantation is controversial. This study aimed to retrospectively study the impact of eosinophilia on the outcome of allogeneic hematopoietic stem cell transplantation by taking into account the influence of corticosteroid therapy.

Materials And Methods: We retrospectively studied 204 patients with acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome who underwent allogeneic hematopoietic stem cell transplantation from January 2001 to December 2010.

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).

Predictive value of risk assessment scores in patients with hematologic malignancies undergoing reduced-intensity conditioning allogeneic stem cell transplantation.

Reduced-intensity conditioning allogeneic stem cell transplantation (RIC allo-SCT) is associated with less toxicity and is used for older patients. We retrospectively studied the predictive value of two risk assessment scores, which were the hematopoietic cell transplantation-specific comorbidity index (HCT-CI) and the pre-transplantation assessment of mortality (PAM) score, for assessing the outcome of RIC allo-SCT. Seventy-eight patients underwent transplantation between 2005 and 2013 at a single institution.

Human herpesvirus-6 encephalopathy after hematopoietic stem cell transplantation and class I human leukocyte antigen.

Human herpesvirus-6 (HHV-6) encephalopathy is a serious complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although reactivation of HHV-6 is often observed after allo-HSCT, encephalopathy only affects a few patients with HHV-6 reactivation. Human leukocyte antigen (HLA) class I is expressed by most somatic cells, and a relationship between some class I alleles and neurological diseases has been reported.

Prognostic index for relapsed acute leukemia after allogeneic stem cell transplant.

We retrospectively studied patients who relapsed after allogeneic stem cell transplantation (SCT) to identify factors influencing outcomes. Of the 296 patients (196 with AML and 100 with ALL), 102 (34%) experienced relapse at a median of 222 days (range: 30-2,748) after SCT. Multivariable analysis showed that high disease risk (hazard risk [HR]: 1.

Recovery of natural killer cells and prognosis after cord blood transplantation.

The relationship between immune reconstitution and the prognosis after cord blood transplantation is unclear. We investigated the influence of natural killer (NK) cell recovery on transplant outcomes. The maximum number of CD56+CD3- cells or CD57+CD16+ cells was determined to assess NK recovery.

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.

Lymphocyte recovery on day 100 after allogeneic hematopoietic stem cell transplant predicts non-relapse mortality in patients with acute leukemia or myelodysplastic syndrome.

Abstract To clarify the clinical significance of lymphocyte recovery on day 100 after allogeneic hematopoietic stem cell transplant (allo-HSCT), we retrospectively studied 157 patients with hematologic malignancies who underwent allo-HSCT. An absolute lymphocyte count < 500/μL was defined as lymphocytopenia. There was a significant relationship between lymphocytopenia and advanced disease at allo-HSCT or corticosteroid administration within 100 days.

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.

[POEMS syndrome treated with lenalidomide plus high-dose dexamethasone as a pre-transplant induction therapy].

A 60-year-old male with POEMS syndrome received lenalidomide and high-dose dexamethasone combination therapy as an initial treatment, with no severe adverse events occurring during the treatment. Two cycles of the therapy led to significantly decreased serum VEGF level, and IgA-λ type M-protein was not detected by immunofixation electrophoresis. We next performed autologous stem cell transplantation, without severe complications such as engraftment syndrome.

Clinical features of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue.

We newly diagnosed 131 patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue lymphoma between 1998 and 2010. We retrospectively studied 124 patients for whom complete clinical data were available at presentation and who had minimally undergone tumour staging by physical examination, computed tomography (CT), bone marrow aspiration, and biopsy. A slight female predominance (men, 58; women, 66) was observed in the study population; the median age was 67 years.

Clinical manifestations of primary pulmonary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue in Japanese population.

We retrospectively analysed 16 cases of newly diagnosed pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma in the Japanese population. The disease was found on the basis of examination findings in 14 cases, and clinical manifestations in 2. According to the extensive staging procedure, four patients had concomitant gastric involvement.
