Treatments and prognostic factors for bone and soft tissue sarcoma in non-urban areas in Japan. Int J Clin Oncol 2024; 29:345-353. [PMID: 38155238 DOI: 10.1007/s10147-023-02453-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 12/05/2023] [Indexed: 12/30/2023]
Abstract
BACKGROUND Although bone and soft tissue sarcoma is recognized as a rare cancer that originates throughout the body, few comprehensive reports regarding it have been published in Japan. PATIENTS AND METHODS Bone and soft tissue sarcomas were tabulated from the Cancer Registries at eight university hospitals in the Chugoku-Shikoku region. Prognostic factors in cases were extracted in a single facility and have been analyzed. RESULTS From 2016 to 2019, 3.4 patients with bone and soft tissue sarcomas per a general population of 100,000 were treated at eight university hospitals. The number of patients who underwent multidisciplinary treatment involving collaboration among multiple clinical departments has been increasing recently. In the analysis carried out at a single institute (Ehime University Hospital), a total of 127 patients (male/female: 54/73) with an average age of 67.0 y (median 69.5) were treated for four years, with a 5-year survival rate of 55.0%. In the analysis of prognostic factors by multivariate, disease stage and its relative treatment, renal function (creatinine), and a patient's ability of self-judgment, and a patient's mobility and physical capability were associated with patient prognosis regarding bone and soft tissue sarcomas. Interestingly, age did not affect the patient's prognosis (> 70 vs ≦ 70). CONCLUSIONS Physical and social factors may affect the prognosis of patients with bone and soft tissue sarcomas, especially those living in non-urban areas.

A Learning Program for Treatment Recommendations by Molecular Tumor Boards and Artificial Intelligence. JAMA Oncol 2024; 10:95-102. [PMID: 38032680 PMCID: PMC10690580 DOI: 10.1001/jamaoncol.2023.5120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 08/17/2023] [Indexed: 12/01/2023]
Abstract
Importance Substantial heterogeneity exists in treatment recommendations across molecular tumor boards (MTBs), especially for biomarkers with low evidence levels; therefore, the learning program is essential. Objective To determine whether a learning program sharing treatment recommendations for biomarkers with low evidence levels contributes to the standardization of MTBs and to investigate the efficacy of an artificial intelligence (AI)-based annotation system. Design, Setting, and Participants This prospective quality improvement study used 50 simulated cases to assess concordance of treatment recommendations between a central committee and participants. Forty-seven participants applied from April 7 to May 13, 2021. Fifty simulated cases were randomly divided into prelearning and postlearning evaluation groups to assess similar concordance based on previous investigations. Participants included MTBs at hub hospitals, treating physicians at core hospitals, and AI systems. Each participant made treatment recommendations for each prelearning case from registration to June 30, 2021; participated in the learning program on July 18, 2021; and made treatment recommendations for each postlearning case from August 3 to September 30, 2021. Data were analyzed from September 2 to December 10, 2021. Exposures The learning program shared the methodology of making appropriate treatment recommendations, especially for biomarkers with low evidence levels. Main Outcomes and Measures The primary end point was the proportion of MTBs that met prespecified accreditation criteria for postlearning evaluations (approximately 90% concordance with high evidence levels and approximately 40% with low evidence levels). Key secondary end points were chronological enhancements in the concordance of treatment recommendations on postlearning evaluations from prelearning evaluations. Concordance of treatment recommendations by an AI system was an exploratory end point. Results Of the 47 participants who applied, 42 were eligible. The accreditation rate of the MTBs was 55.6% (95% CI, 35.3%-74.5%; P < .001). Concordance in MTBs increased from 58.7% (95% CI, 52.8%-64.4%) to 67.9% (95% CI, 61.0%-74.1%) (odds ratio, 1.40 [95% CI, 1.06-1.86]; P = .02). In postlearning evaluations, the concordance of treatment recommendations by the AI system was significantly higher than that of MTBs (88.0% [95% CI, 68.7%-96.1%]; P = .03). Conclusions and Relevance The findings of this quality improvement study suggest that use of a learning program improved the concordance of treatment recommendations provided by MTBs to central ones. Treatment recommendations made by an AI system showed higher concordance than that for MTBs, indicating the potential clinical utility of the AI system.

Abstract
A variety of immune-related adverse events(irAEs)occur during the use of immune checkpoint inhibitors, and delayed detection may make it difficult to continue treatment. To detect irAEs as early as possible, we have been administering an irAEs self-reported interview system(ISRIS)to all outpatients using a tablet device. We conducted a retrospective study of outpatients who received pembrolizumab, nivolumab, atezolizumab, ipilimumab, and durvalumab and utilized the ISRIS from June 2019 to May 2020. The survey items were the primary disease, initial symptoms of irAEs, and detected irAEs. The total number of patients was 140, and the total number of interviews was 1,095. Overall, 42 irAEs occurred. The ISRIS is useful for detecting subjective skin disorders. However, its detection rate of myocarditis and thyroid, hepatic, and renal dysfunction was low, and there is room for improvement. We are currently developing an ISRIS application that maintains sensitivity and increases specificity to allow for early detection of irAEs at home.

Frequency and component analysis of contaminants generated in preparation of anticancer agents using closed system drug transfer devices (CSTDs). Sci Rep 2022; 12:139. [PMID: 34996936 PMCID: PMC8741972 DOI: 10.1038/s41598-021-03780-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 11/29/2021] [Indexed: 11/30/2022] Open
Abstract
Occupational exposure of anticancer agents during their preparation has been recognized as a serious hazard. Closed system drug transfer devices (CSTDs) enable “safe” preparation of agents for medical personnel and ensure a safe hospital environment. However, artificial particles of infusion materials have been reported during CSTD use. Here, the incidence of insoluble fine particles during preparation of anticancer agents using CSTDs was examined. Visible insoluble fine particles were found in 465 (9.4%) of 4948 treatment cases at Ehime University Hospital with CSTD use. Contaminants occurred more frequently during preparation of monoclonal antibodies than cytotoxic anticancer agents (19.4% vs. 4.1%, respectively, P < 0.01). A similar survey was conducted at nine hospitals to investigate the incidence of insoluble fine particles with or without CSTDs. Insoluble fine particles were detected in 113 (15.4%) of 732 treatment cases during preparation of monoclonal antibodies with CSTD use. In contrast, the occurrence of insoluble fine particles without CSTDs was found in only 3 (0.073%) of 4113 treatment cases. Contamination with CSTDs might cause harmful effects on patients during cancer therapy. We strongly recommend the use of in-line filters combined with infusion routes after CSTD use to avoid contamination-associated adverse events.

Abstract
AIM In our aging society, the number of patients with both cancer and dementia has recently been increasing. One of the major clinical questions is whether patients with dementia could receive appropriate cancer treatment. The purpose of this study is to know the prognosis of patients with both cancer and impaired decision-making as a symptom of dementia, and to discuss the proper cancer treatment of the patients with dementia. METHODS Patients newly diagnosed with both cancer and impaired decision-making as a symptom of dementia at Ehime University Hospital between January 2010 and December 2016 were reviewed. The data of patients with cancer were retrospectively analyzed using an electronic medical record system. RESULTS In total, 9354 cases were diagnosed with cancer in the Ehime University Hospital over 7 years, and only 105 (1.1%) cases with impaired decision-making as a symptom of dementia were recorded by medical professionals, probably due to poor attention to the cognitive functions of patients with cancer. Analysis of the cancer prognosis of these patients showed that a better prognosis was seen in patients with any therapeutic interventions than in those with no treatment for the cancer itself. However, the prognosis of patients was not significantly different between standard and non-standard treatments. CONCLUSIONS This study suggests that the poor interest of medical professionals in the cognitive function of patients with cancer at the time of diagnosis of cancer and the lack of any guidelines for patients with both cancer and dementia are major problems in our aging society.

Abstract
BACKGROUND Positron Emission Tomography-Computed Tomography (PET-CT) has been changing diagnostic and therapeutic strategies for patients with cancers, and several PET-CT-related prognostic factors have been reported. We have focused on metabolic tumor volumes (MTVs) over the whole body and in specific organs using 18F-PET-CT imaging, and have compared clinical data to know the prognosis of patients with diffuse large B cell lymphoma (DLBCL). PATIENTS AND METHODS From January 2006 to December 2016, patients who were newly diagnosed for de novo DLBCL and who received 18F-FDG PET-CT scans for disease staging at Ehime University Hospital were reviewed. RESULTS A total of forty out of 108 patients with DLBCL were analyzed. The median and the average follow-up were 3.9 years and 3.6 years. Both MTV50 and MTV60 whole-body searching indicated effective prognostic values for patients with DLBCL statistically (P = 0.027). However, analysis of MTVs in the spleen and in bone marrow did not provide any prognostic value. Receiver operating characteristic (ROC) analysis indicated that the cutoff level 25.8 in MTV60 is the most effective prognostic value (P = 0.022) which predicts patient survival after treatment with R-CHOP chemotherapy. CONCLUSION MTV60 using whole-body scanning appears to be an effective indicator in DLBCL and indicates the patient prognosis.

R-CHOP-14 versus R-CHOP-14/CHASER for upfront autologous transplantation in diffuse large B-cell lymphoma: JCOG0908 study. Cancer Sci 2020; 111:3770-3779. [PMID: 32767806 PMCID: PMC7540987 DOI: 10.1111/cas.14604] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 07/26/2020] [Accepted: 07/28/2020] [Indexed: 12/22/2022] Open
Abstract
The efficiency of upfront consolidation with high‐dose chemotherapy/autologous stem‐cell transplantation (HDCT/ASCT) for newly diagnosed high‐risk diffuse large B‐cell lymphoma (DLBCL) may be influenced by induction chemotherapy. To select better induction chemotherapy regimens for HDCT/ASCT, a randomized phase II study was conducted in high‐risk DLBCL patients having an age‐adjusted International Prognostic Index (aaIPI) score of 2 or 3. As induction chemotherapy, 6 cycles of R‐CHOP‐14 (arm A) or 3 cycles of R‐CHOP‐14 followed by 3 cycles of CHASER (arm B) were planned, and patients who responded proceeded to HDCT with LEED and ASCT. The primary endpoint was 2‐y progression‐free survival (PFS), and the main secondary endpoints included overall survival, overall response rate, and adverse events (AEs). In total, 71 patients were enrolled. With a median follow‐up of 40.3 mo, 2‐y PFS in arms A and B were 68.6% (95% confidence interval [CI], 50.5%‐81.2%) and 66.7% (95% CI: 48.8%‐79.5%), respectively. Overall survival at 2 y in arms A and B was 74.3% (95% CI: 56.4%‐85.7%) and 83.3% (95% CI: 66.6%‐92.1%). Overall response rates were 82.9% in arm A and 69.4% in arm B. During induction chemotherapy, 45.7% and 75.0% of patients in arms A and B, respectively, had grade ≥ 3 non‐hematologic toxicities. One patient in arm A and 6 in arm B discontinued induction chemotherapy due to AEs. In conclusion, R‐CHOP‐14 showed higher 2‐y PFS and less toxicity compared with R‐CHOP‐14/CHASER in patients with high‐risk DLBCL, suggesting the former to be a more promising induction regimen for further investigations (UMIN‐CTR, UMIN000003823).

Abstract
Screening for total pain and sharing of patient information including adverse events for patients receiving chemotherapy by medical staff is needed in clinical practice. We introduced a sharing system for patient-oriented outcome sheets via a touch panel at an outpatient chemotherapy clinic. This study aimed to assess whether the system contributes to the improved management of treatment-related adverse events. We retrospectively analyzed data from a total of 215 patients at Ehime University Hospital using their electronic medical records from April to August 2015. Forty of these patients had received interventions relating to treatment-related adverse events. The proportion of a total number of interventions before and after the sharing system was 42/282(14.9%)and 45/215(20.9%), respectively. The proportion of a total number of interventions at the first course of outpatient chemotherapy also increased from 9/40(22.5%)to 14/40(35%)compared with before the sharing system. The purpose of interventions were for insomnia, anorexia, and cancer-related pain, etc., listed in order of degree of frequency. These results suggest that a sharing system of patient-reported interview sheets contributes to tracking treatment -related adverse events and aids in ensuring interventions can be efficiently performed by multidisciplinary team members.

Liquid Formulation of Gemcitabine Increases Venous Pain in Patients With Cancer: A Retrospective Study. Clin Ther 2020; 42:712-719. [PMID: 32160969 DOI: 10.1016/j.clinthera.2020.02.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 01/30/2020] [Accepted: 02/13/2020] [Indexed: 11/24/2022]
Abstract
PURPOSE Venous pain induced by peripheral intravenous infusion of gemcitabine has remained an unresolved issue in clinical practice. This study aimed to identify differences between gemcitabine formulations as well as risk factors associated with gemcitabine-induced venous pain in patients with cancer. METHODS We retrospectively analyzed data from consecutive patients with cancer who had received chemotherapy including a lyophilized or liquid formulation of gemcitabine diluted with 5% glucose solution via a peripheral vein. The study was conducted at Ehime University Hospital using electronic medical records dated between January 2015 and July 2017. The primary end point was the prevalence of venous pain at the administration site during gemcitabine infusion, classified as injection site reaction of grade ≥2 according to the Common Terminology Criteria for Adverse Events, version 4.0. A multivariate logistic regression analysis with generalized estimating equations for longitudinal data was used to identify risk factors for venous pain during all courses of gemcitabine treatment. FINDINGS A total of 1150 treatment courses in 141 Japanese patients were evaluated in this study. Venous pain occurred in 115 courses (10.0%) and in 49 patients (34.8%). The multivariate logistic regression analysis with generalized estimating equations revealed that a dose increase of gemcitabine and use of the liquid formulation of gemcitabine were significantly associated with an increased risk for venous pain (dose increase, adjusted odds ratio [OR] = 1.25; 95% CI, 1.11-1.40 [P < 0.001]; and liquid formulation, adjusted OR = 12.43, 95% CI, 5.61-27.51 [P < 0.001]), whereas age, course number of gemcitabine, and use of the soft-back product of 5% glucose solution were significantly associated with a reduced risk for venous pain (age, adjusted OR = 0.75; 95% CI, 0.57-0.98 [P = 0.037]; course number, adjusted OR = 0.96; 95% CI, 0.92-0.99 [P = 0.023]; and soft back, adjusted OR = 0.39; 95% CI, 0.21-0.74 [P = 0.004]). IMPLICATIONS The use of the liquid formulation of gemcitabine was associated with a significant increase in the frequency of gemcitabine-induced venous pain despite dilution with 5% glucose solution compared to that with the lyophilized formulation. The lyophilized formulation of gemcitabine should hence be used in peripheral intravenous infusion for the treatment of patients with cancer.

Abstract
BACKGROUND Differentiation between primary ocular adnexal mucosa-associated lymphoid tissue (POA-MALT) lymphoma and reactive lymphoid hyperplasias sometimes may be difficult. We have examined the treatment-associated mortality of POA-MALT lymphoma after confirmed diagnosis and evaluated their proper treatments. PATIENTS AND METHODS From 1991 through 2016, cases of POA-MALT lymphoma were retrospectively analyzed based on their pathological and molecular/immunological diagnoses. RESULTS A total of 78 cases with POA-MALT lymphoma with a median age of 66 years were analyzed over median/mean observations of 6.4/7.1 years. Forty-four patients (56%) were diagnosed with IgH gene clonality and 10 patients (13%) were diagnosed with flow cytometric analysis in addition to the pathological decision. The rest (24 patients, 31%) were diagnosed employing pathological decisions of hemato-pathologists and clinical decisions. All patients, except cases of watchful waiting, achieved complete remission. After initial treatment, 68 patients (87%) presented disease-free during the observation period. As treatment, a radiotherapy-based strategy was followed with 15 patients (19%, group A). Immuno-chemotherapy was administered to 24 patients (31%, B). Surgical extraction only was selected for 36 patients (46%, C). Watchful waiting was selected with three patients (4%). Recurrence after the initial treatment was found in one patient (7%) out of A, in three patients (13%) out of B, and in six patients (17%) out of C, respectively. Progression-free survivals at 5 and 10 years were 100 and 100% in A, 95 and 75% in B, and 88 and 81% in C, respectively. The recurrence rates between the patients who were diagnosed with only pathological decision (n = 24) and the patients who were diagnosed with molecular and immunological procedures (n = 54) did not show any statistical differences. CONCLUSION Our results indicate that radiotherapy-based treatment strategies for patients with POA-MALT lymphoma show a low rate of recurrence and may improve their prognosis even after the accurate diagnosis. However, contamination of the cases with reactive (polyclonal) lymphoid hyperplasia into those with MALT lymphoma should be carefully removed to avoid unnecessary treatment for malignancies that do not exist.

Abstract
Abstract
Background: T-cell therapy can be a promising treatment option even in patients with refractory malignancies including myeloma. NY-ESO-1 is a well-known cancer-testis antigen which is expressed by refractory myeloma cells, and a NY-ESO-1_157-165 peptide presented by an HLA-A*02:01 molecule (A2/NY-ESO-1_157) has been demonstrated. Adoptive transfer therapy using T-cells modified with T-cell receptor (TCR) specific for A2/NY-ESO-1_157 successfully induced clinical responses in patients with advanced myeloma. However, TCR-transduced T-cells are laborious to generate and possess the cross-reactivity induced by mispaired and/or introduced TCRs, resulting in increase of unwanted toxicities. T-cell therapy utilizing modified antibodies containing single chain fragment variables (scFvs), such as chimeric antigen receptor (CAR) and bispecific antibody (BiTE) would overcome the issues concerning TCR-T therapy and expand clinical versatility of T-cell therapy targeting NY-ESO-1 in the treatment of refractory myeloma. In this study, we have generated both CAR and BiTE which recognize A2/NY-ESO-1_157, and assessed their anti-myeloma reactivity and cross-reactivity in vitro and in vivo. Methods: Expression of NY-ESO-1 in a panel of myeloma cell lines was examined by real-time PCR and Western blotting. Based on the structure of previously reported monoclonal antibody specific for A2/NY-ESO-1_157 (clone: 3M4E5), we newly synthesized an A2/NY-ESO-1_157-specific scFv. Second generation CAR possessing an scFv linked with CD28 and CD3z was generated. A BiTE composed of an A2/NY-ESO-1_157-specific scFv and a CD3e-binding scFv was also generated. A2/NY-ESO-1_157-specific reactivity mediated by CAR and BiTE-redirected T-cells were assessed by A2/NY-ESO-1_157 tetramer and multiple cytokine assays. Specific lysis of targeT-cells by those T-cells was measured by standard Cr-release assay. Alanine scanning of NY-ESO-1_157 peptide was performed, and nine peptides homologous to NY-ESO-1_157 were synthesized. Cross-reactivity of CAR and BiTE-redirected T-cells for these peptides and NY-ESO-1_157 peptide presented by HLA-A2 alleles was evaluated. NOG mice engrafted with a luciferase-transduced A2+NY-ESO-1+ myeloma cell line (U266/SLR) were treated with CAR-T-cells or T-cells with BiTE, and tumor sizes were measured by bioluminescence imaging assays. Results: Three out of six myeloma cell lines we tested abundantly expressed NY-ESO-1 mRNA and protein. CAR-T-cells established from five out of five donors showed A2/NY-ESO-1_157-specific reactivity. These gene-modified T-cells recognized and killed targeT-cells which naturally process and present A2/NY-ESO-1_157, resulting in anti-myeloma reactivity to A2+NY-ESO-1+ U266 myeloma cells. Newly generated BiTE successfully engaged A2/NY-ESO-1_157 expressing targeT-cells with CD3+ T-cells, thereby peripheral T-cells produced multiple cytokines against A2+NY-ESO-1+ targeT-cells, and lysed them. CAR and BiTE-redirected T-cells can possess cross-reactivity for some of homologous peptides and NY-ESO-1_157 peptide presented by HLA-A2 alleles. Functional avidity of BiTE-redirected T-cells for A2/NY-ESO-1_157 was comparable with that of CAR-T-cells. Importantly, tumor growth was suppressed by intravenous injection of CAR-T-cells and T-cells in combination with BiTE, and their antitumor effects were similarly observed. Conclusions: T-cells redirected with CAR and BiTE both successfully showed anti-myeloma reactivity in an A2/NY-ESO-1_157-specific manner. An A2/NY-ESO-1_157-specific BiTE displayed a potential to induce sufficient antitumor T-cell responses against myeloma cells in vivo. These two scFv-based modalities also require to pay attention to unwanted cross-reactivity; however, they can provide efficacious and flexible options for the treatment of HLA-A2-positive patients with refractory myeloma.

Abstract
PURPOSE The aim of this study was to identify a high-risk or low-risk population for chemotherapy-induced nausea and vomiting among patients with breast cancer treated with a current standard 3-drug antiemetic regimen and receiving anthracycline. METHODS We analyzed data from chemotherapy-naive Japanese patients with breast cancer, who had received the first cycle of anthracycline-based regimen and were treated with a 3-drug combination of aprepitant, palonosetron, and dexamethasone. This study was carried out at Ehime University Hospital (Toon, Japan) using electronic medical records from May 2011 to June 2017. The primary end point was complete response (CR), which was defined as no emesis and no use of rescue medication. FINDINGS A total of 103 patients were included in this study. The percentages of patients who had a CR in the overall, acute, and delayed phases were 35.0%, 40.8%, and 50.5%, respectively. Multivariate logistic regression analysis revealed that age <55 years and body mass index <27.5 kg/m2 were significantly associated with an increased risk for CR failure in the overall and acute phases. In contrast, a history of alcohol habit was significantly associated with a decreased risk for CR failure in overall phase. IMPLICATIONS The present findings suggest that, among patients with breast cancer receiving anthracycline and treated with aprepitant, palonosetron, and dexamethasone, patients younger than 55 years and having a body mass index <27.5 kg/m2 are high-risk populations for chemotherapy-induced nausea and vomiting, whereas those with a history of habitual alcohol consumption is a low-risk one.

Olanzapine plus aprepitant, palonosetron, and dexamethasone for nausea and vomiting in patients with breast cancer receiving anthracycline: A retrospective study. Sci Rep 2018; 8:16232. [PMID: 30389996 PMCID: PMC6214966 DOI: 10.1038/s41598-018-34618-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Accepted: 10/17/2018] [Indexed: 02/08/2023] Open
Abstract
This study aimed to compare the antiemetic efficacy and safety of a four-drug combination with those of a standard three-drug combination in Japanese patients with breast cancer treated with anthracycline. We retrospectively analyzed data from Japanese patients with breast cancer, who had received their first cycle of anthracycline and were treated with aprepitant, palonosetron, and dexamethasone with or without olanzapine. This retrospective observational study was performed at Ehime University Hospital using the electronic medical records. Multivariable and propensity score-adjusted analyses were performed to compare the onset of complete response (CR) failure between the groups. One-hundred and thirty patients were included in this study and the four- and three-drug group had 22 and 108 patients, respectively. Similar to multivariable logistic regression analysis, propensity-adjusted logistic regression analysis revealed that the four-drug group was markedly associated with a decreased odds of CR failure in the overall, acute, and delayed phases (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.10–0.73; OR: 0.28, 95% CI: 0.10–0.76; and OR: 0.15, 95% CI: 0.04–0.57, respectively). Additionally, treatment-related adverse events were well tolerated in both the groups. These findings suggest that the antiemetic efficacy of the four-drug combination is superior to that of the standard three-drug combination.

Abstract
Although induction immunochemotherapy including high‐dose cytarabine and rituximab followed by high‐dose chemotherapy (HDC) with autologous stem cell transplantation (ASCT) is recommended for younger patients (≤65 years old) with untreated mantle cell lymphoma (MCL), no standard induction and HDC regimen has been established. We conducted a phase II study of induction immunochemotherapy of R‐High‐CHOP/CHASER followed by HDC of LEED with ASCT in younger patients with untreated advanced MCL. Eligibility criteria included untreated MCL, stage II bulky to IV, and age 20‐65 years. Patients received 1 cycle of R‐High‐CHOP followed by 3 cycles of CHASER every 3 weeks. Peripheral blood stem cells (PBSC) were harvested during CHASER. LEED with ASCT was delivered to patients who responded to R‐High‐CHOP/CHASER. Primary endpoint was 2‐year progression‐free survival (PFS). From June 2008 to June 2012, 45 patients (median age 59 years; range 38‐65 years) were enrolled. PBSC were successfully harvested from 36 of 43 patients. Thirty‐five patients completed ASCT. Two‐year PFS was 77% (80% CI 68‐84), which met the primary endpoint. Five‐year PFS and overall survival were 52% (95% CI 34‐68%) and 71% (95% CI 51‐84%), respectively. Overall response and complete response rates after induction immunochemotherapy were 96% and 82%, respectively. The most common grade 4 toxicities were hematological. In younger patients with untreated MCL, R‐High‐CHOP/CHASER/LEED with ASCT showed high efficacy and acceptable toxicity, and it can now be considered a standard treatment option.

Abstract
BACKGROUND Follicular lymphoma (FL) is the most common type of non-Hodgkin lymphoma (NHL), with indolent progression. Several treatment options are selected, based not only on disease status, quality of life (QOL), and age of patient, but also on recent increasing medical costs. We retrospectively analysed the first-line treatment of FL with regard to treatment outcomes and medical economics, and discuss the appropriate strategies for FL. METHODS Data on a total of 69 newly-diagnosed patients with FL was retrospectively collected from 2001 to 2015. RESULTS The median age of the patients was 60 years and the median follow-up was 58 months. A total of 25 cases with FL were treated with R monotherapy, and 28 cases were treated with R-CHOP as first-line treatment. The factors affecting the decision of physicians to use R or R-CHOP treatment were serum level of lactate dehydrogenase (LDH) and disease stage. The first-line treatment-associated survival did not show any statistical differences between R and R-CHOP. The average hospitalization and average of all medical costs during the first-line treatment were 4.1 days (R) versus 55.7 days (R-CHOP), and JPY 1,707,693 (USD 15,324) (R) versus JPY 2,136,117 (USD 19,170) (R-CHOP), respectively. CONCLUSION R monotherapy for patients whose diseases show low tumor burden and who are not candidates for local treatment has benefits as a first-line treatment compared to R-CHOP, based on the patients' QOL and medical economics.

Abstract
Background Venous pain induced by peripheral intravenous administration of oxaliplatin remains clinically unresolved. Objective The aim of this study was to determine the efficacy of comprehensive intervention care for venous pain in colorectal cancer patients receiving oxaliplatin. Setting A Japanese tertiary hospital. Method We treated all outpatients after April 2012 with comprehensive intervention care including pre-warming of the oxaliplatin solution, use of a hot compress, and pH adjustment by combination with dexamethasone. We retrospectively reviewed the electronic medical records from colorectal cancer patients who had received oxaliplatin via a peripheral vein between December 2009 and June 2014. Main outcome measures The primary endpoint of this study was the incidence of venous pain at the administration site during oxaliplatin infusion, according to injection site reaction grade ≥ 2. Results We evaluated 271 treatment courses in 59 patients. Venous pain occurred in 42 courses (15.5%) among 26 patients. Multivariate logistic regression analysis revealed that female gender and body mass index ≥ 25 kg/m2 were significantly associated with an increased risk of venous pain during all courses (adjusted odds ratio [OR]: 3.18, 95% confidence interval [CI] 1.35-7.92; P < 0.01; and adjusted OR: 3.37, 95% CI 1.26-9.40; P = 0.02, respectively), whereas comprehensive intervention care were significantly associated with reduced risk of venous pain during all courses (adjusted OR: 0.10, 95% CI 0.02-0.44; P < 0.01). Conclusion Comprehensive intervention care is a clinical treatment option for oxaliplatin-induced peripheral venous pain in patients with colorectal cancer, especially females with obesity.

Abstract
AIMS Pneumocystis Jirovecii (PJ) is regarded as an agent of fungal infection and in cases of pneumocystis pneumonia (PCP) in immune-compromised patients including cancer patients. It is not clear what kinds of cancer, treatments, and environment need prophylaxis for PCP. In this study, we have analyzed the detectability of PJ DNA from sputum, and discussed prophylaxis and risk factors regarding PCP. METHODS A total of forty-nine materials (twenty-four from outpatients during cancer chemotherapies and twenty-five from healthy control subjects) was collected. Their PJ DNAs were amplified using nested PCR with specific primers of the PJ gene (the mitochondrial small subunit rRNA gene). RESULTS PJ DNA was detectable in 46% of specimens (sputum) from cancer patients during chemotherapies, and incidences of not significantly different among types of cancer and chemotherapy regimens. Prophylactic use of Sulfamethoxazole/Trimetoprim (ST) reduced the detection of PJ DNA. Detection of PJ DNA is not high among healthy non-smokers (20%) and high among healthy smokers (47%). CONCLUSIONS Prophylactic use of ST may be necessary for cancer patients during chemotherapies. Also, smoking may be associated with PJ colonization in the airway and air vesicles, and may increase the mortality rate for PCP. All patients undergoing cancer chemotherapies should cease smoking.

Abstract
Purpose The therapeutic benefit of a three-drug combination of antiemetics has not been established in moderately emetogenic chemotherapy (MEC). The aim of this study was to compare the antiemetic effectiveness and cost-saving of palonosetron plus dexamethasone (control group) with aprepitant, granisetron, and dexamethasone (study group) in cancer patients who received MEC. Methods We switched the standard antiemetic treatment from the control group to the study group in gastrointestinal cancer patients who received MEC after October 2015. The antiemetics in both groups were modified using salvage antiemetic therapy at the clinicians' discretion, according to the severity of chemotherapy-induced nausea and vomiting. We retrospectively reviewed the electronic medical records from patients, before and after switching groups, from between April 2014 and March 2016. Results We evaluated 443 treatment courses in 83 patients. The proportion of courses that included salvage antiemetic therapy in the control group and the study group was 34.8 % (116/333) and 8.2 % (9/110), respectively, and was statistically significant (p < 0.001). The mean integrated costs of antiemetics per course in the control group and the study group were 193 ± 55 USD and 143 ± 38 USD, respectively. Multivariate logistic regression analysis revealed that the study group was significantly associated with a reduced risk of requiring salvage antiemetic therapy (p = 0.038). Conclusions These results suggest that the antiemetic effectiveness and cost-saving of a three-drug combination of aprepitant, generic granisetron, and dexamethasone was superior to a two-drug combination of palonosetron plus dexamethasone in gastrointestinal cancer patients who received MEC.

Non-steroidal anti-inflammatory drugs induce severe hematologic toxicities in lung cancer patients receiving pemetrexed plus carboplatin: A retrospective cohort study. PLoS One 2017; 12:e0171066.

Abstract
Purpose As the major toxicity induced by pemetrexed plus carboplatin is severe hematologic toxicities, the aim of this study was to determine the risk factors for severe hematologic toxicities in lung cancer patients. Methods We retrospectively investigated data from lung cancer patients who had received pemetrexed plus carboplatin, with or without bevacizumab. This observational study was carried out at Ehime University Hospital using electronic medical records dating from July 2009 to March 2015. Severe hematologic toxicities were defined as grade 3 or 4, according to the Common Terminology Criteria for Adverse Events, version 4.0. Results Forty-two patients were included in the study. The incidence of grade 3 or 4 hematologic toxicities during the first cycle of chemotherapy and during all cycles was 19.0% and 16.1%, respectively. Multivariate time-depend generalized estimating equations logistic regression analysis revealed that regular use of non-steroidal anti-inflammatory drugs (NSAIDs) was significantly associated with an increased risk of severe hematologic toxicities during all cycles (adjusted odds ratio (OR): 8.32, 95% confidence interval (CI): 1.27–54.38; p = 0.03), whereas creatinine clearance of <45 mL/min was not significantly associated with an increased risk of severe hematologic toxicities during all cycles (adjusted OR: 0.91, 95% CI: 0.25–3.34; p = 0.88). Conclusions The results suggest that severe hematologic toxicities in patients receiving carboplatin-based pemetrexed may be significantly induced by the inhibition of renal tubular pemetrexed secretion through drug–drug interactions between NSAIDs and pemetrexed rather than through glomerular filtration of pemetrexed, even with moderate to sufficient renal function.

Abstract
Vancomycin-induced thrombocytopenia is a rare adverse reaction that may be overlooked because no specific diagnostic test is currently available. We herein report a patient with vancomycin-induced immune thrombocytopenia who was diagnosed by the detection of vancomycin-dependent anti-platelet antibody with flow cytometry. An IgG antibody in the patient's serum reacted with platelets only in the presence of vancomycin. Severe thrombocytopenia gave rise to life-threatening gastrointestinal bleeding, which was quickly resolved after effective platelet transfusion following the cessation of vancomycin administration. This report suggests that the flow cytometric test is useful for the differential diagnosis of thrombocytopenia and platelet transfusion should be performed after the cessation of vancomycin administration.

Abstract
Venous pain induced by oxaliplatin(L-OHP)is a clinical issue related to adherence to the Cape OX regimen. To prevent LOHP- induced venous pain, we provided nursing care to outpatients who were administered a preheated L -OHP diluted solution using a hot compress. We retrospectively evaluated the risk factors for colorectal cancer patients who had L -OHP induced phlebitis and venous pain. Furthermore, the preventive effect of nursing care was compared between inpatients and outpatients from January 2010 to March 2012. At the L-OHP administration site, any symptoms were defined as phlebitis, whereas pain was defined as venous pain. A total of 132 treatment courses among 31 patients were evaluated. Multivariate logistic regression analysis revealed that both phlebitis and venous pain were significantly more common in female patients (adjusted odds ratio, 2.357; 95%CI: 1.053-5.418; and adjusted odds ratio, 5.754; 95%CI: 2.119-18.567, respectively). The prevalence of phlebitis and venous pain did not differ between inpatients and outpatients (phlebitis, 61.3% vs 67.7%; venous pain, 29.0%vs 19.4%). These results suggest that administration of L-OHP via a central venous route should be considered in female patients.

Abstract
Background IgG4-related disease (IgG4-RD) is a new clinical entity of unknown etiology characterized by elevated serum IgG4 and tissue infiltration by IgG4-positive plasma cells. Although aberrancies in acquired immune system functions, including increases in Th2 and Treg cytokines observed in patients with IgG4-RD, its true etiology remains unclear. To investigate the pathogenesis of IgG4-RD, this study compared the expression of genes related to innate immunity in patients with IgG4-RD and healthy controls. Materials and Methods Peripheral blood mononuclear cells (PBMCs) were obtained from patients with IgG4-RD before and after steroid therapy and from healthy controls. Total RNA was extracted and DNA microarray analysis was performed in two IgG4-RD patients to screen for genes showing changes in expression. Candidate genes were validated by real-time RT-PCR in 27 patients with IgG4-RD and 13 healthy controls. Results DNA microarray analysis identified 21 genes that showed a greater than 3-fold difference in expression between IgG4-RD patients and healthy controls and 30 genes that showed a greater than 3-fold change in IgG4-RD patients following steroid therapy. Candidate genes related to innate immunity, including those encoding Charcot–Leyden crystal protein (CLC), membrane-spanning 4-domain subfamily A member 3 (MS4A3), defensin alpha (DEFA) 3 and 4, and interleukin-8 receptors (IL8R), were validated by real-time RT-PCR. Expression of all genes was significantly lower in IgG4-RD patients than in healthy controls. Steroid therapy significantly increased the expression of DEFA3, DEFA4 and MS4A3, but had no effect on the expression of CLC, IL8RA and IL8RB. Conclusions The expression of genes related to allergy or innate immunity, including CLC, MS4A3, DEFA3, DEFA4, IL8RA and IL8RB, was lower in PBMCs from patients with IgG4-RD than from healthy controls. Although there is the limitation in the number of patients applied in DNA microarray, impaired expression of genes related to innate immunity may be involved in the pathogenesis of IgG4-RD as well as in abnormalities of acquired immunity.

Abstract
The "Cancer Chemotherapy and its Management" subcommittee at the Ehime Cancer Care Network Priority Hospitals (Ehime Cancer Kyoten Hospitals)with a focus on medical expenses associated with chemotherapy, surveyed awareness among 98 clinicians regarding certifications of eligibility for Limited Health Insurance Payments during cancer treatment. This committee also lists social and clinical problems encountered at the Ehime Cancer Care Network Priority Hospitals. In our survey, 78% of clinicians were consulted about medical expenses associated with chemotherapy and were actively involved in resolving medical expense problems and resulting correspondences. However, only 38% of clinicians could explain the details of the Japanese guideline on the catastrophic cap and the certifications of eligibility for Limited Health Insurance Payments. This knowledge deficit was more pronounced in younger residents. From our analyses of the awareness about medical expenses among clinicians, we recommend the establishment of the following systems for the management of cancer patients. First, establish a reporting system and early consultation on the catastrophic cap and the certifications of eligibility before initiating cancer treatment. Second, education regarding medical expenses should be mandatory for clinicians, especially for young residents. Third, patients with cancer suffering in the interval of the medical expense and the social system should be relieved with new systems.

Abstract
Venous pain induced by oxaliplatin (L-OHP) is a clinical problem in relation to adherence in the CapeOX regimen. We investigated the preventive effect of nursing care preheating administration of L-OHP a hot compress for colorectal cancer patients who received L-OHP via the peripheral venous route between January 2010 and January 2011. L-OHP was diluted in 500 mL of 5% glucose and administered by 2 hours. We evaluated a total of 64 courses among fifteen patients. The presence of any symptoms, any pain with or without touch, and some symptoms of numbness at the L-OHP-administered arm were defined as phlebitis, venous pain, and acute peripheral neuropathy, respectively. The prevalence of phlebitis, venous pain, and acute peripheral neuropathy in the nursing care group was 56.5%, 32.6%, and 25.8%, respectively, which was not significantly less in comparison with the control group (72.2%, 38.9%, and 54.5%, respectively). These results suggest that both types of nursing care, preheating administration and a hot compress, may be effective for the relief of acute peripheral neuropathy induced by L-OHP.

Analysis of chemotherapy-induced neutropenia and optimal timing for prophylactic use of G-CSF in B-cell non-Hodgkin lymphoma patients treated with R-CHOP. Int J Clin Oncol 2013; 19:178-85. [PMID: 23380958 DOI: 10.1007/s10147-013-0523-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2012] [Accepted: 01/14/2013] [Indexed: 11/24/2022]
Abstract
BACKGROUND Febrile neutropenia (FN) is one of the serious complications of chemotherapy. However, the hematological nadir after chemotherapy and the timing of prophylaxis for FN remain unclear, especially for outpatients. METHODS We prospectively analyzed laboratory data from outpatients treated with a single chemotherapy regimen, rituximab (R)-CHOP, on three consultation days (days 8, 10, and 15) after chemotherapy to identify any factors that might predict the onset of the hematological nadir and the optimal timing of G-CSF prophylaxis. RESULTS A total of 100 courses of chemotherapy (total 33 patients) were analyzed. Onset of the hematological nadir was not predictable in any of the patients who had a white blood cell count (WBC) of >5,500 × 10(6)/L and/or monocyte count of >80 × 10(6)/L on day 8, and thus there was little opportunity for G-CSF prophylaxis in each treatment course. Among patients who had a WBC count of 1,500-5,500 × 10(6)/L on day 8, the monocyte count on day 8 was significantly associated with the hematological nadir. Patients who had a monocyte count of <5 × 10(6)/L on day 8, were identified as a high-risk group for neutropenia for whom G-CSF administration during the current treatment course should be considered. CONCLUSION Our results indicate that, in outpatients receiving R-CHOP chemotherapy, the monocyte count on day 8 is a useful marker of the hematological nadir, allowing an opportunity for G-CSF prophylaxis.

Concurrent administration of rituximab and CHOP chemotherapeutic agents for outpatients with CD20-positive lymphoma. Anticancer Agents Med Chem 2012; 12:829-34. [PMID: 22721383 DOI: 10.2174/187152012802650138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2012] [Revised: 06/11/2012] [Accepted: 06/13/2012] [Indexed: 11/22/2022]
Abstract
R (rituximab)-CHOP (cyclophosphamide, adriamycin, vincristin, and prednisone) is given to outpatients with CD20-positive lymphoma as a standard treatment. However, this regimen requires long-term infusion because of the necessity for monitoring the infusion reaction (IR) during R administration. In this study, pharmacological changes in anti-tumor agents were examined after the joint use of R and CHOP, and the possibility of concurrent administration of R and CHOP for outpatients was discussed. After combining antitumor agents with R, the binding capacity of R to the CD20 peptide and molecular changes in anti-tumor agents were measured by ELISA and LC/MS/MS-based analysis. At the same time, a pilot study involving concurrent administration of R and CHOP to patients with diffuse large B-cell lymphoma (DLBCL) was carried out after the first course of R-CHOP. After combining with either adriamycin or cyclophosphamide, the binding capacity of R to the CD20 antigen was equivalent to controls, and no molecular changes in adriamycin and cyclophosphamide were detected after combination with R. Twenty-one cases of DLBCL were treated safely with concurrent administration of R and CHOP. Twenty patients achieved complete remission after a full course of R-CHOP. The results indicated that long-term medication might not be necessary for outpatients treated with R-CHOP.

Abstract
Activation-induced cytidine deaminase (AID/AICDA) is required for somatic hypermutation and class-switch recombination of the immunoglobulin gene, and for c-myc translocation of germinal center-derived B-cell lymphoma. In the present study, we attempted to clarify the significance of AID associated with c-myc in the progression of follicular lymphoma (FL) using RT-PCR and quantitative real-time PCR. Tissues from the patients with grade 3 FL expressed relatively higher levels of c-myc and AID. The samples taken from a patient with FL who died within 2 years after the start of treatment showed either no or low expression of AID, despite expressing high levels of c-myc. In order to examine the role of AID expression in rapidly progressive FL, the full-length AID transcript was transfected into AID-negative cell lines established from different patients with rapidly progressive FL. This led to the establishment of AID-expressing transfectants with a low proliferation rate and a significantly increased incidence of G(0)/G(1) arrest compared with controls. Our results indicate that AID may act as a negative regulator of cell survival in FL when sufficient c-myc is expressed. Switch-off or low expression of AID after c-myc amplification may correlate with the clinical outcomes of FL.

Abstract
Ehime Priority Hospitals of Cancer Care Network(Ehime Cancer Kyoten Hospitals)regularly have meetings to discus the current problems in cancer care in Ehime Prefecture. We established three subcommittees:"Registration of Cancer Incident," "Critical Paths for the Management of Patients with Cancer,"and"Palliative Care for Patients with Advanced Cancer"to exchange our opinions. We recently set up a new subcommittee related to the physical and spiritual care of patients undergoing chemotherapy treatment,"A Subcommittee dealing with Cancer Chemotherapy and its Management"."This subcommittee has tried to identify current problems with chemotherapy for outpatients in each institution through questionnaire and analysis. As a result of this survey, it was found that Ehime Priority Hospitals have total of seventy-three beds for outpatients undergoing chemotherapy, and that they performed chemotherapy 19, 671 times in 2008. A total of eight oncology physicians and sixteen oncology nurses were engaged in performing chemotherapy in this system. The questions patients most frequently asked during chemotherapy concerned the management of therapy-related complications, dealing with problems at night and during holidays after chemotherapy, and financial problems related to the costs of treatment. In this study we found three issues that need to be managed in Ehime Priority Hospitals. First, for the nursing of outpatients undergoing chemotherapy, more staff engaged in different types of care is required. Second, a new system to deal with emergencies at night and during holidays after chemotherapy is necessary, because Ehime Priority Hospitals use the same system to deal with chemotherapy patients as for other patients. Third, cooperation between pharmacies and out-clinics is important for patient compliance during chemotherapy, especially for the administration of oral anti-tumor agents. Ehime Priority Hospitals of Cancer Care Network is trying to improve each institution while dealing with these problems.

Abstract
BACKGROUND In order to analyze the clinical activity and cost-effectiveness of granulocyte colony-stimulating factors (G-CSF), the prophylactic usage of G-CSF in patients treated with a single chemotherapy regimen during early courses was prospectively evaluated. METHODS Thirty patients with newly diagnosed non-Hodgkin lymphoma (NHL) treated with the first course of an R-CHOP regimen were enrolled randomly. After treatment with the first course of chemotherapy, a daily dose of G-CSF (lenograstim, 100 μg) was administered to half (15 cases) of the patients, and a dose of G-CSF (100 μg) was administered every other day to the other half of the patients when leukocytopenia (<1.5 × 10(9)/L) and/or neutropenia (<0.5 × 10(9)/L) occurred. Changes in leukocyte and neutrophil counts, prophylaxis, febrile neutropenia (FN) events, and cost performance between the two groups were analyzed. RESULTS No significant difference between the two groups was observed in recoveries of leukocyte and neutrophil counts and evidence of FN. The only difference was the total cost of G-CSF. CONCLUSION We concluded that every-other-day use of G-CSF was as clinically effective for the prophylaxis of FN as the daily use of G-CSF, and economically speaking, the administration of G-CSF every other day should be more beneficial for patients with NHL during early courses of R-CHOP chemotherapy.

Abstract
Only a few reports have described regression of rectal mucosa-associated lymphoid tissue (MALT) lymphoma after antibiotic treatment are generally found to be successful for gastric tumors. We examined eight rectal MALT lymphomas treated with antibiotic treatments to determine whether they regressed after treatment. We also discuss the relationship between rectal MALT lymphomas and MALT1 gene genetic abnormalities. Eight patients who had undergone antibiotic treatments were followed up with colonoscopy after initiation of the treatment. In five of the eight cases (63%) endoscopic examination showed that the rectal tumor had disappeared, which was confirmed histologically. Polymerase chain reaction for immunoglobulin heavy chain identified a monoclonal band in seven of eight cases (88%). Of the eight cases analyzed with fluorescence in situ hybridization (FISH) for MALT1 translocation, two demonstrated MALT1 gene genetic abnormality. These cases tended to be resistant to antibiotic treatment. Investigation and analysis of a large number of rectal MALT lymphomas are needed to establish suitable standards for antibiotic treatment.

Abstract
BACKGROUND Lymphoid neoplasm with 18q21.3/BCL2 and 8q24/MYC translocation to immunoglobulin (IG) genes as dual-hit lymphoma/leukemia is very rare and known to have a poor clinical outcome. DESIGN AND METHODS To clarify the clinicopathological characteristics of this malignancy, we analyzed 27 cases of cytogenetically proven dual-hit lymphoma/leukemia. RESULTS Dual-hit lymphoma/leukemia was diagnosed at presentation in 22 cases and at relapse or disease progression in 5 cases. At the time of diagnosis of dual-hit lymphoma/leukemia, extranodal involvement was found in 25 cases (93%) and central nervous system involvement occurred in 15 cases (56%). The median survival and 1-year survival rate of the 27 cases were only 6 months and 22%, respectively, after diagnosis of the dual-hit lymphoma/leukemia. Seven cases of triple-hit lymphoma/leukemia (dual-hit lymphoma/leukemia with 3q27/BCL6 translocation) were included; the median survival of these patients was only 4 months from the diagnosis of the dual-hit lymphoma/leukemia. The duration of survival of the patients with a triple-hit malignancy was shorter than that of the other 20 cases of dual-hit lymphoma/leukemia (p=0.02). The translocation partner of MYC subdivided the dual-hit cases into two groups; 14 cases of IGH and 13 cases of IGK/L. The MIB-1 index was investigated in 14 cases with aggressive B-cell lymphoma, and was higher in the group with MYC-IGH translocation (n=7) than in the MYC-IGK/L group (n=7) (p=0.02). Overall survival was not different between the MYC-IGH translocation group (n=14) and the MYC-IGK or MYC-IGL translocation group (n=13). CONCLUSIONS Dual-hit lymphoma/leukemia is a rare but distinct mature B-cell neoplasm with an extremely poor prognosis characterized by frequent extranodal involvement and central nervous system progression with either of the translocation partners of MYC.

Abstract
An 82-year-old man was referred to our hospital because of bilateral leg swelling and ecchymosis. A hemostatic study showed prolonged aPTT, <1% factor VIII coagulant activity, and a high titer (30.4 Bethesda Units/ml) of factor VIII inhibitor. The diagnosis of acquired hemophilia A (AHA) was made, and treatment with prednisolone (PSL) was started. Within one month of treatment, the hemorrhagic symptom disappeared, aPTT levels returned to normal, and his factor VIII inhibitor was eradicated; however, factor VIII inhibitor was detected again when PSL was decreased to 10 mg/day. We then added cyclosporine A (CyA) to PSL as a second line salvage therapy. CyA therapy resulted in the resolution of AHA with marked and prolonged efficacy; however, hot, red tumors appeared in his right arm and left thigh. Needle aspiration of the tumors revealed muscle abscess, and Nocardia brasiliensis was isolated. We started treatment with sulfamethoxazole-trimethoprim, and the abscess healed promptly without recurrence.

Clinical significance of co-expression of CD21 and LFA-1 in B-cell lymphoma. Int J Hematol 2009; 89:497-507.

Abstract
We previously reported that the prognosis of CD21-positive diffuse large B-cell lymphoma (DLBCL) is significantly favorable to that of CD21-negative DLBCL (Otsuka et al. in Br J Haematol 127:416-424, 2004). In this study, we attempted to clarify the biological significance of CD21 expression in B-cell lymphoma (BCL) by performing in vitro experiments using CD21 transfection into a CD21-negative lymphoma cell line and analyzing clinical data from lymphoma samples. Established clones of CD21 transfectants showed homotypic aggregation in suspension culture. Analysis of integrin expression revealed that LFA-1 appeared to be expressed on CD21 transfectants, and the cell aggregation was abrogated by anti-LFA-1 antibody. The CD21 transfectants could adhere to plastic plates coated with ICAM-1. Moreover, flow cytometry and/or immunohistochemical analyses of clinical BCL samples (n = 29) revealed positive for CD21 in all cases; LFA-1 was also expressed without exception. All BCL cells isolated from cavity fluids (n = 10) failed to express both CD21 and LFA-1. These data suggest that CD21 is tightly related to LFA-1 expression in BCL and the absence of CD21/LFA-1 expression is associated with pleural/peritoneal fluid involvement by BCL, a potential indicator of disease progression of BCL.
