    Abstract We report a case of splenic marginal zone B-cell lymphoma discovered in a 73-year-old man with cold agglutinin disease. PET/CT revealed splenomegaly with focally intense uptake of F-FDG and diffusely increased bone marrow uptake, which was considered to be secondary to hemolytic anemia. Splenectomy was performed. The histopathology of the spleen showed splenic marginal zone B-cell lymphoma with partial splenic infarction, which correlated with the area of focal intense FDG uptake. Depending on the time since onset, splenic infarctions can present as focal FDG accumulation.

    Abstract A 83-year-old female patient was admitted to our hospital due to hematological manifestation of juvenile granulocytes and macrocytic anemia. Bone marrow (BM) examination revealed erythroid dysplasia and cytoplasmic blasts, and hence the patient was diagnosed with myelodysplastic syndrome with ring sideroblasts and with single lineage dysplasia (MDS-RS-SLD). Erythrocyte transfusion was performed as a supportive therapy, and there was a gradual increase in the number of blood cells. Therefore, BM re-examination was performed and it was confirmed that the number of megakaryocytes increased, so the patient's condition was determined as myelodysplastic/myeloproliferative neoplasms with ring sideroblasts and thrombocytosis (MDS/MPN with RS-T). Incidentally, gene mutation analysis showed CALR gene mutation. Thereafter, administration of hydroxycarbamide and anagrelide did not show adverse events and complications, and a good blood count control was obtained. Furthermore, it was also confirmed that an SF3B1 gene mutation is highly positive in MDS-RS. There was no report on CALR-mutant MDS/MPN in Japan, and it is a rare disease overseas.

    Abstract A standard radiation therapy protocol for primary central nervous system marginal zone lymphoma (CNS-MZL) has not been established. The International Lymphoma Radiation Oncology Group suggested a radiation therapy dose of 30-36 Gy for lesions of well-defined CNS-MZL. We report a case of relatively low-dose whole brain radiation therapy (WBRT) for ill-defined CNS-MZL. A 56-year-old man who presented with sudden left-sided convulsions and impaired consciousness was diagnosed with CNS-MZL. The tumor had an ill-defined lesion, without cerebrospinal fluid involvement. WBRT, consisting of 25.2 Gy in 14 fractions, was administered owing to the difficulty in target delineation for focal radiation therapy. No chemotherapy was administered during the treatment course. After the 36-month follow-up period, the patient maintained complete remission without neurological disorders. This report describes the usefulness of relatively low-dose WBRT for ill-defined CNS-MZL.

    Abstract A 33-year-old male with hereditary deficiency of antithrombin III (AT III) was diagnosed with annuloaortic ectasia and scheduled for the aortic root replacement. As perioperative anticoagulation, AT III was administered to have its activity≥70% in addition to heparin. During the operation with cardiopulmonary bypass, 3,000 IU of AT III concentrate was infused, and there was no hemorrhagic complication. After the operation low-molecular-weight heparin was used instead of unfractionated heparin to avoid bleeding. However, renal infarction occurred on postoperative day 11. Heparin was continuously given in combination with 1,500 IU/day of AT III concentrate until oral warfarin reached within therapeutic range. The patient recovered without further sequelae. Cardiac surgery might be safely performed in patients with AT III deficiency by replenishing AT III concentrate to keep its activity higher than 80%.

    Abstract To elucidate the long-term outcomes of non-anthracycline-containing therapies and central nervous system (CNS) events in patients with extranodal NK/T-cell lymphoma, nasal type (ENKTL), the clinical data of 313 patients with ENKTL diagnosed between 2000 and 2013 in a nationwide retrospective study in Japan were updated and analyzed. At a median follow-up of 8.4 years, the 5-year overall survival (OS) and progression-free survival (PFS) were 71% and 64%, respectively, in 140 localized ENKTL patients who received radiotherapy-dexamethasone, etoposide, ifosfamide, and carboplatin (RT-DeVIC) in clinical practice. Nine (6.4%) patients experienced second malignancies. In 155 localized ENKTL patients treated with RT-DeVIC, 10 (6.5%) experienced CNS relapse (median, 12.8 months after diagnosis). In five of them, the events were confined to the CNS. Nine of the 10 patients who experienced CNS relapse died within 1 year after CNS relapse. Multivariate analysis identified gingival (hazard ratio [HR], 54.35; 95% confidence interval [CI], 8.60-343.35) and paranasal involvement (HR, 7.42; 95% CI, 1.78-30.89) as independent risk factors for CNS relapse. In 80 advanced ENKTL patients, 18 received steroid (dexamethasone), methotrexate, ifosfamide, L-asparaginase, and etoposide (SMILE) chemotherapy as first-line treatment. Patients who received SMILE as their first-line treatment tended to have better OS than those who did not (p = 0.071). Six (7.5%) advanced ENKTL patients experienced isolated CNS relapse (median, 2.6 months after diagnosis) and died within 4 months of relapse. No second malignancies were documented in advanced ENKTL patients. In the entire cohort, the median OS after first relapse or progression was 4.6 months. 12 patients who survived 5 years after PFS events were disease-free at the last follow-up. Of those, 11 (92%) underwent hematopoietic stem cell transplantation. Our 8-year follow-up revealed the long-term efficacy and safety of RT-DeVIC and SMILE. The risk of CNS relapse is an important consideration in advanced ENKTL.

    Abstract We conducted a randomised phase II study to determine the optimal dose and schedule of melphalan, prednisone, and bortezomib (MPB) (jRCTs031180097). Transplant-ineligible untreated multiple myeloma patients were randomised to Arm A (twice weekly bortezomib in one six-week cycle followed by eight five-week cycles of four times once weekly bortezomib with melphalan and prednisolone on days 1-4) or Arm B (nine four-week cycles of three times once weekly bortezomib with melphalan and prednisolone on days 1-4). The primary end-point was complete response (CR) rate. Of 91 patients randomised to two arms, 88 were eligible. The median cumulative bortezomib doses were 45·8 and 35·1 mg/m

    Abstract We report a case of fungemia caused by Scedosporium prolificans, an emerging pathogen. An 83-year-old man with myelodysplastic syndrome (MDS) and agranulocytosis was admitted for pneumonia in January 2009. He was treated with meropenem, minocycline, and gamma-globulin for pneumonia and G-CSF and platelet transfusion for MDS. Although he recovered from pneumonia as neutrophil count increased, intermittent fever continued. On hospital day 17, blood culture yielded fungal colonies indicating S. prolificans. Voriconazole was started immediately, but the man's general condition deteriorated with cerebral infarction and he died of cerebral hemorrhage on hospital day 65. Attention must therefore be paid to the increasing scedosporiosis incidence in Japan.

    Abstract Rituximab plus cyclophosphamide-doxorubicin-vincristine-prednisone (R-CHOP) is the standard of care for untreated diffuse large B-cell lymphoma (DLBCL). However, the schedule for rituximab administration has not been optimized. To compare standard R-CHOP with CHOP plus dose-dense weekly rituximab (RW-CHOP) in patients with untreated DLBCL, we conducted a phase 2/3 study (JCOG0601, jRCTs031180139). Patients were randomly assigned to R-CHOP (CHOP-21 with 8 doses of rituximab once every 3 weeks [375 mg/m2]) or RW-CHOP (CHOP-21 with 8 doses of weekly rituximab [375 mg/m2]) groups. The primary end point of the phase 2 component was percent complete response (%CR) of the RW-CHOP arm, whereas that of the phase 3 component was progression-free survival (PFS). Between December 2007 and December 2014, 421 untreated patients were randomly assigned to R-CHOP (213 patients) or RW-CHOP (208 patients). The %CR in the RW-CHOP arm was 85.3% and therefore met the prespecified decision criteria for the phase 2 component. With a median follow-up of 63.4 months, the 3-year PFS and overall survival were 79.2% and 88.7% in the R-CHOP arm and 80.3% and 90.4% in the RW-CHOP arm, respectively. There was no significant difference in PFS (hazard ratio, 0.95; 90.6% confidence interval, 0.68-1.31). Although the safety profile and efficacy of RW-CHOP was comparable with R-CHOP and its tolerability was acceptable, weekly rituximab in combination with CHOP during the early treatment period did not improve PFS in untreated patients with DLBCL. This trial was registered at jrct.niph.go.jp as #jRCTs031180139.
