    Abstract Diffuse large B-cell lymphoma (DLBCL) is the most common type of malignant lymphoma affecting about 14,000 patients per year in Japan. Recent progress in molecular genetic investigation has clarified the underlying mechanism of this heterogeneous disease applied to therapeutic developments. R-CHOP therapy was established as a standard regimen for DLBCL and provides a cure in many patients. However, about 30-40% of patients still develop relapsed/refractory (R/R) disease. The development of effective treatments for R/R DLBCL patients is thus an urgent issue. The development of immunotherapy for intractable DLBCL patients such as anti-CD19 chimeric antigen receptor (CAR)-T therapy and bispecific T-cell engager (BiTE) has recently progressed. This new modality demonstrates efficacy in patients with resistance to conventional anticancer drugs. The advent of emerging immunotherapy is a paradigm shift in lymphoma treatment and is important for clinicians to catch up with these changes.

    Abstract Intravascular large B-cell lymphoma is a rare disease entity of extranodal large B-cell lymphoma and is characterized by selective growth of tumor cells in the lumina of small vessels in systemic organs. The challenge in obtaining sufficient tumor cells from biopsy specimens has hampered the elucidation of underlying biology. Recent advances in xenograft models and plasma cell-free DNA have revealed that the intravascular large B-cell lymphoma has genetic features similar to those of activated B-cell-like diffuse large B-cell lymphoma and frequent genetic alterations in immune-check point related genes. In terms of clinical aspects, considering the improvement in the clinical outcomes and higher risk of secondary central nervous system (CNS) involvement in the rituximab era, phase 2 trial of R-CHOP therapy combined with high-dose methotrexate and intrathecal chemotherapy as CNS-oriented therapy was conducted. The trial, named the PRIMEUR-IVL study, displayed good progression-free survival and low cumulative incidence of secondary CNS involvement. Further research is necessary to enable a deeper understanding of the pathophysiology of the disease and further improve the clinical outcomes.

    Abstract Diffuse large B-cell lymphoma (DLBCL) represents the most common subtype of non-Hodgkin lymphoma, accounting for 30%-40% of all types of malignant lymphoma. Importantly, two distinct molecular subtypes, germinal center B-cell (GCB) type and activated B-cell (ABC) type, arising from B lymphocyte differentiation based on the gene expression profiling opened doors to uncover molecular pathogenesis in DLBCL. Since 2010, next-generation sequencing analyses have been revealing the landscape of genetic mutations in DLBCL. Reportedly, GCB DLBCL is characterized by the accumulation of genetic abnormalities of epigenetic modifiers. Conversely, the hallmark of ABC DLBCL is the constitutive activation of the NKκB signaling pathway due to mutations in related genes. From recent prospective trials, conventional R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) regimen, which is the current standard regimen for DLBCL, has been acknowledged as a well-established regimen for DLBCL. Currently, the development of a plethora of drugs targeting the activated signaling pathway and immune microenvironments is ongoing. To overcome this intractable disease with the present treatment, the breakthroughs based on molecular pathogenesis are required.

    Abstract Intravascular large B-cell lymphoma is a rare disease of the large B cells characterized by selective growth in the lumina of small vessels in systemic organs. Since first reported in 1959, the difficulty of obtaining sufficient tumor cells from biopsy specimens has hampered the elucidation of its underlying biology. Recent progress using xenograft models and plasma cell-free DNA has uncovered genetic features that are similar to those of activated B-cell type diffuse large B-cell lymphoma, including MYD88 and CD79B mutations and frequent alterations in immune check point-related genes such as PD-L1 and PD-L2. Given the improvement in clinical outcomes and a higher risk of secondary central nervous system (CNS) involvement in the rituximab era, a phase 2 trial of R-CHOP combined with high-dose methotrexate and intrathecal chemotherapy as a CNS-oriented therapy has been conducted. This trial, the PRIMEUR-IVL study, has displayed good progression-free survival and a low cumulative incidence of secondary CNS involvement. Long-term follow-up within this trial is still ongoing. Further understanding of the pathophysiology of the disease and improvements in clinical outcomes are still needed.

    Abstract The preventive effects of antihypertensive drugs on cardiovascular disease are determined by the degree to which blood pressure decreases rather than its class. Appropriate antihypertensive drugs should be selected considering compelling indications, contraindications and conditions that require the careful use of drugs and the presence or absence of complications. In hypertensive patients without compelling indications, the antihypertensive drug to be first administered should be selected from Ca channel blockers, angiotensin-receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors and diuretics. The use of two or three drugs in combination is often necessary to achieve the target of blood pressure control. Combination therapy with different classes of antihypertensive drugs exhibits potent hypotensive effects, and is useful for achieving the target of blood pressure control.

    Abstract Intravascular large B-cell lymphoma (IVLBCL) is a rare distinct disease entity of the extranodal large B-cell lymphoma type, characterized by the selective growth of tumor cells in the lumina of small vessels of various organs. Lack of remarkable lymphadenopathy and non-specific clinical abnormalities including fever of unknown origin and lactate dehydrogenase elevation generally make timely and accurate diagnosis difficult. Recent diagnostic advances in the detection of this disease using FDG-PET/CT and random skin biopsies are expected to increase the diagnostic yield. Regarding the therapeutic aspects of this disease, improvement of clinical outcomes by the application of anti-CD20 monoclonal antibody, rituximab, and a high risk of CNS recurrence have been indicated. Thus, a prospective phase II trial of immunochemotherapy combined with CNS prophylaxis is now ongoing. Previously, the difficulty of obtaining sufficient tumor samples hampered biological investigations but the novel technique developing xenograft models is opening the door to uncovering the underlying mechanisms by focusing on the fundamental biological question: "Why do tumor cells become lodged in the lumina of vessels?" This review describes the current understanding of research on IVLBCL and discusses the future prospects for this disease entity.

    Abstract The guidelines for the use of ambulatory blood pressure monitoring published from Japanese Circulation Society in 2010 was briefly overviewed. The accuracy of devices now used in clinical practice in Japan is of sufficient grade. The thresholds for hypertension diagnosis based on ABPM have been determined with international concensus. The evaluation of ABPM data and the clinical indications for ABPM are suggested. Particularly, white-coat hypertension, masked hypertension, nocturnal hypertension, morning hypertension and diurnal blood pressure variation are conditions for which ABPM is very useful for the detection, treatment decision and follow-up. Hypertension treatment would be very much improved by the introduction of ABPM into clinical practice.

    Abstract Intravascular large B-cell lymphoma (IVLBCL) is a distinct disease entity of non-Hodgkin lymphoma which is characterized in the current WHO classification by the selective growth of tumour cells in the lumina of small vessels of various organs. This rare disease entity has a high incidence of central nervous system (CNS) involvement at diagnosis. Although several retrospective analyses indicate that the treatment of this lymphoma has improved in the post-rituximab era, risk of CNS recurrence at 3 years still reaches ~25%. Considering the poor prognosis of IVLBCL patients with CNS recurrence, elucidating the optimal treatment strategies for this serious complication is vital in order to further improve its clinical management. Meanwhile, the efficacy of CNS prophylaxis for specific subtypes of lymphoma, for example Burkitt lymphoma and acute lymphocytic leukemia/lymphoblastic lymphoma, has been established, and several risk factors of CNS relapse for diffuse large B-cell lymphoma (DLBCL) were indicated by previous analyses. Considering that almost all IVLBCL patients have similar risk factors, CNS prophylaxis could also be effective, and thereby give rise to better clinical outcomes, in the treatment of IVLBCL, especially for patients without CNS involvement at initial diagnosis. Intensity regimens for CNS and systemic chemotherapy could be useful for patients with CNS involvement at initial diagnosis. This review describes the current understanding of clinical outcome and CNS involvement in IVLBCL, and discusses the optimal treatment strategy and future perspectives for CNS involvement of this rare lymphoma.
