Immuno-checkpoint inhibitors are one of the most promising immunotherapies for various advanced cancers including hematologic malignancies. Recently, enhanced signaling of the PD-1/CTLA4 pathway has emerged as a critical mechanism by which tumors can escape the anti-tumor immune response. ⋯ Currently, several clinical trials including single agent or combination therapies for hematologic malignancies, such as Hodgkin lymphoma, B-cell lymphomas and multiple myeloma, are ongoing. The results of ongoing and future clinical trials may establish a new treatment paradigm for hematologic malignancies.

Acquired bone marrow failure syndromes consist of aplastic anemia, paroxysmal nocturnal hemoglobinuria (PNH), and myelodysplastic syndromes (MDS). Clonal hematopoiesis is frequently observed in non-neoplastic disorders, aplastic anemia and PNH as well as a neoplastic phenotype, MDS. ⋯ Recent advancements in next generation sequencing technology have revealed a diverse clonal structure in these bone marrow failure syndromes, as well as in age-related clonal hematopoiesis in healthy people. In this review article, we describe gene mutations in bone marrow failure syndromes, together with those detected in healthy people.

In the past decade, previously approved novel agents, such as proteasome inhibitors (bortezomib) and immunomodulatory drugs ([IMiDs]; e.g., lenalidomide), have led to significant improvement in the treatment of multiple myeloma in Japan. However, almost all patients will ultimately relapse, even when they have achieved a deep and prolonged therapeutic response with initial treatment. Next-generation IMiDs (pomalidomide) and deacetylase inhibitors (panobinostat) were approved for use as salvage therapy for refractory and relapsed multiple myeloma [RRMM] within the last year. ⋯ Therefore, relapse management requires an individual approach based on assessments of patient-, disease-, and treatment-related factors. The primary considerations when selecting an appropriate treatment are patient-related factors such as frailty, comorbidity, disability, quality of life, and the overall goals of care. We hope that these novel agents that appear promising in Japan, such as monoclonal antibodies (e.g., elotuzumab, daratumumab) and next-generation proteasome inhibitors (e.g., carfilzomib, ixazomib) will improve the outcomes of patients with this incurable disease in the near future.

The inherited bone marrow failure syndromes (IBMFS) are rare disorders in which there is usually some form of bone marrow failure and typical changes in physical appearance, associated with a family history of the same disorder. Patients with IBMFS have a very high risk of developing myelodysplastic syndrome, acute myeloid leukemia, and solid tumors. ⋯ In this section, we describe physical and laboratory findings and management of the major IBMFS: Fanconi anemia, dyskeratosis congenita, Shwachman-Diamond syndrome, and Diamond Blackfan anemia. We also discuss their possible implications in the clinical features of Japanese patients.

With improvement of survival owing to the recent implementation of new anti-myeloma (MM) agents, bone management will become more important for maintaining the quality of life (QoL) of patients. Bisphosphonates are currently the standard of care for MM-related bone disease. Zoledronic acid is recommended for newly diagnosed MM patients receiving front-line anti-MM treatment regardless of existing detectable bone lesions. ⋯ Bisphosphonates but not denosumab deposit in bone with a long half-life, which may make a difference in long-term efficacy as well as adverse effects. Clinical benefits of long-term anti-resorptive therapies after achieving a good response should be clarified, in order to avoid the emergence of severe complications. Impacts of new agents in combination with these anti-resorptive agents on bone metabolism have yet to be studied.
