Interim positron emission tomography (iPET-2)-guided therapy following two cycles of ABVD chemotherapy has been developed for newly diagnosed classical Hodgkin lymphoma (cHL) patients in several prospective trials. In localized-stage cHL, radiotherapy cannot be omitted, even in iPET-negative patients after two or three cycles of ABVD, whereas two cycles of escalated BEACOPP regimens followed by involved nodular radiotherapy (30 Gy) is a useful treatment option for iPET-2 positive patients after two cycles of ABVD. In advanced-stage cHL, approximately 20% of cases were iPET-2 positive, and the switch to BEACOPP-based regimens was reported as a useful treatment option, with 3-year progression-free survival of approximately 60-65%, in iPET-2-positive patients in three clinical trials. Furthermore, the switch to AVD (omission of bleomycin after two cycles of ABVD) is a reasonable treatment option in iPET-2-negative patients, particularly those at risk for bleomycin lung toxicity in advanced-stage cHL. This review summarizes the current evidence regarding interim PET-guided therapy for newly diagnosed cHL patients.With pediatric-inspired chemotherapy, the survival of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL) has improved. For standard-risk patients in the first complete remission (CR1), pediatric-inspired chemotherapy may be superior than allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, increased dose of steroid, vincristine, and L-asparaginase (L-Asp) in pediatric-inspired chemotherapy induces adverse events in certain number of adult ALL patients. Especially, the administration of L-Asp is often reduced to 60-70% for thrombosis or liver dysfunction. The optimal dose of these agents for adult ALL patients with higher age is under investigation. Moreover, minimal residual disease (MRD) >10-4 is a poor prognostic factor. The time point for the assessment of MRD should be defined. For relapsed or refractory ALL, inotuzumab ozogamicin and blinatumomab are promising antibody agents that diminish MRD and proceed to allo-HSCT.The introduction of imatinib (IM) has led to a paradigm shift in the treatment strategy for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL). After introducing IM, second- and third-generation tyrosine kinase inhibitors (TKIs), which have stronger BCR-ABL1 inhibitory activity than IM, have appeared and their therapeutic results are beginning to be reported. However, to date, no comparison study between individual TKI and the current treatment strategy for Ph + ALL has been performed considering either a TKI-based regimen in induction followed by combination chemotherapy with a TKI or allogeneic hematopoietic stem cell transplantation (alloSCT). In the case of treating with ponatinib, it was suggested that the inclusion of alloSCT into the treatment strategy could be avoided. Because alloSCT has an appreciable treatment-related mortality rate and an upper age limit, the treatment strategy without alloSCT may remain mainstream in the future. Chemotherapy-free treatments, such as a TKI plus a monoclonal antibody or immunotherapy, are also expected to gain traction an alternate strategy and are now under investigation.Myelodysplastic syndromes (MDS) are malignant clonal stem cell disorders. There are two main treatment options for higher-risk MDS, i.e., eligible and ineligible hematopoietic stem cell transplantation (HSCT). Transplantation-eligible patients should receive HSCT immediately, with or without prior therapy. In contrast, for patients who are ineligible for HSCT, azacitidine (AZA) may now be the first choice of treatment, which significantly prolongs overall survival in responder patients when compared with conventional care regimens. However, there are major problems regarding the management of patients with disease relapse after HSCT and those with loss of response to AZA. In this review, treatment strategies and future perspectives, including the use of novel agents, are presented with the aim of improving the outcome of higher-risk MDS.Myelodysplastic syndromes (MDS) are neoplastic diseases of the hematopoietic stem cells, caused by genetic mutations. The clinical courses of MDS are highly variable based on the underlying genetic aberrations, ranging from slowly progressing cytopenia to rapidly-manifesting fatal diseases, including the development of acute myelogenous leukemia. The management of lower-risk MDS, which is risk-stratified based on the revised International Prognostic Scoring System (IPSS-R), mainly consists of a supportive therapy, including blood transfusion to treat anemia and thrombocytopenia. Recently, three novel drugs were approved, which became available in Japan. These include darbepoetin alfa, an erythropoiesis-stimulating agent; lenalidomide, which is specifically active for anemia of 5q- syndrome; and deferasirox, an oral iron-chelating agent. Decision analyses also provide evidence in determining the optimal timing for the potentially curative allogeneic hematopoietic stem cell transplantation for lower-risk MDS. Thus, the management of lower-risk MDS should be optimized using these novel agents and newly available evidence.Frequent packed red blood cell (pRBC) transfusion can cause transfusional iron overload. read more Excess iron generates reactive oxygen species and provokes organ dysfunction. In lower-risk myelodysplastic syndrome (MDS), hyperferritinemia is known as one of the negative prognostic factors. Thus far, iron chelation therapy (ICT) is the only effective treatment for chronic iron overload induced by transfusion. Transfusional iron overload is diagnosed when serum ferritin (SF) levels are ≥500 ng/ml and cumulative volume of pRBC transfusion is ≥20 JPN units. ICT should be initiated when SF levels are ≥1,000 ng/ml and will be further continued until SF levels decline to less then 500 ng/ml. ICT serves to ameliorate organ dysfunction. A prospective study demonstrated that in patients with lower-risk MDS, ICT can reduce the risk of combined events, including cardiac events, hepatic events, AML transformation, and death of any cause. In some patients, hematological improvement will be observed. However, clinical features underling this hematological phenomenon are not fully understood.
