Segmental Insights

Therapy Insights

Based on the Therapy, allogeneic HSCT is currently the dominant approach over autologous HSCT due to a combination of disease-specific factors, donor availability, and advancements in transplant techniques. Allogeneic HSCT involves using stem cells from a healthy donor, which can be a relative or an unrelated individual. This method is particularly effective for treating aggressive hematological malignancies such as leukemia, lymphoma, and myelodysplastic syndromes. The primary advantage of allogeneic HSCT lies in the graft-versus-leukemia (GVL) effect, where the donor’s immune cells attack residual cancer cells, reducing the risk of relapse. This immunological benefit is crucial for high-risk or relapsed cancers, making allogeneic HSCT a preferred choice for these conditions. Autologous HSCT, which utilizes the patient’s own stem cells, is typically used for diseases like multiple myeloma and some types of lymphoma. However, it lacks the GVL effect, which limits its efficacy for certain high-risk hematological malignancies. For patients with more aggressive or relapsed diseases, the lack of this additional therapeutic benefit makes allogeneic HSCT a more favorable option.

The availability of suitable donors significantly influences the preference for allogeneic HSCT in Japan. The country boasts a well-established stem cell donor registry, supported by organizations such as the Japanese Bone Marrow Donor Program. This registry facilitates the identification of compatible donors for allogeneic transplants, providing a crucial resource for patients in need of a donor. In contrast, autologous HSCT relies on the patient’s ability to collect and preserve their own stem cells, which can be challenging for those with advanced disease or poor health.

• According to an article titled,“Eculizumab treatment in paediatric patients diagnosed with aHUS afterhaematopoietic stem cell transplantationa HSCT-TMA case series from JapaneseaHUS post-marketing surveillance”, Hematopoietic stem cell transplantation(HSCT)-associated thrombotic microangiopathy (HSCT-TMA) is a severecomplication with a high mortality rate. Increasing evidence indicates thatcomplement dysregulation may play a role in the development of HSCT-TMA. Weconducted a retrospective analysis of thirteen pediatric patients diagnosedwith atypical hemolytic uremic syndrome who were treated with eculizumab tomanage HSCT-TMA during post-marketing surveillance in Japan. The medianinterval from HSCT to the onset of TMA was 31 days (Interquartile range, IQR;21–58 days), and the median number of eculizumab doses administered was three(IQR; 2–5). At the last follow-up, seven patients (54%) were still alive, whilesix had died due to HSCT-related complications. Of the seven survivors, six hadstarted eculizumab after an inadequate response to plasma therapy. Eculizumabtreatment resulted in significant improvements in median platelet counts andLDH levels in all surviving patients, with renal function improving in 4 out of7 cases. All survivors had potential risk factors for complementoveractivation. No recurrence of TMA was observed during the follow-up periodafter eculizumab was discontinued (median; 111.5 days, IQR; 95–555 days). Thisanalysis suggests that eculizumab was beneficial for more than half of thepediatric patients studied. Ongoing clinical trials are anticipated to refinethe treatment regimen for terminal complement pathway inhibitors, potentiallyestablishing them as a viable therapeutic option for pediatric HSCT-TMA in thefuture.
• According to an article titled,“Outcome of allogeneic hematopoietic stem cell transplantation for follicularlymphoma relapsing after autologous transplantationanalysis of the JapanSociety for Hematopoietic Cell Transplantation”, Autologous stem celltransplantation (SCT) is a well-established treatment for patients withrelapsed and refractory follicular lymphoma (FL); however, more than half ofthese patients experience relapse.
