The activity of cobalt-activated acylase was determined in the serum of mice with transplantable leukemia (P 388, L 1210 standard, L 1210/ara-C, L 1210/CH3-G, plasmocytoma ADJPC-5, lymphoma AKSL-4 and natural leukemia in mice NZB). A statistically significant increase in enzyme activity in all leukemias except lymphatic leukemia has been demonstrated. The results suggest possibility of using the enzymatic measurement as a marker of transplantable leukemia in mice.

Purpose: Asparaginase (ASN) is a critical component of pediatric ALL protocols. Until recently, ASN was available in three formulations: native Escherichia coli, PEGylated E. coli (PEG), and Erwinase, with native E.

Previous studies reported higher rates of post- hematopoietic stem cell transplant (HSCT) hepatic sinusoidal obstruction syndrome (SOS) in patients receiving InO versus chemotherapy prior to HSCT. It is unknown if a lower InO dose would reduce risk of post-HSCT SOS or if it would impact efficacy.

Methodological advancements now allow older adults with AML to receive allografts although conflicting data exist regarding relative outcomes across age groups and benefits of different conditioning intensities. We retrospectively analyzed 495 adults aged 60-64 (n = 184), 65-69 (n = 189), or ≥70 (n = 122) allografted for AML in remission at our institution from 2006 to 2023. There were no significant differences in relapse or relapse-free survival (RFS) among the 3 age cohorts after multivariable adjustment.

CD7-targeted chimeric antigen receptor-T (CAR-T) cell therapy has shown great promise in the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL). In this study, we reported a case of a 34-year-old male patient with T-ALL who finally developed multi-line drug resistance and refractoriness after multiple lines of high-intensity chemotherapy. After physician evaluation, this patient received allogeneic hematopoietic stem cell transplantation (allo-HSCT).
