Seven patients (50.0%) developed a grade 3 or greater infection following VEN therapy, and 3 patients (21.4%) developed a grade 3 or greater intracranial hemorrhage. Three patients experienced early death within 30 days of therapy (2 from infection, 1 from bleeding). The median overall survival (OS) was 4.7 months, and the 1-year OS rate was 23.6% (95% CI 4.4-51.2) for the entire patient cohort. Overall, the response rate was not inferior to that with conventional salvage chemotherapy, but there were notable complications as a result of prolonged cytopenias. AIM Large granular lymphocyte leukemia (LGLL) is a rare lymphoproliferative disorder associated with failure of hematopoiesis and autoimmune diseases. This study describes the clinical features and treatment responses of 108 patients with T-cell large granular lymphocyte leukemia (T-LGLL). METHODS Clinical data were collected from T-LGLL patients treated at an anemia treatment center within the hematology and blood diseases unit of a single hospital from January 2009 to April 2019. RESULTS The majority of patients (78 %) were symptomatic at the time of presentation. Splenomegaly was observed in 41 % of cases, while hepatomegaly and lymphadenopathy were rare (6 % and 7 %, respectively). Cyclosporine (CsA) monotherapy was used as first-line therapy for 16 patients, with an overall response rate (ORR) of 56 %. CsA in combination with steroids was administered in 83 patients, with an ORR of 48 %. Among patients experiencing relapse or resistance to first-line therapy, 10 received antithymocyte globulin (ATG) therapy, with an ORR of 50 %; an additional 9 patients received a modified regimen of high-dose cyclophosphamide (CTX) therapy, yielding an ORR of 78 %. CONCLUSIONS This study provides new information regarding th
