简要总结
To evaluate, through a prospective multicenter observational study, autologous or allogeneic hematopoietic stem cell transplantation (Auto-SCT/allo-SCT)as consolidation therapy in subjects with T lymphoblastic leukemia/Lymphoblastic lymphoma(T-ALL/LBL)who have achieved first complete remission (CR). Assess relapse-free survival (RFS), overall survival (OS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM) among different treatment regimens
详细描述
This prospective, multicenter cohort study enrolls patients with T-lymphoblastic leukemia/lymphoma in first complete remission (CR1) to investigate the efficacy and safety of autologous versus allogeneic hematopoietic stem cell transplantation as consolidation therapy. At screening/baseline, informed consent is obtained and inclusion/exclusion criteria are checked. The planned enrollment is 84 patients per group. Data collection includes demographics, medical history, vital signs, physical examination, laboratory tests (cranial MRI with contrast, PET-CT, routine blood and urine tests, liver and kidney function, routine CSF analysis, biochemistry, abnormal cells), pregnancy tests for female patients, and other necessary auxiliary examinations.

排除标准
- •Malignancies other than acute T-lymphoblastic leukemia, T-cell lymphoma, or T-lymphoblastic lymphoma within 5 years prior to screening, except for adequately treated cervical carcinoma in situ, basal cell or squamous cell skin cancer, localized prostate cancer after radical surgery, ductal carcinoma in situ after radical surgery, or thyroid cancer after radical surgery.
