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
Age 14-55 years, no gender restriction
Expected survival >12 weeks
ECOG performance status 0-2
Pathologically or by bone marrow flow cytometry confirmed •T-lymphoblastic lymphoma in first complete remission (CR1) after chemotherapy; CR1 criteria: first complete remission, defined as: ① For intramedullary disease, meeting the CR criteria of the 2024 Chinese Adult Acute Lymphblastic Leukemia Diagnosis and Treatment Guidelines (2024 edition) with flow cytometric/gene testing showing MRD negativity; ② For extramedullary disease, meeting the Lugano 2014 response criteria for CR with a PET-CT score of 1-2
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.

Dysfunction of vital organs (cardiovascular, cerebrovascular, pulmonary);history of active gastrointestinal bleeding within the past 3 months; uncontrolled hypertension or history of hypertensive crisis or hypertensive encephalopathy; history or evidence of major cardiovascular risk, including any of the following: congestive heart failure, unstable angina, clinically significant arrhythmias (e.g., ventricular fibrillation, ventricular tachycardia); history of arterial thrombosis within the past 3 months (e.g., stroke, transient ischemic attack); history of symptomatic deep vein thrombosis or pulmonary embolism within the past 6 months, or history of coronary angioplasty, defibrillation, or any clinically relevant complication or disease that may pose a risk to subject safety or interfere with study assessments, procedures, or completion.
Any other uncontrolled active disease that precludes participation in the trial.
