OBJECTIVE: To investigate the therapeutic efficacy of allogeneic peripheral blood hematopoietic stem cell transpdantation (allo-HSCT) for T lymphoblastic lymphoma (T-LBL).
METHODS: The clinical data of 14 adult patients with T-LBL treated with allo-HSCT were collected, the hematopoietic reconstruction, survival and relapse, as well as overall survival (OS) rate, event-free survival (EFS) rate of 1, 3 and 5 years were analysed retrospectively.
RESULTS: All the patients were engrafted with neutrophil successfully, the median time of absolute neutrophil count >0.5 × 10(9)/L was 13 (10-19) d; 13 patients were engrafted with platelets successfully, the median time of Plt count >20 × 10(9)/L was 17 (12-62) days. The acute GVHD occurred in 6 patients, but among them only 1 case with 3 grade of aGVHD; out of 14 patients, 5 developed chronic GVHD. The transplant-related mortality at 100 days was 7.1% (1/14), mainly from coronary heart disease and pulmonary infection. The median follow-up time was 26.5 months, the estimated 1, 3 and 5 year OS rate was 85.7%, 47.6% and 38.1%, respectively, and estimated 1, 3 year EFS rate was 85.7%, 34.4% and 34.1%, respectively. The relapse rate was 42.8% (6/14) and the median relapse time was 22.5% months after transplantation. Up to now, 7 patients still survive, 1 patient out of them have survived for 103 months.
CONCLUSION: The allo-HSCT is a safe and effective method for treatment of T-LBL.
