OBJECTIVE:

To evaluate the clinical outcomes in patients with relapsed or refractory peripheral T-cell lymphoma (PTCL) who had undergone allogeneic hematological stem cell transplantation (allo-HSCT).

METHODS:

From June 2007 to June 2017, the clinical data of PTCL patients who underwent HSCT from eight hospitals were assessed retrospectively.

RESULTS:

There were 23 patients diagnosed as relapsed or refractory PTCL with chemoresistance who underwent allo-HSCT. Among these patients, 18 were identified as progressive disease (PD) status and 5 patients as stable disease (SD) status before allo-HSCT. Seventeen patients received allo-HSCT from matched sibling donor (MSD),2 patients from matched unrelated donor and 4 patients from related haplo-identical donor (HD). After a median follow-up of 29 months, 21 patients survived longer than 28 days after allo-HSCT. Hematopoietic reconstitution was achieved in 20 of the 21 patients. The median time of myeloid and platelet engraftment were+13 (9-22) d and+16(10-38) d, respectively. The 100-d treatment-related mortality rate was 13.1%. Acute GVHD occurred in 11(47.8%) patients at a median time of 22(6-82) d after transplantation. Grade Ⅱ~Ⅳ aGVHD occurred in 6 patients. Chronic GVHD occurred in 10 patients at a median of 7.9 (3.5-27) months. After a median follow-up of 29 months, 13 patients died after HSCT. Four of them died of complications associated with allo-HSCT, and other 9 patients died of the primary lymphoma. The 3-years cumulative overall survival (OS) and progress-free survival (PFS) were 43.03% (95%CI: 29.79-69.16) and 39.13% (95%CI: 23.50-65.14), respectively. No significant difference was found in the 3-year PFS between patients with PD status and SD status before allo-HSCT (P=0.133).

CONCLUSION:

Allo-HSCT can be a promising treatment for relapsed or refractory PTCL with chemoresistance.
