Peripheral T-cell lymphomas (PTCL) are a group of rare, aggressive non-Hodgkin’s lymphomas originating from mature T-lymphocytes and characterized in most cases by refractory or relapsed disease course after standard therapies. We carried out retrospective a multicenter analysis of the treatment of patients with PTCL focusing on the transplantation methods of treatment.

Patients and methods

151 patients with PTCL were included who were treated in 5 clinical centers in Russia and Kazakhstan from 2005 to 2021. The most common histological variants were PTCL, NOS (n=51); anaplastic large cell lymphomas (ALCL), ALK+ (n=1); ALCL, ALK- (n=26); angioimmunoblastic T-cell lymphoma (n=24). The rest of the patients (n=29) had more rare forms of PTCL. The median age was 46 years (1-76). Of 151 patients, 94 (62%) had a primary refractory disease, 32 (21%) developed a relapse after the first line of therapy. 39 patients at different stages of treatment underwent autologous hematopoietic stem cell transplantation (auto-HSCT): 10 received auto-HSCT as a consolidation of the 1st line of therapy, 20 – after the 2nd line, 8 – after the 3rd line of therapy. At the time of auto-HSCT, all the patients were in complete (CR) or (PR) partial remission. Allo-HSCT was performed in 19 patients with a more aggressive. Allo-HSCT as a 1st transplant was performed in 14 patients. Allo-HSCT was performed in 5 patients with auto-HSCT failure.


77 patients were alive at the time of analysis. Median follow-up was 35 months (1-277). The median overall survival (OS) was not reached; the 3-year survival rate was 54%. The median progression-free survival (PFS) was 4 months, the 3-year PFS of the entire group of patients is 16%. Patients who failed HSCT had a worse prognosis (3-year OS 45%) compared to patients who underwent auto-HSCT (3-year OS 55%) or allo-HSCT (3-year OS 71%). 3-year PFS after auto-HSCT and allo-HSCT – 24% and 55%, respectively. It was revealed that patients who received auto-HSCT as the 1st line of therapy had better prognosis comparing to patients who received auto-HSCT in second and subsequent lines of therapy. We also obtained data that the patients who underwent allo-HSCT in PR or CR have an advantage over patients who underwent allo-HSCT, when stabilization or progression of the disease was achieved (3-year OS 84% vs 25%).


Our data provide additional evidence that allo- and auto-HSCT are effective treatments for patients with PTCL. If a response is achieved, 1st line auto-HSCT is the preferred clinical option in most PTCL types. Allo-HSCT, when performed in PR or PR in case of refractory or recurrent course of the disease was associated with better prognosis for PTCL patients.
