T-cell lymphomas represent rare and heterogeneous group of aggressive non-Hodgkin lymphomas. Almost 70% of patients undergoing first-line therapy develop a relapse or refractory disease. There are currently no standards for the treatment of relapsed/refractory T-cell lymphomas (r/r TCL). A number of novel therapy approaches are aimed for improvement of outcomes in patients with r/r TCL. This report summarizes the First I. Pavlov State Medical University experience in the treatment of patients with T-cell lymphomas.

Patients and methods

We analyzed data of 42 patients with TCL eligible for stem cells transplantation treated in First Saint-Petersburg state medical University from 2005 to 2019. Among them n=10 with anaplastic large cell lymphoma (ALK+), n=3 with anaplastic large cell lymphoma (ALK-), n=4 with angioimmunoblastic T-cell lymphoma, n=4 with hepatosplenic T-cell lymphoma, n=1 with γδ-T cell lymphoma, n=17 with PTCL not otherwise specified (PTCL-NOS), n=1 with mycosis fungoides (MF), n=1 with primary cutaneous CD4+ T-cell lymphoma and n=1 with subcutaneous panniculitis-like T-cell lymphoma (SPTCL). The median age was 43 years (range 1 – 72 years).

Median time from initial diagnosis to relapse or progression after primary therapy was 1.3 months (0-61.6). Among them, 23 patients (55%) had a primary chemoresistant disease, while other patients (n=18, 43%) had a relapse after initial treatment. The treatment was tailored according to biological factors presented in patients. In eight patients with CD30+ PTCL, brentuximab vedotine was used. One patient with ALK+ anaplastic lymphoma received ALK inhibitor crizotinib. In three patients with PD-L1 hyperexpression, nivolumab treatment was applied. The responses were consolidated with hematopoietic stem cells transplantation (HSCT). Overall 23 patients underwent SCT: high-dose chemotherapy with autologous hematopoietic SCT was performed in 16 patients, 12 patients were subject to allogeneic SCT (among them, 5 patients with relapses after auto-SCT).


At the time of analysis, 32 patients remained alive. The median follow-up of surviving patients was 38 months (7-124 mo). The median overall survival was not reached, and the 3-year survival rate was 68%. The disease status at the last follow-up was complete remission (CR) in 11 patients, partial response in 3 patients, and disease progression in 21 cases. Among different factors, lower ECOG performance status at the time of diagnosis was significantly associated with adverse prognosis (p=0.05). Patients that had undergo salvage SCT showed significantly better disease status at the moment of last follow-up: 15/18 (83%) were in CR, versus 3/14 (21%) in the patients who did not undergo SCT. Progression-free survival rate was 43% for the patients with T-cell lymphoma after salvage SCT.


The results of analysis show that introduction of novel agents and consolidation with high-dose chemotherapy and autologous stem cells transplantation, or allogeneic stem cells transplantation in selected cases, may improve outcomes in patients with relapsed and refractory T-cell lymphomas. Brentuximab vedotine-based regimens may be successfully used as a bridge therapy before stem cells transplantation.
