Use of ifosfamide, carboplatin and etoposide in combination with brentuximab vedotin or romidepsin based on CD30 positivity in relapsed/refractory peripheral T-cell lymphoma.

Background: Relapsed/refractory peripheral T-cell lymphoma (R/R PTCL) has a poor prognosis. Romidepsin (Ro) and brentuximab vedotin (Bv), combined with ifosfamide, carboplatin, and etoposide (ICE) has not been significantly studied in PTCL.

Aim: We report outcomes of Bv-ICE in CD30 (+) and Ro-ICE in CD30 (-) R/R PTCL treated in "Blinded for peer review" Cancer Center.

Methods And Results: We retrospectively identified R/R PTCL patients treated with BV-ICE or romidepsin-ICE from May 2016 to September 2019. Out of 13 R/R PTCL patients, 6 were treated with Bv-ICE and 7 with Ro-ICE. Bv-ICE had an overall response rate (ORR) of 66.7%, with all the patients achieving a complete response. ORR was 71.4% for Ro-ICE with 57.1% of patients achieving a complete response. Two patients treated with Bv-ICE and three treated with Ro-ICE received transplantation.

Conclusion: In our experience, treatment with Bv-ICE and Ro-ICE based on CD30 positivity is feasible and effective to treat patients with R/R PTCL.
