Abstract


Background: Salvage chemotherapy is the mainstay for the treatment of relapsed/refractory peripheral T-cell lymphomas (R/R PTCLs). ESHAP regimen, consisting of etoposide, methylprednisolone, high-dose Ara-C, and cisplatin is considered one of the well-accepted regimens for R/R lymphoma. Though, the evidence of long-term efficacy of ESHAP on R/R PTCLs is limited. This study aims to determine the efficacy and safety of ESHAP as a first salvage regimen, not followed by autologous stem cell transplantation (ASCT), in R/R PTCLs.

Methods: Patients with PTCLs, who progressed after one prior therapy and received ESHAP as a salvage treatment without subsequent ASCT, were recruited from the prospective observational study in the patients with lymphoma.

Results: From January 2005 to April 2015, 33 patients with R/R PTCLs received ESHAP as first salvage regimen at Chiang Mai University Hospital. The overall response rate was 46% (complete remission (CR) 39%). The median duration of response was 18 months. Median second progression-free survival (PFS) and overall survival (OS) were 8.0 and 11.0 months, respectively. Patients having late relapse had more favorable OS than those having early relapsed or refractory disease with a median OS of 21, 17 and 3 months, respectively (P = 0.001). Patients achieving CR after ESHAP had significantly better median OS (39, 7 and 5 months, P < 0.0001) and second PFS (33, 2 and 2 months, P < 0.0001) than those achieving PR or having progressive disease. Grade 3-4 neutropenia (45.5%) and thrombocytopenia (33.4%) were common but manageable.

Conclusions: ESHAP offers a long-term survival in some transplant ineligible patients with PTCLs who were chemosensitive with late relapse after front-line therapy. These results require further investigation in a prospective study.
