Abstract

Purpose

The aim of this study was to assess the prognostic factors of peripheral T-cell lymphoma, unspecified (PTCL-U).

Patients and methods

We retrospectively analyzed 30 cases fulfilling the criteria of PTCL-U defined by the World Health Organization classification. The patients were treated with 6–8 cycles of a CHOP or THP (pirarubicin)-COP regimen.

Results

A high serum sIL-2R level (≥2,000 U/ml) at onset was associated with a low complete remission rate. Patients with high sIL-2R had significantly lower survival rates (5 year, 15.1%) than those with low sIL-2R (<2,000 U/ml) (100%) (P < 0.005). Factors associated with worse overall survival in a univariate analysis were high sIL-2R (P < 0.005), high age (>60 years) (P < 0.05), poor performance status (P < 0.01) and poor international prognostic index (P < 0.05). No correlation was observed between sIL-2R and other markers. Multivariate analysis showed that only sIL-2R was a prognostic factor for overall survival (P < 0.01).

Conclusion

The results suggest that a high serum sIL-2R level predicts a poor prognosis in PTCL-U.
