Objective : To define the prevalence of CD30 expression and the relationship to survival in patients with peripheral T-cell lymphoma (PTCL).
Materials and Methods : A 12-year retrospective study of 135 PTCL patients was completed. Their tissue specimens were stained for CD30 antibody and the results were correlated with clinical data and survival.
Results : One hundred thirty-five patients were enrolled. The subtypes of PTCL were classified as PTCL-NOS (36.3%), nasal NKTCL (17.8%), AITL (15.6%), CTCL (13.3%), SPTCL (11.1%), ALCL (4.4%), C-ALCL (0.7%), and EATL (0.7%). The expression of CD30 in the PTCLs was 34.8%, which significantly associated with histological subtypes (p<0.001). There was a higher prevalence in ALCL or C-ALCL (100.0%), nasal NKTCL (79.2%), and PTCL- NOS (30.6%). The median survival was 25 months with a projected 5-year survival of 37.0%. CD30 positivity was significantly associated with poor survival outcome (CD30⁻ 30 months versus CD30⁺ 14 months, p=0.013). From Cox regression analysis, PTCL subtypes were independent prognostic predictor for survival in the present study.
Conclusion : The expression of CD30 in PTCLs was demonstrated in one-third of patients and was associated with histological subtypes and inferior survival outcome.
