Samenvatting

Purpose: In classical Hodgkin's lymphoma (cHL), the impact of tumor cell Epstein-Barr virus (EBV) status on clinical outcome is controversial. Patients and Methods: We assessed failure-free survival (FFS) and relative survival (RS) in 412 patients with cHL and age-defined subgroups in a population-based study in the northern Netherlands. Tumor cell EBV status was positive in 34%, and the median follow-up time was 7.1 years. Patients' median age at diagnosis was 35 years (range, 7 to 91 years), and 63% had Ann Arbor stage I or II, 24% had stage III, and 12% had stage IV disease. Results : EBV status influenced 5-year FFS and RS only in patients from the age group 50 to 74 years. Five-year FFS was 60% in patients with EBV-positive versus 85% in EBV-negative tumors (P = .01). Five-year RS was 69% in patients with EBV-positive versus 82% in EBV-negative tumors (P = .03). After adjusting for histology, HLA class II expression by tumor cells, stage, presence of extranodal localizations and treatment, and the effect of positive EBV tumor status remained significant in FFS multivariate analysis (hazard ratio, 3.11; 95% CI, 1.28 to 7.53; P = .01). Conclusion : This study indicates that treatment failure in older adult patients with cHL is associated with positive tumor cell EBV status.
