title: Elevated pretreatment serum levels of Il-10 are associated with a poor prognosis in Hodgkin's disease, the milan cancer institute experience.
abstract: Alterated cytokine secretion may play a role in determining Hodgkin's disease-related immunosuppression. The aim of this study was to analyze the clinical significance of interleukin-10 (IL-10) serum levels in 73 chemotherapy-naive patients with Hodgkin's disease. We evaluated the relationship between pretreatment circulating values of IL-10 and both the clinical characteristics of the disease as well as the prognosis in terms of freedom from progression and overall survival. Abnormally high pre-treatment serum levels (mean+/-standard error: 26.79+/-13.24 pg/ml) were detected in 33/73 (45%) patients. The percentage of patients with enhanced IL-10 secretion was significantly higher in the presence of advanced disease (56% vs 32%, P<0.03), systemic symptoms (57% vs 34%, P<0.04) and more than 3 involved sites (61% vs 36%, P<0.03). The high basal levels of IL-10 negatively influenced long-term results: at 8-years freedom from progression (FFP) and overall survival (OS) for patients with IL-10>6 pg/ml vs</=6 pg/ml were 69% and 76% vs 97. 5% and 95%, respectively. The multivariate analysis confirmed the prognostic value of IL-10 basal serum levels (FFP, P=0.0001; OS, P=0. 06). Our study suggests that high pre-treatment circulating levels of IL-10 are associated with a poor prognosis, irrespective of other common prognostic variables.
