We studied by immunohistochemistry CD68 + tumor-associated macrophages (TAMs) and angiogenesis in 121 consecutive cases of uniformly treated classical Hodgkin lymphoma (cHL). High TAM count showed a significant correlation with age >= 45, mixed cellularity subtype and high beta(2)-microglobulin level. Vessel density (VD) was unrelated to clinicopathological features, while a significant correlation was found between TAM count and VD. Patients with high TAMs showed a trend toward reduced progression-free survival and significantly shorter overall survival (OS). No correlation was found between VD and survival. At multivariate analysis, bulky disease was an independent predictor of reduced progression-free survival, while independent adverse prognostic factors for OS were male sex, age >= 45, advanced stage and bulky disease. High TAM count results in an adverse overall outcome in cHL and is significantly correlated to VD. Since VD has no prognostic relevance, the adverse effect of TAMs is presumably unrelated to angiogenesis.
