Abstract

Background Classical Hodgkin’s lymphoma is characterized by Hodgkin and Reed Sternberg cells, which are of B-cell origin in many cases. We recently highlighted the adverse prognostic significance of cytotoxic molecule expression in patients with classical Hodgkin’s lymphoma. However, the clinical characteristics of cytotoxic molecule-positive classical Hodgkin’s lymphoma remain controversial. Design and Methods We investigated the clinicopathological profiles of 32 patients with cytotoxic molecule-positive Hodgkin’s lymphoma, comprising 23 with nodular sclerosis and 9 with mixed cellularity, and compared these profiles with those of 55 patients with cytotoxic molecule-positive nodal peripheral T-cell lymphoma, not otherwise specified and 439 patients with cytotoxic molecule-negative Hodgkin’s lymphoma. Results The patients with cytotoxic molecule-positive Hodgkin’s lymphoma consisted of 20 men and 12 women with a median age of 50 years (range, 19 to 81). All these patients had lymphadenopathy at presentation, and 14 showed mediastinal involvement. Physical findings included hepatomegaly and splenomegaly in six patients each. Four patients had a bulky mass, and nine showed stage IV disease. The tumor cells of patients with cytotoxic molecule-positive Hodgkin’s lymphoma had a prototypic immunophenotype of CD15+ CD30+ CD45RO− fascin+, with positivity for Epstein-Barr virus in 39% of cases. All patients were negative for Pax5. In comparison with patients with cytotoxic molecule-positive nodal peripheral T-cell lymphomas, not otherwise specified, patients with cytotoxic-positive Hodgkin’s lymphoma had relatively mild clinical symptoms, similar to those of patients with cytotoxic molecule-negative Hodgkin’s lymphoma. Regarding prognosis, the survival of patients with cytotoxic molecule-positive Hodgkin’s lymphoma was worse than that of patients with cytotoxic molecule-negative Hodgkin’s lymphoma ( P =0.0003) but better than that of patients with cytotoxic molecule-positive peripheral T-cell lymphomas, not otherwise specified ( P =0.002). Conclusions Cytotoxic molecule-positive Hodgkin’s lymphoma is characterized by an unfavorable prognosis, even if its clinicopathological features are within the boundaries of classical Hodgkin’s lymphoma. More effective chemotherapy for cytotoxic molecule-positive Hodgkin’s lymphoma is clearly required.
