Bone marrow examination in Hodgkin's disease.

Bone marrow aspiration and biopsy was performed as part of routine staging in 425 patients with primary Hodgkin's disease. Only seven patients were found to have bone marrow disease by biopsy and only four by aspiration. All these patients had B symptoms and stage III or IV before bone marrow examination. Bone marrow infiltration did not influence treatment decision and there was no association between bone marrow findings and outcome of the disease.
