Bone involvement in Hodgkin's disease.

Eighteen patients with osseous involvement were identified from a series of 124 consecutive patients treated with combined-modality therapy with advanced-stage or relapsing Hodgkin's disease. Multiple lesions were seen as frequently as were solitary lesions. Nodular sclerosing histology was as prevalent as mixed cellularity disease. However, those five cases initially diagnosed at protocol entry were predominantly mixed cellularity (80%) with multiple lesions (80%). Sites of involvement included: the spine, 24; pelvis, 8; ribs, 4; femur, 3; skull, 1; and shoulder 1. Actuarial survival for these patients was 84% at nine years. Only three patients were induction failures and no patient has had a relapse. Patients with bone lesions had favorable responses to combined-modality therapy.
