Bilateral trephine bone marrow biopsies in Hodgkin's and non-Hodgkin's lymphoma

Abstract

This study was undertaken to investigate the usefulness of bilateral rather than unilateral iliac trephine biopsies in demonstrating Hodgkin's disease and non-Hodgkin's lymphoma in the bone marrow. One hundred and seventy adequate bilateral biopsies were obtained from 145 patients. Among 76 bilateral trephine biopsies from 65 patients with Hodgkin's disease, tumour was found bilaterally in 3 cases and on only one side in 2 cases. Among 94 bilateral biopsies from 80 patients with non-Hodgkin's lymphoma, tumour was found bilaterally in 17 cases and on only one side in 12. Considering all of the cases in the series, the performance of bilateral biopsy increased the yield of positive marrows from an estimate of 27 to 34, an increase of 26%. We conclude that bilateral trephine biopsy is superior to unilateral biopsy for the demonstration of bone marrow involvement by Hodgkin's disease or non-Hodgkin's lymphoma and recommend that bilateral trephine biopsies be performed when a knowledge of the state of the bone marrow is important for clinical decision making.
