Bone marrow involvement in Hodgkin's disease: the significance of non-infiltrative changes.
We have tried to elucidate the significance of so called non-infiltrative changes in order to find their place in the staging procedure particularly in countries where facilities for elaborate clinical staging are not available. Seventy nine out of 88 patients were classified into 3 groups depending upon the histological findings in their bone marrow trephine biopsies. Bone marrow in Group-I (n = 20) patients was essentially normal. The established criteria of bone marrow involvement were fulfilled in Group III patients (n = 25); while bone marrow in Group-II patients (n = 34) showed non-infiltrative changes. The clinical presentation, peripheral blood parameters and LDH levels of the 3 groups of patients were compared. There was progressive anaemia, neutrophilic leucocytosis and increase in ESR from Group I to III. The change was statistically significant when Group I was compared with Group II or Group III but non-significant when Group II was compared with Group III. It is, therefore, postulated that both Groups II and III reflect the bone marrow involvement although the changes observed in Group II do not satisfy the previously established criteria for this purpose.
