The reticulin content of bone marrow in acute leukaemia in adults

Abstract

Marrow reticulin was studied by trephine biopsy in 44 patients with adult acute leukaemia at presentation and subsequently during the course of their illness. The findings indicate that: (1) an increase in marrow reticulin is common at presentation in patients with both acute lymphoblastic and acute non-lymphoblastic leukaemia; (2) effective anti-leukaemic therapy results in resolution of some or all of the increased marrow reticulin and is not contraindicated, even in patients with a marked increase in marrow reticulin; and (3) reappearance of an increase in marrow reticulin may be a sign of relapse of the leukaemia.
