Monosomy 7 in Two Adult Patients with Acute Myeloblastic Leukaemia

Abstract
Two patients with acute myeloblastic leujaemia were found to have a population of bone marrow cells with C-group monosomy. Using the Quinacrine Mustard fluorescence technique the lacking chromosome was in both patients identified as a number 7. Both patients entered a complete remission. Monosomy 7 may indicate a separate entity of acute myeloblastic leukaemia associated with a comparatively favourable prognosis.
