title: Correlation of haematological, electron microscopic and cytogenetic findings in 20 patients with preleukaemia.
abstract: A combined haematological, ultrastructural and chromosomal study was made in 20 patients with preleukaemia. There was evidence of specific correlations between (a) Hb F levels and pancytopenia or profound anaemia, (b) chromosomal and electron microscopic findings and (c) thrombocytosis and ringed sideroblasts. The above findings might be of importance in identifying subgroups of preleukaemic patients with different prognosis.
