Histone H4 acetylation by immunohistochemistry and prognosis in relapsed acute lymphocytic leukaemia (ALL).
Histone H4 acetylation was examined by immunohistochemistry in patients with acute lymphocytic leukaemia (ALL) in first relapse. Univariate and multivariate models identified correlates of complete remission (CR) and overall survival (OS). No variables were associated with achievement of CR. In multivariate analysis, weak histone H4 acetylation [Hazard Ratio (HR) 2·20, 95% confidence interval (CI) 0·93-5·23, P=0·07], shorter interval from diagnosis to relapse (<9 vs. 9-24 vs. >24 months) (HR 1·82, 95% CI 1·20-2·75, P= 0·005), and central nervous system involvement (HR 3·43, 95% CI 1·31-8·99, P=0·01) were independent poor prognostic factors for OS. These data provide a rationale for the use of histone deacetylase inhibitors in the treatment of relapsed ALL.
