Article Abstract

Objective: To investigate the expression of different histone deacetylases and their association with disease characteristics and survival outcomes in uterine leiomyosarcoma patients.

Methods: The immunohistochemical expression of different histone deacetylases and p53 by tissue microarray and histological subtypes were assessed in tumor tissue samples of 42 eligible patients.

Results: Histone deacetylases 1-4, 6 and 8 showed prevalent and strong (3+) expression (88.1, 90.5, 95.2, 92.9, 83.3 and 100%, respectively). Histone deacetylases 5, 7 and 9 showed infrequent strong expression (33.3, 50 and 38.1%, respectively). There were trends of higher disease-free survival rates according to the combination of weaker expression of histone deacetylase 5, 7 or 9 with positive p53 expression or with non-epithelial subtype. The patients with triple-positive favorable prognostic factors (any of weaker histone deacetylase 5, 7 and 9 expression, p53 positive, and non-epithelioid subtype) had the better survival outcomes while the patients with other combinations had the worse survival outcomes. In multivariate analysis, histone deacetylase 5 in combination with epithelioid subtype was an independent predictor for disease-free survival.

Conclusions: Expression of histone deacetylase 5, 7 and 9 is a potential prognostic marker in uterine leiomyosarcoma when combined with pathologically relevant prognostic factors (p53 and histological subtype). This prevalent and strong histone deacetylase expression warrants further study in well-designed investigations of histone deacetylases as therapeutic targets in uterine leiomyosarcoma.
