Nuclear P27 (gene) expression in benign, borderline (LMP) and invasive tumors of the ovary and its association with prognosis: A GOG group study



Abstract

Objective

Nuclear p27 expression was examined in non-invasive and invasive ovarian tumors from a cross-sectional study, and clinical relevance of p27 was evaluated in the primary tumors from women participating in two randomized phase III treatment trials.

Methods

An immunohistochemistry assay was used to detect p27 in formalin-fixed paraffin-embedded ovarian tumors from 3 distinct sources.

Research Highlights

► Low p27 expression is associated with malignant transformation of the ovary.
► A cyclin E to p27 ratio > 1.0 may be associated with shorter survival.
Study required confirming increased recurrences with low p27 in early stage patients.
