Abstract

Objective: The main goal of our study was to identify the earliest and specific genetic changes which could be associated with an increased risk of neoplastic transformation in a group of patients with endometrial hyperplasia. Another goal was to characterize genetic changes associated with advanced forms of cancer. Material and methods: The study involved forty-four (44) female patients, including five (5) patients with no histopathologically confirmed hyperplastic features, twenty-six (26) patients with histopathologically confirmed endometrial hyperplasia, and thirteen (13) patients with diagnosed carcinoma of the endometrium. The study was conducted using a custom-made 4x180K microarray of BlueGnome. Results: Copy number variations (CNV) were found in the cases without endometrial hyperplasia. Such changes occur with varying frequency in the genome of healthy female population. Significant genome imbalance was identified in the twenty-six (26) (100%) patients with diagnosed hyperplasia and in eleven (11) subjects (84.6%) with diagnosed endometrial cancer. Other, not yet reported, changes localized in characteristic regions of the genome were also found.
