    Abstract:
    OBJECTIVE: DNA ICM allows measurement of nuclear DNA content and genotypical grading of malignancy. The aim of this study was to prove the prognostic value of DNA parameter in comparison to established prognostic factors for DFS and OS. PATIENTS AND METHODS: Cytological imprints of 177 unselected primary NNBC patients were subjected to ICM. ICM parameter 2cDI, 5cEE, 9cEE, DNA mean value, proliferation fraction (SG2M) and ploidy were investigated together with established parameter like pT-stages, histology, grading, hormone receptor status and patient age regarding DFS and OS. Univariate and multivariate analysis were performed. RESULTS: Univariate analysis revealed that except ploidy all ICM parameter and pT-stages, histology as well as grading were significant prognostic factors for DFS. However, only 2cDI and pT-stages were proved independent prognostic factors in multivariate analysis. Regarding OS 9cEE, histology and pT-stages were significant factors in univariate analysis. However, only 9cEE and pT-stages were found to be independent prognostic factors in multivariate analysis. CONCLUSIONS: DNA - ICM parameter 2cDI and 9cEE together with pT-stages were proved independent prognostic factors in NNBC patients.
