Prognostic value of DNA cytometry in 281 premenopausal patients with lymph node negative breast carcinoma randomized in a control trial

Abstract

Evaluation of proliferative compartment was the most important predicting factor for OS and MFS in the current series of premenopausal lymph node negative patients with breast invasive carcinoma. When working on paraffin embedded tissue, the best way of assessing it was MI count. ICM DNA analysis results were not selected in multivariate analysis. DNA analysis by FCM should be considered as an unsuitable technique when working on paraffin embedded tissue.
