To maximize both the life expectancy and quality of life of patients with operable breast cancer, it is important to predict adjuvant treatment outcome and likelihood of progression before treatment. A machine-learning based method is used to develop a cross-validated model to predict (1) the outcome of adjuvant treatment, particularly endocrine treatment outcome, and (2) likelihood of cancer progression before treatment. The model includes standard clinicopathological features, as well as molecular markers collected using standard immunohistochemistry and fluorescence in situ hybridization. The model significantly outperforms the St. Gallen Consensus guidelines and the Nottingham Prognostic Index, thus providing a clinically useful and cost-effective prognostic for breast cancer patients. |
