Title

CAN BIOMARKERS IMPROVE ABILITY OF NPI IN RISK PREDICTION? A DECISION TREE MODEL ANALYSIS

Pages

  62-74

Abstract

 Background: The Nottingham Prognostic Index (NPI) is widely-used in the UK for risk stratification of breast cancer patients. This paper aims to evaluate the ability of this index to detect patients with sufficiently low risk of recurrence that they could be spared harsh treatments, and to construct an enhanced prognostic rule that integrates biomarkers with clinical variables to achieve better risk stratification.Methods: We undertook review of published studies of outcomes in risk groups derived by applying NPI, and report estimated event-free rates extracted from papers found. Then we analysed biological and clinical variables for 401 ER+ patients, to develop a Tree-based Survival Model (TSM), for risk prediction, and estimated event-free rates by resulting risk-groups, Kaplan-Meier (K-M) curves corresponding to TSM and NPI were plotted. Results: We concluded that NPI does not distinguish low risk patients with a sufficiently high event-free rate to make it likely clinicians would decide treatments with potential harmful side effects can be avoided in that group. On the other hand, in the decision tree constructed, utilising 3 biomarkers, nodal status and tumour size, the 4 risk groups were clearly diverged in terms of event-free rates. Conclusion: There is considerable potential for improved prognostic modelling by incorporation of biological variables into risk prediction. Whilst low risk patients identified by our TSM model could potentially avoid systemic treatment, higher risk patients might require additional treatment, including chemotherapy or other adjuvant treatment options. However, the decision tree model needs to be validated in a larger clinical trial cohort.
