Validation of the Singapore nomogram for outcome prediction in breast phyllodes tumours : an Australian cohort

Aim: To validate the utility of the Singapore nomogram for outcome prediction in breast phyllodes tumours. Methods: Histological parameters, surgical margin status and clinical follow-up data of 34 women diagnosed with phyllodes tumours were analysed. Biostatistics modelling was performed, and the concordance between predicted and observed survivals was calculated. Results: Women with a high nomogram score had an increased risk of developing relapse, which was predicted using the parameters defined by the Singapore nomogram. Conclusions: The Singapore nomogram is useful in predicting outcome in breast phyllodes tumours when applied to an Australian cohort of 34 women.
