Additional information
Study population:Patients were selected from the Netherlands Cancer Registry (NCR), a nationwide population-based registry, which records all newly diagnosed tumours since 1989. Women diagnosed with primary invasive breast cancer between 2003 and 2006 without distant metastasis, previous, or synchronous tumours (diagnosed within 3 months after the first tumour, treated with curative intent and without neo-adjuvant systemic treatment were selected from the registry (N = 37,230).
Model development:
Variables were selected based on literature and availability of the data. Patient, tumour and treatment characteristics were assessed for their influence on recurrence risk using multivariable binary logistic regression analysis. Firstly, a prediction model for the 5-year LRR risk was developed. Secondly, risks were determined per year conditional on not being diagnosed with recurrence in the previous year(s).

Conditional information
Result interpretation
Beoogde toepassing INFLUENCE predictiemodel:
Dit model kan worden ingezet als instrument om borstkanker patiënten met een hoog risico op een locoregionaal recidief te identificeren. Op basis hiervan kan een inschatting worden gemaakt ten aanzien van de gewenste intensitieit van follow-up.
Model prestaties:
Het oppervlak onder de ROC-curve bleek bij externe validatie 0.70 te bedragen. De discriminatie van het model wordt daarmee adequaat geacht.
