PurposeFollow-up after breast cancer treatment aims for an early detection of locoregional breast cancer recurrences (LRR) to improve the patients' outcome. By estimating individual's 5-year recurrence-risks, the Dutch INFLUENCE-nomogram can assist health professionals and patients in developing personalized risk-based follow-up pathways. The objective of this study is to validate the prediction tool on non-Dutch patients.Material and methodsData for this external validation derive from a large clinical cancer registry in southern Germany, covering a population of 1.1million. Patients with curative resection of early-stage breast cancer, diagnosed between 2000 and 2012, were included in the analysis (n=6520). For each of them, an individual LRR-risk was estimated by the INFLUENCE-nomogram. Its predictive ability was tested by comparing estimated and observed LRR-probabilities using the Hosmer-Lemeshow goodness-of-fit test and C-statistics.ResultsIn the German validation-cohort, 2.8% of the patients developed an LRR within 5years after primary surgery (n=184). While the INFLUENCE-nomogram generally underestimates the actual LRR-risk of the German patients (p
