Incorporating Breast Cancer Recurrence Events Into Population-Based Cancer Registries Using Medical Claims: Cohort Study

Abstract: Background There is a need for automated approaches to incorporate information on cancer recurrence events into population-based cancer registries. Objective The aim of this study is to determine the accuracy of a novel data mining algorithm to extract information from linked registry and medical claims data on the occurrence and timing of second breast cancer events (SBCE). Methods We used supervised data f… Show more

“…The majority of these studies focused on identifying the recurrence status but not the timing of cancer recurrence. A few studies [ 5 , 10 12 ] addressed the issue of determining the timing of recurrence by applying a prediction-model based methodology which incorporates a list of recurrence indicator variables to assign a probability of recurrence to each patient, then set a cutoff for the probability to classify recurrence vs. non-recurrence. Ritzwoller et al [ 10 ] developed recurrence identification algorithms based on multivariable logistic regression models using data derived from several distinct but integrated health care delivery settings in the U.S., and reported 60–70% estimated dates of recurrence falling within ± 6 months of the true date of recurrence.…”

“…While a number of studies explored the development of algorithms to identify second events of cancer, 6–28 very few explored developing algorithms to establish temporality of second events in the head and neck cancer population. Previous work by Xu et al developed and validated algorithms to determine second events of OPSCC 29 .…”
