Abstract

Background No reliable estimates are available on the incidence of brain metastasis (BM) in cancer patients. This information is valuable for planning patient care and developing measures that may prevent or decrease the likelihood of metastatic brain disease. Methods We report the first population-based analysis on BM incidence at cancer diagnosis using the Kentucky Cancer Registry (KCR) and Alberta Cancer Registry (ACR). All cancer cases with BM were identified from KCR and ACR, with subsequent focus on metastases from lung primaries; the annual number of BMs at initial presentation was derived. Comparisons were made between Kentucky and Alberta for the stage and site of organ involvement of lung cancer. Results Low incidence of BM was observed in the United States until mandatory reporting began in 2010. Both the KCR and ACR recorded the highest incidence of BM from lung cancer, with total BM cases at initial presentation occurring at 88% and 77%, respectively. For lung cancer, stage IV was the most common stage at presentation for both registries and ranged from 45.9% to 57.2%. When BM from lung was identified, the most common synchronous organ site of metastasis was osseous, occurring at 28.4%. Conclusion Our analysis from the Kentucky and Alberta cancer registries similarly demonstrated the aggressive nature of lung cancer and its propensity for BM at initial presentation. Besides widespread organ involvement, no synchronous organ site predicted BM in lung cancer. BM is a common and important clinical outcome, and use of registry data is becoming more available.
