Case Ascertainment of Pediatric Brain Tumours: The Alberta Experience.

Estimates suggest that brain tumors are underreported in the Alberta Cancer Registry (ACR). While the reporting of malignant tumors is thought to be complete in cancer registries across Canada, the reporting of benign tumors is estimated at 33 percent of the actual number of cases expected within the country.6 There are many international studies that highlight the issues of underreporting of benign brain tumors in cancer registries.

Incidence of brain metastasis at initial presentation of lung cancer.

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).
