The PCORnet tumor table contains data from hospital tumor registries that are formatted according to standards developed by the North American Association of Certified Cancer Registrars (NAACCR). All hospitals that are accredited by the American College of Surgeons Commission on Cancer employ trained registrars to abstract medical record data according to these specifications. Researchers can use this resource transform their own tumor registries.
Access the GPC Tumor Table Transformation and Linkage
Structured fields for demographic, clinical, and treatment observations are included, and the data are considered to be high quality. GPC tumor table documentation includes specifications for data formats, quality checks, and relationships with other CDM tables. This standardization allows linkages between NAACCR data and the other CDM tables. It also allows queries of the NAACCR data to be quickly deployed across the network.
GPC sites have already transformed their hospital tumor registry data into the PCORnet TUMOR table format. Table specifications can be found here. A sample ETL code and workflow are attached for references.
To assess the quality and quantity of tumor registry data found in the TUMOR table at GPC sites, a quality control script was created to be run against the newly created TUMOR tables. QC reports are being used for quality evaluation.
