[Registration of primary ovarian cancer in Denmark]

The purpose of this status article was to summarise the registration of ovarian cancer in Denmark up to 2007. In Denmark ovarian cancer is registered in four different registers/databases: The Danish Cancer Registry (CR), The Pathology Data Bank (PDB), The National Registry of Patients (LPR) and The Danish Gynaecology Cancer Database (DGCD). All four registers are obligatory, but none are 100% complete. In the future a faithful electronic registration by an electronic patient record will probably complete the variable profit ratio and data completeness.
