The Danish National Multiple Myeloma Registry (LYFO) is a clinical quality database and part of the Hematological Common Database. LYFO contains data about patients with malignant lymphoma (lymph cancer), a disease affecting the lymph cells of the immune system (lymphocytes).

The purpose of LYFO is to register diseases and their characteristics from the time of diagnosis and to follow the course of the disease. The aim is to assure quality of diagnosis and treatment of these diseases in Denmark.

LYFO was established in 1983 as one of the first population-based lymphoma databases. The database has been national since 2000 but until 1999, it only included patients from West Denmark. All haematological departments in Denmark report to the database, with additional data from the National Patient Register (LPR), National Pathology Register and the CPR Register.

The Regional Clinical Quality Databases

Data about clinical quality are collected with the purpose of monitoring and raising the quality of patient treatment in the Danish health-care system. These data can, as well as all other public registers, be made accessible for research projects based on systematic protocols and approved according to the relevant legislations.

Applying for access to data from a regional clinical database requires a list of demands to be obtained. A project description should be attached containing a description of the project explaining the rationale, purpose, methods, budget, publication plan etc.

Furthermore, The Danish Data Protection Agency must approve the project.

Application process

  • Apply via research access (Danish: forskeradgang), an online application system
  • Submit the protocol to The Danish Clinical Registries (RKKP)
  • RKKP registers the application
  • The application is forwarded to the relevant clinical database
  • Potential dialog about adjustment to the protocol
  • Approval and extradition of data (expected 6 months after application)



The Regional clinical quality databases subject to rules for treatment of personal data, that should secure high quality of patient treatment in Denmark. These legislations include The Act on Processing of Personal Data (Danish: Persondataloven) and The Danish Act of Health (Danish: Sundhedloven).
