The Validity of a New Procedure-Based Definition of Cancer Status in Patients with Breast-, Lung- and Colorectal Cancer in the Danish National Patient Registry.

Background/aim: The Danish National Patient Registry (DNPR) provides unique epidemiological insight, but often lacks granular data. We propose a procedure-based definition of cancer status in patients with breast-, lung- and colorectal cancer, which can be applied to administrative health databases. New definitions of cancer status are needed as mortality and morbidity are closely linked to cancer status, yet most studies only use duration since cancer diagnosis as a severity marker.

In this case report, a woman of 55 years suddenly developed foot pain and swelling 13 years after treatment for breast cancer. X-ray was found to be normal, and the symptoms were in three months interpreted as ligamentous sprains. Due to persistent pain and functional impairment together with a renewed X-ray suspicious for malignancy, an MRI scan was performed and signs of malignancy were confirmed.
