Patients with the most acute type of thrombosis in the leg – known as an arterial thrombosis – risk developing diseases that are far worse than the blood clot itself. The risk of developing cancer during the first six months after the blood clot is three times greater than normal.
This is shown by a register-based study that medical doctor and PhD Jens Sundbøll has recently published in the journal Circulation. Jens Sundbøll is employed at the Department of Clinical Epidemiology, which is part of the Department of Clinical Medicine at Aarhus University and Aarhus University Hospital.
“It is especially, but not only, the smoking-related forms of cancer that show up after the arterial thrombosis. The risk is highest for lung and pancreatic cancer, both of which are related to smoking. However, other forms of cancer such as colon cancer and leukaemia are also overrepresented,” says Jens Sundbøll about the research results.
In the study, Jens Sundbøll observes that the cancer risk is continuously increased but decreases in strength over time. After the first six months with 3-fold increased risk compared with a control group without blood clots, it falls during the next six months to ‘only’ a forty
