Reported from Sweden: Rate of Venous Thromboembolism Increased With Cancer Surgery

The rate of venous thromboembolism is increased in association with cancer surgery, according to a study published online Feb. 2 in JAMA Network Open.

Johan Björklund, M.D., Ph.D., from the Karolinska Institutet in Stockholm, and colleagues examined the one-year risk of venous thromboembolic events after major cancer surgery in a register-based retrospective observational matched cohort study. Patients who underwent major surgery for cancer of the bladder, breast, colon or rectum, gynecologic organs, kidney and upper urothelial tract, lung, prostate, or gastroesophageal tract were matched with cancer-free members of the general population in a 1:10 ratio (432,218 patients with cancer and 4,009,343 cancer-free comparators).
