Patients with rheumatoid arthritis (RA) and a history of cancer had a similar risk of cancer recurrence regardless of whether or not they received anti-TNF therapy in a Swedish population-based cohort study. Of the 467 patients with RA who started anti-TNF therapy a mean of 7.9 years after cancer diagnosis, 9% had cancer recurrence (mean follow-up 5.3 years) compared with 7.2% of matched patients with RA and a history of cancer who did not receive any form of biologic therapy (n = 2,164; mean follow-up 4.3 years). This difference was not statistically significant (HR 1.06, 95% CI 0.73–1.54).
