Cancer risk in rheumatoid arthritis: anything new? There is still a question I have a hard time answering with certainty when people living with rheumatoid arthritis ask me: Is there a higher risk of cancer that comes with the disease? Or with the treatments? So many https://t.co/6rbZg5Fr2k

Should we still be worried about lymphoma developing in RA patients? Incidence has plummeted with modern therapy, although still a small risk. TNFi and other bDMARDs don’t seem to confer any real risk. So what should our approach be? Karin Hellgren #EULAR2025 @RheumNow https://t.co/9ZodpojSaz

Cancer risk in rheumatoid arthritis: anything new?

Aurelie Najm, MD, PhD

Is there a higher risk of cancer that comes with the disease? Or with the treatments? So many confounding parameters, such as disease duration, disease state, and disease activity come into play. A promising session explored comorbidities in Rheumatoid Arthritis, in particular cancer and

Clinical Pearl's for #MAS Infections are still the most common cause. Next is malignancy... Then other causes like autoimmunity.. Ask a detailed history ! Sometimes check with the family when the pt can't give history.. #EULAR2025 @RheumNow https://t.co/fepercz5Af

JAKi: expanding RMD indications—but important safety concerns to consider ⚠️ Cancer: Neutral vs MTX/placebo, ↑ risk vs TNF ⚠️ Infection: ↑ with age, disease activity & GC use—not uniformly higher with JAKi 🗣️ Patients rank infection risk as top concern @rheumnow #EULAR2025 https://t.co/RJRDWQjqNC

#OP0066 Danish registry study finds no increased risk of cancer recurrence with bDMARDs vs csDMARDs in RA patients with prior solid tumor in remission. IPTW-adjusted HR for any bDMARD: 0.92 (95% CI 0.38–2.21). 📉 TNFi, ,RTX also not associated with recurrence @RheumNow #EULAR2025

Worried about cancer risk with ts/bDMARDs in RA? Real-world data from over 4,600 patients says: don’t be. No increased risk of cancer (incl. NMSC) for JAKi, IL6i, CD20i, or CTLA4-A vs TNFi in long-term registry follow-up. Abstract#OP0065 @RheumNow #EULAR2025
