38 Cancers risk in RA Patients RA cohort (n=66 471) - 0.7% of Swedish population alive in 1998, identified in 3 overlapping national registersFollowed through to 2005Cancer in RA not treated with anti-TNF Relative risk of cancer[OP0013] NO INCREASE IN OVERALL RISK FOR CANCER IN RA TREATED WITH TNF-ANTAGONISTS, BUT RISKS FOR CERTAIN CANCER TYPES MAY BE ELEVATED J. Askling 1, for the ARTIS Study Group 2 1Dept of Rheumatology, Karolinska University Hospital, Stockholm, 2Sweden Background: The occurrence of cancer following treatment with TNF-antagonists is not well understood. Whereas analyses of randomized trials suggest the possibility of an early and marked increase in the occurrence of several cancer types, observational studies have typically not been able to detect any increased overall cancer risk, although excess risks of certain types of cancer have been reported. Systematic or inadvertent screening before start of TNF-antagonist treatment may have excluded individuals with incipient cancer. By contrast, the direct effects of TNF-antagonist treatment might unmask incipient malignancies. It follows that only long-term assessments of cancer risk will allow an unbiased assessment of the full cancer occurrence associated with TNF-antagonists. Objectives: To assess the cancer occurrence in RA treated with TNF-antagonists Methods: Using the Swedish Biologics Register (ARTIS), pre-existing RA-cohorts, and matched individuals from the general Swedish population, we created three cohorts of (i) all 5,401 RA-patients starting TNF-antagonist treatment 1998 until 2005, (ii) 67,094 contemporary comparator RA-patients, and (iii) a matched general population cohort of 470,311 subjects. All unique individuals were followed for vital status 1998 until 2005 through national registers, and for malignancies through linkage to the Swedish Cancer Register (the mandatory Swedish notification system for malignancies) 1998 until Through stratified (age, sex, county, calendar year) and adjusted (four co-morbidities and joint surgery) Cox-regressions, the overall and site-specific occurrence of first primary cancers following RA-treatment with TNF-antagonists was compared to that of other RA, and to that of the general population. Results: Compared to the general population comparator (23,827 cancers, 2,650,119 person-years), the cancer occurrence in the RA cohort treated with TNF-antagonists (129 cancers whereof 114 first primaries during 14,261 person-years) corresponded to a relative risk of 1.07 (95% CI ), and the cancer occurrence in the RA cohort not treated with TNF-antagonists corresponded to a relative risk of 1.09 ( ). The adjusted relative risk comparing RA patients treated vs. not treated with TNF-antagonists was 0.93 ( ), which included a transient drop in cancer risk in the TNF-antagonist treated group 1-3 years after first treatment start: RR < 1 year since first treatment start = 0.90 ( ), RR 1 to 3 years since first treatment start = 0.62 ( ), and RR 3 or more years since first treatment start = 1.06 ( ). When site-specific cancer risks were assessed, RA treated (vs. not treated) with TNF-antagonists was associated with a reduced risk of breast cancer (RR=0.48, 95% ). Non-significant increased risks were observed for colorectal (RR=1.52, 95% , n=14), for non-melanoma skin (RR=1.55, 95% , n=10), and for CNS (RR=2.25, 95% , n=5) cancers. Conclusion: The overall cancer risk in RA-patients treated with TNF-antagonists is not higher than that among biologics-naïve RA-patients, and both these risks are largely similar to that of the cancer occurrence in the general population. The increased occurrence of non-melanoma skin cancer, of CNS tumours, and of colorectal cancer, although statistically strictly not significant and based on small numbers, needs further monitoring.Askling J, et al EULAR 2007, Barcelona, #OP001338

Standard non-biologic treatments do not increase this underlying lymphoma risk.The relative risks of lymphoma were only modestly elevated up to the seventh decile of cumulative disease activity.After that, the relative risk increased dramatically (OR ninth decile 9.4 [95% confidence interval 3.1–28.0], OR tenth decile 61.6 [95% confidence interval 21.0–181.0]).Most lymphomas (48%) were of the diffuse large B cell type, but other lymphoma subtypes also displayed an association with cumulative disease activity. EBV was present in 12% of lymphomas.The data shows results from 376 patients with RA complicated by malignant lymphoma and 376 matched controls.ReferenceBaeklund E, et al.
