Age does NOT affect the chance of getting irAE or the severity when using check point inhibitors to treat cancer. Data from #CANRIO database in #Canada #ACR 23 @ACRheum @RheumNow #1063 https://t.co/bqbiXzdAqr

Obs study, bDMARDs & malignancy TNFi w/lower risk than ABA/RTX/IL6i & numerically lower than JAKs I'm a little skeptical... KM curves diverged w/~45 days, seems implausible? Agree w/first author, possible channeling bias @RheumNow #ACR23 Abstr 1678 https://t.co/1uL3j6kTSj

Sendaydiego et al. Comparative cancer safety b/tsDMARDs. 37,026 patient database cohort study. Compared to TNFi, RTX HR 2.2 (1.5, 3.3) ABA HR 1.7 (1.3-2.4), JAKi HR 1.3 (0.9-1.9). Abstr#1678 #ACR23 @RheumNow https://t.co/bTNtaNJrln https://t.co/qQBM2F2q8N

Ritux (OR 2.2), ABA (OR 1.3), JAKi (OR 1.3) significantly increase risk of cancer vs. TNFi Cohort of 37000+ RA pts starting bio/tsDMARDs (379 incident cancers) True biologic effect or confounding by indication in a generally more comorbid population? @RheumNow #ACR23 ABST1678 https://t.co/suj6mVBEC0

2 RA cohorts w/Breast Cancer 17% TNFi within 1yr after surgery No diff in overall survival at 5 yr w/ TNFi or csDMARD Trend towards better BC specific survival w/ TNFi vs. csDMARD only Worst survival for GC>7.5mg/day Only 2 yrs follow up @RheumNow #ACR23 ABST1675 https://t.co/ekKlJ2dP5i
