Risk of new primary cancer, locoregional progression or metastasis associated with bDMARDs and tsDMARDs in patients with rheumatoid arthritis and prior cancer: insights from the ARCA registry.
Article in RMD open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo compare the risk of new primary cancer, locoregional progression or metastasis across different disease-modifying antirheumatic drugs (DMARDs) strategies in real-world patients with rheumatoid arthritis (RA) and prior cancer.
methodsThe ARthritis and CAncer registry is a nationwide retrospective study, including patients with RA and prior cancer. Collected variables included RA characteristics, DMARDs received, cancer type and demographics. The primary outcome was the occurrence of new primary cancer, locoregional progression or metastasis during follow-up. Adjusted Cox regression models were used to estimate HRs for cancer events. Treatment strategies involving conventional synthetic (cs)DMARDs served as the reference for comparison.
resultsAmong 728 patients with RA, 80 cases of cancer were identified over a cumulative exposure period of 11 022 years, with an overall cancer incidence rate of 7.3 (95% CI 5.8 to 9.0) per 1000 person-years. Adjusted HRs for all cancers (95% CI) compared with csDMARDs were 0.94 (0.73 to 1.21) for tumour necrosis factor inhibitors, 1.03 (0.61 to 1.74) for IL6-inhibitors, 0.81 (0.46 to 1.42) for CD20 inhibitors, 0.6 (0.26 to 1.4) for targeted synthetic DMARDs and 0.74 (0.41 to 1.34) for cytotoxic T-lymphocyte-associated protein 4-analogue. No differences in cancer risk were observed after adjusting for duration of exposure, line of advanced therapy or prior cancer status.
conclusionThis real-world data did not identify differences in the risk of new primary cancer, locoregional progression or metastasis across different DMARDs strategies in patients with RA and prior cancer.
