Evaluation of malignancy risk in patients with SSc by autoantibody profile: a systematic review with meta-analysis.
Review in Rheumatology advances in practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Increased risk of cancer has been reported in SSc patients; however, the magnitude of this risk seems to vary with SSc-specific autoantibody profile. We aimed to review cancer risk in SSc patients by autoantibody subtypes. Methods: We systematically reviewed literature related to cancer in SSc patients from January 1980 to December 2023 using PubMed, Embase, Scopus, and Cochrane Library. We performed a meta-analysis comparing cancer risk in SSc patients with ACA, anti-RNAP III antibody, and anti-Scl70 antibody. The search was conducted on 1 December 2023 and updated on 30 December 2023. Eligible studies were required to (1) include participants ≥18 years who fulfilled the 2013 ACR/EULAR, 1980 ACR modified, or LeRoy and Medsger classification criteria, (2) report cancer incidence with SSc-specific autoantibody, and (3) analyse the relationship between SSc-specific autoantibodies and cancer. Results: Twenty-two eligible studies were included and underwent meta-analysis. Anti-RNAP III positivity was associated with a significantly increased cancer risk in SSc patients (pooled relative risk (RR) 1.48; 95% CI 1.16-1.80), compared with anti-RNAP III-negative patients. While the presence of ACA was associated with a lower cancer risk (pooled RR 0.78; 95% CI 0.60-0.96) and may serve as an indicator for solely SSc, specifically limited systemic scleroderma. Conclusion: Our meta-analysis showed that anti-RNAP III-positive SSc patients had a 48% higher risk of developing cancer compared with anti-RNAP III-negative SSc patients. Therefore, physicians should be aware of this elevated risk. Rigorous screening for malignancy by age-appropriate and relevant family history is recommended.
