Abstract

OBJECTIVE: To quantify the burden of cancer in systemic sclerosis (SSc). METHODS: Standardized incidence ratios (SIRs) and standardized mortality ratios relative to the general Australian population were derived. Cox proportional hazards regression was used to estimate survival in patients with SSc with cancer compared to patients without. Determinants of cancer were identified using logistic regression. Health care cost was quantified through cross-jurisdictional data linkage. RESULTS: This SSc cohort of 1,727 had a cancer incidence of 1.3% per year and a prevalence of 14.2%, with a SIR of 2.15 (95% confidence interval [95% CI] 1.84-2.49). The most common cancers were breast, melanoma, hema..
