Abstract
- To estimate the incidence and analyze any cancer‐associated factors in patients with systemic lupus erythematosus (SLE), differentiating between hormone‐sensitive (HS) and non‐HScancers. This was a retrospective multicenter study of a patient cohort from the Systemic Lupus Erythematosus Registry of the Spanish Society of Rheumatology. Included were the first cancer post‐SLEdiagnosis, clinical and sociodemographic information, cumulative damage, severity, comorbidities, treatments, and refractoriness. Cancers were classified as HS(prostate, breast, endometrium, and ovarian) and non‐HS(the remainder). The standardized incidence ratio (SIR) was calculated and logistic regression models were built. A total of 3,539 patients (90.4% women) were included, 154 of whom had cancer (91% female), and 44 had HScancer (100% female). The cancer SIR was 1.37 (95% confidence interval [95% CI] 1.15–1.59), with higher values in women age <65 years (SIR 2.38 [95% CI1.84–2.91]). The SIR in women with HSversus non‐HScancer was 1.02 (95% CI0.13–1.91) and 1.93 (95% CI0.98–2.89). In HSversus non‐HScancers, SLEdiagnostic age (odds ratio [OR] 1.04 [P= 0.002] versus 1.04 [P= 0.019]), and period of disease evolution (OR1.01 [P< 0.001] versus 1.00 [P= 0.029]) were associated with cancer. The Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (OR1.27 [P= 0.022]) and angiotensin‐converting enzyme (ACE) inhibitor prescriptions (OR2.87 [P= 0.048]) were associated with non‐HScancers. Cancer incidence in patients with SLEwas higher than in the Spanish population, particularly among young women. This increase might be due to non‐HScancers, which would be associated with SLEinvolving greater cumulative damage where more ACEinhibitors are prescribed.
