Key clinical point: This Mendelian randomization (MR) analysis established that there exists no causal association between psoriatic arthritis (PsA) and the genetic risk for skin cancer.
Major finding: PsA did not increase the genetic susceptibility to cutaneous squamous cell carcinoma (odds ratio [OR] 1.00; P = .214) and cutaneous melanoma (OR 1.00; P = .477). Although PsA decreased the genetic risk for basal cell carcinoma (OR 0.94; P = .016), the association disappeared when skin cancer risk factors like skin tanning, radiation-related disorders, and telomere length were considered.
Study details: Findings are from a multivariate MR analysis including 3186 patients with PsA and 240,862 control individuals without PsA.
Disclosures: This study was supported by the Natural Science Foundation of China and the Youth Science Foundation of Xiangya Hospital. The authors declared no conflicts of interest.
