Key clinical point: Patients with psoriatic arthritis (PsA) are at a higher risk for overall cancer compared with the general population, highlighting the importance of regular cancer screening among these patients.
Major finding: The risk for overall cancer was slightly higher among patients with PsA vs age- and sex-matched control individuals (adjusted hazard ratio [aHR] 1.20; 95% CI 1.02-1.41), with the risk being mainly driven by non-melanoma skin cancer (aHR 3.64; 95% CI 1.61-8.23), lymphoma (aHR 2.63, 95% CI 1.30-5.30), and thyroid cancer (aHR 1.83, 95% CI 1.18-2.85).
Study details: The data come from a population-based cohort study including 4688 patients with newly diagnosed PsA and 46,880 age- and sex-matched control individuals without a history of cancer and other coexisting autoimmune diseases from the general population.
