The study included 53,778 patients with AK and 152,896 controls without prior cancer diagnoses at enrollment. AK was more prevalent in males (30.7 vs 23.5% in females). AK was not associated with increased risk of overall nonskin cancers after adjusting for demographic (age, sex), clinical (body mass index, immunosuppression history), behavioral (smoking, alcohol use), and healthcare utilization factors (adjusted hazard ratio = 0.99, 95% confidence interval = 0.95–1.02). However, significant associations were observed between AK and breast (adjusted hazard ratio = 1.11, 95% confidence interval = 1.03–1.19) and prostate (adjusted hazard ratio =1.14, 95% confidence interval = 1.03–1.26) cancers. This large study reveals that AK may be a predictor of risk for subsequent cancers, notably breast and prostate cancers.
