Using the Korean National Health Insurance Service database, the relevance between psoriasis and head and neck cancer risks was investigated in a cross-sectional study of 3,869,264 individuals over 20 years of age, who received general health examination in 2009 and were followed until 2020. Head and neck cancer incidence rates were compared between individuals with and without psoriasis, and contributing factors were analysed. The head and neck cancer risk was significantly increased in the psoriasis group compared with the non-psoriasis group (hazard ratio [HR] 1.36; 95% confidence interval [CI] 1.07–1.74; p = 0.01) after adjusting for age, sex, body mass index, income, smoking, alcohol, exercise, diabetes mellitus, hypertension and dyslipidaemia. The risk was especially elevated for nasopharyngeal (HR 2.04; 95% CI 1.12–3.70; p = 0.02) and salivary gland cancer (HR 1.96; 95% CI 1.08–3.56; p = 0.03) . Alcohol consumption significantly influenced the risk, particularly for oropharyngeal and oral cavity cancer. Our study provides insights into the potential risks of head and neck cancer in patients with psoriasis, which could aid in refining patient management strategies.  \nKey words: psoriasis; head and neck cancer; nasopharyngeal cancer; salivary gland cancer.  \nSubmitted Aug 26, 2023.

Utilizing a dataset from the Korean National Health Insurance Service, our research revealed an increased risk of developing head and neck cancer in patients with psoriasis compared to those without psoriasis, while the risk was especially elevated for nasopharyngeal and salivary gland cancers. These findings provide insight into the potential risks of head and neck cancer in patients with psoriasis, which could be beneficial for refining patient management strategies.  \npredispositions, inflammatory pathogenesis and common risk factors (3, 4) .  \nRecent research has also suggested a potential association between psoriasis and an elevated risk of developing certain types of cancers, with chronic inflammation often cited as a potential contributing factor (5).
