Abstract
Psoriasis, a chronic immune-mediated skin disorder impacting millions globally, is increasingly recognized for its links to various disease processes. As our understanding of immune dysregulation in psoriasis progresses, acknowledging the pivotal role of dysregulated T-cells in the pathogenic development of the persistent inflammatory state becomes crucial. This immune dysregulation and the resulting prevalent inflammatory state have raised concerns about psoriasis potentially serving as a significant comorbidity in cancer development among patients. To contribute to this discussion, we conducted a global retrospective cohort study with propensity score matching (PSM) using the TriNetX Analytics platform. The study aimed to investigate whether patients diagnosed with psoriasis face an elevated risk in the development of cutaneous malignancies, encompassing both melanoma and non-melanoma skin cancers. Our findings confirmed a noteworthy concern, revealing a significantly increased risk of developing cutaneous neoplasms in individuals with psoriasis. In conclusion, our study underscores the importance of heightened awareness and the necessity for routine skin cancer screenings in this unique patient population. The observed association between psoriasis and an increased risk of cutaneous neoplasms highlights the need for proactive medical interventions and emphasizes the potential impact of psoriasis as a comorbidity in the context of cancer development.
