ABSTRACT
Introduction
There is a complex interplay between psoriasis and cancer, with therapeutic implications. Patients with psoriasis have an increased risk of developing several types of cancer, and safety concerns have arisen regarding biologic therapies and cancer. On the other hand, biologics can provide adequate control of psoriasis that appears or worsens as an immune-related adverse event following immune enhancing checkpoint inhibitor therapy for cancer, thus allowing prosecution of oncologic treatment without impairing its efficacy.
Patients and methods
We performed a retrospective observational study of patients with moderate-to-severe psoriasis under biological treatment and cancer who were treated at our Department between January 2009 and June 2022.
Results
We included 31 adult patients with psoriasis and cancer; in 16 the diagnosis of cancer preceded the inception of biological treatment, and 9 of those patients were in remission. Most malignancies arose in the genitourinary system, followed by breast, hematologic, colorectal, thyroid, and others. Anti-IL23p19 biologics were most frequently used (36%), followed by anti-TNF (32%), anti-IL-17 (16%) and anti-IL-12/23 (16%) agents. All patients showed improvement of psoriasis after biologic initiation.
Conclusions
Biologic treatment for moderate-severe psoriasis should be considered in oncologic patients since it is not formally contraindicated and is safe. Moreover, the efficacy and safety profile of IL-23 and IL-17 inhibitors may be advantageous for those patients.
