When Your Patient with Psoriasis Is Diagnosed with Cancer

A patient doing well on an IL-17 inhibitor is diagnosed with cancer, and the oncologist wants the biologic stopped. It is a call most dermatologists have made without much to stand on: patients with cancer are excluded from psoriasis trials, so the entire evidence base is observational. A new IPC paper in JAAD Reviews takes a position anyway. Per the summary of product characteristics, active malignancy is not a contraindication to any biologic. IL-17 and IL-23p19 inhibitors are first-line, TNF inhibitors and deucravacitinib warrant caution, and cyclosporine is the one to avoid outright. The authors also warn that psoriasis severity is routinely underestimated once a patient is in oncology care: if they meet IPC’s criteria, they are a candidate for systemic therapy regardless of what else is on their problem list. “Too often, systemic psoriasis therapy is discontinued or never initiated in patients with cancer, even when the evidence supports safe and effective options,” says Paolo Gisondi, MD, IPC Councilor and lead author. The post includes the therapeutic options figure, designed as a reference for both specialties to work from, and a slide set for teaching and presentations.

IPC Generalized Pustular Psoriasis (GPP) Training Modules

Recognizing GPP in clinical practice can be a challenge, even for experienced dermatologists. IPC’s new five-part training series walks clinicians through the practical skills needed to diagnose and assess GPP with confidence: distinguishing it from plaque psoriasis and other mimicking conditions, and scoring its severity using tools such as the GPPGA and GPPASI. Each module pairs an expert-led video with a case-based exercise, and the series is built to be completed in sequence at your own pace. All five modules are free and open to everyone; watch the videos on your own or work through the assessments as you go. Score 80% or higher on each of the five assessments to earn a Certificate of Completion.

IPC Summary Slides: Psoriasis and Metabolic Health

IPC has released a set of summary slides distilling the key findings from its recent publication on psoriasis and metabolic health, published in the Journal of the American Academy of Dermatology (JAAD). The paper outlines five priorities for improving cardiometabolic risk screening and care in patients with psoriasis. Designed for sharing, the slides give clinicians and colleagues an easy way to disseminate the findings.
