The Spectrum of Cutaneous Toxicities Related to Novel Genitourinary Cancer Therapies - Beyond the Abstract

The field of genitourinary cancer (GUC) therapy has seen significant advancements with treatments like immune checkpoint inhibitors (ICIs), antiangiogenic therapies, and novel agents such as enfortumab vedotin (EV) and erdafitinib. These therapies have revolutionized outcomes for cancers like renal cell carcinoma (RCC), urothelial carcinoma (UC), and prostate cancer (PC). However, they also bring a range of dermatologic adverse events (AEs) that may impact patient quality of life and treatment adherence.



The review highlights common cutaneous AEs such as maculopapular rash, pruritus, and alopecia, as well as more severe reactions like Stevens-Johnson syndrome linked to ICIs. Specific therapies have unique dermatologic manifestations—hand-foot skin reactions with antiangiogenic drugs and onycholysis with erdafitinib. Understanding these AEs' pathophysiology is crucial for effective management.

Risk factors for cutaneous AEs include age, immune status, BMI, and gender. Early recognition and a multidisciplinary approach involving oncologists, dermatologists, and pharmacists are essential for managing these toxicities, preventing dose reductions, or discontinuing vital therapies.

Interestingly, some studies indicate that cutaneous AEs might correlate with better oncology outcomes, suggesting an active immune response linked to improved progression-free survival and overall survival. This underscores the need for further research to understand this association fully.

This review calls for integrating dermatologic care into GUC treatment strategies. It serves as a vital resource for clinicians, highlighting the importance of collaborative management to enhance patient care and treatment efficacy. The insights provided bridge the gap between oncologic advancements and multidisciplinary support, offering a comprehensive understanding of the spectrum of cutaneous toxicities and their management.
