Abstract
BACKGROUND
Immune checkpoint inhibitors (ICIs) have transformed cancer treatment by targeting immune checkpoints such as PD-1, PDL-1, and CTLA-4, but concerns about severe immune-related adverse events persist. The scarcity of literature on dermatologic implications, especially severe reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), highlights the urgent need for investigation.
OBJECTIVE
Our systematic review aims to address the gap in relevant literature by extensively examining the epidemiologic risk factors and management of SJS/TEN-like illnesses in ICI-treated patients to provide insights for risk assessment and clinical care.
METHODS
We identified 158 case reports that detailed the incidence of SJS/TEN in patients being treated with ICIs, examining demographic patterns, type of malignancy, clinical characteristics, and treatments linked to onset. We assessed mortality rates, risk elements, and the effectiveness of interventions to help guide clinical care.
RESULTS
Analysis of 158 case reports revealed that SJS/TEN in ICI users is typically seen on average at the age of 63 and is more common in males. PD1 inhibitors such as nivolumab and pembrolizumab are often associated with various mucocutaneous patterns and significant risks with ICI use, especially TEN, which is linked to high morbidity and mortality rates.
LIMITATIONS
Our study notes limitations due to the inclusion of case reports or case series, such as potential publication and reporting biases, leading to skewed findings. Additionally, because of the heterogeneous reporting standards, the retrospective nature limits phenotypic precision, control for confounding variables, and data completeness.
CONCLUSION
Our study provides valuable insights into the epidemiology, clinical features, management strategies, and outcomes of ICI-induced SJS/TEN, underscoring the importance of vigilant monitoring and personalized risk assessment in oncology practice. Continued research efforts are essential to optimize patient outcomes and enhance the safety profile of ICIs in cancer therapy.
