Immune checkpoint inhibitors, which strengthen the immune response against tumor cells, have become standard of care for many patients with advanced cancers; however, the medications can often cause side effects, most commonly affecting the skin. A new study led by researchers at Massachusetts General Hospital (MGH) and published in JAMA Dermatology indicates that these side effects may actually be an indicator that the medications are working.
For the study, investigators accessed the TriNetX Diamond network, a database of health records and claims data from more than 200 million U.S. and European patients. The team compared information for 14,016 patients with advanced cancer who were treated with immune checkpoint inhibitors: 7,008 who developed skin-related side effects and 7,008 who did not.
