Vigilance required
Checkpoint inhibitors have been approved by the Food and Drug Administration to treat a variety of cancers, including melanoma, lung cancer, and Hodgkin lymphoma, as well as lung, liver, kidney, and bladder cancers.
Clinicians managing patients on checkpoint inhibitors should always be vigilant because immune-related adverse event symptoms can be subtle, according to Julie Brahmer, MD, of The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore.
“Everyone has to work as a team, which includes being educated on possible side effects to immunotherapy prior to prescribing it,” said Dr. Brahmer, chair of the ASCO panel and vice chair of the NCCN panel that developed the guidelines.
The guidelines were published Feb. 14 in two documents that are similar in content, but different in format. The ASCO guideline was published in the Journal of Clinical Oncology (doi: 10.1200/JCO.2017.77.6385) and the NCCN Clinical Practice Guidelines in Oncology were posted on the NCCN website.
While the first edition of the guidelines focuses specifically on immune checkpoint inhibitors, an update anticipated for 2019 will include guidance on chimeric antigen receptor (CAR) T-cell therapy, which is associated with several important side effects, notably cytokine release syndrome.
