Critical need for guidance
These guidelines meet a growing need to help practicing clinicians identify and best manage immune-related adverse events, according to Bryan J. Schneider, MD, of the University of Michigan Comprehensive Cancer Center, and vice chair of the NCCN Panel on Management of Immunotherapy-Related Toxicities.
“The mechanism of action of these anticancer therapies is so much different from anything that we’re used to,” Dr. Schneider said in an interview.“We’re experienced with chemotherapy, and we are very comfortable with the side effects,” he said. “The immunotherapy story is just an entirely different world because, as I tell patients, the therapies aren’t directly damaging cancer cells like chemotherapy. Instead, they are helping the immune system to identify the cancer cells as abnormal and mount an assault. Proteins on cancer cells may suppress the immune response and these therapies effectively ‘release these brakes’ so the immune system can attack.”
Rheumatologists and those with particular expertise in rheumatologic side effects participated in the development of the ASCO and NCCN guidelines. They include Maria E. Suarez-Almazor, MD, PhD, chief of rheumatology and clinical immunology at the University of Texas MD Anderson Cancer Center, Houston, who served on the ASCO expert panel; Jarushka Naidoo, MBBCh, from the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, provided expertise in the rheumatologic side effects that were considered by the NCCN panel, according to Dr. Schneider.
Rheumatologist input also informed another set of recommendations on immune checkpoint inhibitor toxicities published several months before the ASCO and NCCN guidelines. The working group for the September 2017 guidelines from the Society for Immunotherapy of Cancer (doi: 10.1186/s40425-017-0300-z) included Dr. Suarez-Almazor, as well as Clifton O. Bingham III, MD, director of the Johns Hopkins Arthritis Center.
