J. Randall Patrinely Jr., from Vanderbilt College in Nashville, Tennessee, and associates evaluated the occurrence and spectrum of persistent immune-related unfavorable occasions (irAEs) amongst 387 sufferers (median age, 63 years; 60.7 p.c male) with level III to IV melanomas handled with anti-PD-1 treatment at 8 in the USA and Australia (2015 to 2020).
