N2 - Background: Adjuvant anti-PD-1 therapy improves relapse free survival in stage III melanoma, but also leads to immune-related adverse events (irAEs). Older patients are of particular interest due to comorbidities and frailty, which may impact their ability to tolerate irAEs and benefit from anti-PD-1 therapy. This study aimed to explore associations between clinical parameters and the occurrence of grade = 3 irAEs and recurrence-free survival (RFS) in older patients with radically resected stage III/IV cutaneous melanoma treated with adjuvant anti-PD-1 therapy. Methods: Patients aged = 65 with resected stage III/IV cutaneous melanoma treated with adjuvant anti-PD-1 therapy between 2018 and 2022 were selected using real-world data from the nationwide Dutch Melanoma Treatment Registry (DMTR). A univariate and multivariable logistic regression was used to compare determinants of grade = 3 irAEs, and univariate and multivariable Cox-proportional hazard models were fitted to identify factors influencing RFS. Results: The study included 885 patients, with 280 aged 75 and older. The incidence of grade = 3 irAEs was 15.5 % in the 65–74 age group and 13.9 % in the = 75 age group. No significant correlation was found between age and grade = 3 irAEs. However, an increasing number of comorbidities was associated with a higher risk of grade = 3 irAEs (multivariable analyses: OR 1.83, 95 % C.I. 0.99–3.40). The 1-year RFS rate of 80.0 % of this study was comparable to those reported in previous registration trials and real-world data. Having = 3 comorbidities was significantly associated with a decrease in RFS (HR: 1.68, 95 % C.I. 1.15–2.44). Conclusion: Older patients had similar benefit of adjuvant immunotherapy compared to older subgroups in previous trials. However, patients with multiple comorbidities were at increased risk of grade = 3 irAEs and had a lower RFS. This should be considered when deciding upon adjuvant treatment.
