However, single-agent checkpoint therapies have yet to show benefit to overall survival (OS) for lower-risk stage III cancers. We evaluated the OS benefit of post-operative immunotherapy in the National Cancer Database (NCDB) .  \nPatients and methods: Patient cases were selected from the NCDB 2020 Participant Use File. Patients diagnosed with stage III cutaneous melanoma between 2016 and 2019 who underwent definitive resection for their melanoma were included. OS between those who received post-operative immunotherapy within 84 days of surgery and those who did not was analyzed by the KaplaneMeier method. Demographic and clinical characteristics between the two groups were compared via Cox proportional hazard models.  \nResults: 14 978 patients with stage III melanoma were included. Of those, 34 .9%(n ¼ 5234) received post-operative immunotherapy and 65 . 1%(n ¼ 9744) did not. Using the American Joint Committee on Cancer version 8 (AJCCv8) staging, 36-month survival was significantly higher in patients who received post-operative immunotherapy compared to no post-operative systemic therapy in those diagnosed with stage IIIB (88 .0% versus 84 .7%, P ¼ 0.011), IIIC (75 .6% versus 68 . 1%, P \u003C 0.001), or IIID (59 . 2% versus 48 .4%, P ¼ 0.002) . No significant improvement in 36-month survival was seen in patients who received post-operative immunotherapy in patients with stage IIIA disease (93 .0% versus 92 . 2%, P ¼ 0. 218) .  \nConclusions: Post-operative immunotherapy had an OS benefit in patients with AJCCv8 stage IIIB, IIIC, and IIID disease, but had no significant survival benefit for patients with stage IIIA melanomas.  \nKey words: immunotherapy, melanoma, adjuvant immunotherapy  \nINTRODUCTION  \nApproximately 9% of the 97 610 cases of cutaneous melanomas diagnosed in the United States in 2023 will have regional disease at diagnosis.1 Stage III cutaneous melanoma outcomes are heterogenous and largely dependent upon substage. In the American Joint Committee on Cancer (AJCC) version 8 staging system, stage IIIA melanoma has a high cure rate with a 93% melanoma-specific survival at 5  \n*Correspondence to: Dr Justin T.
