Of 976 patients assigned to treatment, 240 (24.6%) had primary melanoma of the head or neck, 321 (32.9%) the trunk, and 415 (42.5%) the extremities. Median follow-up was 26.9 months (range, 4.6-39.2). RFS and DMFS results by primary tumor location are presented in the table. Of 224 patients with disease recurrence (pembrolizumab, 91 [18.7%]; placebo, 133 [27.2%]), distant recurrence was the most common in patients with melanoma of the head or neck (pembrolizumab, 17 [3.5%]; placebo, 21 [4.3%]) and trunk (pembrolizumab, 18 [3.7%]; placebo, 27 [5.5%]), while locoregional recurrence was most common in patients with melanoma of the extremities (pembrolizumab, 24 [4.9%]; placebo, 22 [4.5%]). Lung was the most common site of first distant metastasis irrespective of primary site: head or neck (pembrolizumab, 8 [1.6%]; placebo, 17 [3.5%]), trunk (pembrolizumab, 11 [2.3%]; placebo, 19 [3.9%]), and extremities (pembrolizumab, 5 [1.0%]; placebo, 20 [4.1%]).
Conclusions: Consistent RFS and DMFS benefit was observed in patients with primary melanoma of the head or neck, trunk, and extremities, supporting the use of adjuvant pembrolizumab regardless of primary tumor location.
