| الوصف: | Background Combination immune checkpoint blockade targeting programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) leads to high response rates and improved survival in patients with advanced cutaneous melanoma (CM). Less is known about the efficacy of this combination in acral lentiginous melanoma (ALM). Objectives To determine the efficacy of combination immune checkpoint blockade targeting PD-1 and CTLA-4 in a diverse, real-world population of patients with ALM. Methods This multi-institutional retrospective study analysed patients with histologically confirmed ALM treated with a combination of PD-1 and CTLA-4 inhibitors between 2010 and 2022. The primary objective of the study was the objective response rate (ORR) as per the RECIST criteria. The secondary objectives were progression-free survival (PFS) and overall survival (OS). Results In total, 109 patients with advanced ALM treated with combined PD-1 and CTLA-4 blockade in any line of treatment were included. The majority of patients had stage IV disease (n = 81; 74.3%). The ORR for the entire cohort was 18.3% [95% confidence interval (CI) 11.6–26.9], with 9 (8.3%) complete and 11 (10.1%) partial responses. A further 22 patients (20.2%) had stable disease, and the disease control rate was 38.5%. Median PFS was 4.2 months (95% CI 3.25–5.62), while median OS was 17 months (95% CI 12.4–23.1). Ninety-five patients (87.2%) had a treatment-related adverse event, with 40.4% (n = 44/109) experiencing at least one grade 3 or 4 toxicity. Elevated lactate dehydrogenase (P = 0.04), ≥ 2 lines of prior treatment (P = 0.03) and Asian ethnicity (P = 0.04) were associated with worse OS, while Hispanic/Latino ethnicity was associated with better OS (P = 0.02). Conclusions Combination PD-1 and CTLA-4 blockade is less effective for ALM than for CM, despite similar toxicity. In particular, Asian patients appear to derive less benefit from this regimen. Novel treatment approaches are needed for this rare melanoma subtype. |
