Why carry out this study?
 KEYNOTE-048 showed that the programmed death receptor 1 inhibitor pembrolizumab improves survival in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC).
 We assessed whether pembrolizumab is cost-effective over cetuximab + platinum + 5-fluorouracil in Argentina, as monotherapy in patients with combined positive score (CPS) ≥1, and in combination with platinum + 5-fluorouracil in the total population.
What was learned from the study?
 Pembrolizumab monotherapy and combination therapy cost AR $170,985 (2311 USD) and AR $858,306 (11599 USD) per QALY gained, respectively, making pembrolizumab a cost-effective option in Argentina.
 The results support access to pembrolizumab for patients with R/M HNSCC in Argentina.
