Methods We calculated the pre‐treatment AST/ALT ratio in 670 patients with HNSCC treated with radiotherapy (n = 309, 46.1%) or chemoradiotherapy (n = 361, 53.9%). Results Five‐year local recurrence‐free survival for patients with a low AST/ALT ratio value (n = 529, 79.0%) was 75.0% (95% CI: 71.1–78.9), and for patients with a high value (n = 141, 21.0%) it was 53.4% (CI 95: 44.4–62.4) (p = 0.0001). In a multivariable analysis, patients with a high ratio had nearly twice the risk of having a local tumor recurrence (HR 1.97, 95% CI 1.42–2.75, p = 0.0001). Conclusion The AST/ALT ratio was independently associated with the risk of local recurrence in patients with HNSCC treated with radiotherapy or chemoradiotherapy. View on the web Inoreader.
