We also identified pre-to-postoperative dynamics of the AST/ALT ratio (HR: 2.18, 95% CI: 1.23–3.89) as an independent predictor of OS, as well as tumor size (HR: 2.91, 95% CI: 1.93–4.40), pT stage (HR: 2.20, 95% CI: 1.47–3.28), and age at surgery (HR: 2.03, 95% CI: 1.36–3.02), as shown in Table 3. Here, GPT is linked to neoplasm.
