This survival advantage remained highly significant in the 60-day landmark analysis ( p = 0.004).

Furthermore, while the occurrence of severe postoperative complications (Clavien-Dindo ≥ III) was prevalent across the cohort, their inclusion in the multivariable model demonstrated a trend toward increased mortality that did not reach statistical significance (HR = 1.67, 95% CI 0.86–3.23, p = 0.130) and did not diminish the strong, independent survival benefit associated with completing the perioperative treatment sequence.
