Propofol-based intravenous anesthesia is associated with improved survival outcomes after major cancer surgery: a nationwide cohort study in South Korea.

Background: The optimal anesthetic technique for cancer surgery remains a controversial issue. This study aimed to examine whether propofol-based total intravenous anesthesia (TIVA) was associated with survival outcomes after major cancer surgery in South Korea and compare its effectiveness with that of inhalation anesthesia.

Methods: This nationwide population-based cohort study included adult patients who were admitted to the hospital and underwent major cancer surgery between January 1, 2016, and December 31, 2020.
