The aim of this study was to evaluate the safety of 5-ALA in brain tumor patients with elevated preoperative liver enzymes by investigating the incidence, severity, and duration of PILE. This retrospective study was conducted in patients with a brain tumor who received 5-ALA preoperatively and had a preoperative increase in liver enzymes. Laboratory data on serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and total bilirubin (TB) levels were collected preoperatively and through postoperative day (POD) 30. The incidence and severity of PILE was evaluated based on the Common Terminology Criteria for Adverse Events. Among 134 patients, 61 (45.5%) developed 97 episodes (grade 1/2/3: 80/10/7) of PILE. Postoperative increases in ALT, AST, ALP, and TB were observed in 41 (30.6%), 33 (24.6%), 6 (4.5%), and 17 (12.7%) patients respectively. Five (3.7%) and two (1.5%) patients showed grade 3 increases in ALT and AST respectively. The maximum liver enzyme levels shown in 97 episodes resolved to preoperative baseline or normal (n = 70), grade 1 (n = 24), and gra...
