OBJECTIVE: To evaluate the incidence and clinical predictors of gastrointestinal and hepatic adverse events following oral administration of 5-aminolevulinic acid hydrochloride (5-ALA) before transurethral resection of bladder tumors (TURBT).
METHODS: Safety data were analyzed from 145 patients enrolled in the prospective, single-arm, multicenter phase III SPP2C102 trial who received 5-ALA 4-8 h before TURBT. The incidence and severity of nausea, vomiting, and liver dysfunction, defined by elevations in aspartate aminotransferase, alanine aminotransferase, and/or gamma-glutamyltransferase, were assessed according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Potential risk factors were evaluated using univariable and multivariable logistic regression; results are reported as adjusted odds ratios (aOR) with 95% confidence intervals (CIs).
RESULTS: Nausea/vomiting occurred in 28/145 patients (19.3%), all CTCAE grade 1-2. Female sex was independently associated (aOR 3.15, 95% CI 1.17-8.47), and diastolic blood pressure ≥ 80 mmHg showed a borderline association (aOR 2.37, 95% CI 0.99-5.78). Prophylactic antiemetics yielded a numerically lower rate (21.1% vs. 9.1%; p = 0.25). Liver-enzyme elevations similarly occurred in 28/145 patients (19.3%), all CTCAE grade 1-2. Systolic blood pressure ≥ 130 mmHg remained independently associated (aOR 4.73, 95% CI 1.62-13.78), whereas associations for hypertensive comorbidity and BMI ≥ 25 kg/m2 in univariable analyses did not persist after adjustment.
CONCLUSION: 5-ALA-related nausea, vomiting, and transient liver-enzyme elevations were common but generally mild. Simple bedside variables-particularly sex and blood pressure-may guide selective antiemetic prophylaxis and closer biochemical monitoring in routine practice.
