Summary
Lens culinaris agglutinin A-reactive fraction of alpha-fetoprotein (AFP-L3) may predict hepatoblastoma recurrence. AFP-L3 levels decreasing post-surgery indicate a lower risk of recurrence compared to standard alpha-fetoprotein (AFP) levels.
Area of Science:
- Oncology
- Biomarkers
- Pediatric Surgery
Background:
- Alpha-fetoprotein (AFP) is a sensitive biomarker for active hepatoblastoma (HB).
- Predicting recurrence after complete resection is crucial for patient management.
Purpose of the Study:
- To evaluate if Lens culinaris agglutinin A-reactive fraction of AFP (AFP-L3) post-resection predicts HB recurrence.
- To compare AFP and AFP-L3 as early prognostic factors for HB recurrence.
Main Methods:
- Retrospective analysis of 14 hepatoblastoma patients undergoing complete resection.
- Comparison of AFP and AFP-L3 levels pre- and post-surgery between recurrence and non-recurrence groups.
Main Results:
- No significant difference in early postoperative AFP levels between groups.
- AFP-L3 fell below detection limits in 70% of the non-recurrence group by 2 months post-surgery, versus 0% in the recurrence group (P=0.03).
- AFP-L3 decline was a more sensitive indicator of non-recurrence than AFP level normalization.
Conclusions:
- AFP-L3 is a potentially earlier and more reliable predictor of hepatoblastoma recurrence than AFP.
- Monitoring AFP-L3 levels after complete resection may aid in assessing recurrence risk.
