Insights
Beckwith-Wiedemann syndrome (BWS) and hemihypertrophy (HH) infants with hepatoblastoma may have high alpha-fetoprotein (AFP) levels post-surgery. Persistent high AFP in BWS can mimic tumors, requiring imaging alongside AFP monitoring for accurate diagnosis.
Area of Science:
- Pediatric Oncology
- Genetics
- Endocrinology
Background:
- Beckwith-Wiedemann syndrome (BWS) and hemihypertrophy (HH) are overgrowth disorders linked to increased cancer risk.
- Hepatoblastoma is a common childhood liver cancer, often associated with overgrowth syndromes.
Observation:
- A case report of an infant diagnosed with both BWS and HH presented with hepatoblastoma.
- The infant exhibited persistently high serum alpha-fetoprotein (AFP) levels even after successful surgical removal of the tumor.
Findings:
- The persistent elevation of AFP, despite no evidence of tumor recurrence, suggests a non-tumor-related cause.
- This phenomenon may be attributed to the inherent proliferative nature of the underlying condition in BWS.
Implications:
- Clinicians must recognize that prolonged high AFP levels in infants with BWS can mimic residual or recurrent disease.
- Treatment decisions and patient management should integrate AFP monitoring with regular radiological imaging for accurate assessment.
- This highlights the importance of a comprehensive diagnostic approach beyond single biomarker measurements in complex pediatric cases.
Abstract:
Both Beckwith-Wiedemann syndrome (BWS) and hemihypertrophy (HH) have been recognized to be overgrowth syndromes associated with an increased risk of cancer. We report an infant with hepatoblastoma associated with both BWS and HH in whom high serum alpha-fetoprotein (AFP) levels persisted even after complete tumor resection with no tumor recurrence. This phenomenon might be partly due to the nature of the proliferative disease. It is important to recognize that in some infants with BWS prolonged high serum AFP levels mimic the existence of a tumor, and that treatment should be based not only on AFP measurement, but also on repeated radiologic imaging.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
