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.

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
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,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
