Insights
CD44 protein expression is significantly elevated in pediatric hepatoblastoma (HB) tissues compared to normal liver tissues. Higher CD44 levels correlate with advanced tumor stages, suggesting its role in HB progression and prognosis.
Area of Science:
- Pediatric Oncology
- Molecular Pathology
- Biomarker Research
Background:
- Hepatoblastoma (HB) is a rare pediatric liver cancer.
- Understanding molecular markers like CD44 is crucial for diagnosis and treatment.
- CD44 is a cell surface glycoprotein implicated in cancer progression.
Purpose of the Study:
- To investigate CD44 expression in pediatric hepatoblastoma.
- To determine the clinical significance of CD44 in HB patients.
- To explore the association between CD44 and HB stage.
Main Methods:
- Immunohistochemistry was used to detect CD44 expression.
- Tissue samples included 30 hepatoblastoma cases and 10 normal liver controls.
- Statistical analysis employed the chi-square test.
Main Results:
- CD44 expression was significantly higher in hepatoblastoma tissues (66.7%) versus normal liver (P < 0.05).
- Elevated CD44 expression was observed in advanced stages (III/IV) compared to early stages (I/II) of HB (P < 0.05).
- A notable difference in CD44 expression rates was found between early and advanced HB stages.
Conclusions:
- CD44 is overexpressed in pediatric hepatoblastoma.
- CD44 expression levels correlate with tumor stage in HB.
- CD44 may serve as a prognostic biomarker for hepatoblastoma in children.
Abstract:
The aim of this study was to investigate the expression of CD44 and its clinical significance in children suffering from hepatoblastoma (HB). CD44 expression was detected with immunohistochemistry staining in 30 samples from hepatoblastoma children and 10 normal liver tissue samples from normal children. The data obtained was statistically analyzed using the chi-square test, using the SPSS (v.11.0) software. The rate of CD44 expression was significantly higher (66.7%) in hepatoblastoma tissues than in normal liver tissues (χ(2) = 4.848, P < 0.05). The rate of CD44 expression was significantly higher in children with stage III or IV hepatoblastoma (83.3%) than that in children with stage I and II hepatoblastoma (χ(2) ＝ 5.625, P < 0.05) (41.7%). Therefore, CD44 expression might play an important role in the pathogenesis, progression, and prognosis of HB in children.
