Summary
Needle aspiration with cell blocks offers a reliable method for grading hepatocellular carcinoma (HCC) cellular dysplasia, comparable to traditional liver biopsy. This technique aids in studying HCC progression and treatment response in patients.
Area of Science:
- Hepatobiliary pathology
- Oncology
- Cytopathology
Background:
- Hepatocellular carcinoma (HCC) diagnosis relies on accurate cellular interpretation.
- Needle aspiration with cell blocks is an alternative method for obtaining tissue samples.
Purpose of the Study:
- To evaluate the utility of needle aspiration with cell blocks for interpreting hepatocellular carcinoma cellular dysplasia.
- To compare the diagnostic accuracy of cell blocks with conventional liver biopsy.
Main Methods:
- 58 patients with histologically confirmed HCC were included.
- Cellular dysplasia was graded using Edmondson-Steiner criteria for specimens from aspiration with cell blocks and liver biopsy.
- Tumor size was correlated with cellular differentiation.
Main Results:
- For small HCCs (<3.0 cm), aspiration with cell blocks showed similar grading distribution to liver biopsy.
- Larger tumors (>6.1 cm) exhibited a higher rate of poorly differentiated cells (Gr-III), indicating poorer differentiation with increasing tumor size.
- Histologic false negatives in cell blocks were more frequent in large HCCs with necrosis.
Conclusions:
- Cellular grading of HCC using aspiration with cell blocks is comparable to conventional liver biopsy.
- This method provides a valuable alternative for studying HCC cellular dysplasia and monitoring treatment response in vivo.
