Summary

Highly differentiated hepatocellular carcinoma (HCC) shows reduced cell size and increased nuclear-to-cytoplasmic ratio. These cytological changes are key for diagnosing well-differentiated HCC in liver specimens.

Area of Science:

  • Hepatobiliary pathology
  • Cytopathology
  • Oncology

Background:

  • Hepatocellular carcinoma (HCC) is a significant global health concern.
  • Accurate differentiation of HCC subtypes is crucial for prognosis and treatment.
  • Cytological atypism in well-differentiated HCC can be subtle, posing diagnostic challenges.

Purpose of the Study:

  • To quantitatively characterize the cytological features of highly differentiated hepatocellular carcinoma (HCC).
  • To compare morphometric parameters between HCC subtypes and normal/diseased liver tissues.
  • To identify key parameters for the histological diagnosis of well-differentiated HCC.

Main Methods:

  • Comparative morphometric analysis of 30 HCC cases and control liver tissues (normal, cirrhotic, atrophic).
  • Quantification of hepatocyte changes using an image analyzer.
  • Measurement of mean cell size (C), mean nuclear size (N), nucleocytoplasmic (N/C) ratio, and coefficient of variance (CV).

Main Results:

  • Normotrabecular HCCs exhibited significantly reduced mean cell size (C) compared to controls.
  • A significantly higher nucleocytoplasmic (N/C) ratio was observed in normotrabecular HCCs versus controls.
  • Coefficient of variance (CV) was notably high in pleomorphic HCC and liver cell dysplasia, indicating anisokaryosis.

Conclusions:

  • Reduced cell size (C) and increased nucleocytoplasmic (N/C) ratio are characteristic cytological features of well-differentiated HCC.
  • These quantitative changes, appearing as 'nuclear crowding,' are vital for accurate histological diagnosis.
  • Morphometric analysis provides objective criteria for differentiating HCC, aiding in clinical management.
