Summary

Nucleolar size in breast cancer varies significantly by histological type. Invasive ductal carcinoma shows larger nucleolar volumes compared to invasive lobular carcinoma and mucinous adenocarcinoma, aiding in tumor characterization.

Area of Science:

  • Oncology
  • Pathology
  • Stereology

Background:

  • Histopathological typing of breast carcinomas offers good prognostic value.
  • Cell size determination is a common diagnostic parameter in malignancies.
  • Stereological methods enable unbiased estimation of nucleolar volume.

Purpose of the Study:

  • To present data on nucleolar size in breast carcinoma.
  • To investigate differences in nucleolar volume among various breast cancer histological types.

Main Methods:

  • Stereological measurements using a light microscope and eyepiece graticule.
  • Point sampling of nucleolar intercepts for volume estimation.
  • Analysis of 39 breast carcinoma patient samples stained with hematoxylin and eosin.

Main Results:

  • Nucleolar volume was significantly larger in invasive ductal carcinoma (12.34 ± 3.48 μm³) compared to invasive lobular carcinoma (5.6 ± 2.73 μm³).
  • Mucinous adenocarcinoma exhibited the smallest nucleolar volume (0.88 ± 0.42 μm³).
  • Significant differences in nucleolar volume were observed across various histological types of breast cancer.

Conclusions:

  • Nucleolar volume is a differentiating parameter among breast cancer histological subtypes.
  • Histological type significantly influences nucleolar size in breast carcinoma.
  • Nucleolar volume measurement can contribute to the histopathological characterization of breast cancer.
