Biologically interpretable shape features accurately classify renal tumors from histological images, outperforming traditional methods. These shape features also correlate with known tumor biology, aiding pathologists in diagnosis.

Area of Science:

  • Computational pathology
  • Digital image analysis
  • Oncology

Background:

  • Automatic cancer diagnosis using histological images aids therapeutic decisions.
  • Traditional systems use textural and morphological features, but lack biological interpretability.
  • Pathologist reluctance stems from the unclear biological basis of many current features.

Purpose of the Study:

  • To evaluate biologically interpretable shape-based features for renal tumor classification.
  • To compare the diagnostic performance of shape-based features against traditional models.

Main Methods:

  • Extraction of shape-based features using Fourier shape descriptors from histological images.
  • Development of a multi-class prediction model utilizing these shape features.

  • Comparison with models based on textural, morphological, and topological features.

    • Main Results:

    • The shape-based model achieved an average accuracy of 77%, surpassing traditional methods.
    • Identified key informative shapes specific to each renal tumor subtype.
    • Demonstrated correlation between diagnostic shape features and known tumor biological characteristics.

    Conclusions:

    • Shape-based analysis provides accurate classification of renal tumor subtypes.
    • This approach yields biologically meaningful discriminatory features.
    • The method is extendable to other histological datasets, supporting diagnostic and therapeutic decisions.
