Summary
Histopathology tumor classification relies on differentiation, but this has limits. Morphogenesis, a broader concept, better predicts tumor histogenesis by examining cell nature, organization, and products.
Area of Science:
- Oncology
- Pathology
- Histopathology
Background:
- Tumor classification in histopathology traditionally uses differentiation, assessing neoplastic cell resemblance to the origin tissue.
- Analyzing histological images for differentiation presents practical diagnostic limitations.
Purpose of the Study:
- To evaluate morphogenesis as a potentially superior alternative to differentiation for predicting tumor histogenesis.
- To explore the broader conceptual framework of morphogenesis in the context of tumor diagnosis.
Main Methods:
- Comparative analysis of differentiation and morphogenesis concepts in histopathology.
- Review of established principles of tumor biology and classification.
Main Results:
- Differentiation, while useful, is constrained by reliance on histological image analysis.
- Morphogenesis, encompassing cell nature, organization, and synthetic products, offers a wider perspective.
- Morphogenesis appears to be a more effective predictor of histogenesis than differentiation.
Conclusions:
- Morphogenesis provides a more comprehensive approach to understanding tumor origins than traditional differentiation.
- Rethinking tumor classification to incorporate morphogenesis could improve diagnostic accuracy in histopathology.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
