The Gompertz equation accurately models tumor growth, aligning with biological assumptions. Other models like logistic and Bertalanffy show deviations from this expected tumor growth pattern.

Area of Science:

Mathematical Biology
Oncology
Biophysics

Background:

Tumor growth modeling is crucial for understanding cancer progression.
Existing models like the logistic and Bertalanffy equations have limitations in accurately describing tumor kinetics.
Experimental verification of theoretical tumor growth models has been challenging.

Purpose of the Study:

To microscopically analyze tumor growth using biological assumptions.
To confirm the Gompertz equation as the definitive model for tumor growth.
To evaluate the deviations of logistic and Bertalanffy models from the expected Gompertz model.

Main Methods:

Microscopic analysis based on biological assumptions of logistic and Bertalanffy models.
Comparative analysis of Gompertz, logistic, and Bertalanffy equations for tumor growth.

Theoretical validation of the Gompertz equation's predictive power.

Main Results:

The Gompertz equation is confirmed as the expectational model for tumor growth.
The logistic and Bertalanffy equations are identified as deviated models on either side of the Gompertz equation.
The logistic model demonstrates significant bias, limiting its utility for accurate tumor growth prediction.

Conclusions:

The Gompertz equation provides a robust and theoretically sound framework for modeling tumor growth.
Understanding model deviations is key to selecting appropriate kinetic models in oncology.
This study offers a validated theoretical basis for Gompertzian tumor growth dynamics.
