Summary
This study developed a mathematical model for gastric cancer screening. The model shows satisfactory validity for assessing individual and population gastric cancer risks.
Area of Science:
- Epidemiology
- Biostatistics
- Mathematical Modeling
Background:
- Gastric cancer poses a significant public health challenge.
- Effective screening methods are crucial for early detection and improved outcomes.
- Existing screening approaches may benefit from enhanced quantitative risk assessment tools.
Purpose of the Study:
- To develop a novel mathematical model for gastric cancer screening.
- To evaluate the model's performance in mass screening scenarios.
- To assess the model's utility in determining individual and population-level gastric cancer risk.
Main Methods:
- A case-control study involving patients and healthy individuals was conducted.
- Risk and protective factors for gastric cancer were identified and statistically analyzed.
- A quantitative assessment model using probability and fuzzy mathematics principles was established, calculating an attribute degree (AD).
Main Results:
- The model was validated using data from 63 gastric cancer patients and 693 controls.
- Optimized thresholds for sensitivity (69%) and specificity (63%) were determined.
- Statistical analysis confirmed the reliability of the model's calculations.
Conclusions:
- The developed mathematical model demonstrates satisfactory validity for gastric cancer screening.
- The model is convenient, feasible, and economical for risk assessment.
- It provides a valuable tool for determining both individual and population risks of gastric cancer.
