Breast Cancer Subtype Prediction Model Employing Artificial Neural Network and F-Fluorodeoxyglucose Positron Emission Tomography/ Computed Tomography.

INTRODUCTION

Although positron emission tomography/computed tomography (PET/CT) is a common tool for measuring breast cancer (BC), subtypes are not automatically classified by it. Therefore, the purpose of this research is to use an artificial neural network (ANN) to evaluate the clinical subtypes of BC based on the value of the tumor marker.

MATERIALS AND METHODS

In our nuclear medical facility, 122 BC patients (training and testing) had F-fluoro-D-glucose (F-FDG) PET/CT to identify the various subtypes of the disease. F-FDG-18 injections were administered to the patients before the scanning process. We carried out the scan according to protocol. Based on the tumor marker value, the ANN's output layer uses the Softmax function with cross-entropy loss to detect different subtypes of BC.

RESULTS

With an accuracy of 95.77%, the result illustrates the ANN model for K-fold cross-validation. The mean values of specificity and sensitivity were 0.955 and 0.958, respectively. The area under the curve on average was 0.985.

CONCLUSION

Subtypes of BC may be categorized using the suggested approach. The PET/CT may be updated to diagnose BC subtypes using the appropriate tumor maker value when the suggested model is clinically implemented.
