An Assisted Diagnosis Model for Cancer Patients Based on Federated Learning

Abstract

Since the 20th century, cancer has been a growing threat to human health. Cancer is a malignant tumor with high clinical morbidity and mortality, and there is a high risk of recurrence after surgery. At the same time, the diagnosis of whether the cancer is in situ recurrence is crucial for further treatment of cancer patients. According to statistics, about 90% of cancer-related deaths are due to metastasis of primary tumor cells. Therefore, the study of the location of cancer recurrence and its influencing factors is of great significance for the clinical diagnosis and treatment of cancer. In this paper, we propose an assisted diagnosis model for cancer patients based on federated learning. In terms of data, the influencing factors of cancer recurrence and the special needs of data samples required by federated learning were comprehensively considered. Six first-level impact indicators were determined, and the historical case data of cancer patients were further collected. Based on the federated learning framework combined with convolutional neural network, various physical examination indicators of patients were taken as input. The recurrence time and recurrence location of patients were used as output to construct an auxiliary diagnostic model, and linear regression, support vector regression, Bayesling regression, gradient ascending tree and multilayer perceptrons neural network algorithm were used as comparison algorithms. CNN’s federated prediction model based on improved under the condition of the joint modeling and simulation on the five types of cancer data accuracy reached more than 90%, the accuracy is better than single modeling machine learning tree model and linear model and neural network, the results show that auxiliary diagnosis model based on the study of cancer patients in assisted the doctor in the diagnosis of patients, As well as effectively provide nutritional programs for patients and have application value in prolonging the life of patients, it has certain guiding significance in the field of medical cancer rehabilitation.

A Comprehensive Survey on Federated Learning in the Healthcare Area: Concept and Applications

“…A survey by Moshawrab et al [43] thoroughly examined federated learning, providing a theoretical explanation and comparing it to other technologies. Disease prediction also highlights the application of federated learning in diagnosing cancer [92], diabetes [82], and cardiovascular diseases [93].…”

A Transfer Learning Approach to Breast Cancer Classification in a Federated Learning Framework

“…Based on the FL framework combined with CNN, the paper in [35] used CNN's federated prediction model is based on improvements in general modeling and simulation conditions on five types of cancer, the accuracy of cancer data reaches more than 90%, the accuracy is better than the tree model single model machines and linear models and neural networks. However, this study still lacked comparisons with different models rather than only MLP and did not address the issue of data imbalance and treatment.…”

A Federated Learning Approach to Breast Cancer Prediction in a Collaborative Learning Framework

“…Ma et al [30] employed a hybrid approach, integrating the FL framework with Convolutional Neural Networks (CNN), in order to create a federated prediction model. This study showcased improvements in overall modeling and simulation conditions for five distinct forms of cancer.…”
