Lung Cancer Management: Revolutionizing Patient Outcomes Through Machine Learning and Artificial Intelligence

Sep 23, 2026

Uploaded by Terk

Lung cancer remains a leading cause of cancer-related deaths worldwide, making early detection essential for improving patient prognosis. Traditional machine learning models often struggle with limited clinical generalizability. This study develops a two-stage deep learning framework that uses transfer learning to segment lung tumor regions from CT scans and classify images as cancerous or noncancerous, addressing gaps seen in conventional approaches.

Traditional machine learning (ML) models have shown limited generalizability in clinical settings. This study proposes a deep learning-based approach using transfer learning to accurately segment lung tumor regions from CT scansand classify images as cancerous or noncancerous, aiming to overcome the limitations of conventional ML models. Methods: We developed a two-stage model utilizing a ResNet50 backbone within a U-Net architecture for lesion segmentation, followed by a multi-layer perceptron (MLP) for binary classification. The model was trained on publicly available CT scan datasets and evaluated on an independent clinical dataset from Hazrat Rasool Hospital, Iran. Training employed binary crossentropy and Dice loss functions. Data augmentation, dropout, and regularization were used to enhance model generalizability and prevent overfitting. Results: The model achieved 94% accuracy on the real-world clinical test set. Evaluation metrics, including F1 score, Matthews correlation coefficient (MCC), Cohen's kappa, and Dice index, confirmed the model's robustness and diagnostic reliability. In comparison, traditional ML models performed poorly on external test data despite high training accuracy, highlighting a significant generalization gap. Conclusion: This research presents a reliable deep learning framework for lung cancer detection that outperforms traditional ML approaches on external validation. The results demonstrate its potential for clinical deployment. Future work will focus on prospective validation, interpretability techniques, and integration into hospital workflows to support real-time decision making and regulatory compliance. | Abbreviations: AI, artificial intelligence; CNN, convolutional neural network; CT, computed tomography; ML, machine learning; MLP, multi-layer perceptron; ROC, receiver operating characteristic. | | --- | | This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
