Hybrid supervised deep learning for lung adenocarcinoma diagnosis to optimize surgical strategies
This research introduces a Hybrid-Supervised Framework for Lung Adenocarcinoma (HSFLA) to enhance the accuracy of intraoperative pathological diagnosis of lung adenocarcinoma and optimize surgical strategies. Addressing limitations of manual diagnosis and weakly supervised methods, HSFLA integrates 2D WSI diagnosis, automatic invasive region annotation, WSI registration, and 3D reconstruction for precise tumor volume assessment. Evaluated on 1,161 WSIs, HSFLA achieved 95.6% accuracy, significantly outperforming manual review (84.7%) and weakly supervised learning (66.2% ± 3.0%). Its automatic annotations showed 86.6% concordance with manual pixel annotations and demonstrated genetic interpretability. HSFLA improved pathologists' diagnostic accuracy by 22.9% and led to more appropriate surgical recommendations for 5 out of 70 patients in a prospective study, demonstrating significant clinical utility for AI-assisted pathological assessment and surgical decision-making.
Executive Impact
HSFLA delivers tangible benefits by dramatically improving diagnostic accuracy and efficiency in lung adenocarcinoma. This directly translates to better patient outcomes and optimized resource allocation in clinical pathology.

The Hybrid-Supervised Framework for Lung Adenocarcinoma (HSFLA) offers a novel approach to overcome limitations in intraoperative diagnosis. It integrates 2D WSI diagnosis, automatic invasive region annotation, WSI registration, and 3D reconstruction for precise tumor volume assessment. This leads to significantly improved diagnostic accuracy and aids in optimizing surgical strategies for lung adenocarcinoma patients.
HSFLA achieved 95.6% accuracy in subtype classification, outperforming manual review (84.7%) and weakly supervised learning (66.2% ± 3.0%). It demonstrated 98.15% recall for IA identification and improved AIS vs MIA classification to 94.0%. Invasive lesion labeling consistency with manual annotations was 86.6%.
The framework significantly enhances intraoperative pathological diagnosis, reducing diagnostic time and improving decision-making. Pathologists' manual diagnostic accuracy improved by 22.9% with HSFLA assistance, leading to more appropriate surgical recommendations for 5 out of 70 patients in a prospective study. This establishes quantifiable standards for intraoperative subtyping.
HSFLA integrates a MIL-based network for initial invasive adenocarcinoma screening, a hybrid-supervised dual-channel network for subtype classification with contrastive learning, deep feature matching for slice registration (DeeperHistReg), and a 3D measurement module for invasive lesions, adhering to IASLC diagnostic criteria. The model's robustness is demonstrated even with limited training data and annotations.

Impact on Pathologist Accuracy and Surgical Recommendations
HSFLA significantly improved diagnostic accuracy for pathologists. In a prospective study, the 'human-machine interaction' diagnostic mode led to more precise surgical resection ranges for 5 out of 70 patients. This demonstrates the potential to reduce risks of insufficient or excessive resection.
Key Takeaways:
- 22.9% improvement in manual diagnostic accuracy with HSFLA assistance.
- More appropriate surgical recommendations for 5 patients.
- Quantifiable standards for intraoperative subtyping.
