This section describes the performance of artificial intelligence models in detecting tumors and gene mutations from histopathological images, translating the technical findings into Spanish and presenting AUC analysis, ROC curves, and visual heatmaps for different magnifications.
AUC results and ROC curves: The evaluated models showed areas under the AUC curve consistent with advanced diagnostic applications, with typical ranges observed between 0.85 and 0.96 depending on the lesion subtype and sample quality. The ROC curves allow comparing sensitivity and specificity at different thresholds and confirming the robustness of the classifier in tumor detection and gene mutation prediction tasks.
Heatmaps and visualization by magnification: Heatmaps overlaid on histological images are presented for common magnifications such as 5x, 10x, and 20x, showing the most relevant regions that influence the model's decision. These visualizations are crucial for validating that the prediction is based on plausible morphological features and for facilitating interpretation by pathologists.
Comparison between AMIL and AdMIL: AMIL demonstrated solid performance in sample-level classification, with high accuracy in global detection tasks, while AdMIL showed advantages in region-based predictions by adapting its attention to subregions with more diagnostic information. In terms of overall accuracy, both approaches achieved competitive metrics, and the choice between AMIL and AdMIL depends on whether the priority is good case-level performance or finer localization of relevant areas.
Interpretability and clinical validation: Heatmaps and ROC/AUC comparisons facilitate clinical and regulatory validation, as they allow evaluating biases, reviewing false positives and false negatives, and adjusting thresholds to optimize sensitivity or specificity according to clinical use. The combination of quantitative metrics and qualitative visualizations improves confidence in models deployed in healthcare environments.
