Outline

To overcome the limitations of the existing 7-Point Checklist (7PCL), this paper proposes a novel diagnostic framework that integrates the Clinical Knowledge-Based Topological Graph (CKTG) and the Gradient Diagnosis Strategy (GD-DDW) with a data-driven weighting system. CKTG captures internal and external relationships between 7PCL attributes, while GD-DDW prioritizes visual observation, mimicking the diagnostic process of dermatologists. Furthermore, we introduce a multimodal feature extraction method utilizing a dual-attention mechanism to enhance feature extraction through cross-modal interaction and unimodal collaboration, and integrate meta-information to uncover the interactions between clinical data and image features. Evaluation results using the EDRA dataset demonstrated excellent performance in melanoma detection and feature prediction, achieving an average AUC of 88.6%. This integrated system provides clinicians with a data-driven benchmark, significantly improving the accuracy of melanoma diagnosis.

Takeaways, Limitations

Takeaways:
A new melanoma diagnostic framework that overcomes the limitations of the existing 7PCL is presented.
Integrating CKTG and GD-DDW to provide more accurate and robust predictions.
Improving feature extraction performance through multi-modal feature extraction.
Providing clinicians with data-driven benchmarks and improving the accuracy of melanoma diagnosis.
Achieved high AUC (88.6%) on the EDRA dataset.
Limitations:
Further validation of the proposed method's generalization performance is needed (performance evaluation on various datasets).
Lack of detailed description of parameter optimization of CKTG and GD-DDW.
Further research is needed to determine its applicability and utility in real-world clinical settings.
Consideration is needed regarding the size and diversity of the EDRA dataset. Comparative analysis of performance on other datasets is lacking.
