摘要:
在乳腺癌HER2评估中,临床评估依赖H&E和IHC图像的结合,但获取两种模态的图像往往受临床条件和成本限制。我们提出了一种自适应双模态预测框架,通过两项核心创新灵活支持单模态或双模态输入:动态分支选择器根据输入可用性激活模态补全或联合推理,以及跨模态GAN(CM-GAN,即Cross-Modal Generative Adversarial Network)实现缺失模态的特征空间重建。该设计将仅使用H&E图像的准确率从71.44%大幅提升至94.25%,使用完整双模态输入时准确率达到95.09%,在单模态条件下仍保持90.28%的可靠性。这种“双模态优先、单模态兼容”的架构无需强制同步采集即可达到接近双模态的准确率,为资源有限地区提供了高性价比的解决方案,显著提升了HER2评估的可及性。
英文摘要:
In breast cancer HER2 assessment, clinical evaluation relies on combined H&E and IHC images, yet acquiring both modalities is often hindered by clinical constraints and cost. We propose an adaptive bimodal prediction framework that flexibly supports single- or dual-modality inputs through two core innovations: a dynamic branch selector activating modality completion or joint inference based on input availability, and a cross-modal GAN (CM-GAN) enabling feature-space reconstruction of missing modalities. This design dramatically improves H&E-only accuracy from 71.44% to 94.25%, achieves 95.09% with full dual-modality inputs, and maintains 90.28% reliability under single-modality conditions. The "dual-modality preferred, single-modality compatible" architecture delivers near-dual-modality accuracy without mandatory synchronized acquisition, offering a cost-effective solution for resource-limited regions and significantly improving HER2 assessment accessibility.
