End-to-End Breast Cancer Radiotherapy Planning via LMMs with Consistency Embedding
This work addresses the clinical workload in radiation oncology by providing an AI-driven solution for tasks like treatment planning and segmentation, though it appears incremental as it builds on existing LMM frameworks.
The authors tackled the problem of automating multiple clinical tasks in breast cancer radiotherapy planning by developing RO-LMM, a large multimodal model with novel fine-tuning and segmentation techniques, achieving promising performance validated across multiple centers.
Recent advances in AI foundation models have significant potential for lightening the clinical workload by mimicking the comprehensive and multi-faceted approaches used by medical professionals. In the field of radiation oncology, the integration of multiple modalities holds great importance, so the opportunity of foundational model is abundant. Inspired by this, here we present RO-LMM, a multi-purpose, comprehensive large multimodal model (LMM) tailored for the field of radiation oncology. This model effectively manages a series of tasks within the clinical workflow, including clinical context summarization, radiation treatment plan suggestion, and plan-guided target volume segmentation by leveraging the capabilities of LMM. In particular, to perform consecutive clinical tasks without error accumulation, we present a novel Consistency Embedding Fine-Tuning (CEFTune) technique, which boosts LMM's robustness to noisy inputs while preserving the consistency of handling clean inputs. We further extend this concept to LMM-driven segmentation framework, leading to a novel Consistency Embedding Segmentation (CESEG) techniques. Experimental results including multi-centre validation confirm that our RO-LMM with CEFTune and CESEG results in promising performance for multiple clinical tasks with generalization capabilities.
