AI总结:

本研究评估对话式AI系统AMIE在乳腺肿瘤治疗中的表现,通过50个合成病例与临床医生对比,发现其优于住院医师和专科培训医师,但逊于主治医师,展示了AI辅助肿瘤决策的潜力与局限。

摘要:

大型语言模型(LLMs)在编码临床知识和以适当的临床推理回应复杂医学查询方面已显示出显著进展。然而,它们在亚专科或复杂医疗环境中的适用性仍未得到充分探索。在本研究中,我们探究了AMIE(一种研究性对话诊断AI系统)在乳腺肿瘤治疗这一亚专科领域中的表现,且未针对这一具有挑战性的领域进行特定微调。为进行此评估,我们策划了一组50个合成乳腺癌病例,涵盖一系列未治疗和治疗难治性病例,并反映了多学科肿瘤委员会进行决策时可获得的关键信息(随本研究公开发布)。我们制定了一份详细的临床评估标准用于评估管理计划,包括病例总结质量、拟议护理计划的安全性以及对化疗、放疗、手术和激素治疗的建议等维度。为提升性能,我们增强了AMIE的推理时能力,使其能够进行网络搜索检索以收集相关且最新的临床知识,并通过多阶段自我批评流程优化其回应。我们在自动化评估和专科临床医生评估下,将AMIE的回应质量与内科住院医师、肿瘤学专科培训医师和普通肿瘤学主治医师进行了比较。在我们的评估中,AMIE优于住院医师和专科培训医师,展示了该系统在这一具有挑战性和重要领域中的潜力。我们进一步通过定性示例展示了诸如AMIE之类的系统如何促进对话式交互以协助临床医生进行决策。然而,AMIE的整体表现逊于肿瘤学主治医师,这表明在考虑前瞻性应用之前仍需进一步研究。

英文摘要:

Large language models (LLMs) have shown remarkable progress in encoding clinical knowledge and responding to complex medical queries with appropriate clinical reasoning. However, their applicability in subspecialist or complex medical settings remains underexplored. In this work, we probe the performance of AMIE, a research conversational diagnostic AI system, in the subspecialist domain of breast oncology care without specific fine-tuning to this challenging domain. To perform this evaluation, we curated a set of 50 synthetic breast cancer vignettes representing a range of treatment-naive and treatment-refractory cases and mirroring the key information available to a multidisciplinary tumor board for decision-making (openly released with this work). We developed a detailed clinical rubric for evaluating management plans, including axes such as the quality of case summarization, safety of the proposed care plan, and recommendations for chemotherapy, radiotherapy, surgery and hormonal therapy. To improve performance, we enhanced AMIE with the inference-time ability to perform web search retrieval to gather relevant and up-to-date clinical knowledge and refine its responses with a multi-stage self-critique pipeline. We compare response quality of AMIE with internal medicine trainees, oncology fellows, and general oncology attendings under both automated and specialist clinician evaluations. In our evaluations, AMIE outperformed trainees and fellows demonstrating the potential of the system in this challenging and important domain. We further demonstrate through qualitative examples, how systems such as AMIE might facilitate conversational interactions to assist clinicians in their decision making. However, AMIE's performance was overall inferior to attending oncologists suggesting that further research is needed prior to consideration of prospective uses.
