研究目的:

乳腺癌腋窝淋巴结(ALN)转移状态的精准术前评估,是制定个体化手术方案、影响患者预后及生存质量的关键。研究显示,前哨淋巴结活检(SLNB)能够准确的对腋窝淋巴结进行分期,但其作为一种侵入性手术,常导致上肢淋巴水肿、感觉障碍等长期并发症,为患者带来经济负担及心理负担。近年来,国际前沿研究(如ACOSOG Z0011、INSEMA试验、SOUND研究)已证实,对经严格筛选的早期乳腺癌患者豁免ALN手术具有安全性与非劣效性,这标志着乳腺癌外科治疗理念正从“最大可耐受治疗”向“最小有效治疗”演进。因此,开发并验证一种能够精准、微创地术前评估ALN状态的新策略,用以安全筛选可豁免SLNB的患者,已成为当前临床实践亟待突破的核心问题。 超声造影(CEUS)技术通过实时动态显影淋巴结的微血管灌注,能敏感地识别出常规超声难以发现的转移灶(表现为灌注缺损、不均匀增强等),在提升诊断敏感性方面展现出巨大潜力。然而,单一影像学检查的阴性预测值(NPV)尚不足以独立支撑豁免SLNB这一重大临床决策。CEUS引导下粗针穿刺活检(CEUS-CNB)通过靶向穿刺可疑区域,有望获取更具代表性的组织进行病理确诊,从而提高诊断效能。但目前该联合策略缺乏高级别循证医学证据支持,其诊断效能在不同分子分型患者中的普适性、以及对新辅助治疗后人群的评估价值等关键科学问题尚未得到系统解答。  

Objectives of Study:

The accurate preoperative assessment of axillary lymph node (ALN) metastasis status is crucial for formulating individualized surgical plans and significantly impacts patient prognosis and quality of life. Sentinel lymph node biopsy (SLNB) has been the standard for accurate axillary staging. However, as an invasive procedure, it is associated with long-term complications such as upper limb lymphedema and sensory disturbances, imposing both economic and psychological burdens on patients. Recent landmark international trials (e.g., ACOSOG Z0011, INSEMA, SOUND) have demonstrated the safety and non-inferiority of omitting ALN surgery in carefully selected patients with early-stage breast cancer. This marks a paradigm shift in breast cancer surgery from "maximum tolerable treatment" towards "minimum effective treatment." Consequently, the development and validation of a novel, precise, and minimally invasive strategy for preoperative ALN assessment to safely identify patients eligible for SLNB omission has become a critical unmet need in contemporary clinical practice.Contrast-enhanced ultrasound (CEUS) technology, by providing real-time dynamic visualization of lymphatic microvascular perfusion, can sensitively identify metastatic foci—manifesting as perfusion defects or heterogeneous enhancement—that are often missed by conventional ultrasound. This presents significant potential for improving diagnostic sensitivity. Nevertheless, the negative predictive value (NPV) of any sin
