淋巴清扫是大多数恶性肿瘤确定癌症准确分期以及彻底切除可能转移的肿瘤的先决条件。虽然淋巴清扫可以改善预后,但由于手术切缘不清,常常会导致术后浮肿或出血。在这项研究中,我们合成了近红外(NIR)荧光纳米探针,将表面不同的甘露糖部分偶联到淋巴结内的巨噬细胞。使用这些近红外纳米探针,我们论证了术中泛淋巴结(PLN)标测和近红外荧光成像系统下实时光学成像的可行性。我们发现,即使是单一甘露糖偶联的ZW800-1也在4h内在淋巴结中显示出特异性摄取,并且多个甘露糖多轮烷有效地突出了PLN,主要器官中的背景信号很低。这项技术可以帮助外科医生在一次静脉注射近红外纳米探头后熟练地识别所有区域淋巴结,从而轻松而安全地进行淋巴清扫。
Lymphadenectomy is a prerequisite for most malignancies to define the precise staging of cancer, as well as resect the possible metastases completely. While it improves prognosis, lymphadenectomy often causes postoperative edema or bleeding because of unclear surgical margins. In this study, we synthesized near-infrared (NIR) fluorescent nanoprobes with conjugating various mannose moieties on the surface to target macrophages in the lymph node. Armed with these NIR nanoprobes, we demonstrated the feasibility of intraoperative pan lymph nodes (PLN) mapping and real-time optical imaging under the NIR fluorescence imaging system. We found that even single mannose-conjugated ZW800-1 showed specific uptake in lymph nodes within 4 h, and multiple mannose-employed polyrotaxanes highlighted PLN efficiently with low background signals in major organs. This technology can help surgeons perform lymphadenectomy with ease and safety by identifying all regional lymph nodes proficiently after a single intravenous injection of NIR nanoprobes.
