Fluorescence-guided surgery (FGS) of cancer is an area of intense development. In the present report, we demonstrate that the telomerase-dependent green fluorescent protein (GFP)-containing adenovirus OBP-401 could label colon-cancer liver metastasis in situ in an orthotopic mouse model enabling successful FGS. OBP-401-GFP-labeled liver metastasis resulted in complete resection with FGS, in contrast, conventional bright-light surgery (BLS) did not result in complete resection of the metastasis. OBP-401-FGS reduced the recurrence rate and prolonged over-all survival compared with BLS. In conclusion, adenovirus OBP-401 is a powerful tool to label liver metastasis in situ with GFP which enables its complete resection, not possible with conventional BLS.
癌症的荧光引导手术(FGS)是一个正在蓬勃发展的领域。在本报告中,我们证明了含端粒酶依赖性绿色荧光蛋白(GFP)的腺病毒OBP - 401能够在原位小鼠模型中标记结肠癌肝转移灶,从而实现成功的荧光引导手术。与传统的明视手术(BLS)不同,OBP - 401 - GFP标记的肝转移灶通过荧光引导手术实现了完全切除。与BLS相比,OBP - 401荧光引导手术降低了复发率并延长了总体生存期。总之,腺病毒OBP - 401是一种用GFP原位标记肝转移灶的强大工具,能够实现其完全切除,而这是传统明视手术无法做到的。
