Application of carbon nanoparticles in tracing lymph nodes and locating tumors in colorectal cancer / 肿瘤研究与临床

ABSTRACT

With the advancement of surgical techniques, the 5-year survival rate of colorectal cancer has significantly improved. However, incomplete lymph node dissection during operation leads to local recurrence and distant metastasis of the tumor, which has seriously affected the prognosis of patients. In the era of laparoscopy, surgeons' sense of touch is limited, making it difficult to feel and distinguish lymph node metastasis and the location of early colorectal cancer with their hands. The emergence of carbon nanoparticle suspension can help surgeons accurately locate tumors and clean lymph nodes under laparoscopy. This article reviews the clinical application of carbon nanoparticles in lymph node tracing and tumor location in colorectal cancer.
