Summary
Brief summary (as posted)
This trial aims to clarify the relationship between carbon nanoparticles labeled lymph nodes and lymph node metastasis in different lymph node regions of colorectal cancer, and to clarify the application value of carbon nanoparticles in lymph node dissection in colorectal cancer surgery.

Arms (1)
- label
- CNP group
- description
- Every patient received endoscopic injection of 0.5 ml CNP suspension (Chongqing LUMMY Pharmaceutical Co., Chongqing, China) into submucosal layer at one point, at the lower margin of the tumor. All patients subsequently underwent laparoscopic or robotic radical resection with D3 LN dissection. Tumor tissue and LNs s were isolated from surgical specimen by the same pathologist. LNs dissection and harvest were on the basis of the Japanese classification of colorectal carcinoma.
