NCT06135571

Brief Summary

The goal of this observational study is to learn about the the pattern of metastasis of the No.253 lymph node in colorectal cancer. The main questions it aims to answer are: 1. What are the risk factors for metastasis to the No.253 lymph node? 2.What is the prognosis for patients with metastasis to the No.253 lymph node? Patients with descending colon cancer, sigmoid colon cancer, and rectal cancer who undergo curative surgery with dissection of the No.253 lymph node are included in this study

Sampling MethodNon-Probability Sample
Study Population

Patients with left-sided colorectal cancer (left colon cancer, sigmoid cancer, rectal cancer) underwent laparoscopic surgery with dissection of No.253 lymph node.

You may qualify if:

  • Age: 18-75 years;
  • Underwent laparoscopic left hemicolectomy, sigmoid colectomy, or rectal cancer radical surgery.
  • Postoperative pathology confirmed as adenocarcinoma.
  • No evidence of distant metastasis.

You may not qualify if:

  • Previous history of malignant colorectal tumors.
  • Patients who have undergone multiple abdominal-pelvic surgeries.
  • Patients undergoing emergency surgery due to complications such as intestinal obstruction, intestinal perforation, or intestinal bleeding.
  • Surgery did not achieve R0 resection.
  • Patients with concurrent other malignant tumors or multiple primary colorectal cancers.
  • Patients unwilling to sign an informed consent or follow the study protocol for follow-up.
