NCT04759820

Brief Summary

Both nano carbon and ICG as lymph node tracers in colorectal cancer have their own value, this study was to contrast two tracers in colorectal cancer surgeries, so as to find out the best lymphnode tracer in colorectal cancer, in order to further improve postoperative lymph node inspection, precise postoperative adjuvant therapy and improve the patients' long-term survival.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Colorectal cancer was confirmed by preoperative fibrocolonoscopy and pathological examination;
  • The operative requirements of the patients included in the study: laparoscopic radical surgery of colon/rectal cancer, indocyanine green group should be used fluorescent laparoscopic (Pinpoint) surgery;
  • The lower edge of the lesion is located more than 10cm from the anus;
  • Age 18 \~ 70;
  • The results of laboratory examination before enrollment met the following surgical conditions: neutrophils (ANC) ≥1.5×109/L, platelets (PLT) ≥ 100×109/L, total bilirubin (TBI) ≤1.5× upper limit of normal (2mg/ dL), alanine aminotransferase (ALT), ascarate aminotransferase (AST) ≤2× upper limit of normal;The coagulation parameters were in the normal range.
  • Patients had no psychological, family, social, or geographical constraints that affected protocol compliance and follow-up time
  • Patient signs informed consent;

You may not qualify if:

  • Under 18 years old or above 70 years old;
  • Other types of colorectal cancer (adenosquamous cell carcinoma, squamous cell carcinoma, neuroendocrine tumor, clear cell carcinoma, spindle cell carcinoma, undifferentiated carcinoma)
  • Rectum cancer less than 10cm from the anus;
  • Previous abdominal surgery;
  • Neoadjuvant therapy was received preoperatively, including radiotherapy and chemotherapy;
  • Due to various reasons, preoperative colonoscopic injection of carbon nanoparticles/indocyanine green labeling was not possible;
  • Intraoperative radical surgery cannot be performed due to various reasons;
  • Acute abdomen: intestinal obstruction, intestinal wringing, peritonitis, etc.;
  • Combined with other site metastasis;
  • Have severe heart, lung, liver and kidney diseases and cannot tolerate surgery;
  • Active stage of liver disease or abnormal liver function, ALT, AST, TBIL more than twice the upper limit of normal value;
  • Renal function impairment, Cr≥2 times the upper limit of normal or BUN≥2 times the upper limit of normal;
  • The subjects' white blood cells are lower than the lower limit of normal value, or their platelets are lower than the lower limit of normal value, or have other diseases of the blood system;
  • People with mental illness or mental retardation who cannot describe their feelings correctly;
  • Severe disorder of coagulation mechanism and bleeding tendency;
  • +5 more criteria
