If the methylene blue assisted technique is superior to the standard approach using the fresh sample in harvesting LNs by surgeons after colectomy for colon cancer, the results contribute to prevention of stage migration and the standardization of therapy for colon cancer, not influenced by the size of the medical facility, the number of doctors and the experienced of harvesting LNs.
