[Sentinel node navigation surgery for colorectal cancer].
Sentinel nodes (SN) are defined as direct drainage nodes from the primary lesion and the initial sites of micrometastasis. We have been trying to detect sentinel nodes of colorectal cancer using the dying method. The skip metastasis frequency was 15.7% (50 cases) among 318 cases with lymph node metastases. The identification of SN was possible in 110 (98.2%) out of 112 cases. Saltation lymph node metastasis was accepted by 6 examples, but all cases were identified as SN. The diagnostic accuracy of lymph node metastasis by a dying method was 94.5%. In Dukes A cases, 36 of 37 cases (97.2%) were diagnosed correctly. Although there are several remaining issues to be solved, sentinel node technologies would be great tools to establish individualized minimally invasive surgical management of colorectal cancer.
