However, utilization of SLNB in the United States remains. We currently determine the elective neck dissection according to the result of the sentinel lymph node biopsy. Objectives: Sentinel lymph node biopsy (SLNB) has been shown to be an accurate technique for staging the neck in early-stage oral cavity squamous cell carcinoma (OCSCC) and has been incorporated in treatment guidelines as an option instead of elective neck dissection (END). The positive predictive value and the negative predictive value were 100% and 98.5%, respectively. From 2002 to 2004, we evaluated its diagnostic accuracy. We started sentinel lymph node biopsy for the clinically node-negative, early-staged oral cavity cancer in December 2002. Sentinel lymph node biopsy is a proven method for staging the neck in patients with early oral cavity squamous cell carcinoma because it results in less. There have been clinical studies on the sentinel lymph node biopsy for the head and neck squamous cell carcinoma, in which the diagnostic accuracy has been reported to be 95-100%. If the biopsy of the sentinel lymph node shows no metastasis, additional neck dissection can be avoided, which reduces the postoperative morbidity. NICE guideline NG36 (recommendation 1.3.5) recommends that all patients with all early oral squamous cell cancer SCC and N0 neck should be offered sentinel.
Evaluation of this sentinel lymph node enables the prediction of the presence of occult lymph node metastasis. Sentinel lymph node is the first lymph node that gets lymphatic drainage from the tumor. The sentinel lymph node biopsy has been developed for this purpose. Because nodal metastasis of SCC is often curable, whereas distant. Therefore, the extent of the elective neck dissection tends to be reduced to minimize the postoperative morbidity. SLNB carries a low risk of complications and false-negative results when performed optimally. The concept of the SLN is based on the orderly progression of. However, this elective neck dissection gives unnecessary risk of complication and morbidity. The sentinel lymph node (SLN) is the first lymph node to drain a metastatic tumor cell that drains via the lymphatic route. Elective neck dissection for the clinically node-negative neck is targeted to diagnose and eradicate the occult lymph node metastasis.
