N0 설암에서 술 중 파수꾼 림프절 조직검사의 임상적 유용성에 관한 예비고찰

Abstract

Background and Objectives： (SLNB) sems to have the potential to change our attitude toward the surgical treatment of cN0-staged necks in the near future. If SLN localization can predict which patient requires a neck dissection, then such neck dissections may be avoided in patients with negative sentinel nodes, thus reducing the asociated cosmetic deformities and shoulder dysfunction. The purpose of this study is to evaluate the feasibility and predictive ability of the SLN localization technique for patients with squamous cel carcinoma of the tongue. Materials and Method：We tried to localize the SLN with the lymphoscintigraphy preoperatively and the gamma probe intraoperatively, excised it, and performed frozen sections in 6 patients with lateral T1-T2, N0, and M0 squamous cell carcinoma of the tongue. In 3 of them, we performed supraomohyoid neck dissection. Results：We localized the SLN in 6/6 with lymphoscintigraphy and 5/6 with gama probe. The pathologic results of the frozen sections of SLN and neck disection specimen were al negative, with the negative predictive value of SLNB being 100%. Conclusion：the head and neck surgery and is predictive of cervical metastasis. (Korean J Otolaryngol 2003 ;46 :502-7)
