Lymph nodes mapping for detection of sentinel nodes in patients with papillary thyroid cancer

摘要: We examined the feasibility of sentinel lymph node biopsy for papillary thyroid cancer. In dye injection method, 1% isosulfan blue was injected around tumor 32 patients intra-operatively, and in radioisotope (RI) colloid 99mTc-tin 23 1 day preoperatively. Lymph mapping detection nodes performed after thyroidectomy central modified lateral neck dissections. All dissected were postoperatively by hematoxylineosin staining to determine whether or not metastasis present. identified 30 (94%) patients. metastases found 14 patients, some had cancer 13 There only false-negative case. Sensitivity accuracy 93% (13/14) 97% (29/30). With RI rate, sensitivity 96% (22/23), 90% (9/10) 95% (21/22), respectively. Our preliminary study indicated that feasible with It may be helpful avoiding unnecessary dissection improving quality life
