Clinical significance of sentinel lymph node biopsy in differentiated thyroid cancer

Abstract

Differentiated thyroid cancers are the most common endocrine malignancy and include three main entities: papillary thyroid carcinoma (PTC), follicular thyroid carcinoma (FTC), and Hürthle cell carcinoma (HCC). Papillary thyroid cancer (PTC) is the most common histologic subtype. Was to review different sentinel lymph node biopsy (SLNB) techniques in patients with differentiated thyroid cancer. We also will compare the detection rates and sensitivity of the different detection methods in these patients and assessment of feasibility and side effects of the different techniques. This study was a cross sectional study, Surgical Oncology Department of National Cancer Institute, Cairo University and Damietta Cancer Center, Ministry of Health and Population. Radionuclide technique (lymphoscintigraphy and gamma probe scanning) was successful in 94.6 % (35/37) of the patients as shown in table 4 and relation between SLN and identification by gamma probe. In the 37 patients, the intraoperative frozen biopsy indicated that 22 patients were experiencing SLN metastases, while post-operative routine pathological examination was able to diagnose three additional patients with lymph node metastases.
