Magseed application for detecting recurrent lymph node metastasis in papillary thyroid cancer: A novel minimally invasive Approach.

Papillary thyroid cancer is associated with lymph node metastasis and tumor recurrence that need repeated surgery, entailing surgical challenges with a high risk of complications such as nerve damage and bleeding. Magseed is a metal coil used to detect non-palpable lesions and is an established modality in breast cancer surgery. In this case series, we explore the feasibility of Magseed in metastasis surgery of papillary thyroid cancer. Under the guidance of ultrasonography, Magseed is injected into the target tissue and intraoperatively detected with a handheld magnetometer probe, Sentimag®. Five patients with recurrence of papillary thyroid cancer were operated on with focused Magseed-guided localization. All patients had repeated surgery and radioiodine treatments. Four of the patients had lymph node metastasis hidden in the fibrosis, and one patient had recurrent tumor tissue on the left side of the larynx. Magseed was easy to use, safe, and precise in detecting the target tissue.
