ESTIMation of the ABiLity of Prophylactic Central Compartment Neck Dissection to Modify Outcomes in Low-risk Differentiated Thyroid Cancer

"total thyroidectomy with bilateral prophylactic central compartment (level VI) neck dissection as defined by the American Thyroid Association \[American Thyroid Association Surgery Working Group, Thyroid 2009\]. This is a standard treatment recognized by the French Society of Otolaryngology Head and Neck Surgery \[French Society of Otolaryngology Head and Neck Sugery\].~\- The number of lymph nodes resected, the number of metastatic nodes, their size and the presence or absence of extranodal spread will be recorded. Due to the large natural variability of the number of lymph nodes retrieved in a prophylactic neck dissection \[Hartl DM, Ann Surg 2012\], no patient will be excluded on the basis of number of lymph nodes. Furthermore, the participating surgeons routinely perform complete central neck dissections, and were chosen to participate in this study due to a homogenous technique among these surgeons \[Hartl DM, World J Surg 2012\]."

This is recognized as a standard treatment by the Francophone Association of Endocrine Surgery
