INTRODUCTIONS: Thyroid cancer is the most common endocrine malignancy with an incidence equal to 1% of all malignant tumors. Prognostic factors affecting survival are manifold, including in several classifications (AMES, AGES, CORN and TNM). In this sense, the invasion of adjacent structures is one of the most important variables. The authors describe the experience of a single center in surgical treatment of advanced thyroid cancer.
MATERIALS AND METHODS: Between 1986 and 2010 , 1565 patients were undergoing surgery with thyroid cancer. In particular, 1403 interventions were made for differentiated cancer, 97 for medullary carcinoma, 25 for insular carcinoma, 29 for anaplastic carcinoma, 2 for plasmacytoma, and 7 for lymphoma and 2 for angiosarcoma. Among these 896 showed invasion of adjacent structures and / or distant metastases. RESULTS: There were no perioperative deaths or major complications. Surgical procedures consisted of: 13 loboistmectomy, 519 total thyroidectomy (TT), 325 TT with lymphadenectomy of the central compartment, 7 TT with radical lymphectomy, 621 TT with functional lymphectomy, 6 TT with breast lumpectomy, 5 TT with with video-assisted lung metastasectomy, 16-TT with resection and tracheal anastomosis, 6 TT with laryngotracheal resection, 3 TT with laryngectomy, 4 TT with trachetomy, 28 TT with respiratory stent placement, 12 tracheotomy. At present, 1328 patients were free of disease, while 104 showed recurrence. Total of 133 deaths were recorded, all linked to disease relapse.
DISCUSSION: The role of surgery in the treatment of advanced thyroid cancer is still undeniable. In the presence of extracapsular trespassing, in fact, the adoption of interventions demolition permits long-term survival, given the lack of aggressiveness of the tumor differentiated representing the majority of cases. The aim of surgical radicalization addition, even in the presence of distant metastases, it is justified by the possibilities offered by the therapeutic radioiodine treatment, which is not feasible in the presence of significant amounts of thyroid tissue which picks. In the presence of undifferentiated tumors, finally, endoscopic or surgical treatment may be indicated by simple purpose of palliation of respiratory symptoms.
