Surgical treatment for well-differentiated thyroid carcinoma invading the laryngotrachea / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the method of surgical treatment for well-differentiated thyroid carcinoma (WDTC) invading the laryngotrachea.</p><p><b>METHODS</b>According to surgical procedure, 21 patients with WDTC invading the laryngotrachea were divided into tumor radical removal group (Group A, n = 5), tumor chisel group (Group B, n = 11) and tumor debulking group (Group C, n = 5).</p><p><b>RESULTS</b>The overall 3-, 5- and 7-year survival rates were 81.0% (17/21), 61.9% (13/21) and 42.9% with better result in Group A (P < 0.001) and Group B (P < 0.03) than in Group C, however, without any significance between Groups A and B (P > 0.05).</p><p><b>CONCLUSION</b>Conservative operation should be considered in most patients with well differentiated thyroid carcinoma invading the laryngotrachea. Only in the presence of intraluminal invasion in the trachea causing hemoptysis and airway obstruction does it require radical operation.</p>
