Vocal cord paralysis in patients with thoracic esophageal carcinoma

Of 478 consecutive patients with intrathoracic esophageal carcinoma, 5% had vocal cord paralysis. In two thirds of the patients with vocal cord paralysis, the paralysis was caused by a metastatic lymph node located along the recurrent laryngeal nerve. These findings indicate that the possibility exists for radical surgery by esophagectomy and resection of the metastatic lymph node infiltrating the recurrent laryngeal nerve, even in patients with vocal cord paralysis. However, in only two patients was radical surgery accomplished. None of the 24 patients with paralysis survived without disease for more than 1 year. Thus, in patients with vocal cord paralysis, the need for combined therapy should be emphasized.
