Pitfalls in the treatment of delayed lymph-node metastases after control of small tongue carcinomas.
Between 1985 and 1992, 13 patients were treated for delayed lymph-node metastases that developed after obtaining control of primary lesions of the tongue. These lesions were treated primarily by radiotherapy or surgical resection; cervical metastases were treated mainly by delayed radical neck dissection (RND). Seven of the 13 patients survived with no evidence of recurrence. The other six patients developed tumors in the neck, and five of these patients died due to uncontrollable disease. In all but one patient, recurrence appeared between the site of the primary lesion and the region of RND, the oral floor and/or the parapharyngeal space. None of the patients with recurrence received radiotherapy in the area between the primary lesion and the site of RND. In contrast, there was no recurrence in patients who received external irradiation to the primary lesion and upper cervical lymph nodes. This review emphasizes the need to direct more attention to the area between the site of the primary lesion and the regional lymph nodes in patients receiving treatment for delayed metastases associated with small carcinomas of the tongue.
