抄録

In squamous cell carcinomas of the oral cavity, spinal accessory lymph node (SALN) metastasis develops infrequently, and the prognosis of the patients with SALN metastasis is extremely poor.<BR>In this paper, patients with SALN metastasis of squamous cell carcinomas of the oral cavity were studied retrospectively. The SALN metastasis was histopathologically confirmed in 9 (5.0%) of 179 patients who underwent radical or modified radical neck dissection. The primary sites of their tumors were the tongue in 6 patients, the lower gingiva in 2, and the buccal mucosa in 1. The risk of SALN metastasis was related to the tumor spread into the oropharynx and the differentiation of the tumor, but not related to the T stage. In the patients with SALN metastasis, the mean total number of involved nodes on the affected side of the neck was 9.4. All of these patients had metastases in multiple groups of neck lymph nodes, and the majority had metastases in the upper and middle jugular groups of nodes. The mean number of involved SALNs was 2.0, and the mean size of these nodes was 0.52 cm in diameter.<BR>The outcome of treatment in the patients with SALN metastasis was poor: 1 patient was alive with no evidence of disease, and 8 patients died of disease with an average duration of survival of 8.0 months after neck dissection.<BR>To improve the prognosis of patients with SALN metastasis, both postoperative irradiation to the neck and intensive adjuvant chemotherapy should be employed.
