Clinicopathological study of submental lymph node metastasis from oral cancer

Abstract

A clinicopathological study was performed on 9 cases of metastasis of the oral cancer to the submental lymph node experienced in our department. As a result, it was found that the metastasis was extensive in these cases with a high incidence of recurrence in the contralateral cervical region. Compared with the submandibular lymph node, the tumor tended to develop outside the lymph node in the early stage for metastatic lesions of the submental lymph node, and the recurrence after radical neck dissection was also more frequently observed in the submental region. Therefore, the metastatic aspect in the submental lymph node apparently differed from that of the submandibular lymph node.
Thus, a more elaborate treatment should be performed in such cases.
