Lymph-node metastasis in squamous cell carcinoma of the lip. A retrospective analysis of 105 cases

During 1975-87, 105 patients with squamous cell carcinoma (SCC) of the lip were surgically treated. All patients underwent radical resection of the tumor. Only the patients with palpable lymph nodes had a simultaneous neck dissection. All patients were followed up for at least 5 years. Of the 80 patients without palpable lymph nodes, only three developed lymph-node metastasis. Of the 25 patients with palpable lymph nodes who underwent modified neck dissection, four had recurrence of lymph-node metastasis at a different level. The over-all 5-year survival rate was 97%. The survival rate for patients with lymph-node metastasis was 88%.
