L. Califano et al., LYMPH-NODE METASTASIS IN SQUAMOUS-CELL CARCINOMA OF THE LIP - A RETROSPECTIVE ANALYSIS OF 105 CASES, International journal of oral and maxillofacial surgery, 23(6), 1994, pp. 351-355
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 simul
taneous neck dissection. All patients were followed up for at least 5
years. Of the 80 patients without palpable lymph nodes, only three dev
eloped lymph-node metastasis. Of the 25 patients with palpable lymph n
odes who underwent modified neck dissection, four had recurrence of ly
mph-node metastasis at a different level. The overall 5-year survival
rate was 97%. The survival rate for patients with lymph-node metastasi
s was 88%.
