ABSTRACT
PURPOSE: Many authors have described clinicopathologic parameters as factors related to cervical lymph node metastasis development in CN0 stage lip cancer. However, predictive factors for occult lymph node metastasis and criteria for elective neck dissection, especially for early tumour, remain undefined. METHODS: A multi-institutional study with 193 consecutive patients with early lip SCC treated from January 1990 to March 2006 was carried out retrospectively to determine factors predicting occult metastasis. RESULTS: The overall late LNM rate was 13% (25/193). In the multivariate logistic regression study, tumour size and pattern of tumour invasion were factors related to the occurrence of late LNM with rates of sensitivity, specifity and accuracy for occult LNM prediction of 50%, 89.5% and 87%, respectively. CONCLUSION: Our results indicate that patients with stage I and II SCC of the lip with tumour size greater than 18 mm and more aggressive pattern of invasion must be considered a high-risk group for LNM and an END should be performed.

BACKGROUND: Pearson's near-total laryngectomy (NTL) is an alternative procedure to total laryngectomy in selected patients with advanced laryngeal cancer. Based on our experience with NTL for >9 years, we present here the functional results, complications, and survival rates. METHODS: A retrospective study was carried out from January 1993 to May 2002. We studied 15 patients with advanced laryngeal, oropharyngeal, and hypopharyngeal cancer who underwent NTL. Survival rates were calculated using the Kaplan-Meier method. RESULTS: The most common complication was fistula (8 of 15) followed by minor aspiration (4 of 15 patients). Eleven patients (73.5%) attained a good voice; 3 patients (19.9%) obtained a bad voice; and 1 did not achieved vocal ability. Three patients (19.9%) had local recurrence; no patients had neck recurrence; and 2 patients (13.3%) had distant metastasis. Six patients (40%) died from their disease, and 2 (13.3%) patients died from other causes. The 3-year actuarial survival rate was 81.6%. CONCLUSIONS: NTL is useful in the treatment of selected patients with advanced laryngeal, oropharyngeal, and hypopharyngeal cancer and results in good control and survival rates. Satisfactory functional results can be attained in the majority of patients. When the surgical margins are positive or close, TL must be carried out.
