Abstract

The prognostic influence of different clinicopathologic factors in contralateral lymph node metastases of oral and oropharyngeal squamous cell carcinoma (SCC) has been rarely described in the literature. Prediction of these contralateral metastases may be of relevance because this factor is strongly associated with poor prognosis. This study analyzed the relationship between predictor factors and the development of contralateral metastases in oral and oropharyngeal SCC. A series of 402 cases of oral and oropharyngeal SCC were analyzed retrospectively. Unilateral neck dissection was carried out in 190 patients, bilateral neck dissection in 101, and tumor resection without neck dissection in 111. The log-rank test was used for survival analysis of contralateral metastases. Correlation between different clinicopathologic factors and the presence of contralateral metastases was studied with the chi(2) test for univariate analysis and logistic regression for association of these factors and contralateral metastases in the multivariate analysis (P < .05). Of the patients, 20 (5.1%) had primary positive contralateral metastases in neck dissection specimens and 19 (4.8%) had contralateral recurrences at follow-up. When the 2 groups wer...Continue Reading
