CONTEXT: In view of low incidence of contralateral nodal metastasis and increase in the morbidity, the opposite neck is not routinely addressed. However, contralateral nodal metastasis is seen frequently in a certain group of patients. Identifying those factors associated with higher chances of contralateral nodal metastasis may help in optimizing the treatment. AIMS: The aim of this study was to identify prognostic factors associated with contralateral nodal metastasis in cases of buccal mucosa cancers. SETTINGS AND DESIGN: A retrospective audit of 125 patients with squamous cell carcinoma of buccal mucosa at a tertiary cancer center. SUBJECTS AND METHODS: Those cases in which lesions were reaching or crossing midline were included in this study. All cases underwent surgery as primary modality of treatment and had bilateral neck dissection. STATISTICAL ANALYSIS USED: Chi-square test is used for evaluating the variables predicting contralateral nodal metastasis. Finally, a multivariate analysis was performed using binomial logistic regression to identify those variables that were independently associated with the risk of contralateral nodal metastasis. RESULTS: Among 125 patients, 53 cases were node negative. Ipsilateral nodal metastasis was seen in 44/125 (35.2%) patients, 26/125 (20.8%) had bilateral neck node metastasis, and 2/125 (1.6%) had isolated contralateral nodal metastasis. Among these 28 patients with contralateral nodal metastasis, 26 patients had ipsilateral nodal metastasis. Ipsilateral nodal metastasis and skin involvement were independently predictive of contralateral nodal metastasis. CONCLUSIONS: Contralateral nodal metastasis in the absence of ipsilateral nodal metastasis is very rare and frozen section of ipsilateral neck dissection specimen can be an important pointer for addressing contralateral neck.
