Abstract
To evaluate the frequency of metastasis to sublevel IIB lymph nodes in patients with squamous cell carcinoma of the oral cavity - related to the site of primary tumor-in patients undergoing therapeutic neck dissection in a large cohort of patients. This work was conducted between September 2013 and June 2016. Cases were selected from out-patient clinic in the national cancer institute, Cairo university. Thirty patients with 30 neck dissection were included in this study. All cases were subjected to surgical resection of the primary site with safety margin according to the standard protocol for each site, functional neck dissection for neck lymph nodes and dissection for sublevel IIB lymph nodes separately. 30 patients were included in this study with 30 neck dissections, Examination of the level IIB proved: positive in 1 cases; the case was SCC of the tongue 9%, all the other cases of oral cavity were negative. Based on our observation and interpretation of the data result on our study we can conclude that: Metastatic spread of oral cavity SCC to level IIB in cases of clinically positive neck (cN+) is rare. Metastasis at sublevel IIB is observed without metastasis at levels IIa, III or IV in one case of tongue SCC
