BACKGROUND: In this study, a meta-analysis of level IIb metastases in squamous cell carcinoma (SCC) of the oral cavity was conducted. METHODS: Two independent reviewers screened abstracts and full text papers deemed potentially relevant. Data were pooled using a random intercept model. RESULTS: In this analysis, 729 abstracts and 177 full text papers were screened (Kappa statistic 0.8 and 1.0, respectively). A total of 332 patients in 9 papers were included in the analysis. Twenty patients had level IIb metastases (mean, 6%; range, 0% to 10.4%). The pooled percentage of level IIb metastases was 6.0% (95% CI: 3.5-8.6). Only 3 patients with level IIb metastases had isolated nodal disease. Eighty-five percent of those with level IIb metastases had additional nodal disease (95% CI: 64.0-94.8), with IIa being a common denominator among all. CONCLUSION: Level IIb nodal metastases are relatively uncommon in previously untreated SCC of the oral cavity (6%). Furthermore, isolated level IIb nodal disease is uncommon. However, given the quality of evidence to date, it is recommended that dissection of level IIb remain the standard of care in oral cavity squamous cell cancer. Copyright 2009 Wiley Periodicals, Inc.
