Abstract

Background

Although existing literature provides surgical recommendations for treating occult disease (cN0) in early stage oral cavity squamous cell carcinoma, a focus on late stage OCSCC is less pervasive.

Methods

The records of 162 late stage OCSCC pN0 individuals that underwent primary neck dissections were reviewed. Lymph node yield (LNY) as a prognosticator was examined.

Results

Despite being staged pN0, patients that had a higher LNY had an improved regional/distant control rates, DFS, DSS, and OS. LNY consistently outperformed all other standard variables as being the single best prognostic factor with a tight risk ratio range (RR = 0.95–0.98) even when correcting for the number of lymph nodes examined.

Conclusion

The results of this study showed that lower regional recurrence rates and improved survival outcomes were seen as lymph node yield increased for advanced T-stage OCSCC pN0. This suggests that increasing lymph node yield with an extended cervical lymphadenectomy may result in lower recurrence rates and improved survival outcomes for this advanced stage group.
