High-risk squamous cell carcinoma of the ear — A potential role for sentinel node biopsy

Abstract

Background

Squamous cell carcinomas (SCCs) of the external ear have a significant rate of metastasis. The purpose of this study was to present analyzed factors associated with auricular SCC metastasis in order to identify a group that may benefit from sentinel lymph node biopsy (SLNB).

Methods

We performed a retrospective review of all operable SCCs between 2009 and 2014. The association between high-risk features and metastasis were analyzed.

Results

One hundred eighty-nine auricular SCCs were excised. Local recurrence was noted in 11% and 9.5% developed metastases. Cartilage, perineural, and lymphovascular invasion were significantly associated with metastasis, as were increased tumor depth and diameter (P < .001). All patients with metastasis developed nodal disease.

Conclusion

Factors, including poor differentiation, perineural, cartilage, and lymphovascular invasion, are associated with auricular SCC metastasis. Patients with 2 or more high-risk features may benefit from SLNB in order to identify and treat early nodal disease and possibly reduce the risk of further spread.
