Feasibility and diagnostic performance of sentinel node biopsy for staging cN0 oral squamous cell carcinoma in a previously treated neck.

ABSTRACT:

Objectives

Staging of the cN0 neck with sentinel node biopsy (SNB) in early-stage oral squamous cell carcinoma (OSCC) is validated in patients with a previously untreated neck. We aimed to investigate the feasibility and diagnostic accuracy of SNB and unexpected drainage patterns in patients with cT1-T2N0 OSCC and a history of previous head and neck cancer comprising treatment of the neck, that is, surgery, radiotherapy, or both.

Methods

Fifty patients with a previously treated neck diagnosed with a new primary or recurrent cN0 OSCC between 2014 and 2021 were included and retrospectively analyzed. Feasibility was assessed by the rate of successfully performed SNB neck staging procedures. Based on follow-up data, the diagnostic performance of SNB was evaluated by calculation
