The role of sentinel node biopsy in oral squamous cell carcinoma

Abstract

Aim: The purpose of this study was to conduct a systematic review of the published literature to assess the state of the art of this procedure. Sentinel node biopsy (SNB) in oral squamous cell cancer (OSCC) is a novel and proven useful technique alternative to the neck dissection (ND) in the management of OSCC.

Methods: The authors searched PubMed for literature in English published for the last five years, addressing this topic. Prospective studies articles were selected with at least thirty patients studied.

Results: Of 235 studies found, 14 studies met the exclusion and inclusion criteria for this review. The studies selected focused on the role of the SNB in the OSCC, advantages compared to ND and its limitations, testing different solutions and innovations that could implement the conventional procedure. Meta-analysis studies and review articles were also selected in order to perform the introduction and support the discussion. Based upon these findings authors have tried to establish the state of the art of the SNB and authors have highlighted recent advances that improve the sentinel lymphatic node biopsy technique in the future.

Conclusion: SNB is an excellent staging method in OSCC and an interesting alternative to ND. The authors show the most appropriate procedures recommended in the bibliography revised in a trend to depict the actual state of the art.
