BACKGROUND: Pre-vascular facial nodes (PV-FNs; perifacial lymph nodes) are supra-mandibular lymph nodes above the inferior border of the mandible. These are not part of routine neck dissection done for OCSCC. These lymph nodes can be sentinel station for metastatic lymph nodes from gingivobuccal complex cancers and are missed during routine neck dissection. It is imperative to include this sentinel station in routine neck dissection to prevent nodal recurrences.
MATERIALS AND METHODS: One hundred thirty-seven patients with GBCC (T1-T4) were prospectively recruited between May 2020 and June 2022 with the intent to evaluate the incidence of PV-FN metastases and clinicopathological factors predicting them.
RESULTS: PV-FN metastases were seen in 26 patients (18.9%; 26/137). The occult metastasis rate was 8.7% (12/137). On multivariate analysis, pathological T4 stage (pT4), LVE positivity, and intermediate-high BGS were statistically significant predictors of PV-FN metastases in our study.
CONCLUSIONS: Incidence of PV-FN metastasis is high (18.9%) in GBCC, which can be potentially the first sentinel station in the lymphatic drainage pattern for this sub-site. Meticulous clearance of this nodal basin is of paramount importance during neck dissection to prevent nodal recurrences.
