Early stage oral cavity squamous cell carcinoma (OCSCC) has a significant risk of subclinical nodal metastases, which is the strongest independent prognostic factor for regional recurrence and survival. However current preoperative imaging modalities are unable to identify patients with micrometastases, and an observation strategy has been associated with inferior outcomes when compared to an elective neck dissection. Sentinel lymph node biopsy provides a safe and accurate staging procedure to select the patients who benefit from an elective neck dissection, while avoiding unnecessary surgery in the patients who are node negative. There is recent Level II evidence demonstrating equivalent oncological outcomes when compared with elective neck dissection. However, a multidisciplinary approach is required including reliable mapping of the sentinel lymph node, precise surgical technique and comprehensive histopathological analysis to ensure accurate results are obtained.

Abstract Background Near-Infrared (NIR) fluorescence imaging is a novel technique for intraoperative sentinel lymph node (SLN) identification. It has demonstrated promising results in several surgical specialties. The study aims to evaluate the feasibility of identifying the SLN by indocyanine green (ICG) enhanced NIR endoscopy in squamous cell carcinoma of the oral cavity (OCSCC). Methods Five patients with (cT1-3N0) OCSCC were included. We injected 1–1.25 ml of ICG (5 mg/ml) at four to five points around the primary. After the elevation of a platysma flap and posterior retraction of the sternocleidomastoid muscle, fluorescence images were taken with the IMAGE1 S™ NIR/ICG system to define the SLN(s). We sampled fluorescence marked SLN(s) stratified to lymph node levels, followed by level-specified elective neck dissection. Results The detection of at least one uni- or bilateral SLN (range 1–4) was possible in every case. The fluorescence signal occurred, on average, 4.8 ± 2.6 minutes after injection. There was no case of neck metastasis in SLN (0/13) and non-SLN (0/189). No adverse reactions to ICG occurred. Conclusions Our first results are confirming the concept of SLN concerning OCSCC after the application of real-time NIR fluorescence endoscopy. However, this has to be verified by more extended studies.

Sentinel lymph node (SLN) biopsy has gained attention as a method of minimizing the extent of neck dissection with a similar survival rate as elective neck dissection in oral cancer. Indocyanine green (ICG) imaging is widely used in the field of surgical oncology. Real-time ICG-guided SLN imaging has been widely used in minimally invasive surgeries for various types of cancers. Here, we provide an overview of conventional SLN biopsy and ICG-guided SLN mapping techniques for oral cancer. Although ICG has many strengths, it still has limitations regarding its potential use as an ideal compound for SLN mapping. The development of novel fluorophores and imaging technology is needed for accurate identification of SLNs, which will allow precision surgery that would reduce morbidities and increase patient survival.

The sentinel node, which is not always located at the first-echelon nodal area close to the primary tumor, is the initial recipient of possible metastasis. In order to verify the usefulness of the sentinel lymph node technique in the staging of head and neck cancers, we studied 31 untreated patients with squamous cell carcinoma of the upper airways by injecting them around the primary tumor with technetium 99m albumin microcolloid (99mTc) and submitting them to selective neck dissection with en bloc tumor removal. The nodes were examined after γ-probe identification of the sentinel node(s). No patients were found to have microscopic tumor spread outside the level(s) containing the γ-probe-identified sentinel node(s). In only 1 case was the metastatic node not the γ-probe-posi-tive one, but an adjacent one. Lymphoscintigraphy with 99mTc seems reliable in identifying the sentinel node(s) and might contribute to the reduction of surgical morbidity by reserving therapeutic neck dissection for cases with histologically confirmed nodal metastasis.
