Mukherjee C, Arora A, Nandi S, Saini S. A Prospective Cohort Study on Neck Lymph Node Mapping in Oral Cancers Using Methylene Blue Dye. Indian J Otolaryngol Head Neck Surg 2024; 76:3330-3337. [PMID: 39130243 PMCID: PMC11306817 DOI: 10.1007/s12070-024-04682-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/01/2024] [Indexed: 08/13/2024] Open
Abstract
In the current scenario, the management of N0 neck in early-stage oral cancer is debatable, whether or not they should undergo elective neck dissection. Most of the time these patients are either over-treated or under-treated. Sentinel lymph node (SLN) biopsy is a good option to identify occult LN in this cohort of patients for guiding neck dissection. With a focus on SLN biopsy using methylene blue dye, this study aims to evaluate its feasibility and accuracy in node-negative oral squamous cell carcinoma. A prospective observational study was conducted involving operable squamous cell carcinoma patients with clinically and radiologically node-negative neck. Methylene blue was injected in the peritumoral area and after that SLN was identified and then neck dissection was completed. Of 47 patients, SLN was identified in 82.98%, with 53.85% having more than two SLN. Common locations were in levels IB, IA and IIA. Occult metastasis was observed in 12.82% of cases, predominantly in T2 patients. Sensitivity, specificity and NPV were 50%, 100% and 88.89% respectively. The study affirms the feasibility and accuracy of methylene blue-assisted SLN biopsy in oral cancer. Despite a high detection rate, methylene blue dye alone should not be used for SLN identification in oral cavity cancer. However, it can be used as an adjunct of lymphoscintigraphy to increase the yield of the procedure. Multi-institutional trials with larger cohorts may provide valuable insights and more information for comprehensively addressing the limitations of this technique and its broader applicability in decision-making, particularly in resource-constrained countries like India where lymphoscintigraphy is not readily accessible.

[PMID: 39082010 PMCID: PMC11284428 DOI: 10.1016/j.heliyon.2024.e34569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 07/08/2024] [Accepted: 07/11/2024] [Indexed: 08/02/2024] Open
Abstract
Background Efficient diagnosis of patients at high risk for invasive aspergillosis (IA) improves the outcome of the disease. Lateral flow assay (LFA) is a novel technology and assessing its diagnostic accuracy is of great significance in the clinical management of IA. Methods A meta-analysis using case-control studies was performed to assess the diagnostic performance of LFA alone or galactomannan (GM) combined with LFA (GM-LFA) as screening tests for IA. The sensitivity, specificity, and summary receiver operating characteristic curves were constructed. Results Nineteen studies with 2838 patients were included. The pooled effect sizes for different indicators included: sensitivity (77 % for LFA and 75 % for GM-LFA), specificity (88 % for LFA and 87 % for GM-LFA), positive likelihood ratio (6.65 for LFA and 12.02 for GM-LFA), negative likelihood ratio (0.26 for LFA and 0.27 for GM-LFA), and the diagnostic odds ratio (25.81 for LFA and 44.87 for GM-LFA). The area under the curve was 0.91 for LFA and 0.94 for GM-LFA with a cut-off value ≥ 0.5. Conclusion The present meta-analysis suggested that LFA or GM-LFA at an optical density index (ODI) cutoff of ≥0.5 was a useful diagnostic tool for IA in patients. The results showed no significant differences in the accuracy of LFA alone and GM-LFA in diagnosing IA. In the clinical diagnosis and treatment of IA, LFA can be recommended if timely results are needed.

Sentinel lymph node biopsy versus elective neck dissection in management of the clinically negative (cN0) neck in patients with oral squamous cell carcinoma: A systematic review and meta-analysis. J Craniomaxillofac Surg 2024; 52:141-150. [PMID: 38195297 DOI: 10.1016/j.jcms.2023.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 09/11/2023] [Accepted: 12/30/2023] [Indexed: 01/11/2024] Open
Abstract
Oral squamous cell carcinoma (OSCC) is the most prevalent type of head and neck cancer, and lymph node metastasis is a crucial prognostic factor that has a direct correlation with the survival rate. The standard procedure for managing clinically negative (cN0) neck in OSCC patients is elective neck dissection (END), but it can lead to various complications that affect the patient's quality of life. Therefore, medical professionals are exploring the use of the sentinel lymph node biopsy (SLNB) to manage cN0 neck in OSCC patients. The aim of this systematic review and meta-analysis was to compare the overall survival (OS) and disease-free survival (DFS) of patients undergoing SLNB and END in the surgical management of early cN0 neck in OSCC patients. To conduct this study, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to report the systematic reviews. The study included all comparative clinical studies, including randomized clinical trials (RCTs), clinical perspective studies, and retrospective studies that compared END to SLNB for early cN0 neck in OSCC patients. The hazard ratio (HR) and risk ratio (RR) with 95% confidence interval (CI) were calculated using comprehensive meta-analysis. The primary outcome variables were OS, DFS, and disease-specific survival (DSS). The secondary outcome variable was the nodal recurrence rate without local or distant metastasis. The GRADE system was used to assess the evidence's certainty. The meta-analysis included 12 clinical studies, comprising three RCTs and seven non-RCTs. The results showed no statistically significant difference between END and SLNB concerning OS (HR = 0.993, CI: 0.814 to 1.211, P = 0.947, low-quality evidence), DFS (HR = 0.705, CI: 0.408 to 1.29, P = 0.21, low-quality evidence), and nodal recurrence (RR = 1.028, CI: 0.969 to 1.090, P = 0.907, low-quality evidence). Additionally, SLNB was non-inferior to END regarding DSS (RR = 1.028, CI: 0.969 to 1.090, P = 0.907, low-quality evidence). In conclusion, this research affirms the safety and precision of SLNB as a means to stage cN0 OSCC patients, with outcomes that are comparable to END in terms of survival and nodal recurrence. Nevertheless, it's crucial to acknowledge that the quality of evidence in this study was relatively low. Therefore, additional RCTs comparing END to SLNB are warranted to validate these results and offer more robust guidance for managing cN0 OSCC patients.

Abstract
BACKGROUND Several studies have demonstrated varying rates of efficacy, reliability, and sensitivity of sentinel lymph node biopsy (SLNB) in identifying occult nodal disease for early stage oral cavity squamous cell carcinoma (OCSCC) depending on the radionuclide agent utilized. No head-to-head comparison of cost or clinical outcomes of SLNB when utilizing [99mTc]tilmanocept versus [99mTc]sulfur colloid has been performed. The goal of this study was to develop a decision model to compare the cost-effectiveness of [99mTc]tilmanocept versus [99mTc]sulfur colloid in early stage OCSCC. PATIENTS AND METHODS A decision model of disease and treatment as a function of SLNB was created. Patients with a negative SLNB entered a Markov model of the natural history of OCSCC parameterized with published data to simulate five states of health and iterated over a 30-year time horizon. Treatment costs and quality-adjusted life-years (QALYs) for each health state were included. The incremental cost-effectiveness ratio (ICER) was then estimated using $100,000 per additional QALY as the threshold for determining cost-effectiveness. RESULTS The base case cost-effectiveness analysis suggested [99mTc]tilmanocept was more effective than [99mTc]sulfur colloid by 0.12 QALYs (7.06 versus 6.94 QALYs). [99mTc]Tilmanocept was more costly, with a lifetime cost of $84,961 in comparison with $84,264 for sulfur colloid, however, the overall base case ICER was $5859 per additional QALY, well under the threshold for cost-effectiveness. Multiple one-way sensitivity analyses were performed, and demonstrated the model was robust to alternative parameter values. CONCLUSION Our analysis showed that while [99mTc]tilmanocept is more costly upfront, these costs are worth the additional QALYs gained by the use of [99mTc]tilmanocept.

Abstract
Cervical lymph node metastases from head and neck squamous cell cancers significantly reduce disease-free survival and worsen overall prognosis and, hence, deserve more aggressive management and follow-up. As per the eighth edition of the American Joint Committee on Cancer staging manual, extranodal extension, especially in human papillomavirus-negative cancers, has been incorporated in staging as it is important in deciding management and significantly impacts the outcome of head and neck squamous cell cancer. Lymph node imaging with various radiological modalities, including ultrasound, computed tomography and magnetic resonance imaging, has been widely used, not only to demonstrate nodal involvement but also for guided histopathological evaluation and therapeutic intervention. Computed tomography and magnetic resonance imaging, together with positron emission tomography, are used widely for the follow-up of treated patients. Finally, there is an emerging role for artificial intelligence in neck node imaging that has shown promising results, increasing the accuracy of detection of nodal involvement, especially normal-appearing nodes. The aim of this review is to provide a comprehensive overview of the diagnosis and management of involved neck nodes with a focus on sentinel node anatomy, pathogenesis, imaging correlates (including radiogenomics and artificial intelligence) and the role of image-guided interventions.

Abstract
UK national guidelines in 2016 recommended that sentinel lymph node biopsy (SLNB) should be offered to patients with early oral squamous cell carcinoma (OSCC). We review the establishment of an OSCC SLNB service with specific consideration to resources, service implications and patient outcomes. A review of processes was performed to identify key stages in establishing the service, and subsequently a retrospective cohort study consisting of 46 consecutive patients with T1/T2 N0 OSCC was undertaken. The key stages identified were: coordinating a nuclear medicine pathway and reliable cost-appropriate pathology service, constructing a Trust business case, and gaining approval of a new interventional service policy. A median (range) of 3.3 (1-8) sentinel nodes (SLN) were removed, with 17 patients having a positive SLN. The negative predictive value of SLNB was 100%, with 12 having a SLN outside the field if elective neck dissection (END) was planned. There was a significantly increased risk of a positive SLN with increasing depth of invasion (DOI) (p=0.007) and increased diameter (p=0.036). We also identified a longer-than-ideal time to completion neck dissection and inadequate ultrasound follow up of negative SLNB patients. Establishment of a service requires careful planning. Our results were in keeping with those reported in the literature, and showed that SLNB for OSCC has a high negative predictive value and can identify at-risk SLN outside the traditional END levels, even in well-lateralised tumours. Our findings show that DOI and size of SLN were significantly associated with a positive SLN, and also identified areas requiring improvement.

Abstract
The aim of this comprehensive review is to describe and analyze the role of the sentinel node mapping in head and neck cancers. For this purpose, head and neck neoplasms have been categorized in cutaneous malignancies and neoplasms of the upper aerodigestive tract. A concise description of lymphatic drainage will be the "prelude" for each section, as well as the description of the injection techniques, when specific. Concisely, the attention has been focused on detection rate of the sentinel node by lymphoscintigraphy for each cancer, and for those patients in which the sentinel lymph node has been identified, true-positives rates, false-negative rates, and overall accuracy has been pointed out. Overall, in cutaneous neoplasms of the head and neck, the detection rate is higher than 90%, however the false-negative rate is still an issue, in particular in melanoma, inducing the need for newer developments. In fact, new tracers and techniques are already available, while prospective multicenter trials exploring the outcome impact are needed in the near future. For the upper aerodigestive tract and in particular oral cavity and oropharynx, sentinel lymph node identification by lymphoscintigraphy allows avoiding unnecessary neck dissection and/or node irradiation. Even in this case, the main limit remains the risk of false-negative rates. While, for patients affected by laryngeal and hypopharyngeal cancers the data seem very limited and, although the feasibility has been demonstrated, performances of this lymphoscintigraphy still need to be confirmed by multicenter studies.

Abstract
The purpose of this study was to present our experience and validate the use of sentinel lymph node (SLN) mapping in patients with head and neck cancers. A retrospective review of a pro-spectively collected database of patients with a diagnosis of squamous cell carcinomas of the head and neck from 2008 to 2011 was done. The group consisted of a total of 20 patients. The first node(s) highlighted with blue, or identified as radioactive by Tc99-sulfur radioactive colloid, was (were) identified as the SLNs. In the first seven patients, formal modified neck dissection was performed. In the remaining 13 patients, only a SLN biopsy procedure was done. At least one SLN was identified in all 20 patients (100%). Only one patient (5%) had positive nodes. In this case, the SLN was also positive. In the remaining 19 cases, all lymph nodes were negative. After an average of 24 months of follow-up, there have been three local recurrences (15%) but no evidence of distant metastatic disease. SLN mapping in head and neck cancers is a feasible technique with a high identification rate and a low false-negative rate. Although the detection rate of regional metastatic disease compares favorably with published data as well as the disease-free and overall survival, further studies are warranted before considering this technique to be the “gold standard” in patients with oral squamous cell carcinoma and a negative neck by clinical examination and imaging studies.

Abstract
In clinical N0 (cN0) cases with head and neck squamous cell carcinoma (HNSCC), a treatment selection is still controversial: elective neck dissection or watchful waiting. We focused on sentinel lymph node (SLN)-targeted therapy using the urokinase-type plasminogen activator (uPA)-dependent oncolytic Sendai virus "BioKnife." The objectives of this study were to investigate BioKnife migration into SLNs and elucidate its antitumor effect on lymph node metastases (LNM). We established an orthotopic nude mouse model of HNSCC, with LNM being frequently induced. We inoculated HSC-3-M3, human highly metastatic tongue squamous cell carcinoma cells, in the tongue of the nude mice, and after 2 weeks, we injected BioKnife into the primary tumor. We tracked BioKnife migration into the SLNs by immunostaining, RT-PCR, and an in vivo imaging system. We also examined its antitumor effects and mechanisms through serial section analysis of lymph nodes. GFP reporter expression was clearly visible in the lymph nodes of virus groups, which corresponded to SLNs. Relative GFP mRNA was significantly increased in both the tongues and lymph nodes in the virus groups compared with that in the control group (P < 0.05). Serial section analysis showed that BioKnife infected cancer cells and exhibited significant antitumor effect against LNM compared with the control groups (P < 0.05). We detected apoptosis in LNM infected by BioKnife. BioKnife migrated into SLNs after its injection into the primary tumor and effectively suppressed LNM, suggesting that SLN-targeted therapy using BioKnife has great potential to provide a novel and promising alternative to elective neck dissection in cN0 patients with HNSCC.

Sentinel lymph node biopsy in cN0 neck management of parotid cancer. Sci Rep 2019; 9:8339. [PMID: 31171810 PMCID: PMC6554268 DOI: 10.1038/s41598-019-44790-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 05/24/2019] [Indexed: 12/24/2022] Open
Abstract
Our goals was to evaluate how sentinel lymph node biopsy (SLNB) benefit neck management in patients with parotid cancer. Patients diagnosed with cN0 parotid cancer by preoperative fine needle puncture were prospectively enrolled. The neck status was evaluated by SLNB. If node metastasis was proved by SLNB, a neck dissection of level I-V a was performed, or a wait-and-see policy was conducted for the patient. All related information was extracted and analyzed. Positive SLNB result occurred in 33 (16.7%) patients, and level II metastasis was noted in 100% of the patients. Isolated level III metastasis was noted in 3 (9.1%) patients. During our follow-up with mean time of 49.5 months, 20 patients developed regional recurrence, in which 6 patients had neck dissection as part of their initial management. All the recurrent neck disease was successfully salvaged. Therefore, SLNB was a reliable procedure for neck management in parotid cancer.

Abstract
The standard local treatment for early-stage tongue cancer with no clinical lymph node metastases is partial glossectomy. The frequency of occult lymph node metastasis is ~20-30%. Thus, whether prophylactic neck dissection with glossectomy or glossectomy alone should be performed has been a controversial issue since the 1980s. Both treatments have advantages and disadvantages; however, especially in cases involving prophylactic neck dissection, surgical invasion and complications including the cosmetic disadvantage caused by neck skin incision, accessory nerve paralysis or facial nerve (mandibular marginal branch) paralysis, stiffness of the shoulder or neck and a feeling of neck tightness have been considered issues that could be solved by providing less-invasive treatment to the 70-80% of patients without occult lymph node metastasis. A more accurate preoperative diagnosis and strict follow-up are required to provide minimally invasive treatment while ensuring the therapeutic effect. It is also necessary to narrow down the target based on the risk-benefit balance. The depth of invasion should be considered in cases involving oral cavity malignancies. This was also taken into account in recent revisions of eighth edition of the TNM Classification of Malignant Tumors and it is an important factor for N0 neck management. This review article summarizes previous and recent reports on neck management, focusing on the risk-benefit and future perspectives of the diagnosis and treatment of early-stage oral tongue cancer. This effort is an attempt to establish treatment from the patient's point of view, with the patient's quality of life taken into account.

Abstract
Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient’s treatment goals.

Abstract
OBJECTIVES The diagnostic efficacy of sentinel lymph node biopsy(SLNB) in early oral squamous cell carcinoma(OSCC) still remains controversial. This meta-analysis was conducted to assess the diagnostic value of SLNB in clinically neck-negative T1-2 OSCC. METHODS A systematic literature search for relevant literature published up to September 11, 2016 was conducted in PubMed, Embase, Web of Science, Cochrane Library and ClinicalTrials, and the reference lists of eligible studies were examined. Data from different studies were pooled to estimate the summary sentinel lymph node(SLN) identification rate, sensitivity, negative predictive value. Summary receiver operator characteristic curve(SROC) was plotted and area under the SROC curve (AUC) was calculated to evaluate the overall diagnostic efficacy. Threshold effect was assessed with use of the spearman correlation coefficient. Between-study heterogeneity was tested using the Q tests and the I2 statistics. Subgroup analyses were conducted in view of the greater effect of different study characteristics on diagnostic efficacy of SLN. Deeks' funnel plot asymmetry test was performed to evaluate publication bias. Sensitivity analysis was evaluated through omitting studies one by one and comparing the pooled results of random-effects model and fixed-effects model. All analyses were performed using Review Manager (version 5.3.5), Meta-DiSc (version 1.4), Comprehensive Meta Analysis (version 2.0) and STATA (version 12). RESULTS 66 studies comprising 3566 patients with cT1-2N0 OSCC were included in this meta-analysis. The pooled SLN identification rate was 96.3%(95% CI: 95.3%-97.0%). The pooled sensitivity was 0.87 (95% CI: 0.85-0.89), pooled negative predictive value was 0.94 (95% CI: 0.93-0.95), and AUC was 0.98 (95% CI: 0.97-0.99). Subgroup analyses indicated that SLN assessment with immunohistochemistry(IHC) achieved a significantly higher sensitivity than without IHC. CONCLUSIONS This meta-analysis suggests that SLNB has a high diagnostic accuracy in cT1-2N0 oral squamous cell carcinoma, and is an ideal alternative to elective neck dissection. Furthermore, the use of IHC can significantly improve SLNB diagnostic sensitivity for early OSCC.

Abstract
Oral cancers in India are very common. SLNB (sentinel lymph node biopsy) for the management of the cN0 neck provides proper staging with less morbidity. The study aims at assessment of the technical feasibility and accuracy of SLNB. Two by two table and Kappa statistic was used to compare SLN and END. In 14 cases out of 16 cases, SLN was identified. Sensitivity and specificity of 100 % were found. One hundred percent agreement was observed between SLN and END using kappa statistics. A meta-analysis of 19 studies showed 97.7 % sentinel node identification rate and 92.6 % sensitivity with a false negative rate of 3 %. In patients with N0 neck and negative SLN, neck dissection can be avoided decreasing morbidity of SOND. SLN biopsy has potential to become standard of care for managing N0 neck; however, long-term oncological results need to be evaluated.

Abstract
OBJECTIVE A recent study identified a survival benefit with prophylactic neck dissection (ND) at the time of primary surgery as compared with watchful waiting followed by therapeutic neck dissection for nodal relapse, in patients with cN0 oral squamous cell carcinoma (OSCC). Alternative management of cN0 neck cancer is recommended to minimize the adverse effects of ND, indicating the need for sentinel node biopsy (SNB) and limited neck dissection. We conducted a multicenter Phase II study to examine the feasibility of SNB for clinically N0 OSCC. METHODS Previously untreated N0 OSCC patients (n=57) with clinical late-T2 or T3 tumors were enrolled across 10 institutions. SNB navigated with multislice frozen section analysis of sentinel nodes (SNs) and SNB supported sentinel node lymphatic basin dissection (SN basin dissection) were performed in a one-stage procedure. The endpoint was to investigate the rate of false-negative metastases after SN basin dissection and SNB alone. RESULTS Most tumors were late-T2 lesions (n=50; 87.7%). SNs were identified in all patients. A total of 196 SNs were detected. Among these SNs, 35 (17.8%) were positive for metastasis (9 in level I, 12 in level II, 12 in level III, 1 in level V and 2 in the contralateral region of the neck). The false-negative rate of SNB supported by SN basin dissection and SNB alone was 4.5% and 9.1%, respectively. The concordance of the SN status in intraoperative frozen sections with the permanent histopathology was 97.4% (191/196). The sensitivity and specificity of intraoperative pathological evaluation were 85.7% (30/35) and 100% (30/30), respectively. The 3-year overall survival (OS) and disease-free survival was 89.5% and 82.5%, respectively. The OS of SN-negative patients was significantly longer than that of SN-positive patients (P=0.047). CONCLUSION The current study verified that SN basin dissection was a useful back-up procedure for SNB performed as a one-stage procedure, showing a low false-negative rate. SNB alone is an appropriate staging method for patients with clinical N0 staging, and a reliable procedure to determine the appropriate levels for neck dissection.

Abstract
The effect of preoperative radio chemotherapy on lymphatic drainage and intraoperative gamma probe-guided sentinel lymph node detection has yet not been investigated. In this study, we study 13 patients with SCC. Sentinel lymph node (SLN) imaging of the patients was performed using SPECT-CT. Special care was taken to use identical injection sites for both studies. Imaging comprised planar and SPECT, iterative reconstruction and were viewed with the co-registered CT image. The results were validated by comparison with the histological results of intraoperative gamma probe detection and histology of the completed neck dissection. Identical SLNs were found in 6/13 patients. In 2/13 cases SLN biopsies were false-negative. In 4/13 patients preoperative SLN imaging identified more/additional nodes than the initial imaging, whereas fewer nodes were seen in 3/13 patients. Neither the primary tumor site nor the TNM stage was predictive for changes in the lymphatic drainage pattern. No constant effect of irradiation could be demonstrated. Preoperative radio chemotherapy has an unpredictable influence on the lymphatic drainage pattern in HNSCC. Consequently, the intraoperative gamma probe-guided sentinel lymph node detection after radio chemotherapy does not reveal the SLN of carcinogenesis. Thus, we advise fused functional/anatomical imaging (SPECT-CT) before and after radiochemotherapy if the SLN concept is utilized in HNSCC.

Abstract
Objective To test the feasibility of contrast-enhanced ultrasound (CEUS)–guided sentinel lymph node biopsy (SNB) of the head and neck in a porcine model. Study Design and Setting In this prospective, non-randomized study, methylene blue and Sonazoid were injected into the lateral tongue or floor of mouth (FOM) of four swine. Real-time CEUS was used to identify contrast in the lymphatic channels flowing to the sentinel lymph node (SLN). Endoscopic or open SNB was performed. Neck dissection was then performed, and the residual nodal packet was examined for remaining contrast-enhancing or blue dye–stained nodes. Results In all eight procedures, the SLN was visualized with ultrasound and blue dye. Seven procedures identified a single SLN, and one identified two SLNs. Subsequent neck dissections revealed no other nodes containing methylene blue or contrast in the nodal specimen or operative bed. Conclusion/Significance CEUS-guided SNB of the head and neck in swine is feasible, with success comparable to blue dye–guided SNB. This technique may offer several advantages over traditional techniques, and warrants further study.

Abstract
OBJECTIVE: To assess the feasibility of endoscopic sentinel node biopsy (SNB) using a tracer dye in a pig model. STUDY DESIGN AND SETTING: This was a prospective, nonrandomized experimental study in Yorkshire pigs. The posterolateral tongues of three animals were injected with a one-to-one solution of carbon dye to methylene blue dye. Endoscopic SNB was performed and stained lymph nodes identified and retrieved, followed by an open dissection to recover any remaining nodes. Specimens were analyzed by a pathologist for staining, size, and structural integrity. RESULTS: Six unilateral endoscopic SNBs were performed without complications. During endoscopic dissection, gross blue-staining of a sentinel node was noted in four of six dissections (66%). One of six sentinel nodes demonstrated histologic evidence of carbon staining. Structural integrity of all nodes was intact upon histological evaluation. CONCLUSION/SIGNIFICANCE: Endoscopic cervical SNB in pigs is feasible but has limitations based on lymph node size and reliability of tracer dyes. Further study is warranted to perfect tracer dyes and retrieval methods to improve this technique.

Abstract
Regional metastases are a prominent feature of mucosal-associated head and neck squamous cell carcinomas and are an important prognostic factor. Sentinel lymph node biopsy (SLNB) is one modality that has potential to add to the accuracy of neck staging, although it is currently not used as widely in the head and neck as it is in other areas such as breast cancer. We review the efficacy of SLNB in head and neck mucosal squamous cell carcinomas and provide an overview of current practice and include details of technical advances.

Abstract
BACKGROUND The purpose of this study was to examine the diagnostic accuracy of detecting lymph node metastases and to identify predictive and prognostic clinicopathological factors in patients with oral squamous cell carcinoma (OSCC) undergoing sentinel lymph node biopsy (SLNB). METHODS All patients diagnosed with cT1 to T2N0 OSCC who underwent a diagnostic SLNB between 2007 and 2013 were included. RESULTS We identified 253 patients, of whom 27% had a positive sentinel lymph node (SLB). The false-negative rate, sensitivity, and negative predictive value (NPV) were 5%, 88%, and 95%, respectively. Patients with micrometastases as well as macrometastases had a separately, significantly shorter disease-specific survival than patients with pN0 disease. In a logistic regression model, the maximum tumor thickness, perineural invasion, and differentiation grade were independent predictive factors for the presence of metastases. CONCLUSION These data support the use of the SLNB technique as an accurate and safe staging tool in patients with OSCC with a cN0 neck. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1033-E1040, 2016.

Abstract
Introduction Elective neck dissection is recommended in cases of oral cavity squamous cell carcinoma without lymph node metastasis because of the risk of occult metastasis. Objective The present study aimed to evaluate predictive factors for occult lymph node metastasis in patients with oral cavity squamous cell carcinoma treated with elective neck dissection and their impact on overall and disease-free survival. Methods Forty surgically treated patients were retrospectively included. Results Ten cases (25%) had lymphatic metastasis. Of the studied variables, perineural and angiolymphatic invasion in addition to tumor thickness were statistically associated with lymph node metastasis. Only angiolymphatic invasion was identified as an independent risk factor for occult metastasis in the logistic regression (OR = 39.3; p = 0.002). There was no association between overall and disease-free survival with the presence of occult lymph node metastasis. Conclusion Metastatic disease rate was similar to that found in the literature. Perineural and angiolymphatic invasion and tumor thickness were associated with occult metastasis, but only angiolymphatic invasion showed to be an independent risk factor

Abstract
Occult spread to regional lymphatics occurs in a significant percentage of patients with early-stage oral cavity cancer. While elective neck dissection continues to be the gold standard for assessing for the presence of occult regional disease, the optimal management strategy continues to evolve. Increasingly, sentinel lymph node biopsy is being recognized as a viable alternative to elective neck dissection for staging the neck in early-stage oral cavity cancer. In this article, we examine the evidence supporting sentinel lymph node biopsy for early-stage oral cancer and provide an update on some of the novel developments in this field.

Abstract
Sentinel Lymph Node (SLN) biopsy using a combination of radioisotopes and blue dyes have a good accuracy rate in predicting subclinical neck nodal metastases in head and neck cancers. However, the limited availability of lymphoscintigraphy facilities in India requires exploration of alternative methods of SLN detection. We evaluated the feasibility of using methylene blue dye alone in detecting SLN in cN0 early oral cancers. 32 patients with cN0 early (T1, T2) oral squamous cell cancers underwent SLN biopsy using peri tumoural methylene blue dye injection. Blue dye stained (SLN) nodes were sent for frozen section analyses. Patients who had microscopic metastases in SLN underwent modified radical neck dissections and the rest underwent selective neck dissections. Paraffin sections and IHC studies were done on all nodes. SLN was identified in 29 patients (Identification rate = 90.6 %) of which SLN was positive for metastases on frozen section in 5 patients. The sensitivity, specificity and NPV of SLN with frozen section were 80 %, 95.8 % and 95.8 % respectively. IHC with cytokeratins increased the sensitivity (100 %) and NPV (100 %) at the loss of specificity (87.5 %). Methylene blue dye alone can be successfully used for SLN identification in early oral cancers with a good accuracy and sensitivity. This method will be of use especially in resource limited countries and centres where nuclear medicine facilities are not widely available. However, it has to be validated by larger randomised multi institutional trials for wider applicability. Immunohistochemistry increases the sensitivity and negative predictive value of SLN but its applicability in real time decision making is limited.

Abstract
OBJECTIVE The aim of this study was to examine the expression of several cancer-related long non-coding RNAs (lncRNAs) in patients with tongue squamous cell carcinoma (TSCC) and to explore its clinical significance. STUDY DESIGN A total of 94 TSCC tissue specimens and matched adjacent normal tissue specimens were collected from patients undergoing surgery for TSCC. Differences in the expression of cancer-related lncRNAs were examined via quantitative reverse transcriptase polymerase chain reaction. WST-1 assay and transwell migration assay were carried out to estimate the proliferation and migration abilities of TSCC cells with different expression levels of urothelial cancer-associated 1 (UCA1) lncRNA. RESULTS The expression levels of lncRNA UCA1 were significantly elevated in TSCC tissues (P < .0001) and were statistically correlated with lymph node metastasis (P = .0371). Over-expression of UCA1 lncRNA could promote metastatic but not proliferation ability of TSCC cells. CONCLUSIONS Expression of UCA1 lncRNA was enhanced in TSCCs and may play a role in tumor metastasis.

Abstract
OBJECTIVES Results of the Dutch multi-institutional trial on sentinel lymph node (SLN) biopsy in oral cancer. PATIENTS AND METHODS Patients were consecutively enrolled from 4 institutions, with T1/T2 oral cancer and cN0 neck based on palpation and ultrasound guided fine needle aspiration cytology. Lymphatic mapping consisted of preoperative lymphoscintigraphy. For intraoperative SLN detection a gamma-probe was used and in some patients additional blue dye. SLN negative patients were carefully observed, SLN positive patients were treated by neck dissection, radiotherapy or a combination of both. Endpoints of the study were risk of occult lymp node metastases, neck control, accuracy, 5-year disease-free survival (DFS), overall survival (OS) and disease-specific survival (DSS). RESULTS Twenty of 62 patients (32%) had positive SLNs. Macrometastases were found in 9 patients, micrometastases in 8, and isolated tumour cells in 3 patients. Median follow-up was 52.5 months. Of the 42 SLN negative patients, 5 developed a regional recurrence of whom 4 patients could be successfully salvaged. DFS, OS and DSS of SLN negative patients were 72.0%, 92.7% and 97.4%, and for SLN positive patients these numbers were 73.7%, 79.7%, 85.0%, respectively (DFS: p=0.916, OS: p=0.134, DSS: p=0.059, respectively). Neck control rate was 97% in SLN negative and 95% in SLN positive patients. Sensitivity was 80% and negative predictive value 88%. CONCLUSION SLN biopsy is able to reduce the risk of occult lymph node metastases in T1/T2 oral cancer patients from 40% to 8%, and enables excellent control of the neck.

Abstract
OBJECTIVE Sentinel node navigation surgery using real-time, near-infrared imaging with indocyanine green is becoming popular by allowing head and neck surgeons to avoid unnecessary neck dissection. The major drawback of this method is its quick migration through the lymphatics, limiting the diagnostic time window and undesirable detection of downstream nodes. We resolved this problem by mixing indocyanine green (ICG) with phytate colloid to retard its migration and demonstrated its feasibility in a nude mouse study. STUDY DESIGN Experimental prospective animal study. SETTINGS Animal laboratory. SUBJECTS AND METHODS Indocyanine green at 3 concentrations was tested to determine the optimal concentration for sentinel lymph node detection in a mouse model. Effect of indocyanine green with phytate colloid mixture solutions was also analyzed. Indocyanine green or mixture solution at different mixing ratios were injected into the tongue of nude mice and near-infrared fluorescence images were captured sequentially for up to 48 hours. The brightness of fluorescence in the sentinel lymph node and lymph nodes further downstream were assessed. RESULTS Indocyanine green concentration >50 μg/mL did not improve sentinel lymph node detection. The addition of phytate colloid to indocyanine green extended the period when sentinel lymph node was detectable. Second echelon lymph nodes were not imaged in mice injected with the mixture, while these were visualized in mice injected with indocyanine green alone. CONCLUSION This novel technique of ICG-phytate colloid mixture allows prolonged diagnostic time window, prevention of downstream subsequent nodes detection, and improved accuracy for the detection of true sentinel lymph nodes.

Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy of sentinel lymph node biopsy (SLNB) in early head and neck squamous cell carcinoma (HNSCC). METHODS The PubMed database was searched for studies published before October 31, 2012. Pooled values for the sentinel lymph node identification rate, sensitivity, false-negative rate, negative predictive value, and accuracy were calculated. RESULTS A total of 16 studies (987 patients) was included. The pooled identification rate, sensitivity, false-negative rate, negative predictive value, and accuracy were 95.2%, 86.3%, 13.7%, 94.2%, and 95.0%, respectively. The subgroup with high methodological quality showed a mean identification rate of 95.4% for SLNB validation trials and 94.2% for SLNB alone trials, and mean sensitivity of 91.0% for SLNB validation trials and 84.2% for SLNB alone trials. CONCLUSION The SLNB procedure has shown a high sensitivity rate, but the pooled sensitivity and false-negative rate were worse in SLNB alone trials than in SLNB validation trials.

Abstract
CONCLUSION Feasibility of intraoperative 3D imaging with freehand (fh) SPECT for sentinel lymph node (SLN) biopsy in head and neck cancer (HNC) could be demonstrated. Controlled clinical studies are needed to evaluate its accuracy and impact on patient morbidity. OBJECTIVES The clinical N0 neck in HNC needs improvement in management to sufficiently detect occult neck disease but to spare patients from potential morbidity by elective neck dissection. The SLN concept has potential to accurately stage the neck with low morbidity. METHODS fhSPECT is a 3D tomographic imaging modality with a gamma probe system combined with an infrared optical tracking system. Five patients with HNC and clinical N0 neck were recruited. Scanning for SLN using fhSPECT was performed before excision and selective neck dissection and specimens were analyzed histopathologically. RESULTS Preoperatively, a total of nine SLNs were located in five patients with fhSPECT. SLNs in three patients were positive for metastatic disease; in two patients the SLNs were tumor-free. No residual radioactivity was found in the neck in any of the patients after extirpation of SLNs. fhSPECT acquisitions took 2.6 ± 0.4 min. No metastatic lymph nodes were detected in any other node harvested during subsequent selective neck dissection in any patients.

Abstract
CONCLUSION This is the first report on human sentinel node (SN) detection by interstitial magnetic resonance (MR) lymphography with superparamagnetic iron oxide (SPIO) in tongue cancer patients who also underwent lymphoscintigraphy. Our results indicate that further studies are warranted, as this novel method may replace current scintigraphic techniques. OBJECTIVES To examine the feasibility of interstitial MR lymphography using SPIO for SN detection in the head and neck region. METHODS MR images were acquired sequentially at 10 min, 30 min, and 24 h after submucosally injecting 0.1 ml SPIO (ferucarbotran) around the tumor in three patients with tongue cancer without cervical lymph node metastasis (clinical T2N0M0). RESULTS The SNs were clearly visualized in the 10 min interstitial MR lymphography images and were completely concordant with those visualized by (99m)Tc-radiocolloid lymphoscintigraphy and a gamma probe in all cases. Iron incorporation into the SNs was confirmed by pathological examination.

Abstract
Oral squamous-cell carcinomas arise in mucosal linings of the oral cavity and frequently metastasise to regional lymph nodes in the neck. The presence of nodal metastases is a determinant of prognosis and clinical management. The neck is staged by palpation and imaging, but accuracy of these techniques to detect small metastases is low. In general, 30-40% of patients will have occult nodal disease and will develop clinically detectable lymph-node metastases when the neck is left untreated. The choice at present is either elective treatment or careful observation followed by treatment of the neck in patients who develop manifest metastases. These unsatisfying therapeutic options have been the subject of debate for decades. Recent developments in staging of the neck, including expression profiling and sentinel lymph-node biopsy, will allow more personalised management of the neck.

Abstract
OBJECTIVE Various lymphoscintigraphic imaging protocols exist for sentinel node (SN) identification in early-stage oral cancer. This study aimed to evaluate the clinical value of performing additional late lymphoscintigraphic imaging. METHODS We retrospectively analysed early (directly following injection of 99mTc-Nanocoll) and late (2-4 h after injection) imaging results of 60 early-stage (T1-T2, cN0) oral cancer patients scheduled for SN procedure. Lymphoscintigraphic results of late imaging were categorized into: (a) no visualization of additional hotspots considered to be SNs; (b) additional hotspots visualized that are considered to be SNs and (c) hotspots visualized only during late imaging. Histopathological results of the harvested SNs were related to the corresponding hotspot. RESULTS In all patients (n=60) lymphoscintigraphy was able to visualize a hotspot that was identified as an SN. In 51/60 (85%) patients, early imaging was able to visualize at least one hotspot, whereas in 9/60 (15%) patients, mostly with oral cavity tumours other than mobile tongue and floor-of-mouth tumours, only late imaging was able to visualize hotspots. In 14/51 (27%) patients, late imaging resulted in additionally visualized hotspots marked as SNs, resulting in a more extensive surgical procedure. These additionally removed SNs appeared to be of no clinical relevance, as all SNs identified during early imaging correctly predicted whether the neck was positive or negative for cancer. CONCLUSION Results of this study indicate that additional late lymphoscintigraphic imaging should be performed only in selected cases.

Abstract
This study aimed to evaluate the diagnostic reliability of sentinel lymph node biopsy in patients with squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx by reviewing the published literature. A systematic literature review was performed using MEDLINE from 1970 to 2011. With Boolean search strings, search terms included sentinel node, supraglottic, supraglottis, tongue, head and neck, oral, pharynx, laryngeal, and larynx. Additional studies were identified through article references. Duplicate data and articles were excluded based on treating institution and study inclusion time period. Additional studies were excluded if the head and neck subsite or tumor stage was not specifically identified or if the sentinel lymph node biopsy occurred in previously treated necks. All patients had sentinel lymph node biopsy performed followed by a concurrent neck dissection. Twenty-six studies met our inclusion criteria (n = 766 patients). The pooled sensitivity and negative predictive value of SLNB for all head and neck tumors was 95 % (95 % CI 91-99 %) and 96 % (95 %CI 94-99 %), respectively. The overall sensitivity and negative predictive value of SLNB in the subset of oral cavity tumors (n = 631) was 94 % (95 % CI 89-98 %) and 96 % (95 % CI 93-99 %), respectively. One-hundred percent of oropharyngeal (n = 72), hypopharyngeal (n = 5), and laryngeal (n = 58) tumor sentinel lymph biopsy results correlated with subsequent neck dissections giving a negative predictive value of 100 %, showing that, sentinel lymph node biopsy is a valid diagnostic technique to correctly stage regional metastases in patients with head and neck squamous cell carcinoma.
