Objective: Sentinel node biopsy (SNB) is a surgical staging test in which sentinel nodes (SNs) undergo intensive histological analysis. SNB diagnoses early cancer spread, but can also reveal unexpected findings within the SNs. We review cases of incidental thyroid cells (TC) found in SNs from patients with oral squamous cell carcinoma (OSCC) to assess the prevalence of TC, and the clinical significance of these., Methods: Multicenter retrospective review of SNB performed for cT1-T2N0 OSCC. Incidental TC were identified by TTF-1 or thyroglobulin positivity. Anatomical location of nodes containing TC, TC morphology, and ongoing management/follow up of this incidental finding was recorded. Neck dissections performed during the same period were reviewed to establish the expected incidence of TC in neck nodes without serial sectioning analysis., Results: 278 SNB cases were reviewed. Ten procedures detected TC in nine patients (10/278, 3.6%). During the same time period 725 neck dissections were performed, six containing TCs (6/725, 0.8%). One patient underwent SNB twice with TC identified on both occasions. Three patients had both OSCC metastasis and thyroid cells. All SNB patients with TC identified underwent thyroid USS with no primary tumours identified. Three patients underwent thyroidectomy, in all cases no primary thyroid tumour was found., Conclusion: Prevalence of incidental TC in SNs appears to be higher than that reported in neck dissections, these are not likely to be clinically relevant and can be managed on a conservative basis in the absence of clear metastatic features., Level of Evidence: Multicentre retrospective cohort study, 3 Laryngoscope, 134:1278-1281, 2024., (© 2023 The Authors.

Introduction: Cutaneous squamous cell carcinoma (cSCC) is a frequent skin cancer with a high risk of recurrence characterized by tumor infiltration and, in advanced cases, a poor prognosis. ECT (electrochemotherapy) is an alternative treatment option for locally advanced or recurrent cSCC that is unsuitable for surgical resection. In this study, we aimed to evaluate the data in the InspECT (International Network for Sharing Practice on ECT) registry of the referral centers and to clarify the indications for the use of ECT as a treatment modality for cSCC., Materials and Methods: Patients with primary, recurrent or locally advanced cSCC from 18 European centers were included. They underwent at least one ECT session with bleomycin between February 2008 and November 2020, which was performed following the European Standard Operating Procedures., Results: The analysis included 162 patients (mean age of 80 years; median, 1 lesion/patient). Side effects were mainly local and mild (hyperpigmentation, 11%; ulceration, 11%; suppuration, 4%). The response to treatment per patient was 62% complete and 21% partial. In the multivariate model, intravenous drug administration and small tumor size showed a significant association with a positive outcome (objective response). One-year local progression-free survival was significantly better (p<0.001) in patients with primary tumors (80% (95% C.I. 70%-90%) than in patients with locally advanced disease (49% (95% C.I. 30%-68%)., Conclusion: In the present study, ECT showed antitumor activity and a favorable safety profile in patients with complex cSCC for whom there was no widely accepted standard of care. Better results were obtained in primary and small tumors (<3 cm) using intravenous bleomycin administration., Competing Interests: FT is an IGEA employer.

Background: Sentinel lymph node biopsy is an increasingly recognised option for accurate staging and subsequent management of the clinically negative neck in early stage oral cavity squamous cell carcinoma. However, the technique is currently underused due to several logistic constraints including increased burden on pathology services. Here, we describe the feasibility of an outsourced centralised pathology processing and reporting service for sentinel lymph node biopsies in oral cavity squamous cell carcinoma., Patients and Methods: The Southeast England Consortium comprises four surgical centres utilising a central pathology service. Consecutive cases between January 2016 and February 2020 were retrospectively evaluated for survival outcomes and laboratory turnaround times., Results: Twenty-eight per cent from a cohort of 139 patients had positive sentinel nodes. There was a trend towards greater overall, disease-free and disease-specific survival (OS, DFS and DSS, respectively) in sentinel node negative compared to sentinel node positive patients, but these differences were not statistically significant. The sensitivity, negative predictive value and false negative rate were 92.8%, 97.0% and 6.8%, respectively. The mean and mode laboratory TAT were 5 and 4 working days, respectively., Conclusion: An outsourced centralised pathology service is a feasible option to widen the availability of sentinel node biopsy in oral cavity squamous cell carcinoma., (© 2022 John Wiley & Sons A/S.

Facial transplants represent the current exemplar in the reconstruction of severely damaged faces, whereas conventional free flap reconstruction has its limitations in restoring both function and surface cover., Methods: In a retrospective study over 6 years (2014-2020), 5 cases (n = 5) of vascularized nerve flaps (VNFs) were performed by our team. These involved three acute and two late reconstructions. The mean age was 41 years with a maximum of 6-year follow-up. To objectify the different permutations and combinations, we categorized composite, chimeric, and hybrid VNFs into types I, IIa-c, and III, each with a unique characteristic. Postoperative function was evaluated using the validated Sunnybrook and Terzis scores for facial nerve palsy; masticatory function was assessed using dental impression studies., Results: There was a 100% flap survival rate, with no instances of flap necrosis and only one complication: hematoma at 24 hours postoperative. Sunnybrook and Terzis scores showed a statistically significant improvement postoperatively, indicating both improved repose and facial expressions (paired student t test, P < 0.05). Given that each VNF was specifically customized for a particular patient, each type of VNF in this cohort was unique, thereby illustrating each type succinctly., Conclusions: VNFs are separate entities from standard free flaps, as they require extensive preoperative planning to allow the deconstructing of composite blocks of tissue into separate vascularized entities and amalgamating them into a new conglomerate. This allows VNFs to fill a niche area in facial reconstructive surgery between face transplants and conventional free tissue transfers, with enormous potential., (Copyright © 2022 The Authors.
