Diagnostic adequacy and accuracy of surgeon-performed ultrasound guided fine needle aspiration in lateral neck masses.

BACKGROUND: Surgeon-performed ultrasound guided fine needle aspiration (SUS-FNA) reduces the time to diagnosis and treatment of head and neck pathology. Although it has been validated in the investigation of thyroid pathology, there is a paucity of evidence to support its use in lateral neck masses. This study aims to determine the accuracy and adequacy of SUS-FNA in the investigation of lateral neck masses. METHODS: A retrospective cohort analysis was performed of patients who underwent a SUS-FNA for lateral neck mass between June 2018 and October 2022 at a single institution. Pathologist reports were reviewed to determine the rate of FNA sample adequacy. A comparison was made between FNA cytology results and final histopathological diagnosis following surgical excision in a subset of patients to determine FNA accuracy. RESULTS: A total of 110 SUS-FNAs were performed on lateral neck masses. Diagnostic adequacy of SUS-FNA was determined to be 91% (100/110). When analysing the subset of patients who proceeded to surgical excision, the diagnostic accuracy of SUS-FNA was determined to be 88% (38/43). CONCLUSION: SUS-FNA results in high adequacy rates with good diagnostic accuracy in the investigation of lateral neck masses. This tool has great potential in reducing treatment delay in the management of head and neck cancer.

The negative predictive value of FDG PET/CT staging in early oropharyngeal squamous cell carcinoma and implications to transoral robotic surgery patient selection.

OBJECTIVES: Our objective was to determine the negative predictive value (NPV) of preoperative FDG PET/CTfor detecting locoregional nodal disease. The aim was to help inform the decision-making process when identifying patients with early-stage OPSCC that would be suitable for transoral robotic surgery (TORS) as a single-modality treatment. MATERIALS AND METHODS: A retrospective cohort study was conducted of adults with primary stage cT1-2 OPSCC with up to one metastatic neck lymph node (cN0-1) planned for TORS. Patients with a preoperative PET/CT and who had undergone staging neck dissection (ND) were included. Clinical and pathological nodal staging was established based on PET/CT and ND, respectively. The primary outcome was the frequency of occult (not seen on PET/CT) nodal disease on ND. RESULTS: Eighty-eight patients were included (N = 88). The rate of occult nodal disease was 28.4 % (n = 25). The NPV of PET/CT in the clinically negative neck was 79 % and 66 % in cases with a single clinical node. Following staging ND, thetreatment plan changed in 27 % of cases overall, 7 % in cN0 and 36.7 % in cN1. Among these, 18 % met criteria for radiotherapy and 9 % for CRT. This represented a decrease in the number of ideal candidates for TORS as single-modality treatment from 88 to 64 (73 %). CONCLUSIONS: PET/CT is a useful tool in the workup of patients for primary TORS. However, about one third of patients with early-stage OPSCC might benefit from adjuvant therapy not predicted by preoperative PET/CT. A staging ND helps confirm candidates for single-modality treatment with TORS.

Surgeon-performed ultrasound changes surgical management in patients with thyroid cancer.

BACKGROUND: A comprehensive neck ultrasound (US) is essential in the operative planning of patients with thyroid disease. Recent literature has shown surgeon-performed US (SUS) can be more accurate than radiology-performed US for the purpose of surgical planning. Missed findings on radiology-performed ultrasound may lead to inadequate surgical management. METHODS: A retrospective cohort study of patients undergoing total thyroidectomy with lateral neck dissection for thyroid cancer, with both radiology-performed US and SUS performed by a Head and Neck surgeon. Ultrasound findings and adherence to American Thyroid Association (ATA) guidelines were compared, and changes in management based on SUS findings were identified. RESULTS: A total of 26 patients who underwent total thyroidectomy with lateral neck dissection met the inclusion criteria. Preconsultation US investigations fulfilled criteria as recommended by the American Thyroid Association (ATA) guidelines in 57.7%% of cases. The central and lateral neck compartments were assessed in 57.7% and 84.6% of preconsultation US investigations respectively. Central and lateral metastatic neck metastases were incorrectly reported or not reported in 78.6% and 42.3% of cases. The SUS findings prompted a change in surgical management in 65.4% of cases. CONCLUSION: SUS changed surgical management in two thirds (65.4%) of patients. Reliance on radiology-performed ultrasound alone may result in incorrect staging. Awareness of the additional benefits of SUS is important for surgeons treating patients with thyroid disease to prevent inadequate surgery being performed.

Use of telemedicine consultations in head and neck cancer: patient perceptions, acceptability and accessibility.

BACKGROUNDS: Telemedicine has been effective in the management of various medical conditions, however, there is limited knowledge of its use in head and neck oncosurveillance. This is of importance currently while trying to mitigate the risk of transmission during the COVID-19 pandemic. This study aims to evaluate acceptability, satisfaction and perceptions of telemedicine technology among outpatients for head and neck oncologic surveillance. METHODS: A cross-sectional study was conducted for head and neck surgical oncology patients who attended telemedicine consultations between March and October 2020 at the Peter MacCallum Cancer Centre. Data on demographic, socioeconomic and acceptability variables was collected, utilizing Likert scale questions. The primary outcome measures were patient satisfaction and perceptions, while the secondary outcome was access to technology. RESULTS: One hundred and fifteen patients were invited to participate, and 100 were included in the final analysis; 95% of patient's had a positive experience with telemedicine appointments and were willing to have future telemedicine appointments. Regional and rural patients were more accepting of telemedicine consultations, citing savings in travel time and the minimal disruption to normal day-to-day activities. All participants had access to telecommunication devices, with 63% having three or more devices. Issues identified include a lack of physical examination by clinician for 65% of participants and the inability to self-examine for 88% of participants. CONCLUSION: The study demonstrates patients' acceptance of telemedicine appointments as a component of outpatient surveillance for head and neck surgical oncology. This has benefits during the COVID-19 pandemic in addition to increasing accessibility for rural patients.

Scoping review of head and neck neoplasms presenting with obstructive sleep apnoea: the importance of flexible nasendoscopy.

BACKGROUND: Obstructive sleep apnoea (OSA) can be caused by neoplasms involving the upper aerodigestive tract. Currently, many of these patients have this diagnosis missed, as most adults diagnosed with OSA do not undergo adequate head and neck examination including flexible nasendoscopy. We performed a review of the literature to shed light on this phenomenon and outline the pathologies and issues surrounding this sub-population of patients diagnosed with OSA. METHODS: A scoping review of the literature was conducted on head and neck neoplasms presenting with OSA. Data were extracted on demographics, clinical presentation, histopathology, treatment and patient outcomes. RESULTS: Sixty-seven articles were included, describing 79 patients. Mean age was 45.8 years, and 77.2% were male. Symptoms of OSA were present for an average of 29.2 months before a diagnosis of causative neoplasm was made. Forty-two different benign and malignant histopathological entities were reported. At diagnosis, the causative pathology of 100% of patients was visible on head and neck examination including flexible nasendoscopy, while only 53.2% were visible on trans-oral examination. One-third of patients had commenced inappropriate treatment for OSA, including three who had undergone sleep surgical procedures. The majority of patients were treated with surgery alone (72.2%). CONCLUSION: Although rare, neoplasms of the upper aerodigestive tract should be considered as a cause of OSA, especially in patients experiencing other symptoms in addition to the typical symptoms of OSA. They should particularly be considered in patients with comparatively lower body mass index or those with worsening OSA without an apparent cause identified.

Surgeon-performed ultrasound in a head and neck surgical oncology clinic: saving time and improving patient care.

INTRODUCTION: Surgeon-performed ultrasound (SUS) for head and neck masses is increasingly being performed by head and neck surgeons. This is the first study assessing its impact in a head and neck surgical oncology clinic, examining the effect on various parameters. METHODS: Retrospective analysis was conducted on a database, analysing and comparing all new patients reviewed 6 months prior to (pre-SUS group) and 6 months following (post-SUS group) the introduction of SUS to the outpatient head and neck surgical oncology clinic. The numbers of radiology imaging investigations (ordered through a medical imaging department), fine-needle aspirations (FNAs) performed, clinical appointments and time to definitive treatment decision were analysed and compared. RESULTS: A total of 365 patients were included: 169 in the pre-SUS group and 196 in the post-SUS group. There was a statistically significant difference in the number of total radiological imaging investigations performed (1.60 vs. 0.70, p < 0.00001), radiologist-performed FNAs (0.24 vs. 0.10, p = 0.0234), time for definitive treatment decision being made (16.4 days vs. 11.6 days, p = 0.04338), and number of clinical encounters (3.03 vs. 2.29, p < 0.00001). No statistically significant difference was observed in the number of head and neck surgical oncology clinic appointments (1.70 vs. 1.66, p = 0.6672). CONCLUSION: Surgeon-performed ultrasound reduces the number of radiological imaging investigations and FNAs performed, reduces time for definitive treatment decision being made, and reduces the number of clinical encounters for patients. This supports its use in head and neck cancer setting and has important implications for both patients and the health-care system.

Ultrasonido realizado por el otorrinolaringólogo-cirujano de cabeza y cuello: revisión de la literatura

Resumen El ultrasonido realizado por el otorrinolaringólogo-cirujano de cabeza y cuello permite realizar evaluaciones y diagnósticos en tiempo real, tomar decisiones en un menor tiempo y realizar intervenciones, lo que aumenta la eficiencia de una consulta. A pesar del profundo conocimiento de la anatomía de cabeza y cuello del otorrinolaringólogo, esta técnica aún no es muy difundida en nuestro país. Se recomienda la acreditación en un curso impartido por una entidad conocida y realizar una evaluación en informe estructurado. El ultrasonido realizado por el otorrinolaringólogo-cirujano de cabeza y cuello ha demostrado excelentes resultados para diferenciar masas cervicales benignas de aquellas malignas, y muy importantemente para tomar muestras de punción con agua fina o biopsias core. Se presenta una revisión de la literatura sobre el ultrasonido realizado por el cirujano, sus indicaciones, utilidad y recomendaciones al momento de realizarla.

Abstract Head and neck surgeon-performed ultrasound allows evaluations and diagnoses in real time, make faster decisions and carry out interventions, which increases the efficiency of the medical appointment. Despite otolaryngologists have a deep knowledge about head and neck anatomy, this technique is still not widespread in Chile. It is recommended to take an accreditation program given by a well-known entity and to perform structured evaluations and reports. Head and neck surgeon-performed ultrasound has shown excellent results to differentiate benign from certain malignant cervical masses, as well as to perform fine needle aspiration biopsies and core biopsies. We present a literature review on surgeon-performed ultrasound, its indications, efficacy and recommendations at the time of performing it.

Introduction of surgeon-performed ultrasound to a head and neck clinic: indications, diagnostic adequacy and a new clinic model?

BACKGROUND: Surgeon-performed ultrasound (SUS) changes management and surgical decision-making. It allows for immediate ultrasound-guided fine-needle aspiration (US-FNA) for the work-up of neck masses, lymph node metastases and thyroid nodules. We examined the introduction of SUS to an Australian Head and Neck cancer unit, identifying situations where it was used, and evaluated the diagnostic adequacy and accuracy of US-FNA. METHODS: A prospective database was created for all patients undergoing SUS and US-FNA, performed by two head and neck surgeons, between September 2018 and June 2019. The data were retrospectively analysed to identify when SUS was performed. Diagnostic adequacy and accuracy of US-FNA were determined after evaluating formal cytology and histopathology reports. RESULTS: A total of 183 diagnostic, surveillance and interventional SUS scans were performed for multiple indications. A total of 100 US-FNAs were performed on a number of different sites. Diagnostic adequacy and accuracy were 92% and 85%, respectively. CONCLUSION: After the introduction of SUS to our weekly routine head and neck cancer clinic, we identified multiple situations where it can be used successfully within our clinical landscape. Our diagnostic US-FNA results compared favourably to current literature, without additional need for clinic attendance by consultant radiologists or pathologists, saving valuable hospital resources. This introduction proposes a promising alternative to current neck lump clinic models.
