One-stop thyroid nodule clinic with same-day fine-needle aspiration cytology improves efficiency of care

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.

Evaluation of a Clinical Pathway for Thyroid Nodular Disease: Timings and Delays in the Diagnosis and Treatment of Thyroid Cancer

Background: Due to the high prevalence of nodular thyroid disease in the general population and the need to rule out malignant tumours, a clinical pathway for nodular thyroid disease was created at our tertiary-level hospital. Our study aimed to quantify timings and delays in diagnosis and treatment in this clinical pathway, specifically for patients who were diagnosed with thyroid cancer. Methods: A retrospective review was conducted of patients who were newly diagnosed with thyroid cancer and who had been previously evaluated in the clinical pathway for nodular thyroid disease at our institution during 2015–2017. Patient demographics, previous diagnostic studies, cytological results, tumour details and key dates were analysed to identify wait times in diagnosis and treatment. Results: Forty patients with thyroid cancer were included. The diagnostic delay had a median time of 60 days, and the treatment delay was dependent on cytopathological results. The main cause for delay in the diagnostic phase was the timing of the thyroid ultrasound performed by the radiology department. In the treatment phase, patients with a cytological result of Bethesda III, V or VI underwent surgery at the suggested time, while those in the Bethesda II or IV category did not. Conclusions: The major delay found in the diagnostic phase was the timing of the thyroid ultrasound performed by the radiology department. We are not suggesting that this step must be eliminated, though the implementation of routine ultrasonography in a thyroid clinic can help identify patients who need more urgent evaluation for fine needle aspiration cytology. In our hospital, decision for surgery is based mainly on the cytopathological report. Imaging studies and/or molecular testing could be considered to reduce treatment delays.

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.

Radioactive iodine ablation post differentiated thyroid cancer surgery: an analysis of use and impact of the American Thyroid Association guidelines

BACKGROUND

The 2009 American Thyroid Association (ATA) three-tiered risk stratification, and its updated version in 2015, provided clearer guidance on the use of radioactive iodine (RAI) ablation in differentiated thyroid cancer (DTC) patients. This study examines the impact of these guidelines on RAI use in our institution.

METHODS

Patients diagnosed with DTC during three different time periods (group 1: 2002-2006, group 2: 2010-2014 and group 3: 2017-2018) were identified and risk stratified according to the ATA guidelines. RAI use and extent of surgery were compared between the three groups. Categorical variables were analysed using Fisher's exact (2 × 2) and chi-squared (>2 × 2) tests.

RESULTS

A total of 415 patients were included (group 1 = 88, group 2 = 215, group 3 = 112). The proportion of patients having total thyroidectomy were 84.6, 84.7 and 69.6% in groups 1, 2 and 3, respectively (P = 0.003). Central lymph node dissection was significantly higher in the more contemporary groups compared to group 1 (9.1 versus 41.9 versus 64.3%, P < 0.001). Overall, fewer patients received RAI in more recent times (76.6 versus 54.8 versus 26.8%, P < 0.001), most evident in the low-risk patients (70 versus 29.1 versus 5.1%, P < 0.001). In the high risk group, the majority received RAI, with no difference between the groups.

CONCLUSION

Comparing DTC patients treated in our unit before and after publications of the 2009 and 2015 ATA guidelines, more nodal surgery was performed with less RAI administered in the latter groups. Better risk stratification according to the ATA guidelines has allowed more judicious use of RAI ablation.
