Viral cardiovascular surgical diseases: global burdens, challenges and opportunities.

Globally, more than one billion people are vulnerable to neglected tropical diseases, many of which have viral origins and cardiovascular implications. Access to cardiovascular care is limited in countries where these conditions are endemic. Six billion people lack access to safe, timely and affordable cardiac surgical care, whereby over 100 countries and territories lack a single cardiac surgeon. Moreover, while clinically unique, the surgical consequences of neglected cardiovascular diseases with viral origins have been poorly described in the current literature. This review provides an overview of the global burden of viral cardiovascular disease, describes access to cardiac surgical care in regions where these conditions are endemic, and further highlights surgical consequences and considerations to manage patients requiring cardiac surgical care.

No-touch saphenous vein: current understanding of the conduit 'less handled'.

PURPOSE OF REVIEW: The no-touch technique is an established method to harvest the saphenous vein (NT-SV), which is the most commonly used conduit in coronary artery bypass grafting. Herein, we summarize the foundational evidence, as well as highlight recent innovations and ongoing clinical trials involving NT-SV. RECENT FINDINGS: Through preservation of perivascular tissue for atraumatic handling and omission of manual distension, the NT-SV maintains endothelial nitrous oxide synthase levels and experiences less vascular smooth muscle cell activation, which translates to slower progression of atherosclerosis and less size mismatch of the graft and target vessel. These biomolecular advantages allow NT-SV to provide superior graft patency compared to conventional skeletonized saphenous vein and approximating that of the radial artery. Nonetheless, the clinical benefits of NT-SV for mortality and reduction in major adverse cardiac and cerebrovascular events are insufficiently studied in the long-term. The drawback of NT-SV is the short-term harvest site complications, which may potentially be addressed by the advent of endoscopic no-touch technique. SUMMARY: NT-SV is a promising conduit, and its role will be further clarified in upcoming clinical trials and as follow-up lengthens. However, conduit selection and harvest technique should ultimately be personalized to the individual patient.

Combined ion beam irradiation platform and 3D fluorescence microscope for cellular cancer research.

To improve particle radiotherapy, we need a better understanding of the biology of radiation effects, particularly in heavy ion radiation therapy, where global responses are observed despite energy deposition in only a subset of cells. Here, we integrated a high-speed swept confocally-aligned planar excitation (SCAPE) microscope into a focused ion beam irradiation platform to allow real-time 3D structural and functional imaging of living biological samples during and after irradiation. We demonstrate dynamic imaging of the acute effects of irradiation on 3D cultures of U87 human glioblastoma cells, revealing characteristic changes in cellular movement and intracellular calcium signaling following ionizing irradiation.

Decision analysis in cardiac surgery: a scoping review and methodological primer.

OBJECTIVES: Randomized controlled trials are the gold standard for evidence generation in medicine but are limited by their real-world generalizability, resource needs, shorter follow-up durations and inability to be conducted for all clinical questions. Decision analysis (DA) models may simulate trials and observational studies by using existing data and evidence- and expert-informed assumptions and extend analyses over longer time horizons, different study populations and specific scenarios, helping to translate population outcomes to patient-specific clinical and economic outcomes. Here, we present a scoping review and methodological primer on DA for cardiac surgery research. METHODS: A scoping review was performed using the PubMed/MEDLINE, EMBASE and Web of Science databases for cardiac surgery DA studies published until December 2021. Articles were summarized descriptively to quantify trends and ascertain methodological consistency. RESULTS: A total of 184 articles were identified, among which Markov models (N = 92, 50.0%) were the most commonly used models. The most common outcomes were costs (N = 107, 58.2%), quality-adjusted life-years (N = 96, 52.2%) and incremental cost-effectiveness ratios (N = 89, 48.4%). Most (N = 165, 89.7%) articles applied sensitivity analyses, most frequently in the form of deterministic sensitivity analyses (N = 128, 69.6%). Reporting of guidelines to inform the model development and/or reporting was present in 22.3% of articles. CONCLUSION: DA methods are increasing but remain limited and highly variable in cardiac surgery. A methodological primer is presented and may provide researchers with the foundation to start with or improve DA, as well as provide readers and reviewers with the fundamental concepts to review DA studies.

Radiofrequency ablation as a treatment modality for primary hyperparathyroidism: a systematic literature review.

Background: Primary hyperparathyroidism (pHPT) is an endocrine disorder typically characterized by elevated serum calcium and elevated parathyroid hormone (PTH). While parathyroidectomy is the standard treatment, non-operative intervention such as radiofrequency ablation (RFA) has been adopted as an alternative for the management of pHPT, as it has been utilized in other endocrine glands such as thyroid and adrenal. In this literature review, we aim to evaluate the current practice of RFA for pHPT. Methods: A systematic literature search using PubMed, Web of Science, and Embase through June 2022 was conducted. Studies included in the review consisted of patient cohorts who had an unequivocal diagnosis of pHPT and underwent the treatment of pHPT with RFA. When more than one study was published from a similar cohort of patients, only the study with the most number of patients was considered. Studies included were assessed for bias using the critical appraisal instruments from the Joanna Briggs Institute (JBI) System. Results: A total of 14 studies describing 167 parathyroid glands treated in 163 patients were reviewed. The overall cure rate was 91.2%, with 5 patients undergoing more than one ablation. The most common adverse effect encountered was temporary dysphonia. Incomplete ablation and missed multiglandular disease were the most common reasons for RFA treatment failure. Conclusions: RFA may be an effective and safe alternative to parathyroidectomy in select patients with a well-localized, well-located parathyroid adenoma. Additional long-term data are needed to refine its role in the pHPT treatment algorithm.

Recommend with caution: A meta-analysis investigating papillary thyroid carcinoma tumor progression under active surveillance.

BACKGROUND: Papillary thyroid carcinoma (PTC) is an indolent disease with favorable outcomes. The non-surgical treatment approach known as active surveillance (AS) has been introduced as an alternative treatment instead of the traditional thyroidectomy. However, 10-15 % of PTC tend to progress. We sought to determine factors predicting the progression of PTC under AS. METHODS: A systematic search was performed in January 2022 using PubMed, Embase, Google Scholar, Web of Science, and ScienceDirect. PRISMA guidelines were used by multiple reviewers to extract study characteristics (author name, publication date, journal name, country, institution, and study design), as well as main outcomes and measures. A combination of utilization of thyroid replacement therapy, baseline tumor size and volume, follow-up tumor size and volume, and the presence of lymph node metastasis and its distribution, as well as surveillance duration, were the main measures of this study. RESULTS: Nine studies with 4166 patients were included, of which 354 showed tumor progression during AS (15 %; 95%CI = 7 % - 23 %). The average follow-up period was 41.58 months. The mean tumor maximum diameter was 8.54 mm (95%CI = 7.04-10.03). Tumor progression was most commonly secondary to an increase in volume by ≥50 % (75 %; 95%CI = 68 % - 80 %), then increase in diameter by ≥3 mm (41 %; 95%CI = 13 % - 76 %), and finally the development of lymph node metastasis (13 %; 95%CI = 9 % - 19 %). Approximately only 2 % of all patients thus developed new lymph node metastasis. Patient age, sex, and tumor size were not associated with higher risks of tumor progression. 12 % of AS patients eventually underwent surgery, though only 40 % (95%CI = 27 % - 53 %) of these patients displayed tumor progression. CONCLUSIONS: Our meta-analysis determined a tumor progression rate of 15 % in patients who underwent AS management, 13 % of which (2 % of all patients) developed lymph node metastasis. We found no protective or risk factors for tumor progression, and that almost half of all patients who underwent delayed surgery did so for reasons other than tumor progression. While not biopsying small (<1 cm) or very low suspicious nodules is already recommended, AS may be an appropriate treatment option in patients appropriately counseled, considering the low risk of advanced tumor progression but also the considerable patient population who fail to adhere to treatment. Alternatively, in aim of preventing overtreatment in patients who would rather take proactive measures against their low-risk carcinoma, minimally-invasive ablation techniques may be an attractive option.

Radiofrequency Ablation of Indeterminate Thyroid Nodules: The First North American Comparative Analysis.

Thyroid nodules can be classified as benign, malignant, or indeterminate, the latter of which make up 10-30% of nodules. Radiofrequency ablation (RFA) has become an attractive and promising therapy for the treatment of benign thyroid nodules. However, few studies have investigated the safety and efficacy of RFA for the management of indeterminate thyroid nodules. In this study, 178 patients with thyroid nodules diagnosed as benign (Bethesda II) or indeterminate (Bethesda III/IV) by preoperative cytopathological analysis were included. Patients in the benign and indeterminate cohorts had similar thyroid nodule volume reduction rates at 65.60% and 64.20%, respectively (p = 0.68). The two groups had similar nodular regrowth rates, at 11.2% for benign nodules and 9.40% for indeterminate nodules (p = 0.72). A total of three cases of transient dysphonia were reported. RFA of indeterminate thyroid nodules was comparable to that of benign thyroid nodules in all parameters of interest, including volume reduction rate. To our best knowledge, our work is the first North American analysis comparing benign and indeterminate thyroid nodules and suggests RFA to be a promising modality for the management of indeterminate thyroid nodules.

Predictive factors of radioiodine therapy failure in Graves' Disease: A meta-analysis.

BACKGROUND: I-131 therapy is a common treatment modality for adults with Graves' Disease (GD). Utilizing meta-analysis, we examined patient specific factors that predict I-131 therapy failure. METHODS: Literature search followed PRISMA. Comprehensive Meta-analysis (version 3.0) was used. Mantel-Haenszel test with accompanying risk ratio and confidence intervals evaluated categorical variables. Continuous data was analyzed using inverse variance testing yielding mean difference or standardized mean difference. Decision tree algorithms identified variables of high discriminative performance. RESULTS: 4822 collective patients across 18 studies were included. Male sex (RR = 1.23, 95%CI = 1.08-1.41, p = 0.002), I-131 therapy 6 months after GD diagnosis (RR = 2.10, 95%CI = 1.45-3.04, p < 0.001) and history of anti-thyroid drugs (RR = 2.05, 95%CI = 1.49-2.81, p < 0.001) increased the risk of I-131 therapy failure. Elevated free thyroxine, 24-h radioactive iodine uptake scan ≥60.26% and thyroid volume ≥35.77 mL were also associated with failure. CONCLUSION: Patient characteristics can predict the likelihood of I-131 therapy failure in GD. Definitive surgical treatment may be a reasonable option for those patients.

Presentation and outcomes of patients with undifferentiated thyroid carcinoma: a national perspective.

BACKGROUND: Undifferentiated thyroid cancer (UTC) accounts for only 1-2% of all thyroid cancers. UTC is one of the most aggressive solid tumors with high metastatic rates and mortality. The objectives of this study are to examine the characteristics of patients with UTC and their overall survival. METHODS: Retrospective analysis utilizing the National Cancer Database, 2004-2014 is performed. The study population included adults (≥18 years) patients with UTC or differentiated thyroid carcinoma (DTC), which served as a reference group. RESULTS: A total of 1,870 UTC and 209,707 DTC patients were identified. The median follow-up time of UTC patients was 3.9 months (interquartile range: 1.6-9.0 months). When compared to DTC patients, patients with UTC were more likely to be ≥45-year-old [OR: 48.62, 95% CI: (35.75, 66.14), P<0.001], male [OR: 2.02, 95% CI: (1.84, 2.22), P<0.001], and/or black [OR: 1.27, 95% CI: (1.08, 1.49), P=0.004]. UTC patients were more likely to have Medicaid/Medicare or no insurance and treated in low-volume hospitals (P<0.001). Overall survival in patients with UTC was lower in patients older than 65 years [OR: 1.63, 95% CI: (1.12, 2.38), P=0.011], with multiple comorbidities [OR: 1.65, 95% CI: (1.02, 2.67), P=0.040] and/or presented with metastatic disease [OR: 1.93, 95% CI: (1.71, 2.17), P<0.001]. Compared to thyroidectomy alone, patients without metastasis who received adjuvant radiotherapy and/or chemotherapy had a better overall survival (P<0.001 each). In patients with metastatic disease, any intervention or combination of interventions other than thyroidectomy alone improved survival (P<0.05). CONCLUSIONS: Older age, male, and/or black are associated with a higher prevalence of UTC compared to DTC. Although overall survival is poor in UTC, utilization of multi-modal treatment may improve survival.

Evaluation of YouTube videos as a patient education source for novel surgical techniques in thyroid surgery.

BACKGROUND: Patients and physicians are increasingly utilizing online video sharing sites such as YouTube for obtaining and disseminating health-related information in multimedia format; however, due to its free, open-access platform, YouTube videos fall short in providing validated, up-to-date medical information, and may even convey unintended messages to patients who are seeking additional information on surgeries. We evaluated the relevance, reliability, and quality of YouTube videos on novel surgical techniques in thyroid surgery. METHODS: The top 50 indexed YouTube videos for the queries, "robotic thyroid surgery" and "transoral thyroid surgery", were assessed by two independent reviewers for video quality and reliability for patient understanding. Videos were scored using Global Quality Score (GQS), a scale for video quality, and DISCERN Scoring, a questionnaire for reliability and quality measures of information presented. RESULTS: The mean ± standard deviation (SD) duration of the videos (n=50) was 8.1±3.7 minutes. Total views were 261,440 and the mean ± SD time since upload was 3.6±2.6 years. The median and interquartile range of video power index (VPI) was 1.9 (0.5-3.7), GQS was 3.0 (2.0-4.0), and DISCERN score was 2.8 (2.3-3.2). Most videos were uploaded by physicians (75.8%) and the highest number of videos (63.6%) uploaded were from the United States (US). Videos with higher quality and reliability scores were uploaded by academic professionals, and included videos of physicians who described procedural information, perioperative instructions, and possible postoperative complications (P<0.05). Adequate medical information on the procedure and discussion of complications in YouTube videos were independent predictors of advanced educational quality and reliability. CONCLUSIONS: Clinical information on new surgical techniques such as transoral and robotic thyroid surgeries in YouTube videos scored low on quality and reliability as a source of patient education. Physicians should provide supplemental educational material online and offline to aid patient understanding of novel procedures.

Evolution of IgA nephropathy in Singapore over four decades and a comparison of two cohorts from the first and fourth decade.

OBJECTIVE: In this study, we trace the changes in the clinical and histological pattern of IgA nephritis (IgAN) in Singapore as it has evolved over 4 decades and compare the clinical, demographic, histological, and renal outcome of patients with IgAN from the 1st decade and the 4th decade. MATERIALS AND METHODS: This is a retrospective study of all histologically proven IgAN diagnosed between 1976 and 2018. Clinical, laboratory, and histological characteristics between the 1st and the 4th decade, including treatment which could influence the disease progression and renal outcome of these two groups, were compared. We used the Oxford classification to compare the renal biopsy changes for these 2 decades as we were able to retrieve 125 renal biopsy tissues for the 1st cohort of IgAN studied in the 1970s for the comparative study. RESULTS: The commonest clinical presentation throughout the first 3 decades was asymptomatic hematuria and proteinuria (63, 52, and 49%, respectively). In the 4th decade, nephrotic syndrome (31%) was the commonest followed by asymptomatic hematuria and proteinuria (30%), hypertension (21%), and chronic renal failure (11%). The data showed that treatment can modify the Oxford MEST - Crescent scores. Renin-angiotensin system (RAS) blockers modified the S scores, immunosuppressants modified the T and C scores, and combination therapy with RAS blockers and immunosuppressants modified the E, S, and T scores. CONCLUSION: The Oxford MEST classification offers a robust and expressive classification for early and late disease progression with respect to the development of end-stage renal disease (ESRD). E and S seem to be indices of continuing disease activity with progressive glomerulosclerosis, probably still amenable to therapy, but T was a predictive indicator for those destined for ESRD and no longer amenable to therapy.

Impact of psychiatric comorbidities on outcomes related to thyroid and parathyroid operations.

BACKGROUND: We examined the effect of psychiatric comorbidities on perioperative surgical outcomes and the leading causes of readmissions in patients who underwent thyroid and parathyroid operations. METHOD: Patient information was retrieved from the Nationwide Readmission Database (2010-2017). Multivariate analysis was used to identify predictors for hospital readmissions. RESULTS: A total of 181,007 and 53,808 patients underwent thyroid and parathyroid operations, respectively. Of those, 8,468 (4.7%) and 6,112 (11.4%) patients were readmitted within 30 days. Psychiatric comorbidities were more frequent in readmitted cohorts after thyroidectomies (14.9% vs 10.4%; P < .001) and parathyroidectomies (16.8% vs 11.5%; P < .001), with anxiety being the most frequent cause (thyroid: 7.87%, parathyroid: 6.8%). Psychiatric comorbidities were associated with greater risk of in-hospital mortality (thyroid: odds ratio = 2.07, 95% confidence interval = 1.13-3.53; P = .015 and parathyroid: odds ratio = 1.67, 95% confidence interval = 1.04-2.70; P = .005), postoperative complications (thyroid: odds ratio = 1.528, 95% confidence interval = 1.473-1.585; P < .001 and parathyroid: odds ratio = 3.26, 95% confidence interval = 2.84-3.73; P < .001), prolonged duration of stay (thyroid: beta coefficient = 1.142, 95% confidence interval = 1.076-1.207; P < .001 and parathyroid: beta coefficient = 2.15, 95% confidence interval = 1.976-2.32; P < .001), and 30-day readmissions (thyroid: hazard ratio = 1.18, 95% confidence interval = 1.03-1.18; P = .047 and parathyroid: hazard ratio = 1.23, 95% confidence interval = 1.11-1.36; P < .001). Psychosis had the greatest risk of readmission (thyroid: hazard ratio = 1.51 and parathyroid: hazard ratio = 1.42), and dementia (odds ratio = 2.58) had the greatest risk of postoperative complications. CONCLUSION: Concomitant psychiatric conditions after thyroid and parathyroid operations were associated with increased risk of postoperative complications, prolonged hospital stays, and greater rates of readmissions.

Impact of surgery versus medical management on cardiovascular manifestations in Graves disease.

BACKGROUND: Graves disease is well known to have multiple adverse effects on the cardiovascular system. We compared the cardiovascular outcomes after surgical intervention versus medical treatment in patients with Graves disease. METHODS: We performed a retrospective study of all Graves disease patients with a cardiovascular comorbidity who underwent either surgical or medical management (N = 151). Perioperative biochemical and cardiovascular outcomes from the surgical versus the medical groups were analyzed. RESULTS: Of 151 patients, 69 (45.6%) patients underwent total thyroidectomy and 82 (54.3%) patients received medical treatment. Hypertension resolved in 44.7% of the patients from the surgical group vs 18% in the medical group (P = .03). Tachyarrhythmias, including atrial fibrillation and tachycardia, improved in 85.9% of patients in the surgical group vs 66% in the medical group (P = .01). All cardiovascular manifestations examined, hypertension, tachyarrhythmias, and heart failure, improved in 69% of patients in the surgical group and 42.6% of patients in the medical group during the follow-up period (P < .01). CONCLUSION: Surgical treatment offers a significant and rapid clinical improvement of cardiovascular manifestations in Graves disease patients, such as hypertension, tachyarrhythmias, and heart failure. Surgery should be considered and recommended in Graves disease patients with known cardiovascular manifestations.

Prevalence and Risk of Metastatic Thyroid Cancers and Management Outcomes: A National Perspective.

OBJECTIVES: Examine the prevalence and risk of metastasis in thyroid cancers and management outcomes. STUDY DESIGN: Retrospective analysis of the National Cancer Database, 2004-2014. METHODS: The study population included adult (≥ 18 years) patients with thyroid cancer. Analysis included multivariate logistic regression and Cox hazard ratio modeling. RESULTS: A total of 152,979 patients were included. Distant metastasis was reported in 1,867 (1.22%) patients. The distribution of metastatic cases based on pathology and tumor size were as follows in descending order: papillary thyroid carcinoma (PTC) 1 to 4 cm (30.53%), PTC > 4 cm (19.34%), undifferentiated (UTC) > 4 cm (14.14%), PTC < 1 cm (8.46%), follicular thyroid carcinoma (FTC) > 4 cm (7.28%), FTC 1 to 4 cm (5.52%), medullary thyroid cancer (MTC) ≤ 4 cm (3.96%), MTC > 4 cm (3.91%), UTC ≤ 4 cm (3.32%), Hürthle (HCC ) > 4 cm (2.09%), and HCC 1 to 4 cm (1.45%). Significant predictors of distant metastasis, while controlling for tumor pathology and size, included older age, male gender, non-White minorities, presence of multiple comorbidities, minimal, gross extrathyroidal extension (ETE), lymphovascular invasion (LVI), and concomitant central and lateral lymph node metastasis (LNM) (P < .05 each). The risk of distant metastasis in the absence of nodal metastasis, ETE, and LVI was highest for FTC > 4 cm. CONCLUSION: Although the risk of metastasis in well-differentiated thyroid carcinoma (WDTC) is low, the prevalence of metastatic thyroid cancer is highest in WDTC population because it is the most common type of thyroid cancer. Certain pathological features, including minimal ETE and central LNM, are associated with a higher prevalence of metastatic disease. LEVEL OF EVIDENCE: NA Laryngoscope, 131:237-244, 2021.

METASTATIC THYROID CANCER IN A MAN WITH TUMOR-FREE THYROID.

OBJECTIVE: The objective of this report is to emphasize the importance of considering thyroid cancer in the differential diagnosis, when the origin of a metastatic boney lesion is indeterminate. METHODS: Diagnostic studies performed included a thyroid function test, an ultrasound, and a computed tomography (CT) scan of the neck, biopsies of the bone, and thyroid lesions. RESULTS: A 61-year-old man was found to have incidental sclerotic bone lesions in the lumbar region on CT scan performed in the setting of a prostate abscess induced sepsis. The bone biopsy suggested metastatic follicular thyroid carcinoma. Imaging studies of the neck showed markedly enlarged left greater than right thyroid nodules. A surgical specimen from the staged total thyroidectomy showed no evidence of thyroid malignancy, despite a thorough review of microscopic tissue sections at 5 µm. A whole body scan 2-months after radioactive iodine therapy demonstrated persistent uptake in the metastatic lesion at L4 and interval progression of widely metastatic disease. CONCLUSION: Metastatic thyroid cancer may be present without a histopathologic evidence of thyroid malignancy, albeit rarely. When the origin of a metastatic boney lesion is unclear, thyroid cancer should be included in the differential diagnosis.

The Value of Renal Biopsy in Non-Insulin-Dependent Diabetes Mellitus in Singapore over the Past Two Decades.

OBJECTIVE: This study on the prevalence of diabetic nephropathy (DN) and coexistence of non-diabetic renal disease (NDRD) in a cohort of 255 non-insulin-dependent diabetes mellitus (NIDDM) patients aims to determine the value of performing renal biopsies in these patients and elucidate the factors which could affect their progression to end-stage renal disease (ESRD). METHODS: Among 255 NIDDM patients, 93 had DN alone, 69 had NDRD alone, and the remaining 93 had DN plus NDRD (mixed group). The indications for renal biopsy were based on clinical suspicion of superimposed NDRD, including heavy or rapidly increasing proteinuria, renal impairment even though diabetes is of relatively short duration, rapidly declining renal function, and presence of hematuria with dysmorphic red blood cells suggesting presence of glomerulonephritis. RESULTS: The following were predictors of ESRD: high systolic BP at biopsy, longer duration of diabetes, heavy proteinuria, and presence of diabetic retinopathy. Comparing patients in the NDRD group with the DN group and the mixed group, the NDRD group had lower serum creatinine and higher eGFR with lower urinary proteinuria and higher serum albumin at presentation and on follow-up. Kimmelstiel-Wilson nodules were associated with a poorer prognosis leading to a higher occurrence of ESRD among patients with DN. CONCLUSION: Renal biopsy is of value in indicating the prognosis of NIDDM patients with DN based on the diabetic lesions. For NIDDM patients with atypical course and suspicion of associated NDRD, a renal biopsy would enable us to diagnose the underlying NDRD and offer appropriate therapy. Most nephrologists would consider renal biopsy for an NIDDM patient based on clinical indications like atypical clinical course and suspicion of an associated NDRD, but they would not perform a routine renal biopsy like for a CKD patient, unless it is for a research indication.

Impact of Surgeon-Performed Ultrasound on Treatment of Thyroid Cancer Patients.

BACKGROUND: The 2015 American Thyroid Association Management Guidelines for patients with thyroid nodules recommended a comprehensive sonographic evaluation of thyroid nodules' characteristics and the presence of any suspicious cervical lymph nodes (LNs) in the central and lateral compartments. This detailed sonographic assessment is still not routinely performed. We hypothesized that an endocrine surgeon-performed ultrasound (SUS) significantly enhances the management of thyroid cancer patients when compared with referral ultrasound (RUS). METHODS: We conducted a retrospective review of 267 consecutive thyroid surgery patients who were diagnosed with thyroid cancer on final pathology. All patients had undergone a SUS, but only 130 cohorts with both RUS and SUS were included. Features of thyroid nodules and LN and changes in the management plan were recorded. RESULTS: Based on SUS assessment, 26 patients (20%) were noted to have suspicious thyroid nodules which warranted a fine-needle aspiration (FNA) and were missed in RUS. On FNA, there were 12 patients with Bethesda categories III/IV and 14 patients with Bethesda V/VI. Those 26 patients were found to have a malignancy in the final pathology assessment. Thirty-eight patients (29.2%) were noted to have suspicious central/lateral neck findings on SUS but were not reported in RUS. Additionally, 8 patients (6.1%) were found to have a parathyroid adenoma by SUS and required concurrent parathyroidectomy. DISCUSSION: A comprehensive neck ultrasound in thyroid cancer patients, performed by their endocrine surgeon, could enhance management planning and outcomes. This finding highlights the critical need for education and improvement of routine neck ultrasonographic examination performed in the community.
