Congenital Midline Cervical Cleft and Thyroglossal Duct Fibrous Cord-Like, is There a Mixed Presentation?

INTRODUCTION: Congenital midline cervical cleft is a rare condition and is frequently misdiagnosed as thyroglossal duct cyst. Otherwise, the combination of congenital midline cervical cleft and thyroglossal duct fibrosis in the same patient is as rare as important to be registered with the intention to inform and offer specific managements details for the literature. CASE PRESENTATION: Eight-year-old boy with simultaneous congenital midline cervical cleft and a thyroglossal duct fibrosis. The anatomic, clinical, radiologic, and pathologic characteristics of the congenital midline cervical cleft are described as well as surgical technique for removal and repair with Z-plasty. CONCLUSION: Congenital midline cervical cleft is a rare condition and when diagnosed must be surgically treated as early as possible. Its differential diagnosis is a clinical challenge.

Impact of the COVID-19 Pandemic on Brazilian Head and Neck Surgery Centers

Abstract Objective The outbreak of the COVID-19 pandemic had a considerable impact on the healthcare access, treatment, and follow-up of oncologic patients. The aim of this study was to evaluate how the COVID-19 pandemic has affected consultation and follow-up demand as well as treatment volume at Brazilian Head and Neck Surgery centers. Methods An anonymous online questionnaire was used for collection of data across all Brazilian Head and Neck Surgery Centers across a 3-month period (April‒June 2021). This information included the characteristics of each center, and the perceived self-reported impact of the COVID-19 pandemic on academic activities, residency training, and the diagnosis, treatment, and follow-up of patients with Head and Neck diseases between 2019 and 2020. Results The response rate across the 40 registered Brazilian Head and Neck Surgery Centers was 47.5% (n = 19). The data showed a significant reduction in the total number of consultations (24.8%) and number of attending patients (20.2%) between 2019 and 2020. The total number of diagnostic exams (31.6%) and surgical procedures (13.0%) conducted over this period also decreased significantly. Conclusions The COVID-19 pandemic had a significant national impact on Brazilian Head and Neck Surgery Centers. Future studies should examine the long-term effects of the pandemic on cancer treatment. Level of evidence Evidence from a single descriptive study.

Risk Factors for Malignancy in Patients with Multinodular Goiter

Abstract Introduction The identification of thyroid cancer may be conducted through clinical detection, imaging method, and histopathological examination. Both solitary nodules and multinodular goiter are associated with malignancy. Objective To assess the risk factors for malignancy among patients with multinodular goiter submitted to total thyroidectomy. Methods A series of 712 consecutive patients, submitted to total thyroidectomy between 2005 and 2016 with multinodular goiter regarding clinical, ultrasound, and pathological variables, was retrospectively evaluated. Results There were 408 cases of papillary carcinoma (57.3%), with the remaining being benign. Gender had no statistical significance (p = 0.169) for malignancy, unlike the Bethesda index, higher age group (p = 0.005), shorter clinical history time (p = 0.036), smaller number of nodules (p < 0.0001), and smaller nodule size (p < 0.0001), which were related to malignancy. Conclusion The Bethesda index, older age group, shorter clinical history, smaller number of nodules, and smaller size of nodule were related to the diagnosis of papillary carcinoma.

The impact of sentinel lymph node biopsy on the quality of life in patients with oral cavity squamous cell carcinoma / Impacto da biópsia do linfonodo sentinela na qualidade de vida em pacientes com carcinoma espinocelular da cavidade oral

Abstract Introduction Sentinel lymph node biopsy is a proven method for staging the neck in patients with early oral cavity squamous cell carcinoma because it results in less comorbidity than the traditional method of selective neck dissection, with the same oncological results. However, the real effect of that method on the quality of life of such patients remains unknown. Objective The present study aimed to evaluate the quality of life of patients with oral cavity squamous cell carcinoma T1/T2N0 submitted to sentinel lymph node biopsy compared to those that received selective neck dissection. Methods Cross-sectional study including 24 patients, after a 36 month follow-up, 15 of them submitted to the sentinel lymph node biopsy and 9 to selective neck dissection. All patients answered the University of Washington quality of life questionnaire. Results The evaluation of the questionnaires showed a late worsening of the domains appearance (p = 0.035) and chewing (p = 0.041), as well as a decrease of about 10% of general quality of life (p = 0.025) in patients undergoing selective neck dissection ​​in comparison to those undergoing sentinel lymph node biopsy. Conclusion Patients with early-stage oral cavity squamous cell carcinoma undergoing sentinel lymph node biopsy presented better late results of general quality of life, mainly regarding appearance and chewing, when compared to patients submitted to selective neck dissection.

Resumo Introdução A biópsia de linfonodo sentinela é um método comprovado para estadiamento cervical em pacientes com carcinoma espinocelular inicial da cavidade oral, porque apresenta menor taxa de morbidade do que o método tradicional de esvaziamento cervical seletivo, com os mesmos resultados oncológicos. Porém, o verdadeiro efeito desse método na qualidade de vida desses pacientes permanece desconhecido. Objetivo Avaliar a qualidade de vida de pacientes com carcinoma espinocelular de cavidade oral T1/T2N0 submetidos a biópsia do linfonodo sentinela em comparação aos pacientes nos quais o esvaziamento cervical seletivo foi feito. Método Estudo transversal que incluiu 24 pacientes, após 36 meses de seguimento, dos quais 15 foram submetidos a biópsia do linfonodo sentinela e nove a esvaziamento cervical seletivo. Todos os pacientes responderam ao questionário de qualidade de vida da University of Washington. Resultados A avaliação dos questionários evidenciou pioria tardia dos domínios aparência (p = 0,035) e mastigação (p = 0,041), bem como diminuição de cerca de 10% da qualidade de vida geral (p = 0,025) nos pacientes submetidos a esvaziamento cervical seletivo em comparação com aqueles submetidos a biópsia do linfonodo sentinela. Conclusão Pacientes com carcinoma espinocelular de cavidade oral em estágio inicial submetidos a biópsia do linfonodo sentinela apresentaram melhores resultados tardios de qualidade de vida geral, principalmente quanto à aparência e à mastigação, quando comparados aos pacientes submetidos a esvaziamento cervical seletivo.

Association between Thyroiditis and Multifocality in Papillary Thyroid Carcinoma.

Introduction Hashimoto thyroiditis (HT) shares many characteristics with papillary thyroid carcinoma (PTC), and some studies show that, when associated, PTC is diagnosed mostly with smaller lesions and multifocal pattern. Objective To evaluate the relationship between HT and PTC. Methods A retrospective study of 155 patients who underwent total thyroidectomy from 2009 to 2015. Demographical, clinical and ultrasonographical data, as well as anatomopathological findings were evaluated. Results There were signs of thyroidits in 35 patients, and 114 patients had a unifocal disease. There was no statistical significance between the variables studied and thyroiditis. However, when compared with the occurrence of unifocal or multifocal lesions, there was statistical significance regarding age ( p = 0.038) and mass ( p = 0.031). There was no direct relationship between thyroiditis and multifocality ( p = 0.325) nor between thyroiditis and cervical extension of the disease ( p = 0.300 e p = 0.434). Conclusion There was no relationship between thyroiditis and multifocality in cases of PTC.

Oral Squamous Cell Carcinoma Bone Invasion: Possible Roles of E-Cadherin in Osteoclastogenesis and Bone Infiltration.

INTRODUCTION: Squamous cell carcinoma is the most common cancer of the oral cavity. When the tumor invades the bone tissue, the prognostic and survival rates decrease a lot, and the treatment becomes more aggressive, with several damages to the patient and health system. Many of the molecular mechanisms of bone invasion process are not understood yet, but it is already known that one of central processes of tumor evolution - adjacent tissues invasion and metastasis - is a large spectrum of phenotypic changes in epithelial cells to mesenchymal, in a process named as epithelial-mesenchymal transition (EMT). Loss of E-cadherin, an important epithelial cell adhesion protein, is a hallmark of this phenomenon. The objective of this retrospective study is to evaluate the expression of E-cadherin protein, comparing its distribution with clinical characteristics of the patients and possibly relation to EMT. METHODS: Sixty-two cases with respective clinical data were analyzed by comparing immunohistochemical, H and E staining, and clinical data, observing the tumor-bone interface (TBI) and the surrounding tumor that had no direct contact with the bone surface (ST). RESULTS: Forty cases were positive for E-cadherin (64%) with a heterogeneous pattern. Statistical analysis showed a significant difference between the presence of E-cadherin expression and tobacco smokers. Also, the equal or weaker protein expression in the ST than TBI is related to a worse overall survival. No statistically significant difference in other prognostic factors was observed. CONCLUSION: Our results suggest that the tumor cells that interact with the bone tissue could gain molecular changes, like partial EMT and osteoclastogenesis induction, which facilitate their migration and increase the bone resorption, resulting in a worse patient's prognosis.

Neck recurrence in papillary thyroid carcinoma.

INTRODUCTION: papillary thyroid carcinoma is a tumor with good prognosis. However, some patients treated present neck recurrence. OBJECTIVE: to evaluate the risk factors for neck recurrence. METHODS: a retrospective study enrolled 89 patients (68 women and 21 men) diagnosed with papillary carcinoma who underwent total thyroidectomy. In 21 patients, neck dissection was performed and 62 patients underwent radioiodinetherapy. Twelve patients relapsed with metastasis in this period with an average of 3.6 years. RESULTS: out of 89 patients, 76.4% were female. Relapse occurred in nine (13.23%) women and three (14.28%) men. The average age of the patients was 44 years in the control group and in patients with relapsed. Eighteen patients (23.37%) in the control group and eight (64.28%) who relapsed had positive lymph nodes at initial diagnosis. The tumor size was significantly larger in the group of patients with cervical recurrence (3.3cm vs. 1.6cm - p=0.008, Student t test), whereas the presence of metastatic lymph nodes at the moment of the first operation was also significant (p=0.004 -Fisher exact test). The tumor size was an independent risk factor for recurrence at the multivariate anaylsis (OR=2.4, IC95%:1.3-4.6 - p=0,007, logistic regression). CONCLUSION: there is an increase in the risk of lymph node recurrence during the follow up of 2.4 folds for each increase of 1cm in the longer nodule diameter.

RESUMO Introdução: o carcinoma papilífero da tireoide é um tumor com bom prognóstico. Entretanto, alguns pacientes tratados evoluem com recidiva cervical. Objetivo: avaliar os fatores de risco para recidiva cervical. Métodos: um estudo retrospectivo arrolou 89 pacientes (68 mulheres e 21 homens) diagnosticados com carcinoma papilífero, submetidos à tireoidectomia total. Em 21 pacientes, realizou esvaziamento cervical e, em 62, radioiodoterapia. Doze pacientes apresentaram recorrência linfonodal no período, com media de 3,6 anos. Resultados: dos 89 pacientes, 76,4% eram mulheres. A falha ocorreu em nove mulheres (13,23%) e três homens (14,28%). A média etária tanto dos pacientes recidivados como do grupo-controle foi de 44 anos. Dezoito pacientes (23,37%) no grupo-controle e oito (64,28%) dentre os que recidivaram tinham linfonodos positivos ao diagnóstico inicial. O tamanho tumoral foi significativamente maior no grupo de pacientes que apresentaram recidiva cervical (3,3 cm vs. 1,6cm - p=0,008, teste t de Student), o mesmo foi observado para a presença de linfonodos metastáticos quando da primeira cirurgia (p=0,004 - teste exato de Fisher). À análise multivariada, o tamanho tumoral foi fator de risco independente de recidiva (OR=2,4, IC95%:1,3-4,6 - p=0,007, regressão logística. Conclusão: para cada aumento de 1cm no maior diâmetro da lesão, há um aumento de 2,4 vezes no risco de recidiva linfonodal ao longo do acompanhamento.

Recurrence of laryngeal squamous cell carcinoma in patients undergoing organ preservation therapy: are there symptoms associated with recurrence?

Introduction: The larynx is a organ of the upper aerodigestive tract that plays an essential role in protecting the airways during swallowing. Squamous cell carcinoma is the most common malignant neoplasm affecting this region and early diagnosis has an important role in treatment outcome. Objectives: This study aims to evaluate whether patients with hypopharyngeal and/or laryngeal squamous cell carcinoma (SCC) who underwent organ preservation therapy (OPT) present at the time of relapse some factor that determines the local recurrence of the disease. Methods: Patients submitted to OPT were selected at the Cancer Institute of the State of São Paulo (ICESP), at the end of treatment, from January 2012 to December 2017. We collected retrospective data on demographics, clinical staging, location of the primary tumor, presence or absence of recurrence, weight and percentage of weight loss at different moments, alimentary pathway and symptomatology at the time of relapse. Results: The absence of symptoms was associated with the absence of relapse (p <0.001). Fully oral diet at the last visit was a significant factor for the absence of relapse (p = 0.005). The weight comparison of all the patients before the beginning of OPT and after the end of the treatment, showed an average drop of 3.4 kg. In the group-separated analysis, patients who did not recur showed an average loss of 0.7%. Patients with relapse, showed a loss of 2.0% of the weight at the time of relapse. Conclusion: Weight loss and the presence of symptoms were important predictors of recurrence with statistical significance. These factors may help to better manage these patients, with earlier investigations and, therefore, the possibility of rescue treatments with a shorter duration.

Effectiveness of harmonic scalpel in patients submitted to total thyroidectomy: systematic review with meta-analysis.

OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of the harmonic scalpel compared to the conventional technique in patients submitted to total thyroidectomy. METHOD: This is a systematic review with inclusion of randomized controlled trials (RCTs) that compared both techniques. An electronic search was carried out in the Medline and Lilacs databases until June 2017. The outcomes analysed were operation time, intraoperative bleeding, surgical morbidity, and costs. RESULTS: Data from 31 primary studies were included. The use of the harmonic scalpel correlates to a shorter operation time (p <0.001) and a lower volume of intraoperative bleeding (p <0.001). There were no differences in the risk of transient (p = 0.53) and permanent (p = 0.70) hypocalcaemia, transient (p = 0.61) and permanent (p = 0.50) dysfunctions of the inferior laryngeal nerve and hematoma (p = 0.14). CONCLUSION: Total thyroidectomy using a harmonic scalpel is effective and safe compared to the conventional technique.

Substernal goiter and laryngopharyngeal reflux

ABSTRACT Objective This study aims to compare the prevalence of laryngopharyngeal reflux signs between two groups of patients undergoing thyroidectomy for voluminous goiter: substernal goiters and voluminous cervical goiter without thoracic extension. Subjects and methods A retrospective case-control study was performed with data retrieved of the charts of the patients submitted to thyroidectomies occurred at a tertiary care center (Head and Neck Surgery Department, University of São Paulo Medical School) between 2010 and 2014. The selected thyroidectomies were allocated in two groups for study: patients with substernal goiters and patients with voluminous cervical goiter without thoracic extension. Cervical goiters were selected by ultrasonography mensuration. Clinical criterion was used to define substernal goiter. Results The average thyroid volume in patients with substernal goiter was significantly greater than the average volume in patients with only cervical goiter (p < 0.001). The prevalence of signs of reflux laryngitis at laryngoscopy was significantly greater in substernal goiter patients (p = 0.036). Moreover, substernal goiter was considered as the unique independent variable for high reflux laryngitis signs at laryngoscopy (OR = 2.75; CI95%: 1.05-7.20; p = 0.039) when compared to only cervical goiter patients. Conclusion This study shows a significant association between substernal goiters and signs of laryngopharyngeal reflux at preoperative laryngoscopy. Therefore, when compared with voluminous cervical goiters, the substernal goiters increase the chance of reflux laryngitis signs in patients.

Biometric measurements involving the terminal portion of the thoracic duct on left cervical level IV: an anatomic study.

To determine the point of entrance of the thoracic duct in the venous system, as well as to evaluate some biometric measurements concerning its terminal portion, we conducted an anatomic study on 25 non-preserved cadavers. The termination of the thoracic duct occurred on the confluence between the left internal jugular vein and the left subclavian vein in 60 % of the individuals. The average results for the biometric measurements were: distance between the end of left internal jugular vein and omohyoid muscle 31.2 ± 2.7 mm; distance between the end of thoracic duct and the left internal jugular vein 0.0 ± 0.0 mm; distance between the end of thoracic duct and the left subclavian vein 3.6 ± 1.0 mm; distance between the end of thoracic duct and the left brachiocephalic vein 10.7 ± 3.1 mm. Moreover, it was identified that the left internal jugular vein length in level IV, measured between its entrance in the left subclavian vein and the omohyoid muscle, was able to predict the termination of the thoracic duct on the junction between the left internal jugular vein and the left subclavian vein (OR = 2.99) with high accuracy (79.3 %). In addition, the left internal jugular vein length at level IV was able to predict the localization of thoracic duct termination. Thus, this finding has practical value in minimizing the risk for a potential chyle leak during or after a left-sided neck dissection.

Adjuvant treatment delay in breast cancer patients.

BACKGROUND: to evaluate if time between surgery and the first adjuvant treatment (chemotherapy, radiotherapy or hormone therapy) in patients with breast cancer is a risk factor for lower overall survival (OS). METHOD: data from a five-year retrospective cohort study of all women diagnosed with invasive breast cancer at an academic oncology service were collected and analyzed. RESULTS: three hundred forty-eight consecutive women were included. Time between surgery and the first adjuvant treatment was a risk factor for shorter overall survival (HR=1.3, 95CI 1.06-1.71, p=0.015), along with negative estrogen receptor, the presence of lymphovascular invasion and greater tumor size. A delay longer than 4 months between surgery and the first adjuvant treatment was also associated with shorter overall survival (cumulative survival of 80.9% for delays ≤ 4 months vs. 72.6% for delays > 4 months; p=0.041, log rank test). CONCLUSION: each month of delay between surgery and the first adjuvant treatment in women with invasive breast cancer increases the risk of death in 1.3-fold, and this effect is independent of all other well-established risk factors. Based on these results, we recommend further public strategies to decrease this interval.

Applicability of modified Glasgow Prognostic Score in the assessment of elderly patients with cancer: A pilot study.

OBJECTIVES: To evaluate the relationship between inflammatory parameters through the modified Glasgow Prognostic Score (mGPS) and other clinical characteristics of elderly patients with cancer, including frailty evaluated by the Edmonton Frailty Scale (EFS). MATERIALS AND METHODS: We included patients from the oncology service at Faculdade de Medicina do ABC with a confirmed diagnosis of solid tumor aged 65 years or more at diagnosis. Patients were assessed by applying the translated and validated to Portuguese version of the EFS and also had blood sample collection for the evaluation of C-reactive protein (CRP) and albumin for calculation of the mGPS. RESULTS: We included 52 patients of both sexes, with median age of 72.5 years, of these 67.3% had localized disease and 32.7% metastatic disease. The mGPS presented 17.3% of high-risk patients. The frailty evaluated by EFS occurred in 57.6% of patients. Patients with both abnormal parameters (CRP and albumin) in the mGPS had significantly higher scores on EFS when compared to those with no change (6 vs. 9.56 points, p=0.021). The mGPS correlated also with clinical staging (p=0.019) and performance status (p=0.039). CONCLUSIONS: Inflammatory parameters correlate significantly with frailty, more advanced clinical stage and poor functional status.

Postoperative calcium levels as a diagnostic measure for hypoparathyroidism after total thyroidectomy

ObjectiveThe aim of the present study was to identify a fast, efficient and low-cost method to diagnose hypoparathyroidism after total thyroidectomy.Materials and methodsOne hundred and forty medical records, which contained patients’ clinical and laboratory data, were retrospectively analyzed. Patient parathyroid hormone values, which were obtained immediately following operation, were compared with their ionized calcium levels the morning after surgery. This comparison was used to examine the correlation between the two variables in predicting hypoparathyroidism because measuring calcium levels is low-cost and more available in the hospitals compared to measuring parathormone (PTH) levels.ResultsThere was a positive and statistically significant correlation between PTH and ionized calcium values (Pearson correlation coefficient, r = 0.456; p < 0.0001). The values of first postoperative day ionized calcium levels (stratified by the 1.10 mmol/l cut-off value) were tested as a diagnostic measure for hypoparathyroidism, and a PTH < 15 pg/mL obtained immediately following operation served as a reference. This analysis showed that ionized calcium levels measured on the first postoperative day had a sensitivity of 45.6% (95% CI 30.9-61.0%), a specificity of 88.9% (95% CI 80.5-94.5%) and an accuracy of 76.7% (95% CI 68.7-83.5%) as a diagnostic measure for hypoparathyroidism.ConclusionIn conclusion, we demonstrated that patients who had high ionized calcium levels on the first postoperative day also had high PTH levels immediately following operation and, therefore, they had lower rates of hypoparathyroidism.
