ABSTRACT

Abstract Objective: To investigate the prognostic factors to developing parotid and neck metastasis in locally advanced and relapsed Cutaneous Squamous Cell Carcinoma (CSCC) of the head and neck region. Methods: Single-center retrospective cohort study enrolling consecutive patients with advanced CSCC from 2009 to 2019. Seventy-four cases were identified. Study variables demographic data, clinical skin tumor stage, neck stage, parotid stage (P stage), surgical treatment features, and parotid, regional, and distant metastases. Survival measures: Overall Survival (OS) and Disease-Specific Survival (DSS). Results: The study group included 72.9% men (median age, 67 years); 67.5% showed T2/T3 tumors, 90.5% comorbidities, 20.2% immunosuppressed, with median follow-up: 35.8 months. The most frequent skin primary were auricular and eyelid regions, 75% underwent primary resection with flap reconstruction. Parotid metastasis was present in 50%, 32.4% showing parotid extracapsular spread, multivariate analysis found OR = 37.6 of positive parotid metastasis evolving into positive neck metastasis, p = 0.001. Occult neck metastasis, neck metastasis, and neck extracapsular spread were observed in 13.5%, 51.3%, and 37.8%, respectively. Kaplan-Meier survival: Clinical T4 versus T1, p = 0.028, P1 stage: 30% and 5% survival at 5 and 10 years, P3 stage: 0%, p = 0.016; OS and DSS showed negative survival for the parotid metastasis group, p = 0.0283. Conclusion: Our outcomes support a surgically aggressive approach for locally advanced and relapsed CSCC, with partial parotidectomy for P0, total parotidectomy for P1-3, selective I-III neck dissection for all patients and adjuvant radiochemotherapy to appropriately treat these patients with advanced CSCC of the head and neck region. Level of evidence: II b - Retrospective Cohort Study - Oxford Centre for Evidence-Based Medicine (OCEBM).

ABSTRACT

Abstract Objective: Goiters and benign nodules detected in the thyroid are growing lesions and the COVID-19 pandemic have negatively impacted on their surgical treatment. The appropriate selection of patients to treatment will improve the overall health status. This article review will focus on the impact of the COVID-19 pandemic on treatment of benign conditions of the thyroid gland and their implications. Methods: This review pointed out the status of the health system in developing country and the problems to treat benign surgical diseases of thyroid. Aspects of epidemiology, incidence, clinical presentation and surgical treatment of goiters, economic and health status impact were cited. Results: All surgical treatment of goiter and other benign conditions were postponed, forced to redirect, and reschedule all benign surgeries, situation aggravated by poor public management and closure of hospital beds. These conditions have caused deterioration in patients' physical (decompensated thyroid disease) and mental health status, increasing work disabilities and burdening society by increasing the social and health cost. The overall situation could be catastrophic in emergent countries where this increased disease-related social expenditure on surgical treatment may increase the risk of national impoverishment as increase the treatment cost. Brazilian Society Head and Neck Surgery related some recommendations and new suggestions were made to safely treat these high potential hazard surgical conditions. Conclusions: Surgeries for goiter and benign thyroid conditions can be performed during the COVID-19 pandemic, following strict safety protocols for the patient and the medical team, reducing the negative economic and on patient health impact.


Resumo Objetivo: Bócios e nódulos benignos detectados na tireoide são lesões em crescimento e a pandemia de Covid-19 impactou negativamente seu tratamento cirúrgico. A seleção adequada de pacientes para o tratamento vai melhorar o estado geral de saúde. Esta revisão de artigos se concentrará no impacto da pandemia de Covid-19 no tratamento de condições benignas da glândula tireoide e suas implicações. Método: Esta revisão evidenciou a situação do sistema de saúde em países em desenvolvimento e os problemas para tratar doenças cirúrgicas benignas da tireoide. Aspectos da epidemiologia, incidência, apresentação clínica e tratamento cirúrgico do bócio, impacto econômico e no estado de saúde foram relatados. Resultados: Todos os tratamentos cirúrgicos de bócio e outras condições benignas foram adiados, forçados a se redirecionar e a remarcar todas as cirurgias benignas, situação agravada pela má gestão pública e fechamento de leitos hospitalares. Essas condições têm causado deterioração do estado de saúde física (doença da tireoide descompensada) e mental dos pacientes, aumentam as incapacidades para o trabalho e sobrecarregando a sociedade e o custo social e de saúde. A situação geral pode ser catastrófica em países emergentes, onde esse aumento dos gastos sociais relacionados à doença sob tratamento cirúrgico pode aumentar o risco de empobrecimento nacional à medida que aumenta o custo do tratamento. A Sociedade Brasileira de Cirurgia de Cabeça e Pescoço forneceu algumas recomendações e novas sugestões foram feitas para tratar com segurança essas condições cirúrgicas de alto risco potencial. Conclusão: As cirurgias para bócio e condições benignas da tireoide podem ser feitas durante a pandemia de Covid-19, se forem seguidos rigorosos protocolos de segurança para o paciente e equipe médica, o que reduz o impacto negativo na economia e na saúde do paciente.

ABSTRACT

BACKGROUND: The diagnosis of cancer in Bethesda III/IV thyroid nodules is challenging as fine-needle aspiration (FNA) has limitations, and these cases usually require diagnostic surgery. As approximately 77% of these nodules are not malignant, a diagnostic test accurately identifying benign thyroid nodules can reduce "potentially unnecessary" surgery rates. We have previously reported the development and validation of a microRNA-based thyroid classifier (mir-THYpe) with high sensitivity and specificity, which could be performed directly from FNA smear slides. We sought to evaluate the performance of this test in real-world clinical routine to support clinical decisions and to reduce surgery rates. METHODS: We designed a real-world, prospective, multicentre study. Molecular tests were performed with FNA samples prepared at 128 cytopathology laboratories. Patients were followed-up from March 2018 until surgery or until March 2020 (patients with no indication for surgery). The final diagnosis of thyroid tissue samples was retrieved from postsurgical anatomopathological reports. FINDINGS: A total of 435 patients (440 nodules) classified as Bethesda III/IV were followed-up. The rate of avoided surgeries was 52·5% for all surgeries and 74·6% for "potentially unnecessary" surgeries. The test achieved 89·3% sensitivity, 81·65% specificity, 66·2% positive predictive value, and 95% negative predictive value. The test supported 92·3% of clinical decisions. INTERPRETATION: The reported data demonstrate that the use of the microRNA-based classifier in the real-world can reduce the rate of thyroid surgeries with robust performance and support clinical decision-making. FUNDING: The São Paulo Research-Foundation (FAPESP) and Onkos.

ABSTRACT

BACKGROUND: The symptomatic (swelling and pain) salivary gland obstructions are caused by sialolithiasis and salivary duct stenosis, negatively affecting quality of life (QOL), with almost all candidates for clinical measures and minimally invasive sialendoscopy. The impact of sialendoscopy treatment on the QOL has been little addressed nowadays. The objective is to prospectively evaluate the impact of sialendoscopy on the quality of life of patients undergoing sialendoscopy due to benign salivary obstructive diseases, measured through QOL questionnaires of xerostomia degree, the oral health impact profile and post sialendoscopy satisfaction questionnaires. RESULT: 37 sialendoscopies were included, most young female; there were 64.5% sialolithiasis and 35.4% post-radioiodine; with 4.5 times/week painful swelling symptoms and 23.5 months symptom duration. The pre- and post-sialendoscopy VAS values were: 7.42 to 1.29 (p < 0.001); 86.5% and 89.2% were subjected to sialendoscopy alone and endoscopic dilatation respectively; 80.6% reported improved symptoms after sialendoscopy in the sialolithiasis clinic (p < 0.001). The physical pain and psychological discomfort domain scores were mostly impacted where sialendoscopy provided relief and improvement (p < 0.001). We found a positive correlation between sialendoscopy and obstructive stone disease (p < 0.001) and no correlation in sialendoscopy satisfaction in xerostomia patients (p = 0.009). CONCLUSIONS: We found improved symptoms with overall good satisfaction after sialendoscopy correlated with stones; and a negative correlation between xerostomia. Our findings support the evident indication of sialendoscopy for obstructive sialolithiasis with a positive impact on QOL and probably a relative time-dependent indication for stenosis/other xerostomia causes that little improved QOL satisfaction. LEVEL OF EVIDENCE: 2b-Prospective non-randomized study. TRIAL REGISTRATION: WHO Universal Trial Number (UTN): U1111-1247-7028; Brazilian Clinical Trials Registry (ReBeC): RBR-6p8zfs.

ABSTRACT

Mucoepidermoid carcinomas (MECs) are a form of salivary gland malignancy. They are classified according to histological grade and perineural invasion (PNI). In another cancer subtypes, positive-PNI suggests increased poor prognosis; however, the role of isolated positive-PNI salivary gland MEC can still be better investigated as a risk factor. This study investigated whether isolated PNI is independently associated with poor outcomes. Retrospective study, cohort case-series, single-center hospital from 2009 to 2019. Patient demographics, primary tumor, intervention, and survival data are included. Univariate, multivariate, and Kaplan-Meier survival curve analyses were used for comparison.The study group consisted of 32 patients (15 PNI-positive tumors, and 17 PNI-negative tumors), all admitted for surgery. Univariate analysis showed differences in grade (p = 0.038), positive margins (p = 0.034), soft tissue invasion (p < 0.001), pathological stage (p = 0.014), recurrence (p = 0.015), distant metastasis (p = 0.015) and MEC related death (p = 0.015). The risk in PNI-positive patients to develop soft tissue invasion and positive surgical margins was OR = 8.57 and OR = 4.88, respectively. Multivariate analysis found age differences (p = 0.038), with OR = 1.08. The Disease Specific Survival (DSS) was worst in the PNI-positive group (log-rank p-value = 0.0011), where the probability of dying occurred in the 12-24 months period (log-rank p-value = 0.002). PNI-positive salivary gland MEC is an independent prognostic factor, with poor DSS, increased locoregional recurrence, close correlation with a more aggressive pattern of the disease, and should be reviewed as a high grade histological criteria. Our findings may imply changes in the clinical approach with a more aggressive attitude in the overall treatment.

ABSTRACT

Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course.


As neoplasias das glândulas salivares são relativamente raras, compreendendo cerca de 1% das neoplasias de todo corpo, com incidência de 1/100.000 habitantes por ano. As neoplasias benignas predominam sobre as malignas. O prognóstico depende muito do tipo histológico, grau de diferenciação, localização, infiltração de tecidos vizinhos e da presença de metástases regionais ou a distância. O principal tratamento ainda é a cirurgia, com os seus desafios e dificuldades, devido aos ramos do nervo facial nas glândulas salivares maiores, seguido de radioterapia e em casos selecionados quimioterapia adjuvante. O objetivo desta revisão é fornecer ao leitor uma abordagem histórica sobre o tratamento das doenças das glândulas salivares, com especial atenção às doenças da glândula parótida assim como peculiaridades associadas aqueles que as estudaram ao longo da história.

ABSTRACT

PURPOSE The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to facilitate visualization and dissection in order to prevent injuries. METHODS Forty adult male Wistar rats were submitted to facial injection of saline solution (Gsf-control group, 10) or fluorescent dye solution (Gdye group, 30) followed by parotidectomy preserving the facial nerve, measuring the time for localization and facility of localization (LocTime and LFN). Nerve function was assessed using the Vibrissae Movements (PMV) and Eyelid Closure Motion (PFP) scores. RESULTS Nerve localization was faster in Gdye group, with 83% Easy LFN rate. The Gdye group presented with low nerve injury degree and better PMV and PFP scores, with high sensitivity and accuracy. CONCLUSIONS This experimental method of facial nerve fluorescence was effective for intraoperative nerve visualization, identification and preservation. The technique may be used in future facial nerve studies, translated to humans, contributing to the optimization of parotid surgery in the near future.

ABSTRACT

Introdução: As neoplasias de glândulas salivares correspondem a cerca de 3% a 10% dos tumores em cabeça e pescoço, com incidência anual de 1/100.000 casos. A idade média é de 45 anos, no gênero feminino. Nas neoplasias benignas, a incidência anual é de 4,7%, mais da metade em glândulas salivares maiores e tipo mais comum o Adenoma Pleomórfico. As neoplasias malignas tem incidência anual de 0,9%, gênero masculino e Carcinoma Mucoepidermóide em glândulas parótidas. Objetivo: Determinar as características demográficas, clínicas e histológicas dos pacientes tratados por neoplasias de glândulas salivares na UNIFESP retrospectivamente no período de 10 anos. Material e Métodos: Análise retrospectiva dos prontuários de pacientes tratados por neoplasias de glândulas salivares no Departamento de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço da Universidade Federal de São Paulo-UNIFESP, no período de 10 anos (2002 a 2012). Para análise descritiva utilizou-se o Microsoft Excel 2011 e teste t-student com significância p<0,05. Resultados: As mulheres compreenderam 55%, maioria entre as neoplasias malignas (60%) e benignas (85%), idade média de 52 anos. Sintoma inicial de dor: 62,5% das malignas e 18,9% das benignas. Tempo médio de apresentação de 4,6 anos para as malignas e 2,7 anos para as benignas, diagnóstico com a punção em 89,4%. Ambas neoplasias acometeram a glândula parótida (81,9%). O Carcinoma Mucoepidermóide e o Adenoma Pleomórfico foram os mais comuns. Complicações ocorreram em 23,4%: paralisia facial periférica (13,8%) e hematomas (6,4%). Conclusões: Os dados epidemiológicos, a sensibilidade, especificidade e acurácia da punção concordam com a literatura. Maior incidência de neoplasias em parótida, mais comum o Carcinoma mucoepidermóide. A Parotidectomia com preservação do facial, com ou sem esvaziamento cervical foi a cirurgia mais comum realizada e maior incidência de metástases cervicais ocultas.


Introduction: The salivary gland neoplasms are about 3% to 10% of all head and neck tumors, with annual incidence of 1/100.000 habitants. The medium age of presentation is 45 years in the female. In the benign neoplasms, the annual incidence is 4,7%, more than half in the major salivary glands and the pleomorfic adenoma is the commonest subtype. The malignant neoplasms has 0,9% of annual incidence, being more common in the male and the Mucoepidermoid subtype in the parotid gland. Objective: To determine retrospectively the clinical, demographic and histopathological characteristics of a consecutive series of surgical treated patients due salivary gland neoplams in the UNIFESP in a ten years period. Material and Methods: Retrospective analisys from clinical data of treated patients due salivary gland neoplasms in the Otorhinolaryngology Head and Neck Surgery Department at Sao Paulo Federal University in a ten years period (2002-2012). The Microsoft excel was used to descriptive analisys with t-student with p<0,05 significance. Results: The female patients were 55% of all, even in the malignant neoplasms (60%) or in the benign ones (85%). The medium age was 52 years and the initial symptom was pain in 62,5% of the malignant and in the 18,9% in the benign neoplasms. The main time of duration of symptoms was 4,6 and 2,7 years for the malignant and benign neoplasms respectively. In 89,4% of patients the diagnosis was made by the aspirative biopsy. The parotid gland was majority in both malignant and benign histology (81,9%), the Mucoepidermoid carcinoma and the pleomorfic adenoma were the commonest histology. Complications occurred in 23,4% of the patients, divided in periferic facial paralysis (13,8%) and hematoma (6,4%). Conclusion: The epidemiological data, the sensivity, especificity and accuracy of aspirative biopsy agree with the current literature. The parotid was the principal gland with disease and the mucoepidermoid carcinoma the main malignant neoplasm. Parotidectomy with preservation of the facial nerve, followed by neck dissection was the commonest surgery and we found a higher incidence of occult lymph node metastasis.

ABSTRACT

CONTEXT: neuroglial ectopia has been defined as a mass composed of differentiated neuroectodermal tissue isolated from the spinal canal or cranial cavity and remains rare. This lesion has to be considered in the differential diagnosis among newborn infants with classical symptoms of respiratory distress, neck mass and feeding difficulties. We present a rare case of extensive parapharyngeal and skull base neuroglial ectopia in 6-month-old girl who presented respiratory and feeding obstruction at birth. CASE REPORT: a six-month-old girl who presented upper respiratory and feeding obstruction at birth and was using tracheostomy and gastrostomy tubes was referred to our institution. Complete surgical excision of the mass consisted of a transcervical-transparotid approach with extension to the infratemporal fossa by means of a lateral transzygomatic incision, allowing preservation of all vital neurovascular structures. The anatomopathological examination showed a solid mass with nests of neural tissue, with some neurons embedded in poorly encapsulated fibrovascular stroma, without mitotic areas, and with presence of functioning choroid plexus in the immunohistochemistry assay. Neurovascular function was preserved, thus allowing postoperative decannulation and oral feeding. Despite the large size of the mass, the child has completed one year and six months of follow-up without complications or recurrence. Neuroglial ectopia needs to be considered in diagnosing airway obstruction among newborns. Surgical treatment is the best choice and should be performed on clinically stable patients. An algorithm to guide the differential diagnosis and improve the treatment was proposed.

ABSTRACT

The objective of this study was to describe the rare thyroid MALT lymphoma concomitant with papillary thyroid carcinoma in a male patient who was submitted to total thyroidectomy. Treatment and follow-up issues are addressed. Male patient complains of fast thyroid enlargement without lymphadenophaty and normal clinical exams. Total thyroidectomy was indicated and performed without any complications. The pathology showed multicentric papillary thyroid carcinoma, concomitant thyroid MALT lymphoma and Hashimoto's thyroiditis. The immunohistochemistry assay was positive for CD 20, CD 43, CD 79, AE1/AE3. The staging studies showed no evidence of both metastasis, Ann Harbor stage IE, without B symptoms. After RIT no further radiotherapy or chemotherapy was indicated. Nowadays the thyroglobulin is undetectable, without recurrences at two years of follow-up. It was concluded that primary thyroid MALT lymphoma is uncommon being the papillary thyroid carcinoma more frequent. Both occurring concomitantly is very rare and the treatment has to prioritize the tumor of worst prognosis at the discovery moment.

O objetivo deste trabalho foi descrever um raro linfoma MALT primário de tireoide concomitante com carcinoma papilífero em paciente masculino submetido à tireoidectomia total. O tratamento e o seguimento são discutidos no texto. Paciente masculino com rápido aumento da tireoide sem linfonodomegalias com exames normais. A tireoidectomia total foi indicada e realizada sem complicações. O anatomopatológico mostrou carcinoma papilífero multicêntrico concomitante com linfoma MALT e tireoidite de Hashimoto. A imuno-histoquímica foi positiva para CD 20, CD 43, CD 79, AE1/AE3. O estadiamento clínico não demonstrou evidência de metástases de ambos, Ann Harbor estádio IE, sem sintomas B. Realizado RIT sem radioterapia ou quimioterapia. Atualmente se encontra com tireoglobulina indetectável, sem recidivas ao seguimento de dois anos. Concluiu-se que o linfoma MALT primário de tireoide é raro e o carcinoma papilífero é o mais frequente com boa evolução. A concomitância de ambos é muito rara e o tratamento deve priorizar a neoplasia que apresenta o pior prognóstico no momento da descoberta.
