RESUMO
OBJECTIVE: To evaluate the ability of the variables Muscle Mass percentage (%MM), Body Fat percentage (%BF), Phase Angle (PhA), and Standardized Phase Angle (SPhA) to predict overall survival rates in individuals with surgically treated HNC. METHODS: A prospective cohort study of surgically treated HNC patients was carried out between 2017 and 2022 at a cancer referral center in Feira de Santana, Bahia. All subjects were seen by an experienced dietitian the week before surgery. During this visit, patients had their sociodemographic and clinical data collected, as well as anthropometric measurements (weight and height) and BIA variables. In this study, postoperative overall 5-year survival was defined as the time in months between the date of surgery and the date of death, regardless of the cause of death. Patients were followed up after surgery until death. RESULTS: Seventy-eight older adult patients were consecutively included. Patients had a median age of 65.5-years, were mostly men (83.3%), and most had low education levels (62.3%) and low household income, ranging from zero (19.2%) to the minimum wage (60.2%). They were mostly alcohol drinkers (91%) and tobacco smokers (87.2%). Glottic cancer was diagnosed in 48.7% of patients, with 44.8% of cases with stage-IV disease. Forty (51.2%) deaths were recorded in the follow-up period, with a median survival time of 39 months. Variables %MM, %BF, and SPhA were not significantly different between groups (alive vs. dead patients). PhA was considered an independent predictor of overall survival, with an accuracy of 69% (95% CI 0.57â0.80). When comparing survival curves, patients with a preoperative PhA < 6.8° were more than twice as likely to die during follow-up (HRâ¯=â¯2.38; pâ¯=⯠0.02; 95% CI 1.14â4.97). CONCLUSION: Out of the assessed BIA variables, preoperative PhA was considered a good predictor of overall survival after HNC surgery.
RESUMO
INTRODUCTION: The prevalence of malnutrition is high among head and neck cancer (HNC) patients and negatively impacts their quality of life, treatment, and survival rates. OBJECTIVE: To identify preoperative nutritional variables capable of predicting postoperative complications in surgically treated HNC patients. METHODS: This was a prospective cohort study of HNC patients referred for surgery as initial treatment. RESULTS: Sixty patients were included in the study; they had a median age of 65.5 years, were mostly me n (85%), and most had low education levels (90%) and low household income (78.3%). The incidence rate of severe postoperative complications (grades II, III, IV, and V according to the Clavien-Dindo grading system) was found to be 50%. The nutritional variables under investigation, namely calf circumference (CC), triceps skinfold, body mass index, and adductor pollicis muscle thickness were shown to predict postoperative complications in HNC patients, especially CC, which was found to be an independent predictor of complications (OR=0.8; 95%CI: 0.650.96). Each 1-cm increase in calf circumference was associated with a 20% decrease in the risk of postoperative complications. CONCLUSION: Our findings show the nutritional variables studied are useful in the prognostic assessment of HNC surgery.

BACKGROUND: Malnutrition is a common issue in patients with head and neck squamous cell carcinoma and has a negative effect on surgical outcomes. OBJECTIVE: We attempted to determine which malnutrition diagnostic variables can be used as predictors of postoperative complications in patients with head and neck squamous cell carcinoma. METHODS: Forty-one patients undergoing surgery for head and neck squamous cell carcinoma were submitted to a prospective evaluation. Biochemical data, anthropometric measurements and evaluation of body composition were used in the nutritional analysis. RESULTS: Twenty-two patients (53.6%) developed complications. Serum albumin measured on the first postoperative day was the only variable that significantly differed between groups. A cut-off value of 2.8â¯g/dL distinguished between patients with a complicated and uncomplicated postoperative course. Normalization of albumin levels occurred more frequently and more rapidly in the noncomplicated group. CONCLUSION: Serum albumin measured on the first postoperative day was the only variable that was a predicter of postoperative complications after major head and neck squamous cell carcinoma surgery.

INTRODUCTION: Surgery is one of the most frequently used options in the treatment of head and neck squamous cell carcinoma. In surgical patients, the use of arterial lactate to assess hypoxemia and severe inflammatory states is well-founded. However, there are few studies on its use in patients with head and neck squamous cell carcinoma. The aim of this study was to investigate whether the serum arterial lactate level on the 1st postoperative day would be a predictor of postoperative complications in head and neck squamous cell carcinoma surgeries. METHODS: This is a prospective cohort, which evaluated 44 adult patients of both genders, with HNSCC, who underwent surgery associated with monobloc neck dissection as an initial treatment. Patients were divided into two groups, according to the presence or absence of postoperative complications: with complication (Clavien-Dindo II-V) and without complications (Clavien-Dindo 0-I). Student's t-test and its variants were used to compare continuous data. Pearson's or Spearman's test was used to correlate the data and p values ââ<0.05 were considered statistically significant. RESULTS: A total of 59% of the patients (n=26/44) developed postoperative complications. Serum lactate was significantly higher in the group with complications when compared to patients without complications, respectively 2.15mmoL/L (1.10-3.90) and 1.59 mmoL/L (0.70-3.44); p=0.03. The prognostic accuracy of arterial lactate was 69% (95% CI: 54%-82%; p=0.03), estimated by the ROC curve. A cut-off >1.7mmoL/L was identified, with a sensitivity of 65.38% and specificity of 66.67%. CONCLUSION: Arterial lactate measured on the first postoperative day is a good predictor of postoperative complications in patients with head and neck squamous cell carcinoma.

Resumo Introdução A cirurgia é uma das opções mais usadas no tratamento do carcinoma epidermoide de cabeça e pescoço. Nos pacientes cirúrgicos, o uso do lactato arterial para avaliação de hipoxemia e de quadros inflamatórios graves é bem fundamentado. Entretanto, existem poucos estudos sobre o seu uso em pacientes com carcinoma epidermoide de cabeça e pescoço. O objetivo deste estudo foi investigar se o lactato arterial sérico no 1° dia de pós‐operatório seria um preditor de complicações pós‐operatórias nas cirurgias do carcinoma epidermoide de cabeça e pescoço. Método Trata‐se de uma coorte prospectiva, que avaliou 44 pacientes adultos, de ambos os gêneros, com carcinoma epidermoide de cabeça e pescoço, submetidos a cirurgia associada ao esvaziamento cervical em monobloco como tratamento inicial. Os pacientes foram divididos em dois grupos, segundo a presença ou não de complicações pós‐operatórias: complicados (Clavien‐Dindo II a V) e sem complicações (Clavien‐Dindo 0-I). Na comparação dos dados contínuos, foi usado o teste t de Student e as suas variantes. Na correlação dos dados, usou‐se o teste de Pearson ou Spearman. Valores de p inferiores a 0,05 (p < 0,05) foram considerados estatisticamente significativos. Resultados Dos pacientes, 59% (n = 26/44) desenvolveram complicações pós‐operatórias. O lactato sérico foi significantemente maior no grupo com complicações em relação aos pacientes sem complicações, respectivamente 2,15 mmoL/L (1,10-3,90) e 1,59 mmoL/L (0,70-3,44); p = 0,03. A acurácia prognóstica do lactato arterial foi de 69% (95% IC 54%-82%; p = 0,03), estimada pela curva ROC. Foi identificado um cut‐off> 1,7 mmoL/L, com sensibilidade de 65,38% e especificidade de 66,67%. Conclusão O lactato arterial do primeiro dia de pós‐operatório é um bom preditor de complicações pós‐operatórias nos pacientes com carcinoma epidermoide de cabeça e pescoço.
RESUMO
Introdução: No tratamento cirúrgico do hiperparatiroidismo primário a localização pré-operatória da glândula acometida é importante, pois permite uma abordagem menos invasiva. Os exames mais utilizados para localizar adenomas de paratireoide são a cintilografia com 99mTc sestamibi (MIBI), a ultrassonografia (US) e a ressonância magnética (RM). Nos casos de localização atípica do adenoma ou associação com patologias tireoidianas, a US pode perder sua acurácia sendo imprescindível a associação com outros métodos. Objetivo: Identificar a sensibilidade, especificidade, valores preditivos positivo e negativo na localização pré-operatória do adenoma de paratireoide de cada exame de imagem isoladamente. Método: Estudo de coorte retrospectivo analisando 40 prontuários médicos de pacientes com diagnóstico de hiperparatireoidismo primário submetidos a paratireoidectomia. Os pacientes foram submetidos a exames localizatórios (cintilografia com Tc99 sestamibi, ultra-sonografia e ressonância magnética). A análise objetivou identificar a sensibilidade, especificidade, valores preditivos positivo e negativo na localização pré-operatória do adenoma de paratireoide de cada exame de imagem isoladamente. Os achados cirúrgicos e histopatológicos foram o padrão-ouro. Resultados: A US apresentou uma sensibilidade de 63%, especificidade de 98%, valor preditivo positivo de 90% e valor preditivo negativo de 89%. A MIBI apresentou uma sensibilidade de 86%, especificidade de 99%, valor preditivo positivo de 96% e valor preditivo negativo de 95%. A RM apresentou uma sensibilidade de 57%, especificidade de 95%, valor preditivo positivo de 80% e valor preditivo negativo de 87%. Conclusão: A cintilografia com TC99 sestamibi é o exame localizatório com melhor sensibilidade e especificidade para identificar adenomas de paratireoide.
Introduction: It is important to allow a less invasive approach to localize preoperatively the adenoma in surgical management of primary hyperparathyroidism. The most common used methods are radionuclide imaging with 99mTc sestamibi (MIBI), ultrasound (US) an magnetic resonance imaging (MRI). In cases of atypical site adenomas or in association with thyroid diseases US can have less accuracy and it?s necessary the association with other imaging methods. Objective: To identify sensibility, specificity, positive and negative predictive values of each individual imaging method in preoperative location of parathyroid adenoma. Method: Retrospective cohort with 40 patients with primary hyperparathyroidism submitted to surgical treatment. The patients underwent localizatory methods (radionuclide imaging with Tc99 sestamibi, ultrasound and magnetic resonance imaging). The study identified sensibility, specificity, positive and negative predictive values of each individual method in preoperative location of parathyroid adenoma. Surgical and histological findings are the gold standart. Results: US has sensibility of 63%, specificity of 98%, positive predictive value of 905 and negative predictive value of 89%. MIBI has sensibility of 86%, specificity of 99%, positive predictive value of 96% and negative predictive value of 95%. MRI has sensibility of 57%, specificity of 95%, positive predictive value of 80% and negative predictive value of 87%. Conclusion: Radionuclide imaging with Tc99 sestamibi is the most sensible and specific imaging method for location of parathyroid adenomas.
RESUMO
A Doença de Castleman (DC) é rara, sendo também conhecidacomo hiperplasia linfonodal gigante. É mais comumenteencontrada em adultos jovens, com predileção pelo mediastino,embora possa ocorrer em qualquer local do sistema linfático. DC édividida em dois subtipos clínicos, unicêntrico e multicêntrico e doistipos histológicos, hialino-vascular e plasmocítico. Relata-se ocaso de paciente de 19 anos, com uma história clínica de massacervical há sete anos. O diagnóstico definitivo foi feito após aressecção e exame histopatológico, que mostrou lesão tipo hialinovascular.Não houve sinais de recidiva após um ano deseguimento.
Castleman's disease (CD) is a rare disorder, also known as giantlymph node hyperplasia. It's more commonly found in young adults,with predilection to mediastinum, although it may occur in any partof the lymphatic chain. CD is divided into two clinical subtypes,unicentric and multicentric, and two histological types, hyalinevascular and plasma cell. A case of a 19-year-old woman, with ahistory of a cervical mass for 7 years is reported. The definitivediagnosis was made after resection and histopathologicalexamination, which showed hyaline vascular type. There was nosign of recurrence after 1 year.
RESUMO
A doença de Madelung é caracterizada por deposição múltipla e simétrica de gordura, acometendo preferencialmente a extremidade superior do corpo, com tendência à recidiva após o tratamento. Difere de outras lipomatoses pela ausência de cápsula envolvendo a lesão. O gênero masculino é o mais acometido. A etiologia parece estar relacionada a uma disfunção mitocondrial ocasionando uma lipólise deficiente. Etilismo está associado à maioria dos casos. A única abordagem terapêutica é o tratamento cirúrgico com remoção das lesões. Apresentamos o caso de um paciente do gênero masculino, etilista, submetido à cirurgia para tratamento da DM.
The Madelung's Disease is characterized by multiple and symmetric fat tissue deposition, affecting the upper body extremity, and with tendency to recurrence after the treatment. There is no capsule involving the lesions, which differs from other lipomatosis. Men are more affected. The etiology seems to be related to the mitochondrial dysfunction resulting in deficient lipolisis. Alcoholism is associated in most cases. The only possible therapeutic approach is surgery with resection of the lesions. We report the case of a man with chronic alcohol use history, submitted to surgery for treatment of the disease.
RESUMO
O carcinoma do ducto tireoglosso (DTG) é incomum, ocorrendo em aproximadamente 1% dos cistos do DTG, sendo em 80% dos casos do tipo papilífero. O carcinoma folicular é ainda mais raro, correspondendo a menos de 6% dos carcinomas do DTG. Relatamos um caso de carcinoma folicular de cisto do DTG em uma mulher de 70 anos. A citologia da punção aspirativa por agulha fina pré-operatória da lesão não foi capaz de estabelecer o diagnóstico de malignidade, sendo este revelado somente através do exame anátomo-patológico do espécime cirúrgico.
The thyroglossal duct cist (TGD) carcinoma is uncommon, occurring in approximately 1% of all TGD cysts. Follicular carcinoma is even rarer, corresponding to less than 6% of all TGD carcinomas. We report a case of TGD cyst follicular carcinoma in a 70-year-old woman. Preoperative fine needle aspiration biopsy could not establish the diagnosis of malignancy. This was only possible with the postoperative histology of the excised lesion.
