“…Sendo assim, de acordo com Pehlivan 8 (2019) a prevalência da doença está relacionada ciência plural à ação de agentes físicos e químicos com potencial mutagênico, e que dentre eles a combinação de tabaco com o consumo de bebidas alcoólicas é a causa de 65% a 90% das neoplasias bucais.…”

Introdução: Os tumores de cabeça e pescoço, têm expressiva incidência e mortalidade, assim como alta letalidade, e constituem um relevante problema de saúde pública, particularmente nos países em desenvolvimento. Dentre as neoplasias malignas diagnosticadas no mundo, aproximadamente 10% estão localizadas na boca, sendo esse o sexto tipo de câncer mais incidente. Objetivo: Avaliar o perfil epidemiológico de pacientes diagnosticados com câncer de boca e faringe da Liga Mossoroense de Estudos e Combate ao Câncer do município de Mossoró, RN, entre janeiro 2013 e junho de 2018. Metodologia: Estudo transversal, fundamentado na análise retrospectiva e descritiva de prontuários médicos. Resultados: Dos 221 prontuários analisados, a cor branca (56,6%) e o gênero masculino (70,6%) foram os mais prevalentes, com média de idade entre 55 e 65 anos. A maioria (61,9%) apresentava ensino fundamental incompleto, sendo residentes de área urbana (59,6%) com histórico de uso de tabaco (64,6%) e/ou bebidas alcoólicas (53,9%). O sítio mais prevalente de câncer em boca foi a base da língua (12,7%). Conclusões: Conhecer o perfil dos pacientes com câncer de boca e orofaringe é um importante passo para melhor traçar e direcionar ações de saúde pública visando tanto à prevenção quanto o diagnóstico precoce.

“…Patients over 18 years of age, presenting with lymph nodes suspected of malignancy in the neck and axilla on US, were evaluated prospectively. In B-mode US, long axis/short axis ratio >2 in the lymph node, >1 cm in the short axis, increased cortex thickness (>2.5 mm), absence of fatty hilus were regarded as a suspicion of malignancy ( 4 , 5 , 6 ) . The lymph nodes which were suspicious for malignancy were followed-up for 12 weeks with an appropriate antibiotic therapy.…”

“…In B-mode US, the features of lymph nodes suspicious for malignancy (i.e. irregular shape, increased size, pronounced hypoechogenicity, presence of micro/macro calcification, short axis/long axis ratio >2, increased size of the short axis, increased cortex thickness, obliterated hilus or increased cortex thickness >3.5 mm) were described as abnormal ( 5 , 6 ) . Resistivity index (RI), pulsatility index (PI), and acceleration rate and time were evaluated for intranodal arterial structures on color Doppler US, and the strain ratio value and elasticity scores were recorded on USE.…”

Aim: In this prospective study, the efficiency of imaging findings was investigated by comparing the histopathological results of lymph nodes with Doppler and ultrasound features and elasticity scores. Material and method: A total of 100 cervical or axillary lymph nodes with a suspected malignancy or whose size did not decrease after treatment were examined. In addition to the demographic data of the patients, B-mode ultrasound, Doppler ultrasound, and elastography features of the lymph nodes were evaluated prospectively. The irregular shape, increased size, pronounced hypoechogenicity, presence of micro/macro calcification, short axis/long axis ratio >2, increased size of the short axis, increased cortex thickness, obliterated hilus or increased cortex thickness >3.5 mm were evaluated on ultrasound. Resistivity index, pulsatility index, acceleration rate and time were evaluated for intranodal arterial structures on color. Doppler ultrasound, strain ratio value and elasticity score were recorded on ultrasound elastography. After sonographic examination, patients underwent ultrasound-guided fine needle aspiration cytology or tru-cutting needle biopsy. Histopathological examination results of the patients were compared with the B-mode ultrasound, Doppler ultrasound, and ultrasound elastography. Results: When the individual and combined effects of the ultrasound, Doppler ultrasound, and ultrasound elastography were evaluated, the combination of all three imaging methods was found to have the highest sensitivity and the highest overall accuracy (90.4% and 73.9%). As an individual method Doppler ultrasound had the highest specificity (77.8%). B-mode ultrasound was found to have the lowest accuracy (56.7%) both in individual and combined evaluations. Conclusion: Addition of ultrasound elastography to the combination of B-mode and Doppler ultrasound findings increases diagnostic sensitivity and accuracy in the differentiation of benign and malignant lymph nodes.

“…In a 5-point rating scale (3,12,16,18), Tan et al reported that 50 of malignant and 74.5% of metastatic LNs manifested pattern 3 or 4, while all primary malignant LNs manifested pattern 2 (3). In another study including 97 axillary LNs, using the criteria of score 1 and 2 as benign and scores 3, 4, and 5 as metastatic, the sensitivity, specificity, PPV, NPV, and accuracy were 78%, 93%, 93%, 79%, and 86%, respectively (16).…”

Ultrasound Elastography for the Evaluation of Lymph Nodes

The differential diagnosis of lymphadenopathy is important for predicting prognosis, staging, and monitoring the treatment, especially for cancer patients. Conventional computed tomography and magnetic resonance imaging characterize lymph node (LN) with disappointing sensitivity and specificity. Conventional ultrasound with the advantage of high resolution has been widely used for the LN evaluation. Ultrasound elastography (UE) using color map or shear wave velocity can non-invasively demonstrate the stiffness and homogeneity of both the cortex and medulla of LNs and can detect early circumscribed malignant infiltration. There is a need of a review to comprehensively discuss the current knowledge of the applications of various UE techniques in the evaluation of LNs. In this review, we discussed the principles of strain elastography and shear wave-based elastography, and their advantages and limitations in the evaluation of LNs. In addition, we comprehensively introduced the applications of various UE techniques in the differential diagnosis of reactive LNs, lymphoma, metastatic LNs, and other lymphadenopathy. Moreover, the applications of endoscopic UE and endobronchial UE are also discussed, including their use for improving the positive rate of diagnosis of fine-needle aspiration biopsy.

Diagnostic role of ultrasound elastography on lymph node metastases in patients with head and neck cancer

Abstract: Ultrasound elastography is helpful for the diagnosis of lymph node metastases in patients with head and neck cancer. Due to its non-invasive character, it can be used safety in combination with other radiological techniques to support or improve their diagnostic performance.
