Evaluation of fine needle aspiration biopsy in oral cavity and head and neck region with different stains techniques.

The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin (H&E) stains. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutively, with nodular lesions in the oral cavity and head and neck region. The material obtained by FNAB was sent on 6 different slides, stained by the method of Panoptic, Papanicolaou and H&E, to the same pathologist only with the clinical diagnosis. After the final report of FNAB, the biopsy report was issued, serving as gold standard. After the calculations, the results of sensitivity, specificity and accuracy for Panoptic staining were 28.6%, 76% and 15.4%, respectively. The result of sensitivity, specificity and accuracy for Papanicolaou staining were 71.4%, 76.7% and 23.3%, respectively. The result of sensitivity, specificity and accuracy for H&E staining were 82.1%, 23.3%, 28.6%, respectively. We can conclude, according to the methodology of this study that, H&E and Papanicolaou stains showed the same sensitivity of diagnosing malignant neoplasms. H&E stain showed a better specificity for diagnosing benign neoplasms, compared with Papanicolaou and Panoptic stains. H&E stain showed better accuracy, to give definitive diagnosis, followed by Papanicolaou and Panoptic stains.

Avaliação da punção aspirativa por agulha fina (PAAF) em cavidade oral e região de cabeça e pescoço em diferentes técnicas de coloração / Evaluation of fine needle aspiration biopsy (FNAB) in oral cavity and head and neck region with different techniques stains

O presente estudo teve como objetivo avaliar a Punção Aspirativa por Agulha Fina (PAAF) em diferentes técnicas de coloração, em lesões nodulares de cavidade oral e região de cabeça e pescoço, quanto a sua sensibilidade, especificidade e acurácia, nas colorações de Panótico, Papanicolau e Hematoxilina-Eosina . Foram selecionados 46 pacientes consecutivamente que procuraram a Clínica da Disciplina de Estomatologia Clínica da FOUSP, portadores de lesões nodulares em cavidade oral e região de cabeça e pescoço. Como critérios de inclusão foram selecionados pacientes de ambos os sexos, todas as etnias, acima dos 5 anos de idade, sem restrição de comorbidades e que foram realizadas PAAF com confirmação diagnóstica pela biópsia. Como critérios de exclusão da pesquisa estão os pacientes abaixo dos 5 anos de idade e pacientes que foram somente submetidos a PAAF sem confirmação diagnóstica pela biópsia. O material obtido pela PAAF foi enviado em 6 lâminas diferentes, corados pelo método de Panótico, Papanicolau e Hematoxilina-Eosina a um mesmo patologista apenas com o diagnóstico clínico. Após a emissão do laudo da PAAF, o laudo do anátomo patológico era emitido, servindo como padrão ouro. Após os cálculos, o resultado da sensibilidade, especificidade e acurácia para o método de coloração com o Panótico foram de 28,6%, 76%, 15,4, respectivamente, para o método de coloração com o Papanicolau foram de 71,4%, 76,7%, 23,3%, respectivamente e para o método de coloração com a Hematoxilina-Eosina foram de 82,1%, 23,3%, 28,6%, respectivamente...

Fine needle aspiration biopsy in the oral cavity and head and neck region.

The objective of the current study was to evaluate the sensitivity, specificity and accuracy of fine needle aspiration biopsy (FNAB) of submucous nodules from the oral cavity and head and neck region as an auxiliary diagnostic tool. Fifty patients with nodule lesions in the oral cavity and the head and neck region were selected. All of them were submitted to FNAB and to either incisional or excisional biopsy. The diagnoses from the FNABs were compared with the biopsy diagnosis as the gold standard. All the cases of FNAB were analyzed by a single oral pathologist prior to the biopsy diagnosis. The results showed that the sensitivity of FNAB was 75%, its specificity was 96% and its accuracy was 58.8%. The false positive and false negative rates were 6.7% and 13.3%, respectively. The positive predictive value was 86% and the negative predictive value was 93%. The inconclusive rate was 16/50. FNAB displayed a high success rate for identifying both malignant and benign lesions, but a low accuracy for making a final diagnosis.

Análise comparativa da punção aspirativa por agulha fina (PAAF) em relação a biópsia em cavidade oral e região de cabeça e pescoço / Comparative analysis of Fine Needle Aspiration Biopsy (FNAB) versus biopsy in oral cavity and head and neck region

O presente estudo teve como objetivos avaliar a sensibilidade, a especificidade e a acurácia da Punção Aspirativa por Agulha Fina (PAAF) em nódulos submucosos da cavidade bucal e da região de cabeça e pescoço como ferramenta auxiliar de diagnóstico. Foram selecionados 50 pacientes consecutivamente que procuraram a Clínica da Disciplina de Estomatologia Clínica da FOUSP, portadores de lesões em boca e em região de cabeça e pescoço. O material obtido pela PAAF foi enviado a um mesmo patologista apenas com o diagnóstico clínico e após a emissão do laudo da PAAF o laudo do anátomo patológico era emitido servindo como padrão ouro. Após os cálculos, o resultado da sensibilidade foi de 75%, a especificidade foi de 96%, a acurácia foi de 58,8%, o valor preditivo positivo foi de 86% e o valor preditivo negativo foi de 93%. A significância foi estabelecida para 5% e o teste usado foi o teste de Kappa com valor de P<0,001 e um teste qui-quadrado, com valor de P=0,788. Pela análise dos resultados a PAAF teve uma alta sensibilidade para identificar lesões malignas, uma alta especificidade para identificar lesões benignas e uma baixa acurácia para se obter um diagnóstico definitivo.

The material obtained by FNA was sent to only one pathologist with the clinical diagnosis and after the emission of FNAB report the biopsy report was emitted serving as the gold standard. After the calculation, the results of sensibility was 75%, the specificity was 96%, the accuracy was 58,8%, the positive predict value was 86% and the negative predict value was 93%. The significance was established for 5% and the tests used was Kappa with P<0,001 and a Chi-square with a P value of 0,778.With the results analysis the FNAB had a high sensibility to identify malignant lesions, a high specificity to identify benign lesions and a low accuracy to obtain final diagnoses.
