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.

Abordagem do câncer da boca: uma estratégia para os níveis primário e secundário de atenção em saúde / Strategies for management of oral cancer in primary and secondary healthcare services

O avanço verificado no enfrentamento de neoplasias malignas por meio dos sistemas de saúde envolve melhorias nas áreas de vigilância, organização de redes de assistência, programas específicos voltados às prevenções primária e secundária e, obviamente, aos avanços técnico-científicos que caracterizam a abordagem diagnóstica e terapêutica. Embora seja notável o reconhecimento de avanços no manejo de neoplasias malignas em todas as áreas citadas, o câncer da boca permanece com indicadores de morbidade e mortalidade que parecem não acompanhar o acúmulo científico no conhecimento da doença. O presente manuscrito objetiva discutir os motivos desse descompasso, a necessidade de reorientação de prioridades na abordagem do câncer da boca e sua efetivação como política pública de saúde.

Progress in cancer management by health systems involves improvements in surveillance, organization of healthcare services, specific programs focused on primary and secondary prevention, and scientific and technical advances in diagnosis and treatment. Despite well-known progress in the management of malignant neoplasms in all the above areas, oral cancer displays persistently high morbidity and mortality rates, apparently failing to reflect the accumulated scientific knowledge on the disease. The current article discusses the reasons for this mismatch, the need for redefining priorities in oral cancer management, and the implementation of such priorities as a public health policy.
