dc.description.abstractTo determine the accuracy of fine-needle aspiration (FNA) in the diagnostic assessment of lymphadenopathies, a retrospective study was conducted on 627 cases of FNA of the lymph nodes performed at Department of Pathology, UNIFESP (Federal University of Sao Paulo), between 1997 and 2001. Cytology results were compared to the results of biopsies if available. The cytological diagnosis was unsatisfactory in 14.7% of cases, positive in 46%, and negative in 39.3%. Among the positive cases, 79.4% were classified as metastases, 14.2% as lymphoma, and 6.4% as indeterminate. Anatomopathological exams for the determination of cytohistological correlation were available in 218 of the 627 cases. There were three (1.88%) false-negative and two (1.25%) false-positive cases. Accuracy tests revealed 97.41% sensitivity, 95.45% specificity, and 96.88% efficacy, with cytohistological agreement being almost perfect (kappa = 0.92). The high accuracy of this study based only on cytomorphological criteria associated to the variety of malignant neoplasias diagnosed by the procedure demonstrates its relevance on patient care, especially in areas of limited financial resources.en
dc.description.abstractPara determinar a precisão da aspiração por agulha fina (PAAF) na avaliação diagnóstica das linfadenopatias, foi realizado um estudo retrospectivo em 627 casos de PAAF dos linfonodos realizados no Departamento de Patologia, UNIFESP (Universidade Federal de São Paulo), entre 1997 e 2001. Os resultados citológicos foram comparados com os resultados das biópsias, se disponíveis. O diagnóstico citológico foi insatisfatório em 14,7% dos casos, positivo em 46% e negativo em 39,3%. Entre os casos positivos, 79,4% foram classificados como metástases, 14,2% como linfoma e 6,4% como indeterminados. Exames anatomopatológicos para a determinação da correlação cito-histológica estavam disponíveis em 218 dos 627 casos. Houve três (1,88%) casos falso-negativos e dois (1,25%) casos falso-positivos. Os testes de precisão revelaram sensibilidade de 97,41%, especificidade de 95,45% e eficácia de 96,88%, com concordância cito-histológica quase perfeita (κ = 0,92). A alta acurácia deste estudo, baseada apenas em critérios citomorfológicos associados à variedade de neoplasias malignas diagnosticadas pelo procedimento, demonstra sua relevância no atendimento ao paciente, principalmente em áreas com recursos financeiros limitados.
