Neoplasias de Glândulas Salivares: Estudo Retrospectivo de 134 casos numa população do Nordeste do Brasil / Salivary gland neoplasms: a retrospective study of 134 cases in a population from the northeast of Brazil

RESUMO

Objetivo: determinar a prevalência de neoplasias das glândulas salivares diagnosticadas no Hospital Dr. Napoleão Laureano, em João Pessoa-PB. Metodologia: Realizou-se um estudo retrospectivo dos laudos emitidos entre 1996 e 2003. Resultados: Cento e trinta e quatro casos recuperados dos arquivos foram considerados para análise, 94 (70,1%) benignos e 40 (29,9%) malignos. Os pacientes apresentavam idades entre 9 e 97 anos (média de 44,7), sendo que a maioria estava na faixa etária de 50 a 59 anos (25,2%). As formas malignas foram mais frequentes na sexta década (11%), e as benignas, na quinta década (15,4%). Noventa e um pacientes (67,1%) eram mulheres, e houve predominância feminina para as neoplasias benignas (74,5%) e malignas (52,5%). Na parótida, ocorreram 76 casos (60,3%), sendo 63 (82,8%) benignos e 13 (17,2%) malignos. O adenoma pleomórfico foi o mais comum dos tumores benignos (83%), enquanto o carcinoma adenoide cístico prevaleceu entre os malignos (60%). Conclusão: Mulheres na faixa etária entre 40 e 60 anos foram as mais acometidas por tumores de glândulas salivares, que se configuraram, principalmente, como adenomas pleomórficos, dentre os benignos, e como carcinomas adenoides císticos, dentre os malignos, tendo sido a glândula parótida a mais afetada.

ABSTRACT

Aim: The aim of this study was to analyze the prevalence of salivary gland neoplasms diagnosed at Dr. Napoleão Laureano Hospital in João Pessoa-PB. Methods: The case files of patients diagnosed with salivary gland neoplasms between 1996 and 2003 were reviewed. Results: One hundred and thirty-four cases retrieved from the files were considered for analysis. Ninety-four neoplasms (70.1%) were benign and 40 (29.9%) were malignant. The patients' ages ranged from 9 to 97 years (mean, 44.1 y), and the largest proportion (25.2%) was in the 50-59 y age group. The malignant forms were most frequent in those aged 50-59 y and the benign ones in those aged 40-49 y. Ninety-one patients (67.9%) were women, with a female predominance for both benign (74.5%) and malignant (52.5%) neoplasms. The majority (82.9%) of the 76 tumors located in the parotid glands were benign. Pleomorphic adenoma was the most common benign neoplasm (83%), while adenoid cystic carcinoma was the most prevalent malignant one (60%). Conclusion: Women aged between 40 and 60 years were the most affected by salivary gland tumors, particularly pleomorphic adenomas among the benign ones and adenoid cystic carcinomas among the malignant ones, the parotid being the most affected gland.
