Freqüência de realização e acurácia do auto-exame das mamas na detecção de nódulos em mulheres submetidas à mamografia Frequency of performance and accuracy of breast self-examination in the detection of breast lumps in women who underwent mammographic examination

Abstract

Realizamos um estudo transversal prospectivo cujo objetivo foi avaliar a acurácia do auto-exame de mamas (AEM) na detecção de nódulos mamários palpáveis e a relação com sua freqüência. Foram entrevistadas 2672 mulheres que realizaram mamografia na Região do Vale dos Sinos/RS no período de janeiro de 94 a julho de 97, questionando-se quanto à freqüência da realização de AEM. As mulheres foram divididas em dois grupos: grupo I (mensalmente), grupo II (quase nunca). As mulheres que relataram realizar o AEM ocasionalmente foram excluídas da análise principal. Foi perguntado à paciente se ela ou seu médico haviam palpado alguma lesão mamária. Comparou-se os achados de palpação da paciente com os do médico (relatados pela paciente). A sensibilidade do AEM foi maior no grupo I comparado ao II (57,4% versus 33,3%; P We conducted a prospective cross-sectional study to evaluate the accuracy of the breast self-examination (BSE) in the detection of palpable breast lumps and the relation to its frequency of performance. Two thousand six hundred and seventy two women who have had a mammogram in a private clinic in Vale dos Sinos-RS between January 1994 and July 1997 were asked about BSE performance frequency. They were divided in two groups: group I (monthly), group II (almost never). The women who referred performing BSE on a occasional basis were excluded from the main analysis. The woman was asked wheter she or her physician had palpated something in her breasts. The patient's BSE findings were compared with those of her physician (based on the patients' report). The sensitivity of the BSE was higher in group I compared to group II (57.4% versus 33.3%; rho<0.05). We concluded that there is an association between frequency of performance and sensitivity of BSE to detect breast lumps.
