Evaluation of mammographic, ultrasonographic and histopathological characteristics of a series of malign neoplasic lesions of mammary epithelial origin.

Abstract

Background and Objectives: This study’s objective was to evaluate the correlation between mammographic, ultrasonographic and histopathological exams in order for it’s results to be better applied. Methods: The data was retrieved, in a retrospective way, from patient charts whose patients had histopathological confirmation of mammary carcinoma and received treatment from a private clinic in Teresina from January to December of 2008. Results: A data retrieving chart was created, with the objective of relating age, mammographic, ultrasonographic and histopathological evaluations from patients. Histopathological evaluation showed 92,3% of invasive carcinoma, between carcinoma types, the most frequent was ductal, with 88,46%. In the ultrasonographic analysis, the axillary hollow region was affected in 23,8% and the evaluation of suspect lesions revealed nodule as the dominant morphologic aspect with 90,48% and irregular margins of 60%, the average lesional size was 1,5 cm and the most common BI-RADS classification was category IV with 76,2%. Mammographic evaluation showed 31,82% of linfonodomegalia, the dominant morphologic aspect was nodule with 81,81% and the evaluation of lesions revealed irregular margins in 77,7%, the average lesional size was 1,8 cm. The most common category was classification IV with 72,72%. Analyzing the correlation between the two methods, there was an 86,15% agreement. Conclusion: It can be concluded that greater efforts must be employed in order to enable detection of early lesions, given that more than 90% of patients had a type infiltrative lesions and with an average size greater than 1.5 cm diameter.KEYWORDS: Neoplasm.
