Decision making in favor of conservative breast surgery is dependent upon the accuracy of preoperative evaluation of tumor stage, of which imaging modalities occupy a pivotal role.
Systematic studies correlating the relative accuracy of various evaluating strategies are few, but remain vital means of making the optimal selection of diagnosis and subsequent treatment option.
In this study, we evaluated the relative efficacy of : (I) palpation (P), (2) ultrasonography (US), and (3) bilateral mammography (MG) of the breast and axilla.
In a prospective study, 109 female patients undergoing a modified radical mastectomy were subjected to a preoperative diagnostic assessment protocol involving palpation, ultrasonography, and bilateral mammography of the breast and axilla.
Subsequently the preoperative findings were correlated to the postoperative histopathological reports.
Cancer-specific criteria evaluated were tumor size, location, histologic type, histoarchitecture, and calcification, as well as status of regional nodes.
Patient-specific criteria included age, size, and density of the breast and presence of associated benign breast disease.
Percentage sensitivity, specificity, and positive and negative predictive values were determined for MG, US, and P as well as MG+P and US+P. Results :
In assessment of the primary tumor,
MG, and US showed an overall sensitivity of 88%, 92%, and 90%, respectively ;
MG+P and US+P had a sensitivity of 99% each. (...)
