Purpose: This study aimed to assess the usefulness of second-look ultrasounds
performed on suspicious lesions found from breast MRIs which were taken as preoperative
evaluations of breast cancer.
Materials and Methods: From May 2008 to July 2011, second-look ultrasounds
were performed for 98 lesions in 80 patients that were initially detected on preoperative
breast MRIs for known breast cancer. In this study, identification was made on the
findings from second-look ultrasounds on the target lesions. The histopathological
results were used to assess the effects of second-look ultrasounds on the treatment
plans for patients, in the context of operation records.
Results: Among the total 98 lesions, sonographic correlation was made in 85
lesions (87%). In total, 82 lesions were identified with histopathological results. Among
them were 18 malignancies (22%) and 64 benign lesions (78%). Sonographically-correlated
lesions showed a higher prevalence for malignancy (20% [17/85]) than noncorrelated
lesions (8% [1/13]). From 44% (43/98) of the total target lesions, the unnecessary
expansion of the extent of surgical resection was suppressible through second-
look ultrasounds.
Conclusions: Second-look ultrasounds subsequent to breast MRIs in patients with
breast cancer are useful for preoperative evaluation and enables them to make the
histopathological confirmation of suspicious lesions conveniently found from breast
MRIs. |
