BACKGROUND: @entity12740 ( @entity12740 ) may change the size of the @entity5 defined pathologically at excision. This may alter @entity5 stage and affect recommendations for adjuvant systemic therapy. This study evaluated the effect of @entity12740 on assessment of pathologic @entity5 size and staging for invasive @entity0 presenting as mammographic masses. METHODS: The authors reviewed the mammographic and pathologic size of 138 mammographically detected invasive @entity189 manifested as a measurable mass lesion on mammography and as a 20 mm or smaller lesion on pathologic evaluation. Group A included 61 @entity1 with @entity12740 before surgical excision and the Group B (the control group) included 77 @entity1 who had surgical excision without @entity12740 . The size of the mammographic central mass was compared with the pathologic @entity5 size. The difference between the mammographic and pathologic size was determined and the findings in Group A and B were compared by the Mann-Whitney U test. RESULTS: The mean mammographic size was 12.2 and 11.83 mm and the mean pathologic size was 9.85 and 9.87 mm for Groups A and B, respectively. The mean difference between mammographic and pathologic size in Groups A and B was 2.3 mm and 1.96 mm, respectively (P = not significant). CONCLUSIONS: For soft tissue masses, the difference between mammographic size and pathologic size of invasive @entity189 at excision does not appear to be affected by the use of @entity12740 . Except in the circumstance of complete removal of the @entity5 by @entity12740 , the pathologic size and stage of the excised @entity5 after @entity12740 is not altered significantly by @entity12740 .
