Type of surgical closure technique used during lumpectomy may impact the pattern or density of scar tissue apparent in the tumor bed on mammography. This study sought to determine whether surgical closure type affects tumor-bed scar formation and impacts interpretation of surveillance mammography in women treated with breast-conserving therapy for early-stage breast cancer. MATERIALS AND METHODS:: One hundred women who received breast-conserving therapy were selected; 99 of them had 2-year post-treatment mammograms for the treated breast. Craniocaudal and mediolateral oblique views were reviewed by 3 subspecialty radiologists who routinely read mammograms. The mammograms were scored on 5-point scales for overall breast density and scarring within the tumor bed. RESULTS:: The analyses did not demonstrate greater scarring or density in breast status post superficial closure compared with breast status post full-thickness closure, or vice versa (P > 0.05 for scarring and density). There were no detectable differences between the 2 closure techniques either within the data from individual reviewers, within the composite data for the entire group of reviewers, or in instances where 2 of 3 reviewers agreed (P > 0.05). There was significant interobserver variability in scoring among the mammographers for both scarring (P = 0.001) and density (P < 0.0001). CONCLUSION:: Based on our study of the 2-year post-treatment mammograms, there was no evidence that closure technique impacts degree of scarring in the tumor bed. However, striking interobserver variability in scoring density and scarring was noted.
