Purpose Accurate assessment of residual disease after neo‐adjuvant chemotherapy (NEC) for women with locally advanced and inflammatory breast cancer (LABC) is critical for planning surgery. The study's purpose was to prospectively determine the optimal method (clinical examination (CE), mammogram (MG), and magnetic resonance imaging (MRI)) for assessing residual disease after NEC for women with LABC. Methods Women with LABC who received NEC and surgery were enrolled. Patient demographics, tumor size as measured by CE, MG, and MRI both before and after NEC, and final pathologic size of tumor were collected. Response to NEC was calculated using RECIST criteria. Paired t ‐tests and the Pearson correlation were used to compare tumor size on CE, MG, MRI, and final pathology. Results Forty‐eight women with 50 LABC were recruited. Mean pre‐NEC tumor size was 8.2, 5.1, and 6.2 cm on CE, MG, and MRI. Mean post‐NEC tumor size was 2.4, 4.3, 3.9, and 3.6 cm on CE, MG, MRI, and final pathology. The Pearson correlation co‐efficient between post‐NEC measurements and pathology was 0.63 (CE), 0.15 (MG), and 0.49 (MRI). Conclusion We found that there was limited correlation between the extent of residual disease after NEC for patients with LABC as assessed by CE, MG, and MRI as compared to final pathology. J. Surg.
