Breast Cancer 16:30-6. 2009..The present study was conducted to assess the clinical usefulness of multidetector-row CT (MDCT) in determining the extent of invasive lobular carcinoma (ILC) and especially the extent of residual tumor after neoadjuvant chemotherapy (NAC)...- Comparison among different classification systems regarding the pathological response of preoperative chemotherapy in relation to the long-term outcomeTadahiko Shien
Department of Breast Surgery, National Cancer Center Hospital, Tokyo, Japan
Breast Cancer Res Treat 113:307-13. 2009..All three classifications analyzed were considered inadequate as the prognostic marker of the long-term outcome after NAC and further studies are warranted to optimize the prediction... - 21-Gene expression profile assay on core needle biopsies predicts responses to neoadjuvant endocrine therapy in breast cancer patientsSadako Akashi-Tanaka

Division of Surgical Oncology, National Cancer Center Hospital, Tokyo, Japan
Breast J 11:311-6. 2005..The evaluation of CR by CT was significantly indicative of pCR. The positive predictive value, however, was not large enough to avoid surgical treatment. Further studies will be needed to establish a diagnosis of pCR... - Clinical and pathological features of intracystic papillary carcinoma of the breastTomonori Akagi
