PURPOSE The aim of this study was to assess the impact of preoperative magnetic resonance mammography (MRM) on the surgical determination of breast conservation treatment for breast cancer patients. METHODS From September 1997 to March 2000, 57 consecutive breast conservation treatment candidates were prospectively evaluated with conventional imaging(More)
Serous papillary adenocarcinoma of the female genital organs and invasive micropapillary carcinoma of the breast have close histologic similarities. Thus, when these cancers occur synchronously or metachronously in the same patient, it is difficult to determine the primary site. We examined 23 serous papillary adenocarcinomas (16 ovarian, 5 endometrial, and(More)
Purpose This multicenter phase II study examined the impact of pathological effect on survival after preoperative chemotherapy in Japanese women with early stage breast cancer. Patients and methods Prior to surgery, patients received four cycles of FEC (fluorouracil 500 mg/m2, epirubicin 100 mg/m2, cyclophosphamide 500 mg/m2 q3w) followed by four cycles of(More)
PURPOSE A single-arm phase II multicenter trial of the combination of cyclophosphamide (C), epirubicin (E), and 5-fluorouracil (F) followed by docetaxel as neoadjuvant chemotherapy is being conducted by the Japan Breast Cancer Research Group. This report describes an interim analysis of the clinical response and safety of 79 patients who finished(More)
BACKGROUND TSU-68 is a novel multiple tyrosine kinase inhibitor that inhibits vascular endothelial growth factor receptor-2, platelet-derived growth factor receptor, and fibroblast growth factor receptor. This open-label, non-comparative, multicenter phase II study evaluated TSU-68 in combination with docetaxel in patients with metastatic breast cancer that(More)
AIMS To clarify the diagnostic clues of ductal carcinomas in situ (DCIS) associated with papilloma and optimal clinical management of papilloma diagnosed on core needle biopsy (CNB). METHODS AND RESULTS A total of 50 surgically resected cases were examined histopathologically and topographically. Thirty-nine cases (78%) spread in segmental fashion.(More)
The aromatase inhibitors exemestane and anastrozole are approved in Japan for first-line treatment of postmenopausal patients with advanced, hormone-receptor-positive breast cancer. This phase 3, randomized, double-blind study directly compared time to progression (TTP) for exemestane and anastrozole therapy in this patient population. Eligible patients(More)
We conducted a phase II study using docetaxel and trastuzumab as preoperative systemic treatment for locally advanced HER-2-overexpressing breast cancer (stage IIIB or IIIC) to evaluate the efficacy and safety, and to perform a subset analysis based on tumor biomarkers. Patients received 4 mg/kg trastuzumab on day 1, followed by weekly treatments of 2mg/kg,(More)
AIM To examine the histopathological features of 24 surgically resected carcinoma in situ (CIS) involving sclerosing adenosis (SA), with special reference to the topographical relationship between CIS and SA. METHODS AND RESULTS In 13 (54%) lesions, CIS was entirely surrounded by SA (type A) and in 11 (46%), CIS involved SA at least focally but was not(More)
Although apocrine carcinoma is a distinct histologic entity, there is no immunohistochemical marker to confirm apocrine differentiation with high sensitivity and specificity, and its differential cytologic characteristics are still not fully clarified. Despite the foamy cytoplasm of some apocrine carcinomas and the existence of lipid in the normal apocrine(More)
