BACKGROUND The clinical features of ipsilateral breast tumor recurrence (IBTR) after breast conserving therapy (BCT) for early stage breast cancer were analyzed from long-term follow-up of BCT in Japan. The purpose of this study was to clarify risk factors of IBTR and the impact of IBTR on development of distant metastases in this ethnic group. METHODS(More)
PURPOSE Metronomic combination chemotherapy with the oral fluoropyrimidine doxifluridine/5'-deoxy-5-fluorouridine (5 -DFUR) and oral cyclophosphamide (C) showed promising efficacy in a single-arm study. The oral fluoropyrimidine capecitabine was designed to deliver 5-fluorouracil preferentially to tumors, potentially improving efficacy over doxifluridine.(More)
UNLABELLED The feasibility and efficacy of adriamycin or epirubicin in combination with cyclophosphamide followed by weekly paclitaxel (AC/EC-weekly PAC) as adjuvant chemotherapy for breast cancer was investigated. PATIENTS AND METHODS Node-positive breast cancer was treated with AC/ EC-weekly PAC, namely AC at 60/600 mg/m(2) or EC at 90/600 mg/m(2) x4 at(More)
PURPOSE The primary aim of this study was to compare the effectiveness of oral uracil-tegafur (UFT) with that of classical cyclophosphamide, methotrexate, and fluorouracil (CMF) given as postoperative adjuvant treatment to women with node-negative, high-risk breast cancer. PATIENTS AND METHODS Women with node-negative, high-risk breast cancer were(More)
Breast carcinoma is a complex disease characterized by accumulation of multiple genetic alterations, and the understanding of the molecular basis of mammary tumorigenesis is still incomplete. In this study we analyzed gene-expression profiles of 81 surgical specimens of 12 ductal carcinoma in situ (DCIS) and 69 invasive ductal carcinoma (IDC). After(More)
Liver metastasis of breast cancer is considered a generalized disease, and surgical treatment is rarely discussed. Thirty-four patients who underwent 35 hepatectomies for liver metastases of breast cancer between 1985 and 2003 were analyzed. The median interval between the breast surgery and relapse in the liver was 1.9 years (0-20 years). The liver was the(More)
We retrospectively evaluated whether a surgical strategy benefits patients with operable lung metastasis of breast cancer. Between 1960 and 2000, 90 patients (mean age 55.1; range 32-77) with lung metastasis (79 solitary, 11 multiple) underwent surgery as follows: wedge resection (n = 10), segmental resection (n = 11), lobectomy (n = 68) and pneumonectomy(More)
BACKGROUND A multicenter, phase II study was conducted to evaluate the efficacy and safety of the Japanese intermittent 4-week regimen of capecitabine in patients with advanced/metastatic breast cancer. METHODS Fifty patients who had received no more than one prior chemotherapy regimen for advanced/metastatic disease were enrolled from 23 centers and(More)
BACKGROUND Breast cancer has emerged as one of the most frequent malignancies among Japanese women; however, the long-term survival of Japanese breast cancer patients is uncertain. METHODS We analyzed the chronological changes in the clinical and pathological characteristics, treatment procedures and the long-term prognosis of 15 416 Japanese women with(More)
BACKGROUND Ipsilateral breast tumor recurrences (IBTR) after breast-conserving treatment include two different entities: true recurrence (TR) thought to occur when residual cancer cells grow gradually to detectable size and new primary (NP) thought to be de novo cancer independently arising in the preserved breast. The patients with ipsilateral breast tumor(More)
