PURPOSE Detection of sentinel lymph node (SLN) metastasis in breast cancer patients has conventionally been determined by intraoperative histopathologic examination of frozen sections followed by definitive postoperative examination of permanent sections. The purpose of this study is to develop a more efficient method for intraoperative detection of lymph(More)
The O 6-methylguanine-DNA methyltransferase (MGMT) protein protects cells from alkylating agents by removing alkyl groups from the O 6-position of guanine. However, its effect on DNA damage induced by cyclophospha-mide (CPM) is unclear. The present study investigated whether MGMT expression was correlated with prognosis in patients with breast cancer that(More)
PURPOSE Accurate assessment of metastasis in sentinel lymph nodes (SLN) of breast cancer is important but involves a heavy workload for the pathologist. We conducted a multicenter clinical trial in Japan to evaluate a new automated assay system for cytokeratin 19 mRNA, the one-step nucleic acid amplification (OSNA) assay (Sysmex), to detect lymph node(More)
Lifestyle factors, including food and nutrition, physical activity, body composition and reproductive factors, and single nucleotide polymorphisms (SNPs) are associated with breast cancer risk, but few studies of these factors have been performed in the Japanese population. Thus, the goals of this study were to validate the association between reported SNPs(More)
p21 (WAF1/CIP1) protein expression in various thyroid tissues, including thyroid carcinoma, was studied by means of immunohistochemistry using anti-p21 monoclonal antibody. Normal follicles and hyperplasias rarely expressed p21, whereas immunohistochemically positive cells were also too rarely found in follicular adenomas to justify these cases being(More)
BACKGROUND We evaluated the safety, maximum-tolerated dose (MTD), pharmacokinetics, recommended dose for phase II (P2RD), and preliminary anticancer activity of a combination eribulin and S-1 therapeutic in metastatic breast cancer patients pretreated with anthracycline and taxane. METHOD Patients aged 20-74 years were recruited. In level 1, patients(More)
Eribulin is a recently approved new therapeutic option for patients with metastatic breast cancer. According to several reports, eribulin has limited ability to cross the blood brain barrier. Recently, capecitabine and eribulin have been recognized as drugs with similar application for patients with advanced breast cancer. Although there have been several(More)
We conducted a phase I study of a weekly nab-paclitaxel and S-1 combination therapy in patients with human epidermal growth factor receptor type 2-negative metastatic breast cancer. The primary objective was to estimate the maximum tolerated and recommended doses. Each treatment was repeated every 21 days. Levels 1, 2a, 2b, and 3 were set depending on the(More)
PURPOSE The purpose of this study was to evaluate preferences for oral versus intravenous adjuvant chemotherapy among early breast cancer patients (UMIN-CTR number UMIN000004696). PATIENTS AND METHODS Eighty-two postmenopausal women with estrogen receptor-positive, human epidermal growth-factor receptor 2-negative breast cancer who had completed adjuvant(More)
Aldehyde dehydrogenase 1 (ALDH1) is a cancer stem cell (CSC) marker that is easily evaluable. The expression and clinical significance of ALDH1 in ipsilateral breast tumor recurrence (IBTR) has yet to be investigated. In the present study, the expression profile of ALDH1 and its correlation with prognosis in IBTR tissues was examined. Patients with IBTR(More)
