Environmental exposures and/or genetic background in Japanese population, which might contribute to the relatively low breast cancer incidence rates in Japan, have not been clarified in detail. Folate plays an essential role in DNA methylation and synthesis, and thus may be involved in the development of breast cancer. Functional polymorphisms in genes(More)
Endocrine therapy is the most important treatment of choice for estrogen receptor (ER)-positive breast cancer. Potential mechanisms for resistance to endocrine therapy involve ER-coregulatory proteins and cross-talk between ER and other growth factor-signaling networks. However, the factors and pathways responsible for endocrine therapy resistance,(More)
BACKGROUND Patients with de novo stage IV and relapsed breast cancer are often treated with the same strategy. However, survival differences have recently been reported between the disease types. PURPOSE The aim of this study was to compare outcomes between de novo stage IV disease and relapsed disease and to discuss any differences in prognostic factors(More)
The expression of estrogen receptor (ER) and bcl-2(Bcl-2), an apoptosis protective oncogene, in normal andcancerous breast duct epithelia was immunohistochemically examined infresh frozen tumor tissues from 142 Japanese breastcancer patients. The clinico-pathological characteristics and the diseasefree survival of the patients were analyzed. Theexpression(More)
The possible association of high soy food consumption with low incidence of breast cancer in Asian countries has been widely investigated, but findings from epidemiologic studies have been inconsistent. Breast cancers defined by receptor status, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) may have(More)
OBJECTIVE Although the fear of recurrence is a major concern among breast cancer survivors after their surgery, there are no instruments to evaluate their distress in Japan. This study examines the psychometric properties of the Japanese version of the concerns about recurrence scale, which was originally developed in the USA. METHODS The forward and(More)
Although fear of recurrence is a major concern among breast cancer survivors after surgery, no standard strategies exist that alleviate their distress. This study examined the association of patients’ problem-solving skills and fear of recurrence and psychological distress among breast cancer survivors. Randomly selected, ambulatory, female patients with(More)
Serum CA15-3, CEA, and BCA225 concentrations were determined in 98 patients with advanced or recurrent breast cancer in an attempt to correlate elevation with clinical status. The rate of serum positivity was 68.4% (67/98), 55.1% (54/98), and 43.9% (43/98) for CA15-3, CEA, and BCA225, respectively. After a 4 weeksinterval, a 20% change of tumor marker(More)
We herein report a case of second sentinel lymph node biopsy (SLNB). A 57-year-old woman underwent breast-conserving surgery including axillary clearance at Aichi Cancer Center on October 20, 2003. Recurrent tumor in the conserved breast was diagnosed in March 2006. She received SLNB using radioactive tracer. Preoperative lymphoscintigraphy detected 2(More)
Epidermal growth factor receptor (EGFr) levels were analyzed in 140 primary breast cancer specimens by immunohistochemical assay (ICA), competitive binding assay (BA), or enzyme immunoassay (EIA). Thirtynine of 118 specimens (33.1%) were scored as positive by ICA, 30 of 116 (25.9%: cut-off level 10 fmol/mg protein) by BA, and 31 of 80 (38.9%: cut-off level(More)
