G protein-coupled estrogen receptor (GPER) signaling is activated in triple-negative breast cancer (TNBC); however, the detailed mechanisms of its regulation remain unclear. The present study aimed to elucidate the molecular mechanisms involved in GPER activation in TNBC. In MDA-MB-231 cells, a TNBC cell line, NHERF1 interaction with GPER was verified by co-immunoprecipitation and immunofluorescent staining assays. Overexpression of NHERF1 in MDA-MB-231 cells inhibited GPER-mediated proliferation and phosphorylation of ERK1/2 and Akt...

PURPOSE: HER2-amplified breast cancer (BC) has a poor prognosis. The combination of trastuzumab with chemotherapy in the adjuvant setting decreases recurrence and improves overall survival in HER2-positive BC. However, the role of adjuvant treatment in patients with HER2-amplified small BC without lymph node involvement is still under debate. The purpose of this study was to investigate the safety of adjuvant paclitaxel and trastuzumab (APT) in this group of patients. METHODS: A total of 87 operated early BC patients without lymph node involvement (N0) were treated with APT for 12 weeks followed by trastuzumab alone for a total of 9 months...

Our aim is to investigate whether or not the breast cancer metastasis suppressor 1 ( BRMS1 ) gene expression is directly linked to clinico-pathological features of breast cancer. Following a stringent inclusion and exclusion criteria, case-control studies with associations between BRMS1 and breast cancer were selected from articles obtained by way of searches conducted through an electronic database. All statistical analyses were performed with Stata 12.0 (Stata Corp, College Station, TX, USA). Ultimately, 1,263 patients with breast cancer were found in a meta-analysis retrieved from a total that included 12 studies...

Introduction: Inflammatory breast cancer (IBC) is a rare aggressive form of breast cancer. It is well known that the long-term survival and progression-free survival of IBC are worse than that of non-IBC. We report the long term outcomes of patients with IBC and non-IBC who had undergone high-dose chemotherapy (HDC) with autologous hematopoietic cell transplantation (AHCT). Methods: All 3387 patients with IBC or non-IBC who underwent HDC with AHCT between1990-2002 and registered with CIBMTR were included in this analysis...

OBJECTIVES: The survival rate of cancer patients has exceeded 60%. Although cancer survivors may die of other diseases except cancer, the health management system including chronic disease prevention-management for cancer survivors, has not been established in the diverse aspects. Therefore, services according to care pathway of cancer patients need to be provided through a support system based on a platform concept that can be used to meet patient needs in various ways. METHODS: A sample cohort database (2002-2010) of approximately 1 million persons-2% of the whole nation (50 million)-was used to estimate cancer survivors through a principal care pathway for cancer management...

REVIEW
Lisa A Newman
Treatment of early-stage invasive breast cancer with breast-conserving surgery plus radiation therapy (RT) yields overall survival outcomes equivalent to those achieved with mastectomy. Further, breast-conserving surgery is endorsed by the National Comprehensive Cancer Network as being supported by the highest-level, category 1 evidence. Advances in pathologic evaluation, management of multiple tumors, oncoplastic lumpectomy techniques, neoadjuvant chemotherapy, and hypofractionated RT can expand the pool of patients eligible for breast-conserving surgery...

OBJECTIVE: Sleep can affect quality of life (QoL) during cancer survivorship, and symptoms related to poor sleep can be exacerbated. We examined the prevalence, severity, and nature of subjective sleep complaints in women surviving stage I-III breast cancer who were 1-10 years posttreatment. We also examined the demographic, medical, physical, and psychosocial correlates of poor sleep in these women in order to identify the subgroups that may be most in need of intervention. METHOD: A total of 200 patients at a comprehensive cancer center who were 1-10 years posttreatment for primary stage I-III breast cancer with no evidence of disease at the time of enrollment completed a battery of questionnaires on demographics, sleep, physical symptoms, mood, cancer-specific fears, and QoL...

Cancer staging and grading are used to predict the clinical behavior of malignancies, establish appropriate therapies, and facilitate exchange of precise information between clinicians. The internationally accepted criterion for cancer staging, the tumor-node-metastasis (TNM) system, includes: (1) tumor size and local growth (T), (2) extent of lymph node metastases (N), and (3) occurrence of distant metastases (M). Clinical stage is established before initiation of therapy and is determined by physical examination, laboratory findings, and imaging studies...

PURPOSE: Optimal duration of adjuvant chemotherapy in the treatment of early-stage breast cancer remained to be investigated rigorously for the standard regimens in widespread use in North America (doxorubicin/cyclophosphamide, AC) and Europe (5-fluorouracil/epirubicin/cyclophosphamide, FEC). Whether six cycles of FEC 100 present an advantage, or not, compared with only four cycles was tested directly in a phase III prospective multicentre trial. PATIENTS AND METHODS: Between 2002 and 2006, 1515 women between 18 and 65°years of age, with node negative N(-) high-risk early-stage breast cancer, were included in the study following breast surgery and axillary lymph node dissection or procedure by sentinel node technique...
