BRCAsearch: written pre-test information and BRCA1/2 germline mutation testing in unselected patients with newly diagnosed breast cancer

Purpose To evaluate a simplified method of pre-test information and germline BRCA1/2 mutation testing. Methods In a prospective, single-arm study, comprehensive BRCA1/2 testing was offered to unselected patients with newly diagnosed breast cancer at three hospitals in south Sweden (BRCAsearch, ClinicalTrials.gov Identifier: NCT02557776). Pre-test information was provided by a ...

Routine treatment and outcome of breast cancer in younger versus elderly patients: results from the SENORA project of the prospective German TMK cohort study

Purpose There is an ongoing discussion about ‘undertreatment’ of breast cancer in elderly patients. Due to low accrual into clinical trials, level 1 evidence is scarce. We report prospective data of elderly patients with breast cancer treated by medical oncologists in Germany. Methods The SENORA project within the prospective cohort study TMK (Tumour Registry Breast Cancer) was ...

Molecular profile of atypical hyperplasia of the breast

Purpose Atypical ductal and atypical lobular hyperplasia (AH) of the breast are important proliferative lesions which are associated with a significantly increased risk for breast cancer. The breast cancer which develops in association with AH may occur synchronously, representing local progression, or metachronously at a later date in either the ipsilateral or contralateral ...

Does levonorgestrel-releasing intrauterine system increase breast cancer risk in peri-menopausal women? An HMO perspective

Purpose To evaluate the association between levonorgestrel-releasing intrauterine system (LNG-IUS) use and breast cancer (BC) risk. Methods A cohort of all Maccabi Healthcare Services (MHS) female members aged 40–50 years between 1/2003 and 12/2013 was used to identify LNG-IUS users as “cases,” and 2 age-matched non-users as “controls.” Exclusion criteria included: prior BC ...

Severe depression more common in patients with ductal carcinoma in situ than early-stage invasive breast cancer patients

Purpose Ductal carcinoma in situ (DCIS) is associated with an excellent prognosis; historical studies have shown similar levels of psychological distress in patients with DCIS and with early-stage invasive breast cancer (early-IBC). It is suggested that these results might have led to better patient education about prognosis after DCIS. This study reports the current levels of ...

Multidimensional phenotyping of breast cancer cell lines to guide preclinical research

Purpose Cell lines are extremely useful tools in breast cancer research. Their key benefits include a high degree of control over experimental variables and reproducibility. However, the advantages must be balanced against the limitations of modelling such a complex disease in vitro. Informed selection of cell line(s) for a given experiment now requires essential knowledge about ...

Non-visualized sentinel nodes in breast cancer patients; prevalence, risk factors, and prognosis

Background Evidence and consensus is lacking in international guidelines regarding axillary treatment recommendations for patients in whom a sentinel lymph node (SLN) cannot be visualized (non-vSLN) during the sentinel node procedure. In this study we aimed to determine the prevalence of non-vSLNs in a Dutch population of breast cancer patients and to examine predictors and ...

Survival and level of care among breast cancer patients with brain metastases treated with whole brain radiotherapy

Purpose The benefit of whole brain radiotherapy (WBRT) for late stage breast cancer patients with brain metastases has been questioned. In this study we evaluated survival and level of care (hospital or home) following WBRT in a population-based cohort by personal and tumor characteristics. Methods We identified 241 consecutive patients with breast cancer and brain metastases ...

Utilization of bioimpedance spectroscopy in the prevention of chronic breast cancer-related lymphedema

Background This analysis was performed to assess the impact of early intervention following prospective surveillance using bioimpedance spectroscopy (BIS) to detect and manage breast cancer-related lymphedema (BCRL). Methods From 8/2010 to 12/2016, 206 consecutive patients were evaluated with BIS. The protocol included pre-operative assessment with L-Dex as well as post-operative ...

Molecular characterization and heterogeneity of circulating tumor cells in breast cancer

Introduction This study analyzes peripheral blood samples from breast cancer (BC) patients. CTCs from peripheral blood were enriched by size-based separation and were then cultivated in vitro. The primary aim of this study was to demonstrate the antigen independent CTC separation method with high CTC recovery. Subsequently, CTCs enriched several times during the treatment were ...

NanoString-based breast cancer risk prediction for women with sclerosing adenosis

Purpose Sclerosing adenosis (SA), found in ¼ of benign breast disease (BBD) biopsies, is a histological feature characterized by lobulocentric proliferation of acini and stromal fibrosis and confers a two-fold increase in breast cancer risk compared to women in the general population. We evaluated a NanoString-based gene expression assay to model breast cancer risk using RNA ...

IPET study: an FLT-PET window study to assess the activity of the steroid sulfatase inhibitor irosustat in early breast cancer

Background Steroid sulfatase (STS) is involved in oestrogen biosynthesis and irosustat is a first generation, irreversible steroid sulfatase inhibitor. A pre-surgical window-of-opportunity study with irosustat was undertaken in estrogen receptor-positive (ER+) breast cancer to assess the effect of irosustat on tumour cell proliferation as measured by 3′-deoxy-3′-[18F] ...

Tamoxifen therapy benefit for patients with 70-gene signature high and low risk

Background Breast cancer molecular prognostic tools that predict recurrence risk have mainly been established on endocrine-treated patients and thus are not optimal for the evaluation of benefit from endocrine therapy. The Stockholm tamoxifen (STO-3) trial which randomized postmenopausal node-negative patients to 2-year tamoxifen (followed by an optional randomization for an ...

Prognostic and predictive importance of the estrogen receptor coactivator AIB1 in a randomized trial comparing adjuvant letrozole and tamoxifen therapy in postmenopausal breast cancer: the Danish cohort of BIG 1-98

Purpose To evaluate the estrogen receptor coactivator amplified in breast cancer 1 (AIB1) as a prognostic marker, as well as a predictive marker for response to adjuvant tamoxifen and/or aromatase inhibitors, in early estrogen receptor-positive breast cancer. Method AIB1 was analyzed with immunohistochemistry in tissue microarrays of the Danish subcohort (N = 1396) of the ...

Cross-cultural comparison of breast cancer patients’ Quality of Life in the Netherlands and Japan

Purpose Cultural differences are hypothesized to influence patients’ Quality of Life (QoL) reports. However, there is a lack of empirical cross-cultural studies comparing QoL of patients with cancer. This study aims to compare QoL of women with breast cancer in the Netherlands and Japan, and to investigate the association of QoL with sociodemographic, clinical, and psychological ...
