OBJECTIVE: To evaluate the effects of S-1, an orally administered 5-FU agent, versus taxane on patient-reported outcomes (PROs) in the SELECT BC trial. METHODS: Patients with HER2-negative and endocrine treatment-resistant breast cancer with metastasis or recurrence after surgery were randomly assigned to receive first-line taxane or S-1. PROs (secondary endpoint) were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and Patient Neurotoxicity Questionnaire (PNQ) at baseline and at 3, 6, and 12 months...

BACKGROUND: Approximately 70% of all breast cancers express the estrogen receptor, and are regulated by estrogen. While the ovaries are the primary source of estrogen in premenopausal women, most breast cancer is diagnosed following menopause, when systemic levels of this hormone decline. Estrogen production from androgen precursors is catalyzed by the aromatase enzyme. Although aromatase expression and local estrogen production in breast adipose tissue have been implicated in the development of primary breast cancer, the source of estrogen involved in the regulation of estrogen receptor-positive (ER+) metastatic breast cancer progression is less clear...

BACKGROUND: In oncology, hypnosis has been used for pain relief in metastatic patients but rarely for induction of anesthesia. MATERIAL AND METHOD: Between January 2010 and October 2015, 300 patients from our Breast Clinic (Cliniques universitaires Saint-Luc, Université catholique de Louvain) were included in an observational, non-randomized study approved by our local ethics committee (ClinicalTrials.gov - NCT03003611). The hypothesis of our study was that hypnosis intervention could decrease side effects of breast surgery...

BACKGROUND: The 21-gene recurrence score (RS) predicts outcome and benefit from adjuvant chemotherapy benefit in breast cancer patients treated with adjuvant endocrine therapy. In the NSABP B-28 study, we evaluated the 21-gene RS for its prognostic impact and its ability to predict benefit from paclitaxel (P) in node-positive, estrogen receptor-positive (ER+) breast cancer patients treated with adjuvant chemotherapy plus tamoxifen. METHODS: The B-28 trial compared doxorubicin/cyclophosphamide (AC) with AC followed by P in 3060 patients...

Sexual dysfunction is a prevalent concern among breast cancer survivors, and is often multifactorial in nature. Causes can be both physiologic and psychological; chemotherapy, endocrine therapy, and disfigurement from breast cancer surgery can all play a role. Sexual dysfunction can have a profound impact on quality of life and relationships and can also impact adherence to endocrine therapy. However, it can be a difficult topic for both patients and providers to bring up, and as a result, it is often inadequately addressed...

BACKGROUND: The response to neoadjuvant chemotherapy (NAC) varies by estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2) statuses, with responses being lower in ER-positive, HER2-negative tumors as compared with ER-negative, HER2-positive or triple-negative tumors. Neoadjuvant endocrine therapy (NET) is an attractive alternative to NAC for ER-positive, HER2-negative cancer. However, a prior trial comparing NET with standard NAC in ER-positive tumor showed that the difference of response was not significant...

BACKGROUND: Although treatment of ductal carcinoma in situ (DCIS) is controversial, national guidelines recommend considering endocrine therapy for women with estrogen receptor- (ER-) positive DCIS or those undergoing breast conserving surgery (BCS) without radiation. We evaluated uptake and predictors of endocrine therapy use among older women with DCIS. METHODS: In the SEER-Medicare database, we identified women aged 65+ years diagnosed with DCIS during 2007-2011...

Mucinous breast carcinoma (MBC) is relatively rare, accounting for <10% of all breast cancers in women. These tumors are usually slow-growing and exhibit less aggressive characteristics compared with other types of breast cancer. Between 1989 and 2016, 55 patients underwent surgery for MBC at the Shiga Medical Center for Adults (Moriyama, Japan). The 10-year disease-free survival (DFS) and overall survival rates were 94.5 and 100.0%, respectively. Specifically, the 10-year DFS rates of pure MBC (PMBC) and mixed MBC were 97...

BACKGROUND: The current study was conducted to examine the association between ipsilateral breast tumor recurrence (IBTR) and the timing of radiotherapy (RT) in women with ductal carcinoma in situ (DCIS) undergoing breast-conserving surgery (BCS). METHODS: Women with DCIS who were treated with BCS and RT from 1980 through 2010 were identified from a prospectively maintained database. IBTR rates, measured from the time of RT completion, were compared between those who initiated RT ≤8 weeks, >8 to 12 weeks, and >12 weeks after the completion of surgery...

AIM: The optimal treatment of breast cancer for extremely elderly patients (aged ≥ 80 years) is debatable. With an aging population, management of this group of patients will be increasingly common. This study aims to compare the survival outcomes of extremely elderly patients against younger ones, following different treatment modalities within each stage. The differences in treatment patterns across different stages have also been examined. METHODS: Female Singapore Citizens and Permanent Residents diagnosed with breast cancer from 2003 to 2014 were identified from the Singapore Cancer Registry...

INTRODUCTION: Endocrine therapy of breast cancer, which either deprives cancer tissue of estrogen or prevents estrogen pathway signaling, is the most common treatment after surgery and radiotherapy. We have previously shown for the estrogen-responsive MCF-7 cell line that exposure to tamoxifen, or deprivation of estrogen, leads initially to inhibition of cell proliferation, followed after several months by the emergence of resistant sub-lines that are phenotypically different from the parental line...

Recent published guidelines suggest that adequate margins for DCIS should be ≥ 2 mm after breast conserving surgery followed by radiotherapy (RT). Many groups now use this guideline as an absolute indication for additional surgery. This article describes detailed multidisciplinary practices including extensive preoperative/intraoperative pathologic/histologic image-guided assessment of margins, offering some patients with small low/intermediate grade DCIS no RT, the use/magnitude of radiation boost tailoring to margin width, and endocrine therapy for ER-positive DCIS...

BACKGROUND: Neoadjuvant systemic therapy (NAST) can be used to treat breast cancer. Pathologic complete response (pCR) is a surrogate marker for improved survival. This study examined response in the breast and axilla to NAST and identified features associated with pCR. METHODS: Patients undergoing NAST and surgery between January 2012 and June 2016 by surgeons at Westmead Breast Cancer Institute were identified. Patients with inflammatory or metastatic disease were excluded...

The prevalence of ductal carcinoma in situ (DCIS) of the breast has increased substantially after the introduction of breast cancer screening programs, although the clinical effects of early DCIS detection and treatment remain unclear. The standard treatment for DCIS has involved local breast-conserving surgery (BCS) followed by radiotherapy (RT) or total mastectomy with/without endocrine therapy, and the choice of local treatment is not usually based on clinicopathologic or biological factors. However, we have investigated the effectiveness of local treatment using breast surgery and RT using Surveillance, Epidemiology, and End Results data, and found that the effectiveness of breast surgery was modified by the nuclear grade...

OBJECTIVES: Medical records are considered the gold standard for accurate treatment information. However, treatment data are increasingly obtained from questionnaires. It can be questioned whether self-reported treatment data are reliable, particularly because patients have to process a lot of information during their diagnosis and treatment process. The present study assesses the reliability of self-reported treatment data compared with medical records. METHODS: All patients with stage I, II, and III breast cancer (n = 606) in 5 hospitals in the west of the Netherlands were invited to complete a questionnaire 9 to 18 months after surgery...

BACKGROUND: Elderly patients are more likely to have oestrogen receptor positive cancers that can be treated without surgery with primary endocrine therapy (PET). Few studies have sought to identify predictors of failure of PET and so the aim of this study was to evaluate treatment failures in elderly breast cancer patients treated with PET and to determine predictors of failure. METHODS: A retrospective observational study was performed on consecutive patients with ER-positive early stage breast cancer treated with PET between 2005 and 2015 in the three breast units in the North East of England...
