Whether circulating tumor cells (CTCs) can be used as an indicator of treatment response in breast cancer (BC) needs to be clarified. We addressed this issue by a meta-analysis. PubMed, EMBase and Cochrane library databases were searched in June 2016. Effect measures were estimated as pooled risk ratio (RR), odds ratio (OR) or mean difference by fixed- or random-effect models, according to heterogeneity of included studies. In total, 50 studies with 6712 patients were recruited. Overall analysis showed that there was a significant reduction of CTC-positive rate (RR = 0...

PURPOSE: Denosumab has been proven to reduce fracture risk in breast cancer (BC) women under aromatase inhibitors (AIs). Quantitative ultrasound (QUS) provides information on the structure and elastic properties of bone. Our aim was to assess bone health by phalangeal QUS and by dual-energy X-ray absorptiometry (DXA), and to evaluate bone turnover in AIs-treated BC women receiving denosumab. METHODS: 35 Postmenopausal BC women on AIs were recruited (mean age 61...

OBJECTIVE: Preventive breast surgery and MRI screening are offered to unaffected BRCA mutation carriers. The clinical benefit of these two modalities has not been evaluated among mutation carriers with a history of ovarian cancer. Thus, we sought to determine whether or not BRCA mutation carriers with ovarian cancer would benefit from preventive mastectomy or from MRI screening. METHODS: First, the annual mortality rate for ovarian cancer patients was estimated for a cohort of 178 BRCA mutation carriers from Ontario, Canada...

Cardiac irradiation increases the risk of coronary artery disease in patients with left-sided breast cancer. Techniques exist to reduce cardiac irradiation, but the optimum technique depends on individual patient anatomy and physiology. We investigated the correlation of delta heart volume in field (dHVIF) and sternal excursion with dose sparing in heart and left anterior descending artery (LAD) to develop quantitative predictive models for expected dose to heart and LAD. A treatment planning study was performed on 97 left-breast cancer patients who underwent whole breast radiotherapy (prescription dose = 50 Gy) under deep inspiratory breath hold (DIBH)...

BACKGROUND: In the U.S., breast cancer accounts for more cancer deaths in women than any site other than lung cancer. Based upon attributable risks, about 30-35% of breast cancers could potentially be prevented by addressing obesity, physical inactivity, increased alcohol consumption, and carcinogenic exposures such as hormone replacement therapy (HRT). We need methods of reducing women's risks of this disease that are attractive and easy to use, widely accessible to diverse women, and able to be easily amended to account for new research...

BACKGROUND: Owing to highly conformed dose distribution, intensity modulated radiation therapy (IMRT) has the potential to improve treatment results of radiotherapy (RT). Postoperative RT is a standard adjuvant treatment in conservative treatment of breast cancer (BC). The aim of this review is to analyze available evidence from randomized controlled trials (RCTs) on IMRT in BC, particularly in terms of reduction of side effects. METHODS: A literature search of the bibliographic database PubMed, from January 1990 through November 2016, was performed...

OBJECTIVES: Mammographic density (MD) is an independent risk factor for breast cancer and may have a future role for stratified screening. Automated software can estimate MD but the relationship between breast thickness reduction and MD is not fully understood. Our aim is to develop a deformable breast phantom to assess automated density software and the impact of breast thickness reduction on MD. METHODS: Several different configurations of poly vinyl alcohol (PVAL) phantoms were created...

Historically, ovarian ablation (OA) was used as therapy for women with recurrent hormone-receptor-positive (HRP) premenopausal breast cancer. With the publication of the SOFT (Suppression of Ovarian Function Trial) and TEXT (Tamoxifen and Exemestane Trial) randomized trials, there is considerable interest in OA as an adjuvant treatment, either in combination with tamoxifen or an aromatase inhibitor (AI). Thus, we have reviewed current guidelines and key studies on this important topic and have highlighted the relevant biological and pharmacological aspects of the various endocrine therapies...

BACKGROUND: Proton beam therapy represents a promising modality for left-side breast cancer (BC) treatment, but concerns have been raised about skin toxicity and poor cosmesis. The aim of this study is to apply skin normal tissue complication probability (NTCP) model for intensity modulated proton therapy (IMPT) optimization in left-side BC. MATERIAL AND METHODS: Ten left-side BC patients undergoing photon irradiation after breast-conserving surgery were randomly selected from our clinical database...

Prior to the unexpected early termination of the Women's Health Initiative (WHI) trial of continuous conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA), the prevailing view was that hormone replacement therapy (HRT) was a low-risk intervention with immediate value for symptom relief in recently menopausal women, and that it probably conferred long-term protection against the major chronic diseases that affect women after menopause. Rather than replicating prior studies, the WHI was designed to test whether the beneficial associations consistently seen in women starting HRT near menopause would be found in women well beyond menopause...

BACKGROUND: Survival rates for women with a diagnosis of breast cancer continue to improve. However, some women may experience physical, psychological and emotional effects post diagnosis, throughout treatment and beyond. Support groups can provide opportunities for people to share their experiences and learn from others. As the number of online support groups increases, more and more women with breast cancer will likely access them. OBJECTIVES: To assess effects of online support groups on the emotional distress, uncertainty, anxiety, depression and quality of life (QoL) of women with breast cancer...

Crown-like structures (CLS), composed of macrophages surrounding dead or dying adipocytes, are a histologic hallmark of the pro-inflammatory process by which adipose tissue contributes to the increased risk and worse prognosis of breast cancer in obese, post menopausal patients. In this issue of Cancer Prevention Research, Iyengar et al report the intriguing finding that CLS, can be identified in a significant proportion of normal BMI women undergoing mastectomy for breast cancer risk reduction or therapy (1)...

Monitoring screening mammography effects in small areas is often limited by small numbers of deaths and delayed effects. We developed a risk score for breast cancer death to circumvent these limitations. Screening, if effective, would increase post-diagnostic survivals through lead-time and related effects, as well as mortality reductions. Linked cancer and BreastScreen data at four hospitals (n = 2,039) were used to investigate whether screened cases had higher recorded survivals in 13 small areas, using breast cancer deaths as the outcome (M1), and a risk of death score derived from TNM stage, grade, histology type, hormone receptor status, and related variables (M2)...

BACKGROUND: Women with small nonpalpable breast tumours have an excellent prognosis. The benefit of radiotherapy in this group of low-risk women is unknown. METHODS: A cohort of 1595 women with stages i-iii invasive breast cancer treated with breast-conserving surgery were followed for local recurrence. Using t-tests, baseline demographic data and tumour characteristics were compared for the women who had palpable (n = 1023) and mammography-detected (n = 572) breast cancers...

Obesity is associated with breast white adipose tissue (WAT) inflammation, elevated levels of the estrogen biosynthetic enzyme, aromatase, and systemic changes that have been linked to the pathogenesis of breast cancer. Here, we determined whether metabolic obesity, including changes in breast biology and systemic effects, occurs in a subset of women with normal body mass index (BMI). Breast WAT and fasting blood were collected from 72 women with normal BMI (<25 kg/m(2)) undergoing mastectomy for breast cancer risk reduction or treatment...

Recently, there has been an increase in the rate of contralateral prophylactic mastectomies (CPM) as a therapy for breast cancer. The CPM is performed to achieve a reduction in the risk of developing asecond breast cancer. However, evidence is lacking for beneficial survival outcomes after a CPM in patients without a gene mutation, and complications of surgery are inevitable. Currently there are no evidence-based clinical practice guidelines available for clinicians to decide upon the right treatment for patients without a gene mutation...

REVIEW
Lesley Andrews, David G Mutch
Mutations in BRCA1 and BRCA2 account for hereditary breast and ovarian cancer syndrome in a majority of families and 14% of epithelial ovarian cancer cases. Despite next-generation sequencing, other identified genes (Lynch Syndrome, RAD51C, RAD51D, and BRIP1) account for only a small proportion of cases. The risk of ovarian cancer by age 70 is approximately 40% for BRCA1 and 18% for BRCA2. Most of these cancers are high-grade serous cancers that predominantly arise in the fimbriae of the fallopian tube. Ovarian screening does not improve outcomes, so women at high risk are recommended to undergo risk-reducing salpingo-oophorectomy around the age of 40, followed by hormone replacement therapy (HRT)...

PURPOSE OF REVIEW: Many studies have examined the effects of adjuvant bisphosphonates on long-term breast cancer outcomes. However, results have been inconsistent. Here, we review the evidence for their role in early breast cancer. RECENT FINDINGS: In a recent meta-analysis, no significant decreases in recurrence or breast cancer mortality were observed in the overall population. In postmenopausal women, statistically significant, but modest, reductions in distant recurrence were observed, driven by decreased bone recurrence...

The pioneering Royal Marsden Tamoxifen Prevention Trial recruited 2,471 eligible high-risk women to be randomized to either placebo or tamoxifen (20 mg daily) for 8 years. Breast cancer incidence was evaluated at a median of 18.4 years from the start of the study. There was a 32% reduction in estrogen/progesterone receptor (ER/PR)-positive breast cancers after tamoxifen treatment finished. Translational research, to study "the good, the bad, and the ugly of tamoxifen" in the 1980s, subsequently ensured women's safety from possible increases in osteoperosis, coronary heart disease, and endometrial cancer...
