BACKGROUND: Young mothers (age 14-24 years), who are often low income, are less likely than other mothers to breastfeed for 6 months. They also are more likely to be diagnosed with aggressive forms of breast cancer; breastfeeding significantly reduces this risk. While adolescent breastfeeding has been investigated from the perspective of the individual, the social ecological model recognizes the influence of factors at multiple levels. RESEARCH AIM: The aim was to identify social and structural barriers to and motivators of breastfeeding that young mothers may encounter...

Women with BRCA mutations, who choose to decline or defer risk-reducing mastectomy, require a highly sensitive breast screening regimen they can begin by age 25 or 30. Meta-analysis of multiple observational studies, in which both mammography and magnetic resonance imaging (MRI) were performed annually, demonstrated a combined sensitivity of 94% for MRI plus mammography compared to 39% for mammography alone. There was negligible benefit from adding screening ultrasound or clinical breast examination to the other two modalities...

OBJECTIVE: Adjuvant Endocrine Therapy (AET) significantly reduces risk of breast cancer recurrence in those patients whose tumor tests hormone (estrogen and/or progesterone) receptor positive. Many who are prescribed AET do not adhere adequately. Studies have sought to examine the effects of interventions to enhance patients' AET adherence, with strikingly mixed results. In order to reconcile a disparate literature, this paper aims to (1) quantitatively review the aggregate effect of interventions designed to optimize AET adherence within the current literature; and (2)meta-analyze these effects across studies' by intervention design...

Background: The risk of hormone positive breast cancer extends beyond 5 years. Extended duration of tamoxifen to 10 years has been shown to improve overall survival (OS) and disease-free survival (DFS). In post-menopausal women aromatase inhibitor (AI) is the gold standard for adjuvant endocrine therapy. Several randomized controlled trials (RCTs) showed benefit with extending the duration of AIs in post-menopausal women. However, the duration and the overall benefit is still controversial...

Drug resistance and cancer cells metastasis have been the leading causes of chemotherapy failure and cancer-associated death in breast cancer patients. In present, various active molecules either exhibiting novel mechanism of action such as inducing autophagy or inhibiting metastasis have been developed to address these problems. However, the compounds exhibiting such dual functions have rarely been described. Previous work in our group showed that TSA, as a synthetic analog of asperphenamate, induced autophagic cell death in breast cancer cells instead of apoptosis...

The management of ductal carcinoma in situ (DCIS) with endocrine therapy remains controversial. A meta-analysis was conducted to evaluate the role of endocrine therapy for DCIS with breast conserving surgery (BCS) and radiotherapy (RT). A total of 7 articles with randomized controlled trials were included. Five articles compared the effects of BCS and RT followed by tamoxifen (TAM) or not (BCS + RT + TAM vs BCS + RT) and 2 compared the effects of TAM and anastrozole (ANA). TAM obviously reduced the rates of recurrence of ipsilateral breast cancer (IBCR), recurrence of contralateral breast cancer (CBCR), recurrence of ipsilateral invasive breast cancer (IBCR-INV) and recurrence of contralateral DCIS (CBCR-DCIS), and increased the rate of event-free survival (EFS)...

Patient-derived xenograft (PDX) models are increasingly being used in oncology drug development because they offer greater predictive value than traditional cell line models. Using novel tools to critique model validity and reliability we performed a systematic review to identify all original publications describing the derivation of PDX models of colon, prostate, breast and lung cancer. Validity was defined as the ability to recapitulate the disease of interest. The study protocol was registered with the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADES)...

Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer with poor clinical outcomes and lack of approved targeted therapy. Dysregulated microRNAs (miRNAs) have been considered a promising biomarker, which plays an important role in the tumorigenesis of human cancer. Due to the increase in miRNA profiling datasets of TNBC, a proper analysis is required for studying. Therefore, this study used meta-analysis to amalgamate ten miRNA profiling studies of TNBC. By the robust rank aggregation method, metasignatures of six miRNAs (4 upregulated: hsa-miR-135b-5p, hsa-miR-18a-5p, hsa-miR-9-5p and hsa-miR-522-3p; 2 downregulated: hsa-miR-190b and hsa-miR-449a) were obtained...
