Breast cancer may affect young women who have not yet completed childbearing. Assisted reproductive technology (ART) provides alternatives for fertility preservation such as oocyte, embryo or ovarian tissue cryopreservation. We reviewed the published literature on fertility-preserving management in breast cancer, aiming at finding evidence to answer the following questions: (1) What are the fertility sparing options available?; (2) How do these women respond to IVF? and (3) Can pregnancy influence breast cancer recurrence? There is a paucity of publications describing clinical experience and outcome data which limits accessibility to fertility preservation in this setting...

The ShcA adaptor protein transduces oncogenic signals downstream of receptor tyrosine kinases. We show here that breast tumors engage the ShcA pathway to increase their metabolism. ShcA signaling enhanced glucose catabolism through glycolysis and oxidative phosphorylation, rendering breast cancer cells critically dependent on glucose. ShcA signaling simultaneously increased the metabolic rate and flexibility of breast cancer cells by inducing the PGC-1α transcription factor, a central regulator of mitochondrial metabolism...

The presence of cancer stem cells (CSCs) and the induction of epithelial-to-mesenchymal transition (EMT) in tumors are associated with tumor aggressiveness, metastasis, drug resistance, and poor prognosis, necessitating the development of reagents for unambiguous detection of CSC- and EMT-associated proteins in tumor specimens. To this end, we generated novel antibodies to EMT- and CSC-associated proteins, including Goosecoid, Sox9, Slug, Snail, and CD133. Importantly, unlike several widely used antibodies to CD133, the anti-CD133 antibodies we generated recognize epitopes distal to known glycosylation sites, enabling analyses that are not confounded by differences in CD133 glycosylation...

Prediction of drug combinations that effectively target cancer cells is a critical challenge for cancer therapy, in particular for triple-negative breast cancer (TNBC), a highly aggressive breast cancer subtype with no effective targeted treatment. As signalling pathway networks critically control cancer cell behaviour, analysis of signalling network activity and crosstalk can help predict potent drug combinations and rational stratification of patients, thus bringing therapeutic and prognostic values. We have previously showed that the non-receptor tyrosine kinase PYK2 is a downstream effector of EGFR and c-Met and demonstrated their crosstalk signalling in basal-like TNBC...

PURPOSE: We hypothesized that an increase in BMI category during neoadjuvant chemotherapy (NAC) would be associated with pathological complete response (pCR) rate and worse survival outcomes in primary breast cancer patients. METHODS: We reviewed the records of 4029 patients with stage I-III breast cancer who had undergone NAC and definitive surgery at our institution between May 1, 1990 and April 30, 2013. BMI values at baseline and after NAC were recorded, and the corresponding BMI category was assessed with the WHO classification...

Targeted cancer therapy with natural compounds is more effective than nontargeted therapy. Nobiletin is a flavonoid derived from citrus peel that has anticancer activity. Cluster of differentiation 36 (CD36) is a member of the class B scavenger receptor family that is involved in importing fatty acids into cells. CD36 plays a role in tumor angiogenesis by binding to its ligand, thrombospondin-1 (TSP-1), and then interacting with transforming growth factor beta 1 (TGFβ1). CD36 is implicated in tumor metastasis through its roles in fatty acid metabolism...

BACKGROUND: Pregnancy-associated breast cancer (PABC) is rare and is generally defined as breast cancer diagnosed during pregnancy or within 1 year of delivery. The average ages of marriage and childbearing are increasing, and PABC is expected to also increase. This study is intended to increase understanding of the characteristics of PABC. METHODS: A database of 2,810 patients with breast cancer diagnosed when they were less than 40 years of age was reviewed. The clinicopathological factors and survival of PABC (40 patients) were compared to those of patients with young breast cancer (YBC, non-pregnant or over 12 months after delivery; 2,770 patients)...

STUDY QUESTION: What is the impact of cancer in females aged ≤39 years on subsequent chance of pregnancy? SUMMARY ANSWER: Cancer survivors achieved fewer pregnancies across all cancer types, and the chance of achieving a first pregnancy was also lower. WHAT IS KNOWN ALREADY: The diagnosis and treatment of cancer in young females may be associated with reduced fertility but the true pregnancy deficit in a population is unknown. STUDY DESIGN, SIZE, DURATION: We performed a retrospective cohort study relating first incident cancer diagnosed between 1981 and 2012 to subsequent pregnancy in all female patients in Scotland aged 39 years or less at cancer diagnosis (n = 23 201)...

BACKGROUNDS: This study aimed to compare the oncologic outcomes of nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM) followed by immediate reconstruction with those of conventional mastectomy (CM) in young patients aged under 35 years old with breast cancer. METHODS: We analyzed retrospectively 2889 patients who underwent mastectomy for breast cancer at Asan Medical Center from January 2003 to December 2008. We compared NSM/SSM followed by immediate reconstruction with CM in patients under 35 years old by analyzing clinicopathologic features, breast cancer specific survival rate (BCSS), distant metastasis free survival rate (DMFS), and local recurrence rate (LRR)...

A proliferation-inducing ligand (APRIL), which induces survival and migration signals and tumor growth, is commonly observed in breast cancer tissues but is not often expressed in breast cancer cells themselves. Here, we examined whether breast cancer cells induce APRIL secretion from neutrophils, which are frequently recruited into the breast tumor microenvironment. We found that breast cancer cells do stimulate neutrophils to secrete APRIL through their glycosaminoglycans. Breast cancer cells depleted of heparan sulfate or chondroitin sulfate glycosaminoglycans lose their ability to induce APRIL secretion from neutrophils, and heparan sulfate and chondroitin sulfate can induce secretion that is comparable to that of breast cancer cell-induced secretion...

The major hallmarks of tumor progression are angiogenesis, migration and metastasis. Among the components of Rhodiola rosea, salidroside (p‑hydroxyphenethyl-β‑d-glucoside) is one of the most potent, and is present in all Rhodiola species. Recent data have revealed the anticancer effects of salidroside; however, the mechanism underlying its ability to inhibit tumor angiogenesis remains unknown. The present study aimed to analyze how salidroside affects major factors involved in breast cancer, and to elucidate its ability to inhibit angiogenesis and invasion...

INTRODUCTION: Breast cancer in young women tends to be more aggressive, but timely treatment may not be always available, particularly to those without health insurance. We aim to examine whether the dependent coverage expansion under the Affordable Care Act (ACA-DCE) implemented in 2010 was associated with changes in time to treatment among women diagnosed with early stage breast cancer. METHODS: A total of 7,176 patients diagnosed with early stage breast cancer in 2007-2009 (pre-ACA) and 2011-2013 (post-ACA) were identified from the National Cancer Database...

Background: The breast cancer (BC) epidemic is a multifactorial disease attributed to the early twenty-first century: about two million of new cases and half a million deaths are registered annually worldwide. New trends are emerging now: on the one hand, with respect to the geographical BC prevalence and, on the other hand, with respect to the age distribution. Recent statistics demonstrate that young populations are getting more and more affected by BC in both Eastern and Western countries...
