Optimal cardiac dose constraints in breast cancer (BC) patients undergoing postoperative intensity-modulated radiation therapy (IMRT) are unclear, although as low as possible is recommended. This trial proposes serial cardiac dose constraint to optimize cardiac safety. Postoperative BC patients eligible for anthracycline/taxanes-based chemotherapy or HER2-targeted therapy were randomized to cardiac safety arm with prespecified mean heart dose (MHD) (≤6 Gy), V30 (≤20%), and V10 (≤50%) constraints, or to a control arm with in-house protocol (mainly MHD ≤8 Gy).

Introduction: Short course regimen has become the major trend in the field of adjuvant radiotherapy for patients with breast cancer. Hypofractionated radiotherapy (HF-RT) regimen of 40-42.5 Gy in 15-16 fractions has been established as a preferred option for whole breast irradiation.

Purpose: To determine the relationship between time to radiotherapy (TTR) and survival outcomes in breast cancer (BC) patients treated with neoadjuvant treatments (NATs).

Methods: Continuous non-metastatic BC patients receiving NAT and adjuvant radiotherapy (RT) from 2009 to 2016 were retrospectively reviewed. A multivariable Cox model with restricted cubic splines (RCSs) was used to determine the panoramic relationship between TTR and survival outcomes.

Growing evidence suggests that the bidirectional interactions between cancer cells and their surrounding environment, namely the tumor microenvironment (TME), contribute to cancer progression, metastasis, and resistance to treatment. Intense investigation of the Hippo pathway, which controls multiple central cellular functions in tumorigenesis, was focused on cancer cells. However, the role of the Hippo pathway in modulating tumor-stromal interactions in triple-negative breast cancer remains largely unknown.

Purpose: The aim of this study was to evaluate the impact of time to radiotherapy (TTR) after completion of chemotherapy (CT), and TTR after surgery, in breast cancer (BC) patients.

Patients And Methods: Continuous breast cancer patients treated with surgery and CT followed by radiotherapy (RT) from 2009 through 2015 were retrospectively reviewed. Patients were categorized into four groups with respect to TTR after CT, i.

This research aimed to construct a novel model for predicting overall survival (OS) and surgical benefit in triple-negative breast cancer (TNBC) patients with distant metastasis. We collected data from the Surveillance, Epidemiology, and End Results (SEER) database for TNBC patients with distant metastasis between 2010 and 2016. Patients were excluded if the data regarding metastatic status, follow-up time, or clinicopathological information were incomplete.

Objectives: Breast cancer has been the second most prevalent and fatal malignancy due to its frequent metastasis to other organs. We aim to study the effects of a key miRNA-mRNA signaling in breast cancer.

Results: CNN1 was identified as the key gene in breast cancer by the bioinformatics analysis, and the downregulation of CNN1 in breast cancer tissues and cell lines was observed.

Inflammatory breast cancer (IBC) is a fatal form of breast cancer. IBC patients present with unfavorable prognosis mainly attributable to high risk of distant metastasis. Thus, in this cohort study, we aimed to explore metastatic profiles of different molecular subtypes of IBC and elucidate the clinical and prognostic characteristics among different metastatic sites.

HER2-positive breast cancer (BC) achieving pathological complete remission (pCR) after neoadjuvant therapy (NAT) had a superior disease outcome. Dysmetabolism and stimulation of insulin-like growth factor 1 (IGF-1)-axis would increase BC risk, but we are lacking data for their association with pCR in HER2-positive+ BC. We aim to evaluate the pCR predictive value of above factors in HER2-positive BC patients receiving NAT.

This study evaluated the role of post-mastectomy radiotherapy (PMRT) in 111 patients with 1-3 positive nodes, aged 65 years or above between 2007 and 2013. In total, 64 received PMRT. The PMRT group had more aggressive tumor.

Background: The role of regional nodal irradiation (RNI) in patients with cN1 breast cancer following neoadjuvant treatment (NAT) is still controversial. The Neo-Bioscore staging system has shown promising prospect in assessing individual prognosis after NAT, and we sought to evaluate the role of Neo-Bioscore in guiding RNI following NAT.

Methods: Medical records of 163 women with cN1 and ypN0-1 disease treated with NAT between 2009 and 2014 were retrospectively reviewed and a Neo-Bioscore was assigned to each patient.

BACKGROUND Weight gain is a common side effect observed in breast cancer (BC) patients undergoing adjuvant chemotherapy, although the characteristics and mechanism are not been fully understood. This study aimed to investigate percent body fat (%BF) change, and identify the associated risk factors among Chinese women receiving chemotherapy for BC. MATERIAL AND METHODS A prospective longitudinal study was conducted on a cohort of 140 Chinese female patients with BC between June 2016 and October 2017.

Breast cancer (BC), obesity, and metabolic syndrome (MetS) shared a common mechanism of dysregulated metabolism and inflammatory response in disease initiation. Neutrophil-to-lymphocyte ratio (NLR) is associated with adverse survival of BC patients. The aim of this study is to identify risk effect between NLR and BC in Chinese population with or without obesity and MetS.

The study aims to identify clinical and pathological factors predictive of disease-free survival (DFS) and overall survival (OS) in locally advanced breast cancer (LABC) patients who do not have a pathologic complete response (no-pCR) of primary tumor after neoadjuvant chemotherapy (NC) with vinorelbine/epirubicin (VE) intravenous combination regimen. Retrospectively reviewed data of LABC patients in our Hospital. 97 patients who had no-pCR after NC were identified and enrolled in the study.

The aim of the present study was to investigate whether breast cancer patients with changes from positive to negative in the hormone receptor following neoadjuvant chemotherapy (NAC) could benefit from adjuvant endocrine therapy (ET). Between December 2000 and November 2010, 97 eligible patients with a positive-to-negative switch of the hormone receptor status following NAC were identified. All the patients were categorized into two groups on the basis of the administration of ET: 57 ET-administered and 40 ET-naïve patients.

Triple negative breast cancer (TNBC) is associated with high pathological complete remission (pCR) rate in neoadjuvant treatment (NAT). TNBC patients who achieve pCR have superior outcome than those without pCR. A meta-analysis was done to evaluate whether integrating novel approaches into NAT can improve the pCR rate in TNBC.
