BACKGROUND: Eribulin is a nontaxane microtubule inhibitor with activity in patients with metastatic breast cancer (MBC). We conducted a phase I dose-finding study of eribulin and capecitabine in patients with MBC pretreated with anthracycline and taxane. METHODS: Women with MBC aged ≤70 years were enrolled. A 3 + 3 dose escalation design was used: level 0 dosing, eribulin (1.4 mg/m(2) intravenously on days 1 and 8) plus capecitabine [825 mg/m(2) orally twice daily (BID)]; 2-weeks-on, 1-week-off in a 21-day cycle...

BACKGROUND: The degree of pathological response to neoadjuvant chemotherapy (NAC) was correlated with the prognosis in breast cancer. There are few studies published on inter-observer variability in the assessment of pathological responses among pathologists. METHODS: We collected 64 surgically resected specimens from patients who had received NAC. Three pathologists assessed the pathological responses and classified them into 7 grades according to grading system of the Japanese Breast Cancer Society...

BACKGROUND: The aim of this study was to investigate the prognostic significance of tumor location of lower inner zone (LIZ) on the survival of patients with early-stage breast cancer. METHODS: We retrospectively identified 961 breast cancer patients from Jan 2000 to Apr 2016 from hospital database. We evaluated overall survival (OS) and disease-free survival (DFS) in patients with tumors in and outside LIZ. Subgroup analyses were performed according to clinicopathological characteristics and treatment strategies...

INTRODUCTION: Heterologous breast reconstruction after mastectomy sometimes requires the management of the contralateral breast to achieve symmetric long lasting aesthetic results. Some techniques could be used for the symmetrization of contralateral breast with or without implants as breast augmentation, reduction mammoplasty, mastopexy, with T inverted, J, vertical, periareolar, semi-circular, or axillary scars. The aim of this study is to present the use of crescent mastopexy technique with implants in contralateral adjustment following monolateral breast reconstruction compared with a control group in which patients underwent other contralateral procedures...

BACKGROUND: In patients with hormone receptor-positive postmenopausal of early stage breast cancer, adjuvant endocrine monotherapies include letrozole, anastrozole, exemestane, toremifene and tamoxifen. But the optimum regimen remains controversial. METHODS: PubMed, Cochrane Database and ClinicalTrials.gov were systematically reviewed of abstract for randomized-controlled trials (RCTs) to assess the efficacy of tamoxifen, letrozole, exemestane, anastrozle and toremifene for postmenopausal patients with hormone-receptor positive (HR+), who have not received prior therapy for early stage breast cancer...

Circular RNAs (circRNAs) are a class of long, non-coding RNAs molecules that shape a covalently closed continuous loop which have no 5'-3' polarity and contain no polyA tail. CircRNAs also possess relatively jarless framework and are highly tissue-specific expressed in the eukaryotic transcriptome. Emerging evidences have discovered that thousands of endogenous circRNAs are present in mammalian cells and they mediate gene expression at the transcriptional or post-transcriptional level by binding to microRNAs or other molecules and then inhibit their function...

In 2014, the Early Breast Cancer Trialists' Collaborative Group (EBCTCG) reported that post-mastectomy radiation therapy (PMRT) for breast cancer patients with 1-3 cancer-positive lymph nodes is associated with a survival benefit. However, it is not known whether this applies to Japanese patients in daily clinical practice, because this conclusion was based on the results of older, western trials. Therefore, we studied the differences between PMRT results in western breast cancer patients and current practice in Japanese patients...

My arguments regarding postmastectomy radiotherapy (PMRT) for this case are based on the following 4 reasons: (1) high rate of local recurrence in the no PMRT group in the Early Breast Cancer Trialists' Collaborative Group meta-analysis on which the present guideline is based, (2) stage migration by sentinel node biopsy, (3) possible adverse events of radiotherapy, and (4) problems on extrapolation of data from western countries.

BACKGROUND: Recently, the use of taxane-based regimens before anthracycline-based regimens has been shown to achieve high pathological complete response (pCR) rates in patients with breast cancer. Nanoparticle albumin-bound paclitaxel (nab-PTX) has been reported as highly effective and less toxic compared with Cremophor-based Taxol. This phase II clinical trial evaluated the safety and efficacy of preoperative neoadjuvant chemotherapy (NAC) with nab-PTX followed by an epirubicin plus cyclophosphamide (EC)-based regimen for operable breast cancer...

BACKGROUND: Atypical femoral fracture (AFF) occurs with minor trauma in patients receiving antiresorptive drugs such as bisphosphonate and denosumab. We hypothesized that patients with bone metastasis who receive higher doses of antiresorptive drugs tend to experience AFF more frequently. This study aimed to investigate the prevalence rate of AFF in patients receiving antiresorptive drugs for bone metastasis of breast cancer. METHODS: Based on the database from our hospital, patients with breast cancer between March and September 2014 were investigated...

BACKGROUND: Whether a durometer was suitable for objectively measuring reconstructed breast hardness was evaluated. METHODS: Subjects were 81 women who underwent expander-implant reconstructions following breast cancer ablation. Capsular contracture was evaluated with Baker grading. Capsular thickness was measured with T1-weighted MRI at the upper areola area. The durometer was placed on the upper areola. Multiple logistic regression analysis was performed to compare variables...

BACKGROUND: Epidermal growth factor receptor (EGFR) is often overexpressed in triple-negative breast cancer (TNBC). However, clinical studies have shown that therapies against EGFR are not effective in patients with TNBC. Recently, it has been reported that arginine 198/200 in EGFR extracellular domain is methylated by PRMT1 and that the methylation confers resistance to EGFR monoclonal antibody cetuximab in colorectal cancer cells. To explore a potential mechanism underlying intrinsic resistance to anti-EGFR therapy in TNBC, we investigated the role of PRMT1 in EGFR methylation and signaling in MDA-MB-468 (468) TNBC cells...

Previous studies on the association between hormone replacement therapy (HRT) and breast cancer survival have yielded mixed results. We aimed to perform a meta-analysis to assess the association with all available studies. Relevant studies were identified by searching PubMed and EMBASE to April 2017. We calculated the summary hazard ratios (HRs) and 95% confidence intervals (CIs) using random-effects models. The dose-response relationship was assessed by random-effects meta-analysis and dose-response meta-regression models...

We describe a rare case of secondary breast carcinoma after chronic myeloid leukemia (CML) in a 56-year-old woman. The patient was treated with hydroxyurea and imatinib for CML and achieved complete remission (she has since been taking imatinib as the maintenance therapy). Four years later, the patient noticed a firm and painless lump in the left breast, which was diagnosed as ductal carcinoma in situ based on a percutaneous biopsy of the mass. Simple resection and sentinel lymph node biopsy of the left breast were then performed...

BACKGROUND: In breast reconstruction using a tissue expander (TE), sufficient coverage of the TE with the pectoralis major (PM) muscle, particularly with a musculofascial flap, is highly important for avoiding postoperative complications. In patients in whom the PM is thin, intraoperative trauma often occurs, leading to troublesome repair. The present study aimed to investigate the usefulness of preoperative measurement of PM thickness in planning of breast reconstruction using a TE. METHODS: In this case-control study, we identified 68 patients (70 breasts) with mammary carcinoma treated with simple mastectomy and TE insertion from April 2014 to December 2016...
