INTRODUCTION: Most patients with HER2-positive breast cancer receive chemotherapy and trastuzumab. Data from adjuvant trials have shown that the combination of docetaxel, carboplatin and weekly trastuzumab (TCH) is well tolerated and as effective as anthracycline-containing regimes. Previous investigations on neoadjuvant treatment with taxanes, platinum salts and trastuzumab showed pathological complete remission (pCR) rates between 43.3 and 76%. To date, the longest published follow-up in this indication is 3 years...

BACKGROUND: Decision-making for or against neoadjuvant or adjuvant chemotherapy in postmenopausal patients with hormone receptor-positive breast cancer does not follow any clear guidelines, and some patients may unnecessarily undergo chemotherapy and be exposed to the associated toxicity. The aim of this study was to identify the patient population for whom this issue may bear relevance. METHODS: Patients being treated with letrozole in the prospective multicenter noninterventional EvAluate-TM study were recruited...

BACKGROUND: There is no consensus on the need for adjuvant chemotherapy for patients with pathological residual invasive breast cancer (non-pCR) after neoadjuvant chemotherapy (NAC). We evaluated the tolerability and safety of tegafur-uracil (UFT) as adjuvant chemotherapy for patients with human epidermal growth factor receptor 2-negative breast cancer that resulted in non-pCR after NAC. PATIENTS AND METHODS: We treated patients with 270 mg/m(2) UFT per day for 2 years after definitive surgery and radiotherapy, if necessary...

REVIEW
Alberto A Gabizon, Yogita Patil, Ninh M La-Beck
We herein review various pharmacological and clinical aspects of pegylated liposomal doxorubicin (PLD), the first nanomedicine to be approved for cancer therapy, and discuss the gap between its potent antitumor activity in preclinical studies and its comparatively modest achievements in clinical studies and limited use in clinical practice. PLD is a complex formulation of doxorubicin based on pharmaceutical nanotechnology with unique pharmacokinetic and pharmacodynamic properties. Its long circulation time with stable retention of the payload and its accumulation in tumors with high vascular permeability both result in important advantages over conventional chemotherapy...

Breast cancer patients with Luminal A disease generally have a good prognosis, but among this patient group are patients with good prognosis that are currently overtreated with adjuvant chemotherapy, and also patients that have a bad prognosis and should be given more aggressive treatment. There is no available method for subclassification of this patient group. Here we present a DNA methylation signature (SAM40) that segregates Luminal A patients based on prognosis, and identify one good prognosis group and one bad prognosis group...

INTRODUCTION: Oncoplastic breast surgery is used to extend the role of breast-conserving surgery (BCS) to women with an unfavourable tumour to breast volume ratio. However, large-breasted women with a relatively small breast cancer may be offered bilateral reduction mammoplasty (BRM) despite being suitable for standard BCS as the more complex surgery may have advantages in terms of patient satisfaction and reduced adverse effects of radiotherapy. PATIENT AND METHODS: This retrospective study evaluated surgical and patient-reported outcome measures (PROMs) in large-breasted women with early (<3 cm) breast cancer, who have undergone unilateral standard BCS or BRM...

BACKGROUND: Multidisciplinary team (MDT) meetings are used to optimise expert decision-making about treatment options, but such expertise is not digitally transferable between centres. To help standardise medical decision-making, we developed a machine learning model designed to predict MDT decisions about adjuvant breast cancer treatments. METHODS: We analysed MDT decisions regarding adjuvant systemic therapy for 1065 breast cancer cases over eight years. Machine learning classifiers with and without bootstrap aggregation were correlated with MDT decisions (recommended, not recommended, or discussable) regarding adjuvant cytotoxic, endocrine and biologic/targeted therapies, then tested for predictability using stratified ten-fold cross-validations...

: Neuroendocrine carcinoma of the breast is an extremely rare tumor. A standard treatment has yet to be established because only a few cases have been reported in literature. The authors report five cases observed from January 2007 to December 2014 and a review of literature. Four patients underwent quadrantectomy and in two cases axillary nodal dissection and only one to mastectomy with axillary nodal dissection. Tumor size was from T1 to T2 with N0 to N1, according TNM classification...

PURPOSE: Hormone receptor-positive (HR+) breast cancer is clinically and biologically heterogeneous and subgroups with different prognostic and treatment sensitivities need to be identified. EXPERIMENTAL DESIGN: Research-based PAM50 subtyping and expression of additional genes was performed on 63 patients with HR+/HER2- disease randomized to neoadjuvant multi-agent chemotherapy versus endocrine therapy in a phase II trial. The biology associated with treatment response was used to derive a PAM50-based Chemo-Endocrine Score (CES)...

Approximately 70% of patients have breast cancers that are oestrogen receptor alpha positive (ER+) and are therefore candidates for endocrine treatment. Many of these patients relapse in the years during or following completion of adjuvant endocrine therapy. Thus, many ER+ cancers have primary resistance or develop resistance to endocrine therapy during treatment. Recent improvements in our understanding of how tumours evolve during treatment with endocrine agents have identified both changes in gene expression and mutational profiles, in the primary cancer as well as in circulating tumour cells...

BACKGROUND: Muscle dysfunction and sarcopenia have been associated with poor performance status, an increased mortality risk, and greater side effects in oncologic patients. However, little is known about how performance is affected by cancer therapy. We investigated muscle strength in breast cancer patients in different adjuvant treatment settings and also compared it with data from healthy individuals. METHODS: Breast cancer patients (N = 255) from two randomized controlled exercise trials, staged 0-III and aged 54...

BACKGROUND: Male breast cancer is a rare event, accounting for approximately 1% of all breast carcinomas. Although men with breast cancer had poorer survival when compared with women, data on prognosis principally derive from retrospective studies and from extrapolation of female breast cancer series. We reported the case of a very long survival patient. CASE PRESENTATION: A caucasian 42-year-old man underwent radical mastectomy with axillary dissection for breast cancer in 1993...

Adjuvant chemo- and/or radiotherapy is applied in majority of patients treated because of early stage breast cancer even though only a small fraction of them is at high risk of metastasis or recurrence. Hence, knowledge of biomarkers associated with risk of disease progression might help planning of an optimal therapy, and to protect large group of patients from toxicity of unnecessary treatment. Here we aimed to characterize serum proteome of patients diagnosed with early stage breast cancer who either showed no evidence of disease five years after the end of therapy or suffered from metastasis, relapse or second cancer during corresponding follow-up...

Increased mammographic density (MD) has been shown beyond doubt to be a marker for increased breast cancer risk, though the underpinning pathobiology is yet to be fully elucidated. Estrogenic activity exerts a strong influence over MD, which consequently has been observed to change predictably in response to tamoxifen anti-estrogen therapy, although results for other selective estrogen receptor modulators and aromatase inhibitors are less consistent. In both primary and secondary prevention settings, tamoxifen-associated MD changes correlate with successful modulation of risk or outcome, particularly among pre-menopausal women; an observation that supports the potential use of MD change as a surrogate marker where short-term MD changes reflect longer-term anti-estrogen efficacy...

BACKGROUND: HER2-overexpressing breast cancer (BC) is common among young patients and poses a public health burden. Adjuvant anti-HER2/neu therapy with trastuzumab reduces the risk of recurrence and improves survival. METHODS: A web-based survey was sent to 386 physicians of the "TEACH" trial in 2011 to determine access to HER2/neu testing and treatment patterns for HER2-overexpressing BC. RESULTS: There were 151 responders (39%) from 28 countries...

Purpose The primary toxicity of trastuzumab therapy for human epidermal growth factor receptor 2-overexpressing (HER2-positive) breast cancer is dose-independent cardiac dysfunction. Angiotensin-converting enzyme inhibitors and β-blockers are recommended first-line agents for heart failure. We hypothesized that angiotensin-converting enzyme inhibitors and β-blockers could prevent trastuzumab-related cardiotoxicity. Patients and Methods In this double-blinded, placebo-controlled trial, patients with HER2-positive early breast cancer were randomly assigned to receive treatment with perindopril, bisoprolol, or placebo (1:1:1) for the duration of trastuzumab adjuvant therapy...

Purpose: Decisions as to whether to provide adjuvant treatment in older breast cancer patients remains challenging. Side effects of chemotherapy have to be weighed against life expectancy, comorbidities, functional status, and frailty. To aid decision-making, we retrospectively analyzed 110 women with breast cancer treated with a curative intention from 2006 to 2012. Survival data with clinical and pathological parameters were evaluated to address the role of adjuvant chemotherapy in this study population. Method: A total of 110 elderly (>70 years) patients that received mastectomy at two hospitals in Taiwan were observed retrospectively for a medium of 51 months...
