Impact of BMI on HER2+ metastatic breast cancer patients treated with pertuzumab and/or trastuzumab emtansine. Real-world evidence

2020

Body mass index (BMI) is a main indicator of obesity and its association with breast cancer is well established. However, little is known in the metastatic setting, especially in HER2-positive patients. We assessed the influence of BMI on clinical outcomes of patients treated with pertuzumab and/or trastuzumab emtansine (T-DM1) for HER2+ metastatic breast cancer (mBC). BMI was addressed as a categorical variable, being classified on the basis of the following ranges, that is, 18.5-24.9, 25-29.9, and 30.0-34.9, namely, normal weight, overweight, and Class I obesity. The outcomes chosen were progression-free survival to first-line chemotherapy (PFS1) and overall survival (OS). Overall (N = 70…

Neoadjuvant Management of Early Breast Cancer: A Clinical and Investigational Position Statement

2019

AbstractBackgroundNeoadjuvant treatment is increasingly one of the preferred therapeutic options for early breast cancer and may have some unique outcomes, such as identifying predictive and prognostic factors of response or increasing the knowledge of individual tumor biology.DesignA panel of experts from different specialties reviewed published clinical studies on the neoadjuvant management of breast cancer. Recommendations were made that emphasized the clinical multidisciplinary management and the investigational leverage in early breast cancer.ResultsNeoadjuvant therapy has equivalent efficacy to adjuvant therapy, and it has some additional benefits that include increasing breast conser…

Efficacy and safety of Everolimus and Exemestane in hormone-receptor positive (HR+) human-epidermal-growth-factor negative (HER2−) advanced breast ca…

2017

Abstract Background The BOLERO-2 trial reported efficacy and safety of Everolimus (EVE) and Exemestane (EXE) combination in HR+ advanced breast cancer (ABC) patients. The BALLET trial further evaluated the safety of EVE-EXE in HR+ ABC patients, without reporting efficacy data. Aim of the EVA real-life study was to collect data of efficacy and safety of EVE-EXE combination in the clinical setting, as well as exploring efficacy according to EVE Dose-Intensity (DI) and to previous treatment with Fulvestrant. Patients and methods This study aimed to describe the outcome of ABC pts treated with EVE-EXE combination in terms of median duration of EVE treatment and ORR in a real-life setting. Resul…

Suppressive role exerted by microRNA-29b-1-5p in triple negative breast cancer through SPIN1 regulation

2017

MiR-29 family dysregulation occurs in various cancers including breast cancers. We investigated miR-29b-1 functional role in human triple negative breast cancer (TNBC) the most aggressive breast cancer subtype. We found that miR-29b-1-5p was downregulated in human TNBC tissues and cell lines. To assess whether miR- 29b-1-5p correlated with TNBC regenerative potential, we evaluated cancer stem cell enrichment in our TNBC cell lines, and found that only MDA-MB-231 and BT-20 produced primary, secondary and tertiary mammospheres, which were progressively enriched in OCT4, NANOG and SOX2 stemness genes. MiR-29b-1-5p expression inversely correlated with mammosphere stemness potential, and miR-29b…

Geriatric assessment and biomarkers in patients with metastatic breast cancer receiving first-line mono-chemotherapy: Results from the randomized pha…

2017

Abstract Objectives To determine predictive/prognostic factors for patients with metastatic breast cancer (MBC) receiving first-line monochemotherapy using biomarker analysis and geriatric assessment (GA). Materials and Methods Karnofsky Performance Status (KPS) and GA as clinical parameters, and prognostic inflammatory and nutritional index (PINI), and Glasgow prognostic score (GPS) as biomarkers were analyzed for association with clinical outcome within the randomized phase III PEg-LIposomal Doxorubicin vs. CApecitabin iN MBC (PELICAN) trial of first-line pegylated liposomal doxorubicin (PLD) or capecitabine. Results Of 210 patients, 38% were > 65 years old. GA (n = 152) classified 74% as…

Liquid Biopsy in Breast Cancer

2017

Breast cancer (BC) to date remains the most common cancer in women. Nowadays, BC is often diagnosed at local disease stage, and, after surgery, based on individual’s risk of relapse, the patients undergo adjuvant systemic treatment to decrease the risk of recurrence. Current BC classification and assessment remain strongly based on clinicopathological criteria, including patient age, tumor size, lymph node invasion, histological type, and grade. According to standard practice, the choice of treatment strategy includes assays for estrogen (ER) and progesterone (PgR) receptor expression levels, overexpression of human epidermal growth factor receptor 2 (Her-2), or amplification status of the …

Current treatment options for HER2-positive breast cancer patients with brain metastases

2020

Abstract Brain metastases (BMs) are frequently associated with HER2+ breast cancer (BC). Their management is based on a multi-modal strategy including both local treatment and systemic therapy. Despite therapeutic advance, BMs still have an adverse impact on survival and quality of life and the development of effective systemic therapy to prevent and treat BMs from HER2 + BC represents an unmet clinical need. Trastuzumab-based therapy has long been the mainstay of systemic therapy and over the last two decades other HER2-targeted agents including lapatinib, pertuzumab and trastuzumab emtansine, have been introduced in the clinical practice. More recently, novel agents such as neratinib, tuc…

Treatment of HER2 positive advanced breast cancer with T-DM1: A review of the literature

2014

Abstract Background Trastuzumab emtansine (T-DM1), a new agent developed for the treatment of HER2-positive breast cancer, is an antibody-drug conjugate with a complex compound obtained by the conjugation of trastuzumab, a stable thioether linker, and the potent cytotoxic drug maytansine-derivate(DM1), which inhibits cell division and induces cell death. Field of study PubMed database, ESMO, ASCO, San Antonio Breast Cancer Symposium Meeting abstracts and clinicaltrials.gov were searched using the terms “Anti-HER2 treatment breast cancer and trastuzumab emtansine (T-DM1) “; papers considered relevant for the aim of this review were selected. Findings/results The phase I trials have determine…
