Several new systemic therapy options have become available for patients with metastatic breast cancer, which led to improvements in survival. In addition patient and clinical factors, the treatment selection primarily depends on tumor biology (hormone-receptor status HER2-status). The NCCN Guidelines specific workup of recurrent/stage IV cancer are discussed this article.
This randomized phase III trial compared the efficacy and safety of capecitabine with or without bevacizumab, a monoclonal antibody to vascular endothelial growth factor, in patients metastatic breast cancer previously treated an anthracycline taxane.Patients were randomly assigned receive (2,500 mg/m2/d) twice daily on day 1 through 14 every 3 weeks, alone combination bevacizumab (15 mg/kg) 1. The primary end point was progression-free survival (PFS), as determined by independent review...
To correlate the variable clinical features of oestrogen-receptor-positive breast cancer with somatic alterations, we studied pretreatment tumour biopsies accrued from patients in two studies neoadjuvant aromatase inhibitor therapy by massively parallel sequencing and analysis. Eighteen significantly mutated genes were identified, including five (RUNX1, CBFB, MYH9, MLL3 SF3B1) previously linked to haematopoietic disorders. Mutant MAP3K1 was associated luminal A status, low-grade histology...
Purpose Breast cancer arising in young women is correlated with inferior survival and higher incidence of negative clinicopathologic features. The biology driving this aggressive disease has yet to be defined. Patients Methods Clinically annotated, microarray data from 784 early-stage breast cancers were identified, prospectively defined, age-specific cohorts (young: ≤ 45 years, n = 200; older: ≥ 65 211) compared by prognosis, variables, mRNA expression values, single-gene analysis, gene set...
No single standard treatment exists for patients with small, node-negative, human epidermal growth factor receptor type 2 (HER2)-positive breast cancers, because most of these have been ineligible the pivotal trials adjuvant trastuzumab.We performed an uncontrolled, single-group, multicenter, investigator-initiated study paclitaxel and trastuzumab in 406 tumors measuring up to 3 cm greatest dimension. Patients received weekly 12 weeks, followed by 9 months monotherapy. The primary end point...
During cancer progression, malignant cells undergo epithelial-mesenchymal transitions (EMT) and mesenchymal-epithelial (MET) as part of a broad invasion metastasis program. We previously observed MET events among lung metastases in preclinical model prostate adenocarcinoma that suggested relationship between epithelial plasticity metastatic spread. thus sought to translate these findings into clinical evidence by examining the existence EMT circulating tumor (CTC) from patients with...
This study (EGF10004) assessed the safety/tolerability, pharmacokinetics, and clinical activity of daily oral dosing with lapatinib (GW572016) in patients ErbB1-expressing and/or ErbB2-overexpressing advanced-stage refractory solid tumors.Heavily pretreated metastatic cancers were randomly assigned to one five dose cohorts administered once daily. Pharmacokinetic samples obtained on days 1 20. Clinical response was every 8 weeks.Sixty-seven tumors treated lapatinib. The most frequently...
All cancers develop as a result of mutations in certain genes, such those involved the regulation cell growth and/or DNA repair, 1,2 but not all these are inherited from parent.For example, sporadic can occur somatic/ tumor cells only, and de novo for first time germ (i.e., egg or sperm) fertilized itself during early embryogen-
PURPOSE: Weight gain is a common problem among breast cancer patients who receive adjuvant chemotherapy (CT). We undertook study to determine the causes of this energy imbalance. PATIENTS AND METHODS: Factors related balance were assessed at baseline (within 3 weeks diagnosis) and throughout 1 year postdiagnosis 53 premenopausal women with operable carcinoma. Thirty-six received CT 17 only localized treatment (LT). Measures included body composition (dual x-ray absorptiometry), resting...
Preoperative aromatase inhibitor (AI) treatment promotes breast-conserving surgery (BCS) for estrogen receptor (ER)-positive breast cancer. To study this option, responses to three AIs were compared in a randomized phase II neoadjuvant trial designed select agents III investigations.Three hundred seventy-seven postmenopausal women with clinical stage ER-positive (Allred score 6-8) cancer randomly assigned receive exemestane, letrozole, or anastrozole. The primary end point was response....
Epidermal growth factor receptor (EGFR) is a targetable frequently overexpressed in basal-like breast cancer, which comprises most triple-negative cancers (TNBCs), the only subtype without established targeted therapy.In this randomized phase II trial, patients with metastatic TNBC received anti-EGFR antibody cetuximab (400 mg/m(2) load then 250 per week intravenously [IV]) alone, carboplatin (area under curve of 2, once IV) added after progression or as concomitant therapy from beginning....
