BACKGROUND Since PI3K/AKT/mTOR pathway activation diminishes the effects of hormone therapy, combining aromatase inhibitors (anatrozole) with mTOR inhibitors (everolimus) was investigated. PATIENTS AND METHODS We evaluated anastrozole and everolimus in 55 patients with metastatic estrogen (ER) and/or progesterone receptor (PR)-positive breast and(More)
INTRODUCTION PRONOUNCE compared the efficacy and safety of pemetrexed+carboplatin followed by pemetrexed (Pem+Cb) with paclitaxel+carboplatin+bevacizumab followed by bevacizumab (Pac+Cb+Bev) in patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). METHODS Patients ≥18 years of age with stage IV nonsquamous NSCLC (American Joint Committee(More)
PURPOSE FBXW7 is a tumor suppressor gene responsible for the degradation of several proto-oncogenes. Preclinical data suggest that FBXW7 mutations sensitize cells to mTOR inhibitors. Clinicopathologic characteristics of cancer patients with FBXW7 mutations and their responses to mTOR inhibitors remain unknown. METHODS Using multiplex gene panels we(More)
The identification of new therapeutic uses for existing agents has been proposed as a means to mitigate the escalating cost of drug development. A common approach to such repurposing involves screening libraries of agents for activities against cell lines. In silico methods using knowledge from the biomedical literature have been proposed to constrain the(More)
PURPOSE This study aimed to assess MET amplification among different cancers, association with clinical factors and genetic aberrations and targeted therapy response modifications. EXPERIMENTAL DESIGN From May 2010 to November 2012, samples from patients with advanced tumors referred to the MD Anderson Phase I Clinic were analyzed for MET gene(More)
Recognition of molecular diversity in disease is required for the development of targeted therapies. We have developed a screening method based on phage display to select peptides recognized by the repertoire of circulating tumor-associated antibodies. Here we isolated peptides recognized by antibodies purified from the serum of prostate cancer patients. We(More)
BACKGROUND Bevacizumab and temsirolimus are active agents in advanced solid tumors. Temsirolimus inhibits mTOR in the PI3 kinase/AKT/mTOR pathway as well as CYP2A, which may be a resistance mechanism for cetuximab. In addition, temsirolimus attenuates upregulation of HIF-1α levels, which may be a resistance mechanism for bevacizumab. PATIENTS AND METHODS(More)
The purpose of this study was to evaluate the feasibility, efficacy, safety, and pharmacokinetics of trastuzumab plus cisplatin and gemcitabine in patients with Her2-overexpressing stages IIIB or IV non-small cell lung cancer (NSCLC) and to study the relationship between results from the two methods for determining levels of Her2 overexpression.

BACKGROUND Cholangiocarcinoma (CCA) is clinically heterogeneous; intra and extrahepatic CCA have diverse clinical presentations. Next generation sequencing (NGS) technology may identify the genetic differences between these entities and identify molecular subgroups for targeted therapeutics. METHODS We describe successful NGS-based testing of 75 CCA(More)
Despite a wealth of preclinical studies, it is unclear whether PIK3CA or phosphatase and tensin homolog (PTEN) gene aberrations are actionable in the clinical setting. Of 1,656 patients with advanced, refractory cancers tested for PIK3CA or PTEN abnormalities, PIK3CA mutations were found in 9% (146/1,589), and PTEN loss and/or mutation was found in 13%(More)
