The IS1311 polymerase chain reaction-restriction endonuclease analysis was used to detect genetic differences among 38 Mycobacterium avium subsp. paratuberculosis (Map) isolates from cattle, sheep, goats and bison from distinct regions of Spain, India and the United States of America (USA). In Spain, all eight bovine isolates, three out of six caprine(More)
INTRODUCTION Pancreatic neuroendocrine neoplasms (PNENs) are uncommon neoplasms with a wide spectrum of clinical behavior. The objective of this study was to assess in a large cohort of patients the relative impact of prognostic factors on survival. METHODS From June 2001 through October 2010, 1,271 patients were prospectively registered online(More)
PURPOSE Doxorubicin and trabectedin are considered active drugs in soft tissue sarcoma (STS). The combination of both drugs was hypothesized to be advantageous and safe on the basis of preclinical evidence and a previous phase I trial, respectively. The aim of this study was to compare the clinical outcome of trabectedin plus doxorubicin with doxorubicin as(More)
Angiogenesis, resulting from an imbalance between angiogenic activator factors and inhibitors, is required for tumour growth and metastasis. The determination of the circulating concentration of all angiogenic factors (activators and inhibitors) is not feasible at present. We have evaluated diagnostic and prognostic values of the measurement of serum(More)
BACKGROUND Recurrent, metastatic, and locally advanced gastrointestinal stromal tumors (GISTs) can be treated successfully with imatinib mesylate. Surgery for residual disease has been suggested for nonrefractory metastatic GISTs to reduce the probability of resistant recurrent clones, although no randomized Phase III trial has been performed to answer the(More)
Somatostatin is an important regulator of endocrine and exocrine secretion, affecting the release of many hormones. The effects of somatostatin are mediated through its interaction with one of five somatostatin receptors. Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) express multiple somatostatin receptors, making them excellent potential(More)
BACKGROUND The management of advanced neuroendocrine tumors (NETs) has recently changed. We assessed the activity of pazopanib after failure of other systemic treatments in advanced NETs. METHODS This was a multicenter, open-label, phase II study evaluating pazopanib as a single agent in advanced NETs (PAZONET study). The clinical benefit rate (CBR) at 6(More)
PURPOSE To assess the progression-free survival (PFS) and antitumor response to standard-dose doxorubicin compared with sequential dose-dense doxorubicin and ifosfamide in first-line treatment of advanced soft tissue sarcoma. PATIENTS AND METHODS Patients with measurable advanced soft tissue sarcoma, Eastern Cooperative Oncology Group (ECOG) performance(More)
4113 Background: Sorafenib (S) and bevacizumab (B) as single agents have shown efficacy in NETs phase II trials. S+B combination has shown manageable toxicity in phase I trials in solid tumors. The aim of this study was to evaluate the efficacy and toxicity of the STI's combination in NETs. METHODS Phase II, controled clinical trial, carried out in 10(More)
Capecitabine is a drug that requires the consecutive action of three enzymes: carboxylesterase 2 (CES 2), cytidine deaminase (CDD), and thymidine phosphorylase (TP) for transformation into 5-fluorouracil (5FU). The metabolism of 5FU requires the activity of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) among other enzymes. The present(More)
