INTRODUCTION Translocation of the anaplastic lymphoma kinase (ALK) gene is involved in the tumorigenesis of a subset of non-small cell lung carcinomas (NSCLCs) and identifies patients sensitive to ALK inhibitors. ALK copy number changes and amplification, which plays an oncogenic role in tumors such as neuroblastoma, are poorly characterized in NSCLC. We(More)
Metalloproteinase 7 (MMP-7) plays an important role in tumor growth, invasion and dissemination, and is secreted to the media. Because of the close implication of MMP-7 in cancer biology, we sought to define the prognostic significance of serum levels of MMP-7 in metastatic colorectal cancer (CRC) and explore its possible impact in the daily clinical(More)
The JAK2V617F allele burden has been identified as a risk factor for vascular events and myelofibrotic transformation in polycythemia vera (PV) and essential thrombocythemia (ET). However, all previous studies have evaluated a single time point JAK2V617F measurement. Therefore, the frequency and the clinical significance of changes in the JAK2V617F mutant(More)
PURPOSE Oxaliplatin-5-fluorouracil combinations have increased responses in first-line therapy up to 40% in advanced colorectal cancer. Unfortunately, those patients who will respond are unknown and initially sensitive patients become rapidly resistant to current therapies. FAS (CD95) and FAS ligand (FASL; CD95L) have been implicated in chemosensitivity(More)
Insulin-like growth factor-I (IGF-I) is thought to have antiapoptotic and mitogenic properties in colorectal cancer, whereas IGF-binding protein-3 (IGFBP-3) seems to exert a pro-apoptotic effect. Additionally, matrix metalloproteinase-7 (MMP-7), an enzyme with in vitro ability to degrade IGFBP-3, has been shown to be a prognostic factor in advanced(More)
JAK2V617F-negative essential thrombocythemia (ET) is a heterogeneous disease including clonal cases and others without evidence of clonality. However, it is unknown if the detection of myeloid clonality in JAK2V617F-negative ET patients confers a different clinical outcome than those in whom clonal hematopoiesis cannot be demonstrated. The objective of the(More)
Matrix metalloproteinase 7 (MMP-7) is involved in invasion, metastasis, growth, and angiogenesis. The aim of this study is to assess the prognostic role of serum MMP-7 in curatively resected colorectal cancer (CRC). Patients undergoing resection for CRC (n = 175) were recruited from July 2003 to December 2004. MMP-7 was determined using a quantitative solid(More)
BACKGROUND To assess if surgical manipulation increases peripheral blood cancer cells dissemination in early stage (I and II) breast cancer patients. PATIENTS AND METHODS We analyzed 64 patients using RT-PCR for cytokeratin-19 as a marker for peripheral blood breast cancer cell dissemination. Peripheral blood was obtained at 4 different time-points (24(More)
