Sugars, primarily glucose and fructose, are the main energy source of cells. Because of their hydrophilic nature, cells use a number of transporter proteins to introduce sugars through their plasma membrane. Cancer cells are well known to display an enhanced sugar uptake and consumption. In fact, sugar transporters are deregulated in cancer cells so they(More)
INTRODUCTION The skeleton is generally the primary, and sometimes the only, site of metastasis in patients with advanced solid tumors. Bone metastases are the most frequent cause of cancer-related pain and the origin of severe morbidity in patients. Among the treatment options available for the prevention of skeletal-related events (SREs) associated with(More)
Genes of the Wnt and Frizzled class, expressed in HNSCC tissue and cell lines, have an established role in cell morphogenesis and differentiation, and also they have oncogenic properties. We studied Wnt and Fz genes as potential tumor-associated markers in HNSCC by qPCR. Expression levels of Wnt and Fz genes in 22 unique frozen samples from HNSCC were(More)
BACKGROUND The efficacy of ceritinib in patients with untreated anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) is not known. We assessed the efficacy and safety of ceritinib versus platinum-based chemotherapy in these patients. METHODS This randomised, open-label, phase 3 study in untreated patients with stage IIIB/IV(More)
Molecular signatures associated with malignant phenotype would be useful for detection of micrometastatic carcinoma cells. The small breast epithelial mucin (SBEM) gene is predicted to code for a low molecular weight glycoprotein. To evaluate its potential role as a marker for bone marrow (BM) micrometastasis in breast cancer (BC) patients, we have studied(More)
All mammalian cells contain one or more members of the facilitative glucose transporter (GLUT) gene family. Glucose transporter membrane proteins (GLUT) regulate the movement of glucose between the extracellular and intracellular compartments, maintaining a constant supply of glucose available for metabolism. Tumor cells are highly energy-dependent,(More)
BACKGROUND Mutations in signalling pathways essential for embryonic development often lead to tumourigenesis, as is also true for Notch. The aim of this study was to assess the relationship between Notch1 to -4 and their ligands with anatomopathological features of the patients with renal cell carcinoma (RCC). MATERIALS AND METHODS This study investigated(More)
BACKGROUND Detection of tumor cells in the blood, or minimal deposits in distant organs as bone marrow, could be important to identify cancer patients at high risk of relapse or disease progression. Quantitative polymerase chain reaction (PCR) amplification of tissue or tumor selective mRNA is the most powerful tool for the detection of this circulating or(More)
BACKGROUND Afatinib has demonstrated clinical benefit in patients with non-small-cell lung cancer progressing after treatment with erlotinib/gefitinib. This phase III trial prospectively assessed whether continued irreversible ErbB-family blockade with afatinib plus paclitaxel has superior outcomes versus switching to chemotherapy alone in patients(More)
We report the case of a patient with subacute cerebellar degeneration presenting as paraneoplastic syndrome, preceding the final diagnosis of breast cancer. The tumor had high HER2 overexpression, so a weekly regimen of paclitaxel/trastuzumab was started after surgery of the primary breast tumor. Negativity of specific antineuronal antibodies and clinical(More)
