To evaluate the ability of fluorescence in situ hybridization (FISH) in detecting bladder urothelial carcinoma (BUC), FISH and cytology were compared for the evaluation of 308 consecutive urine samples from patients suspected of having BUC. »
S100 calcium binding protein A8 (S100A8) has been implicated as a prognostic indicator in several types of cancer. However, previous studies are limited in their ability to predict the clinical behavior of the cancer. Here, we sought to identify a molecular signature based on S100A8 expression and to assess its usefulness as a prognostic indicator of disease progression in non−muscle invasive bladder cancer (NMIBC). »
Because of intratumoral heterogeneity, diffusely infiltrating gliomas that lack significant contrast enhancement on magnetic resonance imaging are prone to tissue sampling error. Subsequent histologic undergrading may delay adjuvant treatments. 5−Aminolevulinic acid (5−ALA) leads to accumulation of fluorescent porphyrins in malignant glioma tissue, and is currently used for resection of malignant gliomas. »
Brain tumors such as medulloblastoma (MB) and glioblastoma multiforme (GBM) can derive from neural precursors. For instance, many MBs are thought to arise from the uncontrolled proliferation of cerebellar granule neuron precursors (GNP). GNPs normally proliferate in early postnatal stages in mice but then they become postmitotic and differentiate into granule neurons. »
Calcium signaling is important in many signaling processes in cancer cell proliferation and motility including in deadly glioblastomas of the brain that aggressively invade neighboring tissue. We hypothesized that disturbing Ca(2+) signaling pathways might decrease the invasive behavior of giloblastoma, extending survival. »
Melanoma differentiation associated gene−7(mda−7) encodes IL−24, a cytokine that can selectively trigger apoptosis in transformed cells. Recombinant mda−7 adenovirus (Ad.mda−7) effectively kills glioma cells, offering a novel gene therapy strategy to address deadly brain tumors. In this study, we defined the proximal mechanisms by which Ad−mda−7 kills glioma cells. »
The deprivation gap for breast cancer survival remains unexplained by stage at presentation, treatment, or co−morbidities. We hypothesised that p53 mutation might contribute to the impaired outcome observed in patients from deprived communities. »
Current clinical management of breast cancer relies on the availability of robust clinicopathological variables and few well−defined biological markers. Recent microarray−based expression profiling studies have emphasised the importance of the molecular portraits of breast cancer and the possibility of classifying breast cancer into biologically and molecularly distinct groups. »
Patients with the triple negative subtype of breast cancer have an overall poor outcome, with earlier relapses, distinct patterns of metastases, and lack of specific targets for treatment selection. Classification of these tumors has begun to be modified by inclusion of immunohistochemistry for various markers, and gene profiling. »
Multiple studies have suggested that resection of the primary tumor improves survival in patients with stage IV breast cancer, yet in the era of targeted therapy, the relation between surgery and tumor molecular subtype is unknown. The objective of the current study was to identify subsets of patients who may benefit from primary tumor treatment and assess the frequency of local disease progression »
