  • A dramatic increase in knowledge regarding the molecular biology of brain tumors has been established over the past few years, and this has lead to the development of novel therapeutic strategies for these patients. In this book a review of the options available for the clinical management of patients with these tumors are outlined. In addition advances in radiology both for pre-operative diagnostic purposes along with surgical planning are described.

  • There is a great difference between the superficial reading of a film and the proper interpretation of a clinical scintigraphic image by an imaging specialist. Fully utilizing the clinical image, the imaging specialist evaluates both the anatomical and the physiological structure of the human body. First the specialist must appreciate the patient’s clinical problem.Working from this clinical context, he then applies his understanding of the pathophysiological basis of disease and his knowledge of how such pathology may translate into various imaging patterns.

  • The interplay among reactive oxygen species (ROS) formation, elevated intracellular calcium concentration and mitochondrial demise is a recurring theme in research focusing on brain pathology, both for acute and chronic neurodegenerative states. However, causality, extent of contribution or the sequence of these events prior to cell death is not yet firmly established.

  • Combined methods have led to further refinements with, for example, high visuospatial resolution afforded by MRI combined with metabolic information from the lesion site (measured with 18F-fluorodeoxyglucose positron emission tomography; FDG-PET) to indicate location and malignancy of gliomas, which in turn informs radiosurgical targeting. Kapsalaki et al. (Chapter 7) consider MRS spectroscopic profiles for differentiation among ring enhancing lesions including high grade gliomas, abscesses and post-radiation necrosis.

  • Few fi elds of medicine have witnessed such impressive progress as the diagnosis and treatment of liver tumors. Advances in imaging technology, the development of novel contrast agents, and the introduction of optimized scanning protocols have greatly facilitated the non-invasive detection and characterization of focal liver lesions. Furthermore, image-guided techniques for percutaneous tumor ablation have become an accepted alternative treatment for patients with inoperable liver cancer.

  • Through the licensure of physicians in each country, we are permitted to treat female cancer patients. However, the treatment modalities contain medication of various anti-cancer drugs that can be associated with potentially fatal toxicity if they are not used correctly. In addition, surgery can also be associated with risks during our efforts to repair normal tissues or remove tumors. Such unfortunate events can be fatal.

  • Hepatocellular carcinoma (HCC) used to be regarded as a rare disease. The increasing numbers of chronic hepatitis C virus carriers in the United States and subsequent increased incidence of HCC seen in most large medical centers means that it is no longer an uncommon disease for most gastroenterologists or oncologists to encounter. During the times when liver resection or systemic chemotherapy were the only real therapeutic modalities available, the outcomes were generally dismal, especially because most patients presented with advanced-stage tumors.

  • Background: Pancreatic cancer is one of the most aggressive human tumors due to its high potential of local invasion and metastasis. The aim of this study was to characterize the membrane proteomes of pancreatic ductal adenocarcinoma (PDAC) cells of primary and metastatic origins, and to identify potential target proteins related to metastasis of pancreatic cancer.

  • are there breast cancer cells in your lymph nodes? Your doctor will examine your lymph nodes to see if they contain cancer. Having cancer cells in the lymph nodes under your arm is associated with an increased risk of the cancer spreading. Lymph nodes are filters along the lymph fluid channels. Lymph fluid leaves the breast and eventually goes back into the bloodstream. The lymph nodes try to catch and trap cancer cells before they reach other parts of the body. When lymph nodes are free, or clear, of cancer, the test results are called negative.

  • Formation of new blood vessels is required for the growth and metastasis of all solid tumors. New blood vessels are established in tumors mainly through angiogenesis. Brain tumors in particular are highly angiogenic. Therefore, interventions designed to prevent angiogenesis may be effective at controlling brain tumors.

  • Deficiency of the small mitochondrial protein frataxin causes Friedreich’s ataxia, a severe neurodegenerative pathology. Frataxin, which has been highly conserved throughout evolution, is thought to be involved in, among other processes, Fe–S cluster formation. Independent evidence shows that it binds iron directly, although with very distinct features and low affinity.

  • Vascular endothelial growth factor (VEGF) family members play impor-tant roles in embryonic development and angiogenesis during wound healing and in pathological conditions such as tumor formation. Parapox-viruses express a new member of the VEGF family which is a functional mitogen that specifically activates VEGF receptor (VEGFR)-2 but not VEGFR-1.

  • Cancer may constitute the most extensively studied disease entity of our time. Nevertheless, our comprehension of the cellular and molecular pathology of malignant transformation is incomplete. In view of the diverse clinical presentations of various malignancies, doubts may be raised as to whether it is appropriate to refer to cancer as one group of disease states. The notion of malignant tumors as a pathologic and pathophysiologic class of conditions begs the question for defining criteria that characterize all malignant growths, regardless of their tissue of origin....
