Abstract:
Abstract The physical interaction between metastasis-initiating cells and the pre-existing capillary network (a process known as vascular co-option) is critical during the initial stages of multi-organ metastasis in cancer. As such, this process might provide an opportunity to prevent metastasis. As part of the process of vascular co-option, we observed that brain metastatic cells in the perivascular niche temporarily enter into a novel cell state characterized by a decreased proliferation before resuming their aggressive growth to colonize the organ.

Abstract PURPOSE Vessel co-option and vascular mimicry are important resistant factors with ant-angiogenic treatment for glioblastoma, but those precise evaluation is not clear. We had three types of glioblastoma surgically removed specimens treated with / without bevacizumab (Bev). Using these samples, pathogenesis of co-option and mimicry was morphometrically clarified. MATERIALS / METHODS Three types of glioblastoma specimens were analyzed; 1) Bev naive (N group, n 14), 2) Bev effective that was treated preoperative neoadjuvant Bev (E group, n 5), 3) Bev refractory that recurred with contin

Abstract:
Background: Vascular co-option is one of the main features of brain tumor progression. It is identified using histopathological analysis, but no antibody-specific markers were found, and no universally accepted histological features were defined. Methods: We employed double immunohistochemical stainings for CD31, P-gp, S100A10, and mitochondria on formalin-fixed, paraffin-embedded human samples of IDH-WT glioblastoma, IDH-mutant astrocytoma, and meningioma to study vascular co-option across different brain tumors and across normal, peritumoral, and intratumoral areas using the Aperio colocaliz

2059 Background: Understanding the pathobiology of brain metastases (BM) could guide the establishment of new targeted therapies. Methods: We collected 57 autopsy specimens of BM (primary tumor: 27 lung cancer, 6 breast cancer, 8 melanoma, 1 kidney cancer, 2 colorectal cancer, 13 other) and histologically evaluated the patterns of invasion into the surrounding brain parenchyma. Expression of the following integrins was evaluated using immunohistochemistry: with novel antibodies for αv subunit, αvβ3, αvβ5, αvβ6 and αvβ8 integrin. Results: We observed three main invasion patterns: well-demarcate

Abstract:
Angiogenesis is a crucial event in the physiological processes of embryogenesis and wound healing. During malignant transformation, dysregulation of angiogenesis leads to the formation of a vascular network of tumor-associated capillaries promoting survival and proliferation of the tumor cells. Starting with the hypothesis formulated by Judah Folkman that tumor growth is angiogenesis-dependent, this area of research has a solid scientific foundation and inhibition of angiogenesis is a major area of therapeutic development for the treatment of cancer. Over this period numerous authors published

Abstract:
Abstract Vessel co-option is the movement of cancer cells towards and along the pre-existing vasculature and is an alternative to angiogenesis to gain access to nutrients. Vessel co-option has been shown as a strategy employed by some glioblastoma (GBM) cells to invade further into the brain, leading to one of the greatest challenges in treating GBM. In GBM, vessel co-option may be an intrinsic feature or an acquired mechanism of resistance to anti-angiogenic treatment. Here, we describe the histological features and the dynamics visualized through intravital microscopy of vessel co-option in

Abstract:
Patients presenting for vascular surgery typically have significant comorbidities. Procedures can vary from minor to quite large with significant blood loss and fluid shifts, and can be elective or emergent. Perioperative morbidity and mortality in the context of co-existing cardiovascular disease, diabetes, dementia and other factors all provide great concern to the anesthesiologist in their approach towards the vascular patient. The anesthetic approach to such patients must therefore be taken with great forethought. Many times, these procedures can be localized to a particular extremity or well-defined set of dermatomes, and regional anesthesia has become one important option for the complicated vascular patient. In this chapter, the risks, benefits, and feasibility of various regional techniques are discussed in the context of patients presenting for carotid endarterectomy, vascular access placement, and major lower extremity vascular surgery.
