Angiogenesis
Angiogenesis is an active process, regulating new vessel growth, and is crucial for the survival and growth of tumours next to other complex factors in the tumour microenvironment. We present possible molecular imaging approaches for tumour vascularisation and vitality, focusing on radiopharmaceuticals (tracers). Molecular imaging in general has become an integrated part of cancer therapy, by bringing relevant insights on tumour angiogenic status.

Angiogenesis and de novo Arteriogenesis
Arteriogenesis supply oxygen and nutrients in tumor microenvironment (TME), which may play an important role in tumor growth and metastasis. Current anti-angiogenetic targeted treatments have not shown substantial clinical benefits and they are poorly tolerated, and even lead to more malignant relapse. The heterogeneity of tumor-associated endothelial cells (TAECs) and tumor vasculature may be important and should be appreciated in therapeutic targeting the TME. In this regard, the de novo arteriogenesis within the TME may be associated with tumor progression, stemness of cancer stem-like cells (CSCs) and therapeutic resistance and relapse. Targeting tumor arteriogenesis may thus be a potential novel therapeutic target. Specifically, targeting the FoxO1-CD36-Notch pathway could show the clinical potential by acting on arteriolar niche and CSCs at the same time in a variety of cancers including neuroendocrine cancers, breast cancers, lung cancers and malignant melanoma.

Angiogenesis in Adrenocortical Tumors
Angiogenesis plays an important role in several physiological and pathological processes. Pharmacological angiogenesis modulation has been robustly demonstrated to achieve clinical benefits in several cancers. Adrenocortical carcinomas (ACC) are rare tumors that often have a poor prognosis. In addition, therapeutic options for ACC are limited. Understanding the mechanisms that regulate adrenocortical angiogenesis along the embryonic development and in ACC could provide important clues on how these processes could be pharmacologically modulated for ACC treatment. In this report, we performed an integrative review on adrenal cortex angiogenesis regulation in physiological conditions and ACC. During embryonic development, adrenal angiogenesis is regulated by both VEGF and Ang-Tie signaling pathways. In ACC, early research efforts were focused on VEGF signaling and this pathway was identified as a good prognostic factor and thus a promising therapeutic target.

Angiogenesis in Cancer and Its Therapeutic Targeting
Vascular endothelial growth factors (VEGFs) are the key regulators of vasculogenesis in normal and oncological development. VEGF-A is the most studied angiogenic factor secreted by malignant tumor cells under hypoxic and inflammatory stress, which made VEGF-A a rational target for anticancer therapy. However, inhibition of VEGF-A by monoclonal antibody drugs led to the upregulation of VEGF-D. VEGF-D was primarily described as a lymphangiogenic factor; however, VEGF-D’s blood angiogenic potential comparable to VEGF-A has already been demonstrated in glioblastoma and colorectal carcinoma. These findings suggested a role for VEGF-D in facilitating malignant tumor growth by bypassing the anti-VEGF-A antiangiogenic therapy. Owing to its high mitogenic ability, higher affinity for VEGFR-2, and higher expression in cancer, VEGF-D might even be a stronger angiogenic driver and, hence, a better therapeutic target than VEGF-A.

Angiogenesis in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. The hypervascular nature of the majority of HCCs and the peculiar vascular derangement occurring during liver carcinogenesis underscore the importance of angiogenesis in the development and progression of these tumors. Indeed, several angiogenic molecular pathways have been identified as deregulated in HCC. The hypervascular nature and the peculiar vascularization of HCC, as well as deregulated angiogenic pathways, represent major therapeutic targets.

Angiogenesis in NAFLD
Non-alcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease, exposing to the risk of liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC).

Angiogenic Factors in Endometrial Cancer
Endometrial cancer (EC) is the most frequent gynecological malignancy in developed countries and requires a relatively invasive diagnostic evaluation and operative therapy as the primary therapeutic approach. Angiogenesis is one of the main processes needed for cancer growth and spread. The production of angiogenic factors (AFs) appears early in the process of carcinogenesis. The detection of AFs in plasma and tissue and a better understanding of the angiogenic properties of EC may contribute not only to earlier but also more specific diagnosis and consequently tailored and individual therapeutic approaches. AFs and their receptors also have high potential as binding sites for targeted cancer therapy.

Angiogenic Growth Factors in Immunosuppression and Immune Escape
Angiogenesis is seen as the process that mediates new blood vessel formation and capillaries, an essential process allowing for the exchange of nutrients throughout the body. Angiogenic growth factors (AFs) influence both innate and adaptive immune cell populations within the tumor microenvironment (TME) to create a more tolerogenic milieu. Myeloid regulatory cells such as myeloid-derived suppressor cells (MDSCs), tumor-associated macrophages (TAMs), type 2 natural killer T (NKT) cells, and regulatory T-cells (Tregs) are the primary cells types that contribute to immune escape and immunosuppression within the tumor microenvironment.

Angiogenic Switch
Regular physical activity in cyclic sports can influence the so-called “angiogenic switch”, which is considered as an imbalance between proangiogenic and anti-angiogenic molecules. Disruption of the synthesis of angiogenic molecules can be caused by local changes in tissues under the influence of excessive physical exertion and its consequences, such as chronic oxidative stress and associated hypoxia, metabolic acidosis, sports injuries, etc.

Angiography and Embolization Technique for Hepatocellular Carcinoma
Image-guided locoregional therapies play a crucial role in the management of patients with hepatocellular carcinoma (HCC). Transarterial therapies consist of a group of catheter-based treatments where embolic agents are delivered directly into the tumor via their supplying arteries. Some of the transarterial therapies available include bland embolization (TAE), transarterial chemoembolization (TACE), drug-eluting beads–transarterial chemoembolization (DEB–TACE), selective internal radioembolization therapy (SIRT), and hepatic artery infusion (HAI).
