Ablation: treatment of tumors using different forms of targeted energy such as heat, cold, or forms of microwaves
Active: viable with possibility of success
Active Surveillance: Also called "watch and wait," is a disease management approach where patients are closely monitored through imaging, blood tests, and physical exams.
Arterial: involving arteries
Ascites: fluid accumulating in the abdomen
Baseline: first scan results against which all subsequent scans will be compared
Clear surgical margins: the tumor is removed with a layer of normal tissue all around the tumor surface
Comorbidities: the simultaneous presence of two or more diseases or medical conditions in a patient
Contraindication: reason not to receive a particular treatment or procedure
Cytokine: any of a number of substances, such as interferon, interleukin, and growth factors, which are secreted by certain cells of the immune system and have an effect on other cells
Epidemiology: the study and analysis of the distribution, patterns, and determinants of health and disease conditions in defined populations
Extrahepatic: anywhere in the body outside the liver
Hepatic: in the liver
Indolent: naturally stable cases to very slow-growing
Isolated limb perfusion: a treatment technique by which chemotherapy is only delivered in the affected region of the limb
Lesion: location of a tumor
Locoregional treatments: treatment not reaching every part of the body, but only the single treated site
Median survival: a statistic that refers to how long the majority of people survive with a disease in general or after a certain treatment
Multimodality: using different forms of therapy during a phase of treatment
Palliative care: a set of treatments providing relief from pain and other symptoms associated with cancer

Prognosis: explanation and forecast of how a person's EHE will progress and develop
Prospective clinical trials: studies in which included people are followed over time and data about them is collected as their characteristics or circumstances change
Pulmonary: in the lung
Radioembolization: radioactive beads deliver a small amount of radiation to the tumor and block blood supply at the same time
Radiosensitive: potentially responsive to radiation
Resected: removed by surgery
Reticulonodular opacities: a pattern resembling a net with small nodules
Retrospective series: studies including EHE cases looking backward at their clinical history
Sarcoma reference centers, sarcoma networks: centers with a recognized expertise in the treatment of sarcomas
Sarcoma: cancer originating in connective tissues, including cartilage, fat, muscle, blood vessels, fibrous tissue, bone
Shared decision-making: a collaborative process in which a patient and their healthcare provider work together to make decisions about care, combining the provider's clinical expertise with the patient's own values, preferences, circumstances, and goals.
Thoracic: in the chest cavity
Transarterial chemoembolization (TACE): delivering chemotherapy combined with blocking the blood supply to the tumors
Translocation: swapping of genetic material between two genes
Vascular: composed of neoplastic cells resembling blood vessels
Vascular graft: replacement of the removed segment of the vessel
Venous: involving veins
