What does disseminated mean in cancer?
disseminated cancer in British English (dɪˈsɛmɪˌneɪtɪd ˈkænsə ) noun. medicine. a cancerous tumour that has spread from the site of original growth to a secondary site.
What are disseminated cancer cells?
In patients with cancer, disseminated cancer cells are often detectable in the peripheral blood as circulating tumour cells (CTCs) and in the bone marrow or lymph nodes as disseminated tumour cells (DTCs).
Is metastasized cancer fatal?
In most cases, metastatic cancer is not curable. However, treatment can slow growth and ease many of the associated symptoms. It’s possible to live for several years with some types of cancer, even after it has metastasized. Some types of metastatic cancer are potentially curable, including melanoma and colon cancer.
What is the pathway of cancer dissemination?
There are three primary ways tumors can spread to distant organs: Through the circulatory (blood) system (hematogenous) Through the lymphatic system. Through the body wall into the abdominal and chest cavities (transcoelomic).
What is advanced disseminated malignant disease?
Disseminated disease refers to a diffuse disease-process, generally either infectious or neoplastic. The term may sometimes also characterize connective tissue disease. A disseminated infection, for example, has extended beyond its origin or nidus and involved the bloodstream to “seed” other areas of the body.
Does anyone survive metastatic cancer?
Until recently, long-term survivors of advanced or metastatic cancer have primarily been women with metastatic breast cancer. But doctors are now seeing survivors with other types of cancer, including lung, gastrointestinal, kidney cancer, and melanoma.
What causes cancer to metastasize?
Metastases most commonly develop when cancer cells break away from the main tumor and enter the bloodstream or lymphatic system. These systems carry fluids around the body.
What do you mean disseminated?
Definition of disseminate transitive verb. 1 : to spread abroad as though sowing seed disseminate ideas. 2 : to disperse throughout.
What would be a good example of a disseminated infection?
Examples of Disseminated Infection Sexually transmitted infections (STIs) can readily disseminate from the primary site (such as the genitals, anus, or mouth) to other parts of the body if left untreated. Some of the most serious forms include disseminated syphilis and gonorrhea.
What does disseminated disease mean?
A disseminated infection is one in which a localized infection spreads (disseminates) from one area of the body to other organ systems. While there are systemic infections that can affect the entire body at once, doctors will reserve the term for those infections that are normally constrained to a specific site.
What is disease dissemination?
What does the disseminated mean?
What are the different types of disseminated cancer?
The following cancers are considered as disseminated cancer: acute lymphocytic leukemia (ALL), acute myelogenous leukemia (AML), and stage IV lymphoma. The following are not considered as disseminated cancer: chronic lymphocytic leukemia (CLL), chronic myelogenous leukemia (CML), stages I through III lymphomas or multiple myeloma.
What is the prognosis of disseminated cancer?
While early stage solid tumors are curable by surgical resection and/or adjuvant therapy, disseminated cancers typically have a poor prognosis and require alternative therapeutic approaches, including the targeting of cellular mechanisms supporting uncontrolled cellular proliferation and metastasis.
Do disseminated cancer cells require self-renewal capability to spawn metastases?
In order to spawn macroscopic metastases, disseminated cancer cells would seem to require self-renewal capability.
