All terms in NCIT

Label	Id	Description
Ethylene Oxide	NCIT_C29821	[Colorless, odorless, flammable, toxic gaseous cyclic ether with a sweet ether-like smell. Ethylene oxide is used especially in the synthesis of ethylene glycol and as a sterilizing agent for medical supplies and foods, as a fumigant and as an insecticide. Exposure to this substance is highly irritating to the eyes, skin and respiratory tract, induces nausea and vomiting and causes central nervous system depression. Ethylene oxide is mutagenic in humans and chronic exposure is associated with an increased risk of leukemia, stomach cancer, pancreatic cancer and non-Hodgkin lymphoma. (NCI05)]
Carcinogenic Epoxide	NCIT_C45408	[A ring-shaped organic compound that can potentially cause cancer in humans and consists of an oxygen atom bonded to two other atoms, usually of carbon, that are already bonded to each other. (NCI05)]
Ferric-Nitrilotriacetate	NCIT_C29822
Hydroquinone	NCIT_C29823	[Produced as an inhibitor, an antioxidant, and an intermediate in the synthesis of dyes, motor fuels, and oils; in photographic processing; and naturally in certain plant species, Hydroquinone is a phenol derivative with antioxidant properties that can cause toxicity in several organs, notably the kidney. Used as a topical treatment for skin hyperpigmentation and in various cosmetic products, it is metabolized mainly to glutathione conjugates and forms mutagenic DNA adducts in in-vitro systems. (NCI04)]
Isoprene	NCIT_C29824	[An unsaturated pentahydrocarbon, Isoprene is found in certain plants or obtained by distillation of caoutchouc or gutta-percha. In plants, it is elementary in the formation of isoprenoids, fat-soluble vitamins, carotenoids and related pigments. Isoprenes contribute to flavors and fragrances of essential oils and other plant-derived substances. (NCI04)]
Chlordane	NCIT_C29814	[Chlordane is a chlorinated hydrocarbon used as a non-systemic contact insecticide for lawns and crops. Actually a complex mixture of isomers, other chlorinated hydrocarbons, and by-products, chlordane is used in termite and ant control, and as a protective treatment for underground cables. Chlordane may be irritant and toxic by ingestion, inhalation, or skin absorption; toxic effects may be cumulative. When heated to decomposition, chlordane emits toxic fumes of carbon monoxide, hydrogen chloride, chlorine, and phosgene. Chlordane is very persistent in the environment, surviving in soils for more than 20 years. U.S. production of chlordane was stopped in 1976. (NCI04)]
Chloroform	NCIT_C29815	[A colorless, volatile, liquid derivative of trichloromethane with an ether-like odor. Formerly used as an inhaled anesthetic during surgery, the primary use of chloroform today is in industry, where it is used as a solvent and in the production of the refrigerant freon. Acute chloroform toxicity results in impaired liver function, cardiac arrhythmia, nausea and central nervous system dysfunction. As a byproduct of water chlorination, chloroform may be present in small amounts in chlorinated water. (NCI04)]
Crocidolite Asbestos	NCIT_C29816	[A naturally occurring, blue, fibrous amphibole asbestos mineral. Crocidolite is used extensively in industry for various purposes. Chronic inhalation of its dust may cause asbestosis and increases the risk of respiratory tract cancer, mesothelioma and other lung cancers. Crocidolite asbestos is a known human carcinogen. (NCI05)]
Asbestos	NCIT_C284	[One of a number of fibrous magnesium and calcium silicate minerals processed for thermal insulation and fireproofing. Asbestos is considered to be an environmental carcinogen; chronic inhalation of fine asbestos dust causes pulmonary asbestosis and may induce lung neoplasms. Chronic ingestion of asbestos may induce gastrointestinal neoplasms. (NCI04)]
Croton Oil	NCIT_C29817	[A yellow to brown colored, thick, foul smelling, very toxic oil obtained from the seeds of a tropical plant, Croton Tiglium. Croton oil was used as a drastic purgative agent, but is now mostly used as a standard irritant in pharmacological research. Exposure to this substance causes severe skin irritation and affects the small intestine leading to severe diarrhea. Croton oil is a possible human carcinogen. (NCI05)]
Cyclopenta[cd]pyrene	NCIT_C29818	[An aromatic hydrocarbon that consists of five fused rings and is formed during the incomplete combustion of organic matter. Cyclopenta[c,d]pyrene is primarily found in gasoline engine exhaust. This substance is used in laboratory research as a mutagen and carcinogen. Cyclopenta[c,d]pyrene is reasonably anticipated to be a human carcinogen. (NCI05)]
Ether	NCIT_C29819	[An organic compound in which two carbon atoms are linked through an oxygen atom (C-O-C). An ether may be a product of the condensation of alcohols. Ether also refers loosely to diethyl-ether, a colorless, volatile, highly inflammable liquid used in industry and biomedical research, and historically important as an anesthetic agent. In vivo, ether acts similarly to alcohol and chloroform, but its stimulant action on the heart is much more marked. Ether is a rapidly diffusible stimulant. (NCI04)]
Primary Cutaneous Marginal Zone Lymphoma of Mucosa-Associated Lymphoid Tissue	NCIT_C7230	[A low-grade, extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue that arises from the skin. It usually presents with multifocal papular or nodular lesions in the arms or trunk. It rarely disseminates to internal organs or progresses to high grade lymphoma.]
Grade 5 Peritoneal Infection, CTCAE	NCIT_C146483	[Death]
Peritoneal Infection, CTCAE	NCIT_C143753	[A disorder characterized by an infectious process involving the peritoneum.]
Small Intestinal Non-Hodgkin Lymphoma	NCIT_C7231	[A B-cell or T-cell non-Hodgkin lymphoma that arises from the small intestine. Representative examples of B-cell non-Hodgkin lymphoma include diffuse large B-cell lymphoma, MALT lymphoma, alpha heavy chain disease/immunoproliferative small intestinal disease, Burkitt lymphoma, follicular lymphoma, and mantle cell lymphoma. The T-cell non-Hodgkin lymphomas are the enteropathy-associated T-cell lymphoma and the monomorphic CD56 positive intestinal T-cell lymphoma.]
Small Intestinal Lymphoma	NCIT_C4007	[A non-Hodgkin or Hodgkin lymphoma that arises from the small intestine.]
Digestive System Non-Hodgkin Lymphoma	NCIT_C38161	[A non-Hodgkin lymphoma that arises from any part of the digestive system, with the bulk of the disease localized to that site.]
Grade 5 Peritoneal Necrosis, CTCAE	NCIT_C146484
Neoplastic Post-Transplant Lymphoproliferative Disorder	NCIT_C7232	[A lymphoproliferative disorder arising as a result of post-transplant immunosuppression therapy. It is characterized by the presence of tissue destruction and effacement of the architecture of the involved tissues. There is clonal rearrangement of the immunoglobulin or the T-cell receptor genes. It includes the following variants: polymorphic, monomorphic, and classical Hodgkin lymphoma type post-transplant lymphoproliferative disorders.]
