All terms in NCIT

Label	Id	Description
Nerve Sheath Neoplasm	NCIT_C4972	[A benign or malignant neoplasm arising from the perineural cells in the sheaths surrounding the nerves. Representative examples include neurofibroma, schwannoma, and malignant peripheral nerve sheath tumor.]
Benign Nervous System Neoplasm	NCIT_C4789	[Abnormal growth of cells in the nervous system without evidence of malignant characteristics. Unlike other organ systems, tumors in the central nervous system can have benign histological characteristics but still have life threatening effects due to their location within the neuraxis (e.g., brainstem gliomas).]
Trilateral Retinoblastoma	NCIT_C7019	[Trilateral retinoblastoma refers to bilateral (or less often unilateral) retinoblastoma associated with an intracranial primitive neuroectodermal tumor in the pineal or suprasellar region. This syndrome is often associated with a increased familial incidence of retinoblastoma. (From Cancer 86(1): 135-141, 1999).]
Central Nervous System Immature Teratoma	NCIT_C7014	[A teratoma involving the central nervous system and characterized by the presence of an extensive component of immature, fetal-type tissues.]
Central Nervous System Teratoma	NCIT_C5441	[A mature or immature teratoma that affects the central nervous system.]
Immature Extragonadal Teratoma	NCIT_C8884	[An immature teratoma that develops as a primary tumor in an anatomic site other than the testis or ovary.]
Central Nervous System Teratoma with Malignant Transformation	NCIT_C7015	[A central nervous system teratoma characterized by the presence of a malignant component. The malignant component most often is sarcomatous (rhabdomyosarcoma or undifferentiated sarcoma) or carcinomatous (squamous cell carcinoma or adenocarcinoma).]
Malignant Extragonadal Non-Seminomatous Germ Cell Tumor	NCIT_C8885	[A malignant non-seminomatous germ cell tumor that develops as a primary tumor in an anatomic site other than the testis or ovary.]
Central Nervous System Mixed Germ Cell Tumor	NCIT_C7016	[A malignant germ cell tumor of the central nervous system characterized by the presence of at least two types of germ cell neoplasia.]
Mixed Germ Cell Tumor	NCIT_C4290	[A malignant germ cell tumor characterized by the presence of at least two different germ cell tumor components. The different germ cell tumor components include choriocarcinoma, embryonal carcinoma, yolk sac tumor, teratoma, and seminoma. It occurs in the ovary, testis, and extragonadal sites including central nervous system and mediastinum.]
Granular Cell Tumor of the Sellar Region	NCIT_C7017	[A generally benign intrasellar and/or suprasellar mass arising from the neurohypophysis or infundibulum. It is composed of nests of large cells with granular, eosinophilic cytoplasm due to abundant intracytoplasmic lysosomes. It generally has a slow progression and lacks invasive growth. (Adapted from WHO)]
Grade 5 Autoimmune Disorder, CTCAE	NCIT_C146227	[Death]
Autoimmune Disorder, CTCAE	NCIT_C143310	[A disorder characterized by loss of function or tissue destruction of an organ or multiple organs, arising from humoral or cellular immune responses of the individual to his own tissue constituents.]
Grade 5 Avascular Necrosis, CTCAE	NCIT_C146228	[Death]
Avascular Necrosis, CTCAE	NCIT_C143311	[A disorder characterized by necrotic changes in the bone tissue due to interruption of blood supply. Most often affecting the epiphysis of the long bones, the necrotic changes result in the collapse and the destruction of the bone structure.]
Grade 5 Bile Duct Stenosis, CTCAE	NCIT_C146229	[Death]
Bile Duct Stenosis, CTCAE	NCIT_C143314	[A disorder characterized by a narrowing of the lumen of the bile duct.]
High-LET Neutron Therapy	NCIT_C15440
Central Nervous System Embryonal Carcinoma	NCIT_C7010	[A malignant germ cell tumor of the central nervous system composed of large cells that proliferate in cohesive nests and sheets. In rare occasions, tumor cells may replicate the structure of the early embryo, forming "embryoid bodies" replete with germ discs and miniature amniotic cavities. Additional morphologic characteristics include enlarged nucleoli, abundant clear to somewhat violet-hued cytoplasm, a high mitotic rate and zones of coagulative necrosis. (Adapted from WHO)]
Central Nervous System Nongerminomatous Germ Cell Tumor	NCIT_C100093	[Germ cell tumors of the central nervous system other than germinoma. This category includes teratoma, choriocarcinoma, embryonal carcinoma, and yolk sac tumor.]
