Germ cell tumor (GCT) is a neoplasm derived from the primordial germ cells. [1] Germ-cell tumors can be cancerous or benign. Germ cells normally occur inside the gonads (ovary [2] and testis). GCTs that originate outside the gonads may be birth defects resulting from errors during development of the embryo.
The following is a list of cancer types.Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1]
Germ cell tumor is a rare cancer that can affect people at all ages. As of 2018, germ cell tumors account for 3% of all cancers in children and adolescents 0–19 years old. [22] Germ cell tumors are generally located in the gonads but can also appear in the abdomen, pelvis, mediastinum, or brain. Germ cells migrating to the gonads may not ...
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
Ovarian germ cell tumors (OGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad, which accounts for about 2.6% of all ovarian malignancies. [1] There are four main types of OGCTs, namely dysgerminomas , yolk sac tumor , teratoma , and choriocarcinoma .
As with other germ-cell tumors (GCTs) occurring outside the gonads, the most common location of intracranial germinoma is on or near the midline, often in the pineal or suprasellar areas; in 5-10% of patients with germinoma in either area, the tumor is in both areas. Like other GCTs, germinomas can occur in other parts of the brain.
Germ cell tumors often carry abnormality of chromosome 12, which if identified, directs treatment for metastatic germ cell tumors. [medical citation needed] No method is standard for all forms of CUP, but chemotherapy, radiation therapy, hormone therapy, and surgery may be used alone or in combination to treat patients who have CUP. Even when ...
A dysgerminoma is a type of germ cell tumor; [1] it usually is malignant and usually occurs in the ovary.. A tumor of the identical histology but not occurring in the ovary may be described by an alternate name: seminoma in the testis [2] or germinoma in the central nervous system or other parts of the body.
