Gestational Trophoblastic Neoplasm

Gestational trophoblastic neoplasm and choriocarcinoma are a group of strange diseases of pregnancy. It is suggested that you look at the home page link C. Understanding gestational trophoblastic disease for more information. Gestational trophoblastic neoplasm or choriocarcinoma occurs when the invasive system used for placental invasion or pregnancy implantation goes out of control. If a mother produces an extreme excess of hyperglycosylated hCG in the third trimester of pregnancy, it can drive the small amount of torn placental tissue remaining in the uterus after delivery of the baby and placenta, the extravillous cytotrophoblast, to grow like crazy and invade the whole body with cancer-like metastases in the lung and brain. Choriocarcinoma and gestational trophoblastic neoplasm can also be limited in some cases to the uterus and uterus and pelvis

Gestational trophoblastic neoplasm is not really a cancer, it is extravillous cytotrophoblast cells invading the body in a manner reminiscent of cancer but actually is just the normal placental invasion system gone out of control. This is driven by the autocrine that normally drives the placental growth and invasive system or hyperglycosylated hCG.

Physicians call the disease choriocarcinoma when pathology and histology has confirmed the identity of the cells. Until surgery is performed, and chemotherapy is the normal treatment, pathology and histology are not possible. As such some choriocarcinoma-like cases are always called gestational trophoblastic neoplasm, until surgery is performed and pathology and histology can identify them as choriocarcinoma cells. In this respect, choriocarcinoma and gestational trophoblastic neoplasm are basically one disease. These strange disease generally respond well and are successfully treated with chemotherapy treatment.
