Gestational Trophoblastic Tumors

Gestational Trophoblastic tumours or GTTs generally originate in the womb that is diverse from womb cancers. Womb cancers grow from the cells that constitute the womb, while a gestational trophoblastic tumor develops from tissues which form the womb and are components of the usual foetal development during the gestational or pregnancy phase.

Generally subsequent to fertilization of the egg by the sperm, novel cells start developing that lead to the formation of an embryo. With the continual growth of the embryo, the cells within it begin specialising with some of them forming the foetus and rest of them forming the placenta. The foremost cell layer which forms the placenta is known as the trophoblast.

Those women having GTT have anomalous cell growth and development of the tissues forming the womb during pregnancy leading to the formation of the tumor. GTTs are of varying forms namely molar pregnancy, PSTT or placental site trophoblastic tumour, choriocarcinoma, invasive mole, persistent trophoblastic disease, gestational trophoblastic neoplasia and disease.

The GTT is a tumor that could either be benign or malignant in nature. Though they generally originate in the womb, they have a tendency of behaving different from a womb cancer. The course of treatment in case of GTTs is additionally different from a womb cancer.

Development of GTTs

The initial cell layer that grows to form the placenta is known as the trophoblasts which produce small, tentacle-alike growths called villi. Such villi fasten themselves to the womb lining. During molar pregnancy, there is either no development or anomalous or improper normal growth of the foetus. The villi could exhibit swelling and start growing in cluster-formations resembling a cluster of cherries. In case one is having continual GTT (choriocarcinoma), then a number of trophoblastic cells start having abnormal growth and form tumors that might metastasize beyond the area of the womb.

Molar pregnancies are the prevalent form of GTT and are non-cancerous or benign in nature. Typically, molar pregnancies could turn malignant and could reach other areas of the body. Gestational trophoblastic tumors treatment of all its forms is possible irrespective of them being malignant or benign.

Risk Factors

Below mentioned are the risk factors, though the presence of one or more of them would not necessarily translate to one contracting this disease.

• Age
  Those women past the age of forty years and those lesser than twenty years old are at greater risk, though age is lesser of a risk factor in case of partial moles. As GTTs are the consequence of an anomalous pregnancy, hence all the females in their fertile years are at some form of risk of developing the disease.
• Past history of molar pregnancy
  In case a woman has earlier developed molar pregnancy or a hydatidiform mole then nearly one among sixty likelihood of her developing it again is there. Yet ninety-eight percent of the following pregnancies would be normal ones.
• No gestational past
  Women that have no past history of pregnancy or gestation could be at a somewhat greater risk.
• Blood Group
  Females belonging to blood groups of either A or AB have been noted to have a somewhat greater likelihood of developing the disease as compared to those women belonging to the blood groups of B or O.
• Birth Control Pills
  Women on a course of oral contraceptive pills could be facing greater risk to some extent.
• Sexual Past
  Those women that have in the past had above ten sexual mates could be at a greater risk.
