Authoritative information and practical advice from the nation's cancer experts about gestational trophoblastic tumors - hydatidiform mole, choriocarcinoma, GTD, GTT, GTN, PSTT - includes official medical data on signs, symptoms, early detection, diagnostic testing, risk factors and prevention, treatment options, surgery, radiation, drugs, chemotherapy, staging, biology, prognosis, and survival, with a complete glossary of technical medical terms and current references.Starting with the basics, and advancing to detailed patient-oriented and physician-quality information, this comprehensive in-depth compilation gives empowered patients, families, caregivers, nurses, and physicians the knowledge they need to understand the diagnosis and treatment of GTD.Comprehensive data on clinical trials related to GTD/GTT is included - - with information on intervention, sponsor, gender, age group, trial phase, number of enrolled patients, funding source, study type, study design, NCT identification number and other IDs, first received date, start date, completion date, primary completion date, last updated date, last verified date, associated acronym, and outcome measures.Gestational trophoblastic tumor, a rare cancer in women, is a disease in which cancer (malignant) cells grow in the tissues that are formed following conception (the joining of sperm and egg). Gestational trophoblastic tumors start inside the uterus, the hollow, muscular, pear-shaped organ where a baby grows. This type of cancer occurs in women during the years when they are able to have children. There are two types of gestational trophoblastic tumors: hydatidiform mole and choriocarcinoma.If a patient has a hydatidiform mole (also called a molar pregnancy), the sperm and egg cells have joined without the development of a baby in the uterus. Instead, the tissue that is formed resembles grape-like cysts. Hydatidiform mole does not spread outside of the uterus to other parts of the body. If a patient has a choriocarcinoma, the tumor may have started from a hydatidiform mole or from tissue that remains in the uterus following an abortion or delivery of a baby. Choriocarcinoma can spread from the uterus to other parts of the body. A very rare type of gestational trophoblastic tumor starts in the uterus where the placenta was attached. This type of cancer is called placental-site trophoblastic disease. Gestational trophoblastic tumor is not always easy to find. In its early stages, it may look like a normal pregnancy. A doctor should be seen if there is vaginal bleeding (not menstrual bleeding) and if a woman is pregnant and the baby hasn't moved at the expected time.Extensive supplements, with chapters gathered from our Cancer Toolkit series and other reports, cover a broad range of cancer topics useful to cancer patients.
