About This PDQ Summary
About PDQPhysician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.Purpose of This SummaryThis PDQ cancer information summary has current
General Information About Cervical Cancer
Cervical cancer is a disease in which malignant (cancer) cells form in the tissues of the cervix. The cervix is the lower,narrow end of the uterus (the hollow,pear-shaped organ where a fetus grows). The cervix leads from the uterus to the vagina (birth canal). Cervical cancer usually develops slowly over time. Before cancer appears in the cervix,the cells of the cervix go through changes ...

Placental-Site Gestational Trophoblastic Tumor Treatment
Given the rarity of this tumor, reports of therapeutic results are confined to relatively small case series with accrual extending for very long time periods. Therefore, few reliable comparisons among surgical approaches or chemotherapeutic regimens can be made. Nevertheless, there are distinctions in underlying biology between placental-site gestational trophoblastic tumors (PSTTs) and the other gestational trophoblastic tumors—particularly resistance to chemotherapy—that justify specific treatment strategies, such as the following: Tumors confined to the uterus (Féderation Internationale de Gynécologie et d'Obstétrique [FIGO] Stage I).Hysterectomy is the treatment of choice.[1,2] In a relatively large, retrospective, population-based, consecutive, case series of 62 women with PSTT, 33 had disease confined to the uterus and were treated with hysterectomy (n = 17) or with hysterectomy plus chemotherapy (n = 16). Overall survival at 10 years was virtually identical between the
Stage Information for Gestational Trophoblastic Disease
Hydatidiform Mole (HM)HM (molar pregnancy) is disease limited to the uterine cavity. Gestational Trophoblastic NeoplasiaDefinitions: FIGOThe Féderation Internationale de Gynécologie et d'Obstétrique (FIGO) and the American Joint Committee on Cancer (AJCC) have designated staging to define gestational trophoblastic neoplasia; the FIGO system is most commonly used.[1,2] Some tumor registrars encourage the recording of staging in both systems.FIGO staging system (and modified World Health Organization [WHO] prognostic scoring system)The FIGO staging system is as follows:Table 1.

Cellular Classification of Uterine Sarcoma
The most common histologic types of uterine sarcomas include:Carcinosarcomas (mixed mesodermal sarcomas [40%–50%]).Leiomyosarcomas (30%).Endometrial stromal sarcomas (15%).The uterine neoplasm classification of the International Society of Gynecologic Pathologists and the World Health Organization uses the term carcinosarcomas for all primary uterine neoplasms containing malignant elements of both epithelial and stromal light microscopic appearances, regardless of whether malignant heterologous elements are present.References: Silverberg SG, Major FJ, Blessing JA, et al.: Carcinosarcoma (malignant mixed mesodermal tumor) of the uterus.

Stage IV Endometrial Cancer
Standard treatment options:Treatment of patients with stage IV endometrial cancer is dictated by the site of metastatic disease and symptoms related to disease sites. For bulky pelvic disease, radiation therapy consisting of a combination of intracavitary and external-beam radiation therapy is used. When distant metastases, especially pulmonary metastases, are present, hormonal therapy is indicated and useful. Observational studies support maximal cytoreductive surgery for patients with stage IV disease, although these conclusions need to be interpreted with care because of the small number of cases and likely selection bias.When possible, patients with stage IV endometrial cancer are treated with surgery, followed by chemotherapy, or radiation therapy, or both. For many years, radiation therapy was the standard adjuvant treatment for patients with endometrial cancer. However, several randomized trials have confirmed improved survival when adjuvant chemotherapy is used instead of
Stages of Gestational Trophoblastic Tumors and Neoplasia
After gestational trophoblastic neoplasia has been diagnosed, tests are done to find out if cancer has spread from where it started to other parts of the body. The process used to find out the extent or spread of cancer is called staging, The information gathered from the staging process helps determine the stage of disease. For GTN, stage is one of the factors used to plan treatment.The following tests and procedures may be done to help find out the stage of the disease: Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body onto film, making pictures of areas inside the body.CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography,
