  1. Evidence of Benefit

    Human PapillomavirusEpidemiologic studies to evaluate risk factors for the development of squamous intraepithelial lesions (SIL) and cervical malignancy demonstrate conclusively a sexual mode of transmission of a carcinogen.[1] It is now widely accepted that human papillomavirus (HPV) is the primary etiologic infectious agent.[2,3,4] Other sexually transmitted factors, including herpes simplex virus 2 and Chlamydia trachomatis, may play a cocausative role.[1] The finding of HPV viral DNA integrated in most cellular genomes of invasive cervical carcinomas supports epidemiologic data linking this agent to cervical cancer.[5] More than 80 distinct types of HPV have been identified, approximately 30 of which infect the human genital tract. HPV types 16 and 18 are most often associated with invasive disease. Characterization of carcinogenic risk associated with HPV types is an important step in the process of developing a combination HPV vaccine for the

  2. Epithelioid Trophoblastic Tumor Treatment

    These tumors are exceedingly rare. There is little information to guide therapy. However, they are similar in behavior and prognosis to placental-site trophoblastic tumors, so it is reasonable to manage them similarly. (Refer to the Placental-Site Gestational Trophoblastic Tumor Treatment section of this summary for more information.) Only a minority of these tumors are malignant in behavior, but they are not very responsive to systemic therapy. A variety of chemotherapy regimens have been used.[1]Current Clinical TrialsCheck for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with epithelioid trophoblastic tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.General information about clinical trials is also available from the NCI Web site.References: Palmer JE, Macdonald M, Wells M, et al.: Epithelioid trophoblastic tumor: a review of the literature.

  4. Stage IVA Cervical Cancer

    The size of the primary tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy.[1] After surgical staging, patients found to have small volume para-aortic nodal disease and controllable pelvic disease may be cured with pelvic and para-aortic radiation therapy. Five randomized, phase III trials have shown an overall survival advantage for cisplatin-based therapy given concurrently with radiation therapy,[2,3,4,5,6,7,8] while one trial examining this regimen demonstrated no benefit.[9] The patient populations in these studies included women with Féderation Internationale de Gynécologie et d'Obstétrique (FIGO) stages IB2 to IVA cervical cancer treated with primary radiation therapy and women with FIGO stages I to IIA disease who, at the time of primary surgery, were found to have poor prognostic factors, which include the following: Metastatic disease in pelvic lymph nodes.Parametrial disease.Positive surgical margins.Although the

  5. 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

  7. Evidence of Harm

    Annually in the United States, an estimated 65 million women undergo cervical cancer screening;[1] about 3.9 million (6%) will be referred for further evaluation.[2] About 11,000 cases of invasive cervical cancer were diagnosed in 2008. Thus, Papanicolaou (Pap) test screening results in a large number of colposcopies for benign conditions.The major potential harm of screening for cervical cancer lies in the screening detection of many cytologic abnormalities such as atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL), the majority of which would never progress to cervical cancer. Women with human papillomavirus (HPV)-positive ASCUS or LSIL on Pap testing are usually referred for colposcopy. Histological CIN 2+ is treated with cryotherapy or loop electrosurgical excision procedure. These procedures permanently alter the cervix and have consequences on fertility and pregnancy.[3] Younger women are more likely to acquire HPV

  8. Cervical Cancer Screening

    Tests are used to screen for different types of cancer.Some screening tests are used because they have been shown to be helpful both in finding cancers early and in decreasing the chance of dying from these cancers. Other tests are used because they have been shown to find cancer in some people; however, it has not been proven in clinical trials that use of these tests will decrease the risk of dying from cancer.Scientists study screening tests to find those with the fewest risks and most benefits. Cancer screening trials also are meant to show whether early detection (finding cancer before it causes symptoms) decreases a person's chance of dying from the disease. For some types of cancer, the chance of recovery is better if the disease is found and treated at an early stage.Clinical trials that study cancer screening methods are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site.Studies show that screening for
