  1. Ovarian Low Malignant Potential Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Ovarian Low Malignant Potential Tumors

    Tumors of low malignant potential (i.e., borderline tumors) account for 15% of all epithelial ovarian cancers. Nearly 75% of these tumors are stage I at the time of diagnosis. These tumors must be recognized because their prognosis and treatment is clearly different from the frankly malignant invasive carcinomas.A review of 22 series (953 patients) with a mean follow-up of 7 years revealed a survival rate of 92% for patients with advanced-stage tumors, if patients with so-called invasive implants were excluded. The cause of death was determined to be benign complications of disease (e.g., small bowel obstruction), complications of therapy, and only rarely (0.7%), malignant transformation.[1] In one series, the 5-, 10-, 15-, and 20-year survival rates of patients with low malignant potential tumors (all stages), as demonstrated by clinical life table analysis, were 97%, 95%, 92%, and 89%, respectively.[2] In this series, mortality was stage dependent: 0.7%, 4.2%, and 26.8% of patients

    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

  4. Ovarian Germ Cell Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for Ovarian Germ Cell Tumors

    In the absence of obvious metastatic disease, accurate staging of germ cell tumors of the ovary requires laparotomy with careful examination of the following:Entire diaphragm.Both paracolic gutters.Pelvic nodes on the side of the ovarian tumor.The para-aortic lymph nodes.The omentum.The contralateral ovary should be carefully examined and biopsied if necessary. Ascitic fluid should be examined cytologically. If ascites is not present, it is important to obtain peritoneal washings before the tumor is manipulated. In patients with dysgerminoma, lymphangiography or computed tomography is indicated if the pelvic and para-aortic lymph nodes were not carefully examined at the time of surgery. Although not required for formal staging, it is desirable to obtain serum levels of alpha fetoprotein (AFP) and human chorionic gonadotropin (hCG) as soon as the diagnosis is established since persistence of these markers in the serum after surgery indicates unresected tumor.Definitions: FIGOThe

    Avoiding risk factors and increasing protective factors may help prevent cancer.Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking, eating a healthy diet, and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.The following risk factors may increase the risk of ovarian cancer:Family history of ovarian cancerA woman whose mother or sister had ovarian cancer has an increased risk of ovarian cancer. A woman with two or more relatives with ovarian cancer also has an increased risk of ovarian cancer. Inherited riskThe risk of ovarian cancer is increased in women who have inherited certain changes in the following genes:BRCA1 or BRCA2 genes.Genes that are linked to hereditary nonpolyposis colorectal cancer (HNPCC; Lynch syndrome).Hormone replacement

  9. Ovarian Germ Cell Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage IV Ovarian Germ Cell Tumors

    DysgerminomasStandard treatment options:Total abdominal hysterectomy and bilateral salpingo-oophorectomy with adjuvant chemotherapy.Unilateral salpingo-oophorectomy with adjuvant chemotherapy.For patients with stage IV dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy is recommended with removal of as much gross tumor in the abdomen and pelvis as can be done safely without resection of portions of the urinary tract or large segments of small or large bowel, although unilateral salpingo-oophorectomy should be considered in patients who wish to preserve fertility.[1,2] Chemotherapy with bleomycin/etoposide/cisplatin (BEP) can cure the majority of such patients. Stage IV dysgerminoma is not treated with radiation therapy, but rather with chemotherapy, preferably with three to four courses of cisplatin-containing combination chemotherapy such as BEP.[1] A second-look operation following treatment is rarely beneficial. (Refer to the PDQ summary on Sexuality and

  10. Ovarian Low Malignant Potential Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Advanced-Stage Ovarian Low Malignant Potential Tumors

    Patients with advanced disease should undergo a total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, node sampling, and aggressive cytoreductive surgery. Patients with stage III or IV disease with no gross residual tumor have had a 100% survival rate in some series regardless of the follow-up duration.[1,2] The 7-year survival rate of patients with gross residual disease was only 69% in a large series [3] and appears to be inversely proportional to the length of follow-up.[3]For patients with more advanced-stage disease and microscopic or gross residual disease, chemotherapy and/or radiation therapy are not indicated. Scant evidence exists that postoperative chemotherapy or radiation therapy alters the course of this disease in any beneficial way.[1,3,4,5,6] In a study of 364 patients without residual tumor, adjuvant therapy had no effect on disease-free or corrected survival when stratified for disease stage.[7] Patients without residual tumor who received no adjuvant
