  1. Pheochromocytoma and Paraganglioma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Pheochromocytoma During Pregnancy

    Pheochromocytoma diagnosed during pregnancy is extremely rare (0.007% of all pregnancies).[1,2] However, this situation deserves mention because women with hereditary conditions that increase the risk of developing pheochromocytoma are often also of child-bearing age, and the outcome of undiagnosed pheochromocytoma during pregnancy can be catastrophic.DiagnosisPrenatal diagnosis clearly results in decreased mortality for both mother and neonate.[3] Prior to 1970, a prenatal diagnosis of pheochromocytoma was made in only approximately 25% of cases, and the mortality rate for both mother and neonate was around 50%.[4,5] The prenatal diagnosis rate rose to greater than 80% through the 1980s and 1990s, and decreased maternal and neonatal mortality rates were 6% and 15%, respectively.[4,6]The diagnosis of pheochromocytoma should be suspected in any pregnant woman who develops hypertension in the first trimester, paroxysmal hypertension, or hypertension that is unusually difficult to

  5. Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Lycopene

    OverviewThis section contains the following key information:Lycopene is a carotenoid, a natural pigment made by plants and various fruits and vegetables, including tomatoes, apricot, guava, and watermelon.Lycopene's absorption is improved with concurrent dietary fat intake.Lycopene inhibits androgen receptor expression in prostate cancer cells in vitro and, along with some of its metabolites, reduces prostate cancer cell proliferation and may modulate cell-cycle progression.Lycopene may also affect the insulin-like growth factor intracellular pathway in prostate cancer cells.Results from several in vitro and animal studies have indicated that lycopene may have chemopreventive effects for cancers of the prostate, skin, breast, lung, and liver; however, human trials have been inconsistent in their findings. Clinical trials utilizing lycopene in prostate cancer patients with various different clinical presentations (e.g., early stage, prostate-specific

  6. Neuroblastoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

    There are different types of treatment for patients with neuroblastoma. Different types of treatment are available for patients with neuroblastoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment. Children with neuroblastoma should have their treatment planned by a team of doctors with expertise in treating childhood cancer.Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with

  8. 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

  9. Unusual Cancers of Childhood Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Unusual Cancers of Childhood

    IntroductionFortunately, cancer in children and adolescents is rare, although the overall incidence of childhood cancer has been slowly increasing since 1975.[1] Children and adolescents with cancer should be referred to medical centers that have a multidisciplinary team of cancer specialists with experience treating the cancers that occur during childhood and adolescence. This multidisciplinary team approach incorporates the skills of the primary care physician, pediatric surgical subspecialists, radiation oncologists, pediatric medical oncologists/hematologists, rehabilitation specialists, pediatric nurse specialists, social workers, and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life.
