Filter by:This study will investigate the frequency, clinical phenotype, management and molecular genetic defects of heritable kidney cancer syndromes. Families with kidney cancer with known or suspected genetic basis will be enrolled. Affected individuals or individuals suspected of having a germline kidney cancer will undergo periodic clinical assessment and genetic analyses for the purpose of: 1) definition and characterization of phenotype, 2) determination of the natural history of the disorder, and 3) genotype/phenotype correlation. Genetic linkage studies may be performed in situations in which the genetic basis of the disorder has not been elucidated. This research will have a significant impact on the overall management of heritable kidney cancer syndromes patients and family members who are at risk for heritable kidney cancer syndromes. The study will ultimately facilitate the development of novel screening, prevention and treatment strategies for these individuals with the syndrome. In addition this study could have impact on the management of patients with personal and/or family history of heritable kidney cancer syndromes.
This study will investigate what causes hereditary leiomyomatosis renal (kidney) cell cancer, or HLRCC, and how the disease is related to the development of kidney tumors. Leiomyomas are benign (non-cancerous) tumors arising from smooth muscle. HLRCC can cause various health problems. Some people develop red bumps on their skin that can be painful at times. Some women with HLRCC can develop leiomyomas of the uterus. In some families, people with HLRCC develop kidney tumors. This study will try to determine: - What gene changes (mutations) cause HLRCC - What kind of kidney tumors develop in HLRCC and how they grow - What the chance is that a person with HLRCC will develop a kidney tumor People with known or suspected HLRCC (and their family members of any age) may be eligible for this study. This includes people in families in which one or more members has skin leiomyoma and kidney cancer; skin leiomyoma and uterine leiomyoma; multiple skin leiomyomas; kidney cancer and uterine leiomyomas, or kidney cancer consistent with HLRCC, including, but not limited to, collecting duct or papillary, type II. Candidates will be screened with a physical examination, family history, and, for affected family members, a review of medical records, including pathology slides and computed tomography (CT) or magnetic resonance imaging (MRI) scans. Participants will undergo tests and procedures that may include the following: - Review of medical records, x-rays, and tissue slides - Physical examination and family history - Skin examination - Gynecological examination for women - Interviews with a cancer doctor, cancer nurses, kidney surgeon, and genetic counselor - Blood tests for: 1. Genetic research to identify the gene responsible for HLRCC 2. Evaluation of liver, kidney, heart, pancreas, and thyroid function 3. Complete blood count and clotting profile 4. Pregnancy test for pre-menopausal women 5. PSA test for prostate cancer in men over age 40 - CT or MRI scans (for participants 15 years of age and older only) - Skin biopsy (surgical removal of a small sample of skin tissue) - Cheek swab or mouth rinse to collect cells for genetic analysis - Medical photographs of lesions - Questionnaire When the tests are completed, participants will discuss the results with a doctor and possibly a genetic nurse or genetic counselor. The genetic findings will not be revealed to participants because their meaning and implications may not yet be understood. Participants may be asked to return to NIH from every 3 months to every 3 years, depending on their condition, for follow-up examinations and tests.
