遗传性平滑肌瘤病肾细胞癌 - 遗传原因和肾癌易感性研究

2026年11月3日 更新者：National Cancer Institute (NCI)

遗传性平滑肌瘤病肾细胞癌 (HLRCC)：疾病基因的鉴定和肾癌易感性的表征

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.

详细说明

Background:

  • Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) is a rare autosomal dominantly inherited disorder which confers susceptibility to develop cutaneous and uterine leiomyomas and renal cell carcinoma.
  • HLRCC is caused by mutations in the Krebs cycle enzyme, fumarate hydratase localized on chromosome 1q42.3-q43.

Objectives:

  • Define the risk of developing renal cancer, cutaneous leiomyoma and uterine leiomyoma in this hereditary cancer syndrome
  • Define the types and characteristics (including patterns of growth) of renal cancer associated with HLRCC
  • Determine the incidence and characteristics of HLRCC-associated fumarate hydratase gene mutations
  • Determine genotype/phenotype correlations
  • Determine if other genes cause HLRCC

Eligibility:

  • Individuals that meet one or more of the following criteria:

  • Suspected or known to have phenotype or genotype suggestive of Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome (HLRCC), such as:

    • Cutaneous leiomyoma and kidney cancer
    • Cutaneous leiomyoma and uterine leiomyoma
    • Multiple cutaneous leiomyoma
    • Kidney cancer and uterine leiomyomata

or

-Renal tumor histology consistent with HLRCC including, but not limited to: Collecting Duct and/or Papillary, Type II

or

-Are a relative (related by blood) of an individual with a confirmed or suspected diagnosis of HLRCC

Design:

  • These rare biological families will be recruited to genetically confirm diagnosis, determine size and location of renal tumors, size at presentation, growth rate and metastatic potential of renal tumors.
  • Genetic testing will be offered to gain appreciation of the effect of mutations on the relative activity of various germline and somatic mutations.
  • We will determine if there is a relationship between mutation and disease phenotype.
