About this study

Official title: A Population Based Study of Genetic Predisposition and Gene-Environment Interactions in Ovarian Cancer in East Anglia, Oxford, Trent and West Midlands

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This study is looking at genetic susceptibility for cancer and interactions between genes and the environment in patients with ovarian cancer.

Read the detailed description

OBJECTIVES:

  • To obtain epidemiological information and biological material on a population-based series of ovarian cases.
  • To define the proportion of ovarian cancer incidence attributable to mutations in known predisposing genes (e.g., BRCA1 and BRCA2).
  • To determine the risk associated with predisposing mutations by examining the cancer risks in relatives of patients who are shown to be carriers.
  • To examine the effect of nongenetic risk factors in mutation carriers.
  • To determine the pathological and clinical characteristics of ovarian cancers occurring in BRCA1/2 mutation carriers as compared with that in noncarriers.
  • To establish whether mutations at other loci may predispose to ovarian cancer by comparing the frequency of alterations in ovarian cancer patients with that in cancer-free controls identified through the European Prospective Investigation of Cancer (EPIC) study.

OUTLINE: This is a multicenter study.

Patients complete an epidemiological questionnaire. The questionnaire will request identifying information on the patient's first-degree relatives.

Blood samples are collected from patients. DNA is extracted from these blood samples and from samples collected from cancer-free control participants in MREC-SEARCH-CONTROL as well as from additional controls through the European Prospective Investigation of Cancer (EPIC) study (a population based study of diet and health based in Norfolk, East Anglia). DNA samples are analyzed for polymorphisms of low penetrance cancer susceptibility genes.

In addition to the ovarian cancer patients recruited for this study, patients with breast, endometrial, prostate, colorectal, bladder, kidney, pancreatic, brain and esophageal cancer, malignant melanoma, and lymphoma cancer are recruited in the following related clinical trials: MREC-SEARCH-BREAST, MREC-SEARCH-ENDOMETRIAL, MREC-SEARCH-PROSTATE, MREC-SEARCH-COLORECTAL, and MREC-SEARCH-CANCER.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acquisition of epidemiological information and biological material

  2. Proportion of ovarian cancer incidence attributable to mutations in known predisposing genes (e.g., BRCA1 and BRCA2)

  3. Risk associated with predisposing mutations

  4. Effect of nongenetic risk factors in mutation carriers

  5. Pathological and clinical characteristics of ovarian cancers occurring in BRCA1/2 mutation carriers as compared with that in noncarriers

  6. Exploration of mutations at other loci that may predispose to ovarian cancer

Questions about this trial

What is this clinical trial studying?

An observational study of Ovarian Cancer, run by Cancer Research UK at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 26 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acquisition of epidemiological information and biological material. The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2013.
