Comparison to Psychological, Medical and Emotional Influencing Communication and Achievement Factors to Oncogenetics Tests

Study Overview
=================
Brief Summary
-----------------
The purpose of the study was to analyze the psychological and emotional determinants of domestic dissemination of information about genetic risk of cancer and to compare the level of diffusion syndromes in breast/ ovarian cancer ( BRCA1 / BRCA2) and colon/endometrial ( HNPCC )

Detailed Description
-----------------
The risk associated with a genetic predisposition is among the various forms of risk, the strongest identifiable risk . It enables to offer people at risk an appropriate medical care (screening, prevention ) the clinical benefit is validated today. The person with whom a predisposing mutation has been identified must communicated its related information on the risk of cancer and the ability to perform genetic analysis. It appears that this dissemination of information is not always optimal, as shown in figures from the National Cancer Institute joined the project; the purpose of the study was to analyze the psychological and emotional determinants of domestic dissemination of information about genetic risk of cancer and to compare the level of diffusion syndromes in breast/ ovarian cancer ( BRCA1 / BRCA2) and colon/endometrial ( HNPCC )

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| intrafamilial disclosure rate | The intrafamilial disclosure rate assessed the number of relatives informed by the proband about the mutation (according to the proband) out of the number of relatives at risk of carrying the familial mutation. Relatives who were considered at risk were first, second, third or fourth-degree relatives, older than 18 years and related to the relevant side of the family or, if unknown, just related to the proband whatever the family side. | On average 1 year | 
| relatives' genetic targeted testing uptake rate | The relatives' genetic targeted testing uptake rate assessed the number of relatives considered by the proband to have taken up the genetic targeted testing out of the number of relatives informed by the proband. To assess the potential bias of the proband's perception of genetic targeted testing uptake by relatives, we compared the number of relatives who underwent genetic targeted testing according to the proband with the number of tests actually performed. This anonymous comparison was performed in a subset of the population within the geographic regional area of Montpellier where all analyses are centralized in a single laboratory. Probands were asked how many relatives living in the region underwent genetic testing and this number was compared with the information available from the University Laboratory of Montpellier. | On average 1 year |
