[Informing the family: emotions and attitudes of oncogenetic counselees for familial breast/ovarian and/or colon cancer risk].

BACKGROUND

Transmission of oncogenetic information (TOI) by probands to their families is of major importance to organize medical prevention in his family. Little is known about the difficulties that the proband faces when he tries to endorse his "duty to warn".

METHODS

To characterize the barriers to TOI, a survey was performed, previously to the bioethic law of 2011, on a representative sample of 337 counselees seen in the last 10 years at the Centre Jean-Perrin Oncogenetics Department. A questionnaire comprising 97 items was prepared by experts and validated by a group of patients and health professionals. Nineteen Lickert-scale questions specially concerned TOI.

RESULTS

Analysis found two dimensions, one of emotions and one concerning communication attitudes. Both dimensions were negatively correlated (r=-0.34, P<10(-7)): high emotional levels limited communication attitudes. The probands' history of cancer was the main factor impacting TOI. TOI was more difficult for cancer patients than for healthy counselees (P=0.025). Delay since consultation and type of cancer risk had no bearing on TOI.

CONCLUSION

Cancer and its treatments seem to deeply affect patient's relatives and limit his capacity to involve his family into the oncogenetic inquiry. Measures are suggested to help ex-patients improve TOI.
