Purpose Preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND) practices for inherited predisposition to cancer are heterogeneous in industrialized countries. In France, permission to perform PGD/PND must be obtained from registered Multidisciplinary Prenatal Diagnosis Teams (MPDTs). The aim of this study was to determine French professionals' attitudes about the acceptability of PGD and PND for inherited predisposition to cancer. Methods A cross-sectional survey was performed, involving self-administered questionnaires mailed to all registered cancer geneticists (CGs; n = 123) and MPDTs (n = 47) in France. Results The response rates of CGs and MPDTs were 62% and 64%, respectively; 59% and 50% of the CGs had at least discussed PGD and PND, respectively, with their consultees during the previous year. When severe cancer is liable to occur in childhood with a high penetrance and no effective methods of prevention/treatment exist, high rates of acceptability of PGD/PND were recorded (> 80%). When cancer is liable to occur before the age of 50 years but not in childhood and some form of prevention/treatment is available that preserves quality of life, PGD was rated as acceptable by one MPDT (3.3%) and 10 CGs (13.2%), and PND was rated acceptable by nine CGs (11.8%). Most respondents agreed that the acceptability of PND/PGD depends on patients' family history of cancer and their reproductive history. Conclusion With the most severe forms of inherited cancer, no differences were observed between the acceptability to practitioners of PND and PGD, but with late-onset syndromes, there is still much uncertainty. Guidelines would help to standardize the practices of professionals handling these reproductive issues.

Prenatal diagnosis of molecular mutations can be of immense value, since diagnosis followed by genetic counselling provides the most appropriate approach to genetic diseases control and prevention. However, ethical, psychosocial and religious considerations hamper adoption of prenatal diagnosis in communities where termination of a pregnancy may not be acceptable. Recently, preimplantation genetic diagnosis has attracted considerable interest. This involves in vitro fertilization, followed by genetic disorder diagnosis using polar bodies or cells extracted from a blastomere stage. The normal blastomere is implanted in the womb and pregnancy proceeds naturally. If an abnormality is diagnosed, the blastomere is not implanted, thus preventing pregnancy with the affected fetus. This paper outlines the potential usefulness of preimplantation genetic diagnosis in the control and prevention of genetic disease in our part of the world
