RESUMO

Despite research on BRCA1/2 mutation carriers attitudes towards preimplantation genetic diagnosis (PGD), considerably less is known about individuals' experience with its use. Through case reports of BRCA1/2 mutation carriers' thoughts on, and use of, PGD, this paper highlights how the option of PGD is experienced and negotiated in the context of reproductive and life-course goals. Drawing on qualitative interviews with 38 BRCA1/2 mutation carriers, this article focuses on a subsample of 10 interviewees who sought consultation for, and/or attempted, PGD, with in-depth reports of 3 cases and summary decisions of the remaining 7. Three couples decided against PGD, and one was deciding at the time of the interview. Interviewees discuss key aspects of their experience prior to, and going through, PGD for BRCA1/2, including potential challenges of becoming pregnant through PGD and of heightened pressure to achieve their reproductive goals more quickly. Despite considerable focus on ethical issues in screening embryos for mutations associated with adult-onset cancer risk, less attention has been paid to the technical, logistical, and related psychosocial issues. Narrative case reports may help individuals develop appropriate expectations of PGD for BRCA prepare for possibly challenging decisions and outcomes, and ultimately determine whether it is compatible with their reproductive goals.

RESUMO

BACKGROUND: Studies have shown that BRCA1/2 mutation carriers are interested in learning about reproductive options such as preimplantation genetic diagnosis (PGD) to prevent passing their risk onto their children. However, attitudes vary widely, and the procedure raises complex ethical and psychosocial issues. This complexity, plus the highly technical nature of PGD, makes it difficult to integrate PGD information into genetic counseling sessions that already cover probabilistic, emotionally charged risk information. METHODS: A total of 33 carriers of the BRCA1/2 mutation who were of reproductive age and had previously undergone genetic counseling viewed a tutorial regarding PGD and were interviewed concerning their attitudes toward PGD and preferences about how to include PGD information in genetic counseling. RESULTS: The majority of participants preferred to be briefly informed of the availability of PGD information, and to receive written materials regarding PGD, but with the option of deferring detailed discussion if they already believed themselves to be overloaded or perceived that PGD was not immediately relevant to their risk management and/or childbearing plans. For some individuals, the stress of testing temporarily interfered with information processing, producing states of cognitive avoidance ("in a fog," or "tuning out"). Some preferred to discuss PGD with a physician with whom they had an ongoing relationship (eg, obstetrician/gynecologist, primary care provider, or oncologist). CONCLUSIONS: Providers offering cancer genetic testing may consider indicating the availability of PGD information to their patients, while attending to the patients' level of interest and ability to absorb information. Research is needed to link patient responses to information overload with psychosocial outcomes (eg, distress, and quality of decision-making). Continuing medical education is needed to support providers in facilitating informed decisions regarding PGD.

RESUMO

Deleterious mutations in the BRCA1/BRCA2 genes elevate lifetime risk of breast and ovarian cancer. Each child of a mutation-positive parent has a 50% chance of inheriting it. Preimplantation genetic diagnosis (PGD) permits prospective parents to avoid the birth of a BRCA-mutation-positive child, introducing predictability into a process historically defined by chance. This investigation explored how BRCA1/2 mutation carriers understand genetic inheritance and consider a child's inheritance of a BRCA1/2 mutation, given the opportunities that exist to pursue PGD. Thirty-nine female and male BRCA1/2 mutation carriers of reproductive age were recruited from urban cancer and reproductive medical centers. Participants completed a standardized educational presentation on PGD and prenatal diagnosis, with pre- and posttest assessments. An interdisciplinary team of qualitative researchers analyzed data using grounded theory techniques. Participants expressed the belief that reproduction yields children with unique genetic strengths and challenges, including the BRCA1/2 mutation, family traits for which predictive tests do not exist, and hypothetical genetic risks. Participants expressed preference for biologically related children, yet stated their genetically "well" partner's lineage would be marred through reproductive merger, requiring the well partner to assume the burden of the BRCA1/2 mutation via their children. Participants expressed diverse views of genetically "well" partners' participation in family planning and risk management decisions. Pressure to use reprogenetic technology may grow as genetic susceptibility testing becomes more widely available. Work with individuals and couples across the disease spectrum must be attuned to the ways beliefs about genetic inheritance play into reproductive decision-making.
