Evidence-based advancements in breast cancer genetic counseling: a review.

PURPOSE

Understanding individuals at high risk of breast cancer, as well as patients and survivors, underscores the critical role of genetic counseling in the diagnosis and treatment of breast cancer.

METHODS

This systematic review adhered to the guidelines outlined in the Reporting Items for Systematic Review and Meta-Analysis (PRISMA). The review process was managed using Covidence systematic review software, facilitating data extraction according to predefined eligibility criteria by two independent reviewers. Quality appraisal and narrative synthesis were conducted following data extraction.

RESULTS

Out of 1089 articles screened, nineteen (19) studies met the inclusion criteria and were included in this review. These studies were categorized into categories based on their relevance to breast cancer genetic counseling. Rapid Genetic Counseling and Testing (RGCT): 3 studies (15.78%), racial differences: 2 studies (10.52%), limited health literacy: 4 studies (21.05%), breast cancer survivorship: 3 studies (15.78%), risk perceptions and cancer worry: 5 studies (26.31%) and telephone delivery and computer aid programs: 2 studies (10.52%) based on specific focus areas of each study in relation to breast cancer genetic counseling.

CONCLUSION

Genetic counseling has shown to improve client outcomes across the majority of reviewed studies, contributing to the advancement of evidence-based practice in this field. However, to further promote evidence-based advancements in breast cancer genetic counseling, it is imperative to pay close attention to potential sources of bias and uphold rigorous quality standards in future research endeavors.
