Multivariate risk models are commonly used in clinical practice to estimate a woman's lifetime risk for breast cancer and assist in implementation of appropriate screening and risk reduction strategies. More recently, breast cancer polygenic risk scores (PRS) have been derived and integrated into these models to further improve risk estimation. While breast cancer PRS have been offered by two clinical diagnostic laboratories since 2017, little is known about the extent to which genetic counselors are ordering breast cancer PRS or incorporating the results into patient management. This study surveyed U.S. cancer genetic counselors from October 2019 to January 2020 to identify and understand their current practices with breast cancer PRS, to determine the impact of breast cancer PRS on patient management, and to anticipate future genetic counselor practices with breast cancer PRS. Fewer than half of respondents (43%, 51/120) had ordered breast cancer PRS and approximately one‐third (35%, 16/46) reported that the PRS had changed their medical management recommendations. The majority of cancer genetic counselors had not ordered PRS, most commonly due to (a) lack of clinical guidelines (90%, 60/67), (b) insufficient evidence of clinical utility (88%, 59/67), and (c) lack of availability for patients of non‐European ancestry (70%, 47/67). Of genetic counselors who had not ordered breast cancer PRS, only 10% (7/68) did not believe they would order PRS in the future. This is the first study to characterize genetic counselors’ experiences with breast cancer PRS. Results from this study indicate that although breast cancer PRS have been clinically available for patients for several years, most cancer genetic counselors are not yet convinced they are ready to be incorporated into patient care.
Background
As survivorship care plan (SCP) use among childhood cancer survivors and their families has not been extensively researched, we report on their experiences with receiving an SCP after the completion of therapy.
Methods
Eligible patients had acute lymphoblastic leukemia, completed therapy, and had no evidence of disease at enrollment. Patients aged 7 or older (
N
= 13) and at least one parent (
N
= 23 for 20 total patients) were surveyed and completed assessments at enrollment (Time 1, T1), SCP delivery (Time 2, T2), and follow-up (Time 3, T3) (retention 90.9%). Surveys assessed the delivery process and SCP format. McNemar tests were used to assess change from T2-T3.
Results
Satisfaction with the SCP was generally high among parents. At T1 the majority of parents (69.6%) thought the SCP should be delivered after treatment but by T3 most preferred the plan to be delivered before the end of treatment (60.9%). While 95.7% of parents intended to share their child’s SCP with another provider, family, or school at T2, only 60.9% had done so by T3 (
P
< 0.01). At both T2 and T3, 100% of parents agreed that the SCP would help make decisions about their child’s future health care. Most patients at T3 (83.3%) felt they had learned something new from their SCP.
Conclusions
Pediatric oncology patients and families feel SCPs are useful and will help them make decisions about health care in the future.

Adolescent and adult survivors of pediatric ALL require additional weight management resources such as targeted counseling for physical activity and dietician support both early in treatment and after the end of their therapy. Female survivors may need additional guidance to develop healthy eating practices and to participate in exercise programs.
