FRANCISCO, Oct. 12 , 2023 /PRNewswire/ --
Invitae (NYSE: NVTA), a leading medical genetics company,
today announced results of its collaborative study on universal
hereditary cancer genetic testing in all patients with breast
cancer in a rural population in the Annals of Surgical
Oncology. Conducted in collaboration with The Outer Banks
Hospital (TOBH) in North Carolina
from 2019 to 2022, the study analyzed the implementation of
universal hereditary cancer genetic testing in all patients with
breast cancer, as recommended by the American Society of Breast
Surgeons (ASBrS) guidelines in 2019. The results reaffirm
the previous findings of Whitworth et al. that universal
hereditary cancer genetic testing improves patient outcomes and
shows testing based de-escalation of therapy which may curtail
treatment costs.
In the study, all patients diagnosed with breast cancer were
offered hereditary cancer genetic testing and 91.4% underwent
testing and received results that could aid in their healthcare
journey. Approximately half of the patients (52.4%) met National
Comprehensive Cancer Network (NCCN) criteria while 45.8% did not
meet the NCCN criteria. Implementation of universal hereditary
cancer genetic testing in this rural healthcare system was
facilitated by genetics-trained clinicians who provided pretest
education and results disclosure, with treatment recommendations
discussed at multidisciplinary tumor boards. Of the patients who
underwent testing, 13% had a pathogenic (disease-causing) germline
variant (PGV) in one of 15 genes and the frequency of PGVs did
not differ between out of criteria and in criteria patients,
although in criteria patients had a larger proportion of high risk
variants than the out of criteria patients, consistent with
previous findings of Beitsch et al. Currently, NCCN criteria
restrict hereditary cancer genetic testing to a subset of patients
with breast cancer while these data provide further evidence
confirming the ASBrS recommendation of universal testing for
all patients with breast cancer as the standard of care.
"This study demonstrates the feasibility of implementing
universal hereditary cancer genetic testing for patients with
breast cancer in rural community practices," said Robert Nussbaum, M.D., chief medical officer at
Invitae. "The results reiterate in a real-world setting that
genetic testing changes management and treatment plans for these
patients, improving patient care."
Genetic testing-informed changes to clinical management,
including changes in surgery, radiation, surveillance and
clinical-follow up, occurred in 70% of patients. The majority of
patients (97%) reported that testing results were useful in shared
surgical decision-making and that knowledge of the results prior to
their primary therapy reinforced their choice for surgery.
"Our study provides a blueprint for implementing universal
hereditary cancer genetic testing in rural populations who
typically see disproportionate care due to access to services and
treatment," said Charles Shelton,
M.D., lead author of the study and radiation oncologist at TOBH.
"We demonstrate that germline-directed clinical management did not
lead to under- or overuse of radiation therapy or bilateral
mastectomy, thus demonstrating that universal testing enables
optimization of clinical care and reduces unnecessary healthcare
resource utilization."
