RESUMO
PURPOSE: Germline genetic testing (GT) is recommended for all patients with pancreatic ductal adenocarcinoma (PDAC), but the traditional clinical genetics infrastructure is limited in addressing the unique needs of this population. We describe the integration of point of care (POC) GT into routine clinical practice for all patients with PDAC at an academic medical center. METHODS: We developed a clinical POC workflow that leverages electronic health record (EHR) tools and behavioral nudges to enhance the sustainability and scalability of our previously described research-based POC model. For each of the research and clinical POC cohorts, we calculated the percentage of eligible patients who underwent GT. We used Wilcoxon rank-sum and Pearson's chi-squared tests to compare patients who did and did not undergo GT. We conducted surveys among oncology clinicians to evaluate the acceptability, appropriateness, and feasibility of the clinical POC model. RESULTS: The research POC cohort included 905 patients, of whom 694 (76.7%) underwent GT. The clinical POC cohort included 148 patients, of whom 126 (85.1%) underwent GT. Patients who underwent GT in the research POC cohort were significantly younger (median age, 67.0 v 70.9 years; P = .031) and more likely to be White (82.1% v 68.7%; P < .001) and commercially insured (41.8% v 28.0%; P < .001) compared with those who did not; there were no significant differences between GT groups in the clinical POC cohort. Oncology clinicians found the clinical POC model to be acceptable (mean 4.4/5), appropriate (4.6/5), feasible (4.0/5), and have a positive impact on their patients (4.9/5). CONCLUSION: A clinical POC model leveraging EHR tools and behavioral nudges is acceptable, appropriate, feasible, and associated with a >85% GT rate among patients with PDAC.
RESUMO
PURPOSE: Genetic testing may alter clinical management for individuals with metastatic prostate cancer by identifying additional therapies. Traditional counseling models are unlikely to enable time-sensitive therapeutic decision-making. This study aimed to determine the feasibility and clinical impact of an alternative hereditary genetic testing model. MATERIALS AND METHODS: As part of a multicenter, single-arm prospective trial, individuals with advanced prostate cancer were referred by their oncologist for testing of 14 genes associated with hereditary prostate cancer. Pretest education (brochure and video) was provided in the oncology clinic. Questionnaires assessing participant satisfaction with both pretest education and decision to undergo genetic testing were collected. A genetic counselor contacted participants by phone to obtain family history and discuss results. Medical records were queried to determine whether a change in clinical management was discussed. RESULTS: Of 501 participants consented to germline analysis, 51 (10.2%) had at least 1 pathogenic/likely pathogenic variant. Change in treatment was discussed with 22/48 (45.8%) of eligible participants who tested positive. Feasibility of this model was assessed by participant satisfaction and turnaround time. Average±SD satisfaction with the pretest education (15.5±2.2, 4-20 scale) and with the decision to undergo genetic testing (17.1±2.9, 4-20 scale) were both high. Results were returned 20 days (median) after sample collection. CONCLUSIONS: Oncologist-initiated germline genetic testing in collaboration with a genetic counselor is a feasible approach to testing advanced prostate cancer patients with impactful clinical actionability. The testing model and educational material serve as resources to clinicians treating prostate cancer patients.

PURPOSE: This study aimed to evaluate uptake and follow-up using internet-assisted population genetic testing (GT) for BRCA1/2 Ashkenazi Jewish founder pathogenic variants (AJPVs). METHODS: Across 4 cities in the United States, from December 2017 to March 2020, individuals aged ≥25 years with ≥1 Ashkenazi Jewish grandparent were offered enrollment. Participants consented and enrolled online with chatbot and video education, underwent BRCA1/2 AJPV GT, and chose to receive results from their primary care provider (PCP) or study staff. Surveys were conducted at baseline, at 12 weeks, and annually for 5 years. RESULTS: A total of 5193 participants enrolled and 4109 (79.1%) were tested (median age = 54, female = 77.1%). Upon enrollment, 35.1% of participants selected a PCP to disclose results, and 40.5% of PCPs agreed. Of those tested, 138 (3.4%) were AJPV heterozygotes of whom 21 (15.2%) had no significant family history of cancer, whereas 86 (62.3%) had a known familial pathogenic variant. At 12 weeks, 85.5% of participants with AJPVs planned increased cancer screening; only 3.7% with negative results and a significant family history reported further testing. CONCLUSION: Although continued follow-up is needed, internet-enabled outreach can expand access to targeted GT using a medical model. Observed challenges for population genetic screening efforts include recruitment barriers, improving PCP engagement, and increasing uptake of additional testing when indicated.

PURPOSE: Engaging primary care providers (PCPs) in BRCA1/2 testing and results disclosure would increase testing access. The BRCA Founder OutReach (BFOR) study is a prospective study of BRCA1/2 founder mutation screening among individuals of Ashkenazi Jewish descent that sought to involve participants' PCPs in results disclosure. We used quantitative and qualitative methods to evaluate PCPs' perspectives, knowledge, and experience disclosing results in BFOR. METHODS: Among PCPs nominated by BFOR participants to disclose BRCA1/2 results, we assessed the proportion agreeing to disclose. To examine PCP's perspectives, knowledge, and willingness to disclose results, we surveyed 501 nominated PCPs. To examine PCPs' experiences disclosing results in BFOR, we surveyed 101 PCPs and conducted 10 semi-structured interviews. RESULTS: In the BFOR study overall, PCPs agreed to disclose their patient's results 40.5% of the time. Two hundred thirty-four PCPs (46.7%) responded to the initial survey. Responding PCPs were more likely to agree to disclose patients' results than non-responders (57.3% vs. 28.6%, p<0.001). Among all respondents, most felt very (19.7%) or somewhat (39.1%) qualified to share results. Among PCPs declining to disclose, insufficient knowledge was the most common reason. In multivariable logistic regression, feeling qualified was the only variable significantly associated with agreeing to disclose results (OR 6.53, 95% CI 3.31, 12.88). In post-disclosure surveys (response rate=55%), PCPs reported largely positive experiences. Interview findings suggested that although PCPs valued the study-provided educational materials, they desired better integration of results and decision support into workflows. CONCLUSION: Barriers exist to incorporating BRCA1/2 testing into primary care. Most PCPs declined to disclose their patients' BFOR results, although survey respondents were motivated and had positive disclosure experiences. PCP training and integrated decision support could be beneficial. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03351803), November 24, 2017.

PURPOSE: To address demands for timely germline information to guide treatments, we evaluated experiences of patients with ovarian, pancreatic, and prostate cancer with a mainstreaming genetic testing model wherein multigene panel testing was ordered by oncologists with standardized pretest patient education, and genetic counselors delivered results and post-test genetic counseling via telephone. METHODS: Among 1,203 eligible patients, we conducted a prospective single-arm study to examine patient uptake and acceptability (via self-report surveys at baseline and three weeks and three months following result return) of this mainstreaming model. RESULTS: Only 10% of eligible patients declined participation. Among 1,054 tested participants, 10% had pathogenic variants (PV), 16% had variants of uncertain significance (VUS), and 74% had no variant identified (NV). Participants reported high initial acceptability, including high satisfaction with their testing decision. Variability over time in several outcomes existed for participants with PV or NV: those with NV experienced a temporary increase in depression (pTime < 0.001; pTime2 < 0.001), and those with PV experienced a small increase in genetic testing distress (p = 0.03). Findings suggested that result type, sex, and cancer type were also associated with outcomes including clinical depression and uncertainty. CONCLUSION: This mainstreaming model may offer a feasible approach for extending access to germline genetic information.

BACKGROUND: Evidence is needed regarding effective incentive strategies to increase clinician survey response rates. Cash cards are increasingly used as survey incentives; they are appealing because of their convenience and because in some cases their value can be reclaimed by investigators if not used. However, their effectiveness in clinician surveys is not known. In this study within the BRCA Founder OutReach (BFOR) study, a clinical trial of population-based BRCA1/2 mutation screening, we compared the use of upfront cash cards requiring email activation versus checks as clinician survey incentives. METHODS: Participants receiving BRCA1/2 testing in the BFOR study could elect to receive their results from their primary care provider (PCP, named by the patient) or from a geneticist associated with the study. In order to understand PCPs' knowledge, attitudes, experiences and willingness to disclose results we mailed paper surveys to the first 501 primary care providers (PCPs) in New York, Boston, Los Angeles and Philadelphia who were nominated by study participants to disclose their BRCA1/2 mutation results obtained through the study. We used alternating assignment stratified by city to assign the first 303 clinicians to receive a $50 up-front incentive as a cash card (N = 155) or check (N = 148). The cash card required PCPs to send an activation email in order to be used. We compared response rates by incentive type, adjusting for PCP characteristics and study site. RESULTS: In unadjusted analyses, PCPs who received checks were more likely to respond to the survey than those who received cash cards (54.1% versus 41.9%, p = 0.046); this remained true when we adjusted for provider characteristics (OR for checks 1.61, 95% CI 1.01, 2.59). No other clinician characteristics had a statistically significant association with response rates in adjusted analyses. When we included an interaction term for incentive type and city, the favorable impact of checks on response rates was evident only in Los Angeles and Philadelphia. CONCLUSIONS: An up-front cash card incentive requiring email activation may be less effective in eliciting clinician responses than up-front checks. However, the benefit of checks for clinician response rates may depend on clinicians' geographic location. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT03351803 ), November 24, 2017.

Demand for cancer genetic counseling has grown rapidly in recent years as germline genomic information has integrated into cancer care. There are currently an insufficient number of genetic counselors (GC) to address genetic testing need through traditional pre- and post-test counseling. Alternative genetic counseling frameworks, discussed here, are under study to increase access to genetic testing while optimizing the skillsets of existent master's-trained GCs.

PURPOSE: Germline mutations in the homologous recombination genes BRCA1, BRCA2, and PALB2 confer an increased risk for pancreatic ductal adenocarcinoma (PDAC). Tumors associated with mutations in homologous recombination genes are sensitive to DNA-damaging agents. We retrospectively studied patients with resected PDAC and a pathogenic germline mutation in one of these three genes. The planned analyses included overall survival (OS) and changes therein when platinum chemotherapy was used in the perioperative setting. MATERIALS AND METHODS: Thirty-two individuals with pathogenic germline mutations in BRCA1, BRCA2, or PALB2 and resected PDAC (mutation positive) were matched in a 1:2 fashion to patients who were noncarriers or untested (mutation negative) by age, year of diagnosis, stage, and sex. Patients were identified via one of two available databases at University of Pennsylvania: the Basser Center for BRCA Registry or the electronic medical record. The primary outcome was OS. RESULTS: Patients in the mutation-positive group had a median OS (mOS) of 46.6 months; those in the mutation-negative group had an mOS of 23.2 months (hazard ratio [HR], 0.49; 95% CI, 0.27 to 0.88). With platinum exposure in the perioperative setting, mOS in the mutation-positive group had not yet been met versus a mOS of 23.1 months in the mutation-negative group (HR, 0.12; 95% CI, 0.01 to 1.00). When neither group was treated with platinum, there was no significant OS difference between groups (HR, 0.52; 95% CI 0.12 to 2.24). Patients in the mutation-positive group who received perioperative treatment with platinum had a trend toward improved mOS compared with those who did not (HR, 0.15; 95% CI, 0.02 to 1.23; P = .07). CONCLUSION: Platinum-based chemotherapy may confer a survival benefit in patients with resected PDAC and a pathogenic germline BRCA1, BRCA2, or PALB2 mutation. Knowledge of a germline mutation may be important to determine best choice of perioperative chemotherapy.
