Timely Cancer Genetic Counseling and Testing for Young Women With Breast Cancer: Impact on Surgical Decision-making for Contralateral Risk-reducing Mastectomy

PURPOSE: Genetic testing (GT) can identify individuals with pathogenic variants (PV) in breast cancer (BC) predisposition genes, who may consider contralateral risk-reducing mastectomy (CRRM). We report on CRRM rates in young women newly diagnosed with BC who received GT through a multidisciplinary clinic. METHODS: Clinical data was reviewed for patients seen between November 2014 and June 2019. Patients with non-metastatic, unilateral BC diagnosed at age ≤45 and completed GT prior to surgery were included. Associations between surgical intervention and age, BC stage, family history, and GT results were evaluated. RESULTS: Of the 194 patients, 30 (15.5%) had a PV in a BC predisposition gene (ATM , BRCA1, BRCA2, CHEK2, NBN, NF1), with 66.7% in BRCA1 or BRCA2. Of 164 (84.5%) uninformative results, 132 (68%) were negative and 32 (16.5%) were variants of uncertain significance (VUS). Overall, 67 (34.5%) had CRRM, including 25/30 (83.3%) PV carriers and 42/164 (25.6%) non-carriers. Only a positive test result was associated with CRRM (p < 0.01). For the 164 with uninformative results, CRRM was not associated with age (p = 0.23), a VUS, (p = 0.08), family history (p = 0.19), or BC stage (p = 0.10). CONCLUSION: In this cohort of young women with BC, the identification of a PV in a BC predisposition gene was the only factor associated with the decision to pursue CRRM. Thus, incorporation of genetic services in the initial evaluation of young patients with a new BC could contribute to the surgical decision-making process.

Telephone versus in-person genetic counseling for hereditary cancer risk: Patient predictors of differential outcomes

Purpose Telegenetics has become the predominant mode of cancer genetic counseling during the COVID-19 pandemic. We sought to identify potential patient-level contraindicators for telegenetic genetic counseling. Methods We analyzed post-counseling (pre-result disclosure) follow-up data from a randomized noninferiority trial of a telephone genetic counseling versus usual care genetic counseling. Among 669 randomized participants, 600 completed pre-test counseling and 568 completed a 2-week follow-up assessment before receiving test results. In this analysis, we focused on genetic counseling outcomes (knowledge, decisional conflict, and distress). In multivariate models controlling for bivariate predictors of these outcomes, we tested our a priori hypotheses that pre-counseling numeracy, perceived stress, and race/ethnicity would moderate the outcomes of telephone genetic counseling versus usual care. Results Only numeracy significantly moderated associations between mode of genetic counseling and outcomes. Higher numeracy was associated with higher post-counseling knowledge following telephone genetic counseling ( p < 0.001), but not usual care ( p = 0.450). Higher numeracy was also associated with lower distress following telephone genetic counseling ( p = 0.009) but not usual care ( p = 0.16). Neither perceived stress nor race/ethnicity exhibited differential impacts on telephone genetic counseling versus usual care ( ps > 0.20). Conclusion Although high numeracy was associated with higher levels of knowledge following telegenetic counseling, we did not identify any clinically significant patient-level contraindicators for telegenetic counseling. These results lend further confidence to the broad use of telegenetics.

Factors Influencing Patient Preferences for Telehealth Cancer Genetic Counseling During the COVID-19 Pandemic

PURPOSE: With onset of the COVID-19 pandemic, telehealth became the primary modality for health care appointments. This study examined patient experiences with and preferences for telehealth at a cancer genetic counseling clinic throughout the first 6 months of the pandemic (March-August 2020). METHODS: An anonymous survey assessed patient demographics; usage and prior experience with technology; emotional responses, technical experiences, and satisfaction with the telehealth appointment (via the Genetic Counseling Satisfaction Scale and Visit-Specific Satisfaction Questionnaire); preference for future telehealth; and recommendation of telehealth to others. RESULTS: Among 380 respondents, most were highly satisfied with the telehealth appointment (with 65.6% and 66.4% of participants completing the Genetic Counseling Satisfaction Scale and Visit-Specific Satisfaction Questionnaire, respectively). Multivariable analyses indicated several notable findings. Adjusting for relevant covariates, participants with less education felt significantly more concerned about telehealth than those with highest educational attainment. Participants age 40-69 years were generally more comfortable, relieved, and grateful that their appointment was scheduled as telehealth than were those older than 70 years. Women were marginally more relieved and grateful for telehealth appointments than men. As the pandemic progressed, significantly more participants were highly satisfied with their telehealth appointment and participants trended toward having greater preferences for future telehealth use. Most participants (78.6%) would recommend telehealth to others, although 50.8% preferred future in-person appointments. CONCLUSION: As the pandemic progressed, patients expressed increasing preferences for and satisfaction with telehealth. Service delivery models that incorporate individual patient preferences should be developed with special consideration to factors such as age, sex, and education level.

Development and Validation of an Italian Adaptation of the Psychosocial Aspects of Hereditary Cancer Questionnaire

Individuals that attend cancer genetic counseling may experience test-related psychosocial problems that deserve clinical attention. In order to provide a reliable and valid first-line screening tool for these issues, Eijzenga and coworkers developed the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire. The aim of this work was to develop an Italian adaptation of the PAHC (I-PACH). This prospective multicenter observational study included three stages: (1) development of a provisional version of the I-PAHC; (2) pilot studies aimed at testing item readability and revising the questionnaire; and (3) a main study aimed at testing the reliability and validity of the final version of the I-PAHC with the administration of a battery comprising measures of depression, anxiety, worry, stress, and life problems to 271 counselees from four cancer genetic clinics. Adapting the original PAHC to the Italian context involved adding two further domains and expanding the emotions domain to include positive emotions. While most of the items were found to be easy to understand and score, some required revision to improve comprehensibility; others were considered irrelevant or redundant and therefore deleted. The final version showed adequate reliability and validity. The I-PAHC provides comprehensive content coverage of cancer genetic-specific psychosocial problems, is well accepted by counselees, and can be considered a sound assessment tool for psychosocial issues related to cancer genetic counseling and risk assessment in Italy.

The impact of converting to telehealth for cancer genetic counseling and testing during the COVID-19 pandemic.

e13612 Background: The COVID-19 outbreak in March 2020 resulted in the shift to telemedicine for many specialties including cancer genetic counseling (GC). We sought to understand the impact that converting GC services to telehealth (TH) would have on patient acceptance of recommended genetic testing, time to completion of testing, and time to follow-up GC consultation. Methods: Data analyzing GC in-patient vs. TH consultations were collected using both electronic medical record as well as a laboratory’s testing portal. Statistical analysis was performed using R statistical software. The rates of patient agreement to genetic testing and sample success, along with the time to report availability and to GC follow-up visit was compared between traditional in-person visits and TH visits during the COVID-19 pandemic. In-person visits from March -July 2019 were compared with date matched visits from March -July 2020, when all visits had been converted to TH. Patients who received an in-person consultation received a blood draw on the day of their appointment while TH patients were asked to mail a saliva sample back to the testing laboratory. Results: An analysis of a case-matched cohort between 2019 in-person new visits (n = 30) and 2020 TH new visits (n = 48) was performed. There was not a significant difference in rate of consent to suggested testing between in-person (93.3%) and TH (91.2%) (p = 0.29), though a few TH patients who consented failed to submit a sample (% tested = 93.3% vs. 85.4%, p = 0.01). TH patients had a longer time between their initial consult and when the test report was generated with average turn-around time increasing from 14.33 to 33.82 days (p < 0.1). There was no increase in time from initial consultation to follow up GC appointments (70.46 vs. 75.96 days, p = 0.74) for TH and in-person, respectively. Conclusions: Our data shows that during COVID-19, TH allowed patients to access GC with no significant differences in the length of time between initial consultation and follow up appointments. The type of GC received did not greatly influence a patient’s willingness to consent to testing, despite challenges related to the COVID-19 pandemic, indicating that TH services may be an acceptable substitute. However, TH services are not without their limitations as time between the initial appointment and receipt of test results was significantly longer and sample failure rates were higher. We postulate that the delay was due to the time it took to ship the saliva kit, have the patient collect the sample at home, and return the specimen back to the lab rather than the immediate blood draw that occurs during the in-person visit. The higher sample failure rate seen in TH is likely due to the differences between blood and saliva collections. Additional research is needed to fully understand the outcomes observed in this study in order to assist in developing the most effective strategies for cancer genetic TH services.

Identification of a Novel Pathogenic Rearrangement Variant of the APC Gene Associated with a Variable Spectrum of Familial Cancer

Familial adenomatous polyposis (FAP) is an autosomal-dominant condition characterized by the presence of multiple colorectal adenomas, caused by germline variants in the adenomatous polyposis coli (APC) gene. More than 300 germline variants have been characterized. The detection of novel variants is important to understand the mechanisms of pathophysiology. We identified a novel pathogenic germline variant using next-generation sequencing (NGS) in a proband patient. The variant is a complex rearrangement (c.422+1123_532-577 del ins 423-1933_423-1687 inv) that generates a complete deletion of exon 5 of the APC gene. To study the variant in other family members, we designed an endpoint PCR method followed by Sanger sequencing. The variant was identified in the proband patient’s mother, one daughter, her brother, two cousins, a niece, and a second nephew. In patients where the variant was identified, we found atypical clinical symptoms, including mandibular, ovarian, breast, pancreatic, and gastric cancer. Genetic counseling and cancer prevention strategies were provided for the family. According to the American College of Medical Genetics (ACMG) guidelines, this novel variant is considered a PVS1 variant (very strong evidence of pathogenicity), and it can be useful in association with clinical data for early surveillance and suitable treatment.
