Increasing referral of at-risk women for genetic counseling and BRCA testing using a screening tool in a community breast imaging center.

BACKGROUND: Genetic evaluation and testing for hereditary breast and ovarian cancer (HBOC) remain suboptimal. The authors evaluated the feasibility of using a screening tool at a breast imaging center to increase HBOC assessment referrals. METHODS: A brief questionnaire based on the National Comprehensive Cancer Network HBOC genetic counseling referral guidelines was developed and added to the standard intake forms of patients undergoing mammography at a community breast imaging center from 2012 through 2015. Patients who met the criteria in the guidelines were referred for genetic counseling. RESULTS: A total of 34,851 patients were screened during the study period, and 1246 (4%) patients were found to be eligible for referral; 245 of these patients made a genetic counseling appointment, and 142 patients received genetic counseling. Forty patients (28%) had a personal history of breast cancer but were not previously tested. Following counseling, 105 patients were tested for BRCA1/2. Eight patients (8%) tested positive for a pathogenic mutation and nine (9%) had a variant of unknown significance. Although they tested negative, many patients met the criteria to add breast magnetic resonance imaging to their screening due to greater than 20% lifetime breast cancer risk based on their family cancer history. This study led to improved clinical risk management in 67% of the patients who underwent genetic counseling. CONCLUSIONS: This study shows that large-scale screening of patients for HBOC syndromes at time of breast imaging is practical and highly feasible. The screening tool identified women with actionable BRCA1/2 mutations and mutation-negative but high-risk women, leading to significant changes in their risk management; these women would otherwise have been missed. LAY SUMMARY: Hereditary breast and ovarian cancer (HBOC) caused by pathogenic mutations in breast cancer genes (BRCA1/BRCA2) increase an individual's lifetime risk of getting HBOC. Identifying these high-risk individuals and using proven preventive clinical risk management strategies can significantly reduce their lifetime risk of HBOC. Using an innovative family cancer history questionnaire, 34,000 women were screened at a community breast imaging center, and genetic counseling and testing were provided to eligible women from the screening. Several women at high risk for HBOC were identified and this led to positive clinical risk management changes. These women would have been missed if not for intervention.

Application of the ACMG/NSGC genetic referral guidelines for hereditary renal cell carcinoma at the University of Miami, from 2014 to 2017.

Identifying hereditary syndromes among patients with renal cell carcinoma (RCC) is essential for surveillance of affected individuals and their at-risk family members and for treatment optimization. We conducted a chart review to determine the percentage of patients with RCC who were seen at the University of Miami Health System (UHealth), and met the American College of Medical Genetics (ACMG) and the National Society of Genetic Counselors (NSGC) genetic referral criteria at the University of Miami. Subsequently, we determined the percentage of those who went on to receive genetic evaluation. Patients selected by International Classification of Diseases (ICD) 9/10 codes corresponding to kidney cancer who were at least 18 years of age at the time of diagnosis were included in the study. We included a total of 1443 patients in the final analysis, and after exclusion of charts with incorrect ICD codes, insufficient clinical data, unknown pathology, and patients who were not seen. We used chi-square analysis, ANOVA, and t-test. Of 1443 charts reviewed, 65.7% were male and 34.3% were female. 47.7% self-identified as White, 39.2% as Hispanic, 9.1% as Black, and 4.0% as "other." The mean age of RCC diagnosis was 60.0 ± 12.4 years old. In total, 47.0% of patients met ACMG/NSGC referral criteria for genetic evaluation. Of those, only 4.2% had documented genetic assessment. This study showed a low adherence to ACMG/NSGC genetic referral guidelines at our institution and a need for increasing patients' and practitioners' awareness about the significance of genetic assessment for RCC patients and their family members.

Young-onset colorectal cancer in the North East of Scotland: survival, clinico-pathological features and genetics.

BACKGROUND: Colorectal cancer (CRC) in patients aged under 55 years is on the rise, constituting approximately 10% of cases. Our aim was to determine the survival and clinico-pathological details of young-onset CRC (yCRC), as well as audit the referral rate to genetic services and thus establish the incidence of inherited cancer syndromes. METHODS: A retrospective case note review was conducted for patients aged under 55 years who were diagnosed with CRC between 2005 and 2015 in the North East of Scotland. Cases were identified by pathology records and data was obtained from patient notes. Analysis was performed using SPSS version 25 (IBM, New York, USA) to produce Kaplan-Meier survival estimates, descriptive statistics and markers predictive for genetic referral. RESULTS: Data from 345 patients (age range 22-54 years) were identified. The one year, five year and overall survival rates were found to be 89, 63 and 55%, respectively. Most patients (61%) presented with advanced disease. Of 201 patients that met criteria for genetic referral, only 93 (46%) were referred to genetic services. Microsatellite instability (MSI) was identified in 14% of those referred. CONCLUSION: Survival in yCRC was found to be better than that in later onset disease, despite higher rates of advanced disease. Patients were under-referred to genetic services, where a significant proportion were found to be MSI positive and investigated for Lynch syndrome.

The Impact of Angelina Jolie (AJ)'s Story on Genetic Referral and Testing at an Academic Cancer Centre in Canada.

In May 2013, Angelina Jolie revealed to the media that she had undergone preventive double mastectomy after testing positive for a BRCA1 gene mutation. Media coverage has been extensive, but it is not clear how such a personal story affected the public and cancer genetics clinics. We conducted a retrospective review using data from the clinical database of the Familial Cancer Program at our centre. The impact of Ms. Jolie's story on genetic counseling referrals and the appropriateness of such referrals were assessed and reported. The number of women referred for genetic counseling increased by 90 % after 6 months and remained high one year after AJ's story with an increase of 88 % from baseline. The number of women who qualified for genetic testing increased by 105 % after 6 months; this increase persisted but was somewhat lower after one year with an increase of 68 % from baseline. Furthermore the number of BRCA1/2 carriers identified increased by 110 % after 6 months and by 42 % after one year.The effect of Mrs. Jolie's story persisted one year after its release; however in the latter half of the year, the hereditary cancer risk of referred women was significantly lower than initially observed. The next challenge for our health care system will not only be to meet the increased demand for cancer genetic services in our region, but also to ensure that referrals and hence use of genetic counseling resources are appropriate.

Referral, Genetic Counselling, and BRCA Testing in the Manitoba High-Grade Serous Ovarian Cancer Population, 2004-2019.

(1) Background: The primary objective of this study was to examine the rate of genetic referral, BRCA testing, and BRCA positivity amongst all patients with high-grade serous ovarian cancers (HGSOC) from 2004-2019. The secondary objective was to analyze secondary factors that may affect the rates of referral and testing. (2) Methods: This population-based cohort study included all women diagnosed with HGSOC using the Manitoba Cancer Registry, CervixCheck registry, Medical Claims database at Manitoba Health, the Hospital Discharge abstract, the Population Registry, and Winnipeg Regional Health Authority genetics data. Data were examined for three different time cohorts (2004-2013, 2014-2016; 2017-2019) correlating to practice pattern changes. (3) Results: A total of 944 patients were diagnosed with HGSOC. The rate of genetic referrals changed over the three timeframes (20.0% → 56.7% → 36.6%) and rate of genetic testing increased over the entire timeframe. Factors found to increase rates of referral and testing included age, histology, history of oral contraceptive use, and family history of ovarian cancer. Prior health care utilization indicators did not affect genetic referral or testing. (4) Conclusion: The rate of genetic referral (2004-2016) and BRCA1/2 testing (2004-2019) for patients with a diagnosis of HGSOC increased over time. A minority of patients received a consultation for genetics counselling, and even fewer received testing for a BRCA1/2. Without a genetic result, it is difficult for clinicians to inform treatment decisions. Additional efforts are needed to increase genetics consultation and testing for Manitoban patients with HGSOC. Effects of routine tumour testing on rates of genetic referral will have to be examined in future studies.

The Role of Palliative Medicine in Assessing Hereditary Cancer Risk.

BACKGROUND:: Hereditary cancer assessment and communication about family history risks can be critical for surviving relatives. Palliative care (PC) is often the last set of providers before death. METHODS:: We replicated a prior study of the prevalence of hereditary cancer risk among patients with cancer receiving PC consultations, assessed the history in the electronic medical record (EMR), and explored patients' attitudes toward discussions about family history. This study was conducted at an academic urban hospital between June 2016 and March 2017. RESULTS:: The average age of the 75 adult patients with cancer was 60 years, 49 (55%) male and 49 (65%) white. A total of 19 (25%) patients had no clear documentation of family history in the EMR, sometimes because no family history was included in the admission template or an automatically imported template lacked content. In all, 24 (32%) patients had high-risk pedigrees that merited referral to genetic services. And, 48 (64%) patients thought that PC was an appropriate venue to discuss the implications of family history. The mean comfort level in addressing these questions was high. CONCLUSIONS:: At an academic center, 25% of patients had no family history documented in the EMR. And, 32% of pedigrees warranted referral to genetic services, which was rarely documented. There is substantial room for quality improvement for oncologists and PC specialists-often the last set of providers-to address family cancer risk before death and to increase use and ease of documenting family history in the EMR. Addressing cancer family history could enhance prevention, especially among high-risk families.
