CRA1505 Background: The cancer family history (CFH) is an important tool for identification of individuals for genetic counseling/testing (GC/GT). Prior studies demonstrate a low rate of family history documentation and low referral rates for genetic counseling and genetic testing. Methods: In 2011ASCO began pilot testing new measures in QOPI to evaluate the practice of family history taking and referral for genetic counseling/testing in patients with either breast cancer (BC) or colorectal cancer (CRC). The measures assessed the presence or absence of CFH in 1st/2nd degree relatives, age at cancer diagnosis, referral for GC/GT and outcomes of referral. Results: Between September and October 2011 272 practices pilot tested these measures and reported on 10,466 patients (BC 6569, CRC 3897). 77.4% of all charts reviewed documented presence or absence of CFH in 1st degree relatives (BC 81.2% (CI 80-82%), CRC 77.4% (CI 76-79%), p= <0.001) and 61.5% of charts documented presence or absence of CFH in 2nd degree relatives (BC 68.9% (CI 68-70%), CRC 57.3% (CI 56-59%) p=<0.001). Age at diagnosis was documented for all relatives with cancer in 30.7% of charts (BC 45.2% (CI 44-47%), CRC 35.4% (CI 34-37%) p=<0.001). Patients were referred for GC/GT in 22.1% of all charts reviewed (BC 29.1% (CI 28-30%), CRC 19.6% (CI, 18-21%) p=<0.001). Of patients with hereditary risk (defined by selected risk guidelines) 52.2% of BC and 26.4% CRC were referred for GC/GT. When genetic testing was performed by the practice consent was documented 77.7% of the time and discussion of results was documented 78.8% of the time. Conclusions: Appropriate referral for GC/GT requires a complete and accurate CFH. In this pilot testing of QOPI measures we identified a higher quality of CFH information than expected though with room for improvement. Significant differences were seen between BC and CRC charts with greater accuracy of CFH and higher referral rates among BC patients. To obtain improvement in the identification and management of patients at high risk, significant improvements are needed. Education is part of the answer.
10554 Background: Uptake of chemoprevention and prophylactic surgery among women at high risk for breast cancer is low, despite proven efficacy. We evaluated breast cancer risk factors as predictors of uptake of prevention treatment (PT) to better understand potential associations with these decisions. Methods: An IRB approved registry established in 2003 at the University of Vermont of high-risk women was used to evaluate the association between both modifiable (obesity, sedentary lifestyle and alcohol use) and non-modifiable (age, history of benign breast disease [BDD], genetic predisposition) risk factors and uptake of PT. Women were eligible for inclusion in this analysis if they had one of the following risk factors (BDD, strong family history, > 20% lifetime modeled risk or genetic predisposition) and completed questionnaires regarding diet and physical activity. Alcohol use was assessed using a health questionnaire and physical activity was assessed using a 7-Day Physical Activity Recall questionnaire. We used logistic regression to estimate odds ratios (OR). Results: 504 women were included and had been followed for median of 13 years. Mean age was 44.5 years (range 19 – 75), 98% were Caucasian, and mean BMI was 26.9 (range 17-57). 78% had a family history of breast cancer, 60% had >20% lifetime modeled risk, 14% had a history of benign breast disease (BBD), and 9% of women had confirmed genetic risk in high or moderate risk genes. Women may have had more than one risk factor. 55% were physically active and 55%. 4.2% were sedentary and 12.3% consumed > 1 alcoholic beverage daily. 20.8% of the cohort participated in PT (8.1% took chemoprevention, 2.0% underwent prophylactic bilateral total mastectomy and 10.7% underwent risk reducing salpingo-oophorectomy). Among non-modifiable risk factors, age, genetic predisposition (ORadj 8.66, 95% CI 2.30–32.33, p < 0.0001), and history of benign breast disease (ORadj 4.09, 95% CI 1.89–8.86, p < 0.001) were associated with uptake of PT. Increasing age was associated with increasing uptake (ptrend was > 0.0001) and highest among women aged 60-69 years (ORadj8.19, 95% CI 2.87-23.37 relative to women aged < 40). Women with a strong family history were significantly less likely to take up PT (p = 0.04). BMI, physical activity status and alcohol use were not associated with uptake of PT. Conclusions: Like other studies, we found a low uptake of PT among women at high risk for developing breast cancer. We found that modifiable risk factors were not associated with uptake of PT, which might suggest that high-risk women with modifiable risk factors could be targeted for interventions designed to modify risk (i.e. chemoprevention, weight reduction, etc). Interestingly, women with a strong family history may be less likely to take up PT, and studies to further examine this relationship may identify opportunities for interventions to improve uptake.
