PURPOSE: Regular physical activity is associated with fewer exacerbations, hospitalizations and improved survival in patients with COPD. However, patients encounter a number of barriers to starting and sustaining a regular exercise program. The purpose of this abstract is to describe patients' barriers as they commence a physical activity program as part of a large clinical trial.
Background: Recruiting participants who are representative of the population as a whole is essential to ensure the development of treatments that benefit all rather than a select few. Understanding the reasons patients accept or decline participation, and then making adjustments to the recruiting process based on these findings, is one way to encourage study participation. Aim: To better understand what factors influence a potential participant's decision to either accept or decline participation in breast cancer trials. Methods: These are preliminary data from a pilot study that uses a short questionnaire to investigate which factors influence a woman's consent or decline to study participation. Women are approached for this study after being asked to participate in one of three other breast cancer trials targeting women who either have breast cancer or are at high risk for breast cancer. Women are approached for this study regardless of their decision to participate in the previous study. Participants are asked a set of questions about 1. the specific interaction they had with the consenter from the previous study, 2. general characteristics of a consenter, and 3. research in general. Demographic information is also collected for future analysis of responses based on race/ethnicity, income, education level, and primary language. Results: A total of 24 participants have completed the questionnaire so far, with an accrual rate of approximately 25 patients per month. Participants ranked the importance of the various factors on a 4-point scale with 1 being “not important at all” and 4 being “very important.” Factors that participants indicated were the least important to their decision to participate were: financial compensation (xÌ… 1.07), racial/ethnic parity between consenter and consentee (\bar x $ 1.19), consenter looking like someone from their community (\bar x $ 1.19), gender parity (\bar x $ 1.19), religious beliefs (\bar x $ 1.38), pleasing their doctor (\bar x $ 1.56), and feeling overwhelmed (\bar x $ 1.85). Factors participants indicated were the most important to them were: the desire to benefit others in the future (\bar x $ 3.63), to benefit their family (\bar x $ 3.56), to acknowledge the contributions of past generations (\bar x $ 3.20), the feeling participation was “the right thing to do” (\bar x $ 3.15), presence or lack of potential side effects associated with participation ((\bar x $ 3.15), feeling empowered by the consenter (\bar x $ 3.15), feeling the consenter was listening (\bar x $ 3.11), and trust in research (\bar x $ 3.07). Conclusions: Concerning the consenter, physical characteristics such as race/ethnicity and gender parity were less important than the actual interaction with the consenter, including their flexibility, listening skills, and ability to make the patient feel empowered. For research in general, the idea of contributing to the “greater good” emerged as a powerful motivation to participate. An emphasis on this, as well as well-trained consenters, may help studies attract more participants. Note: This abstract was not presented at the conference.

Despite cancer being the leading cause of death across most racial/ethnic groups, Hispanic women have the second highest mortality rate attributed to diabetes (4.7%) according to the Centers for Disease Control and Prevention (CDC). While cancer and diabetes are two distinct diseases, previous studies have demonstrated that diabetic women have a poor chance of breast cancer survival when compared to nondiabetic women. Well-known key drivers of hyperinsulinemia and insulin resistance, such as insulin and AMPK, are also those involved in breast cancer. This link could possibly contribute to the increased mitogenic effects and risk for aggressive breast cancers in Hispanic women. Based on these findings, metformin, a drug standardly used to treat and prevent hyperglycemia, may be a possible alternative (other than tamoxifen) for breast cancer prevention. Eat, Move, Live (EML), a 5-week community-based program, focuses on targeting possible treatments of chronic diseases and risk reduction through attitude and lifestyle modifications. Exercise, nutritional and health awareness classes were implemented to change participants' perspectives regarding chronic diseases and their susceptibility to other morbidities. Questionnaires were given to the participants at baseline and at two follow-ups (5 weeks and 12 weeks) to assess any changes in their attitudes, behaviors, nutrition, lifestyle and beliefs around taking medication for preventative treatments. A total of 56 participants' pretreatment responses were collected via a five-point Likert scale (1-strongly disagree, 5-strongly agree). Demographic data showed that 69% of the respondents were Hispanic women, of whom 46% completed an education level of high school or less. A majority of the responses averaged a “neutral” response to taking medication for management and prevention of diabetes. We infer that their inability to select a stance in their responses may be associated with the lack of knowledge that the community has regarding chronic diseases and risk-prevention methods. Therefore, we anticipate that availability of proper education tools and resources is essential to potentially prevent future morbidities and mortalities. Ultimately, we aim to establish a pilot study that emphasizes the necessity and importance of interventional programs, like EML, to enhance chemoprevention using metformin and improve health outcomes in high-risk breast cancer populations.

Purpose: To highlight the importance of building a high-risk breast cancer clinic for women who do not have a BRCA 1, BRCA 2 or other highly penetrant cancer susceptibility mutation. Background: Breast cancer is the most common cancer in women and the second most prevalent cause of cancer death of women in the United States; the lifetime risk for breast cancer in women is approximately 12%. Women may be at increased risk for breast cancer for many reasons including family history, genetic alterations, age, reproductive status and menstrual history. Most women who are at increased risk of developing breast cancer do not have a BRCA 1, BRCA 2 or other mutation. The majority of breast cancer diagnoses are due to acquired somatic mutations; only 5 to 10% of breast cancer diagnoses are attributable to highly penetrant Mendelian cancer susceptibility genes. White women with Ashkenazi Jewish ancestry tend to have a higher incidence of BRCA 1 and 2 mutations; traditionally, most research efforts about highly penetrant genes have been focused on this group rather than other racial and ethnic groups. However, there is a great need to study breast cancer risk-reduction strategies in racial and ethnic minorities in the United States, particularly because most breast cancers are not caused by BRCA 1 and 2 mutations. City of Hope is located approximately 21 miles northeast of Los Angeles and operates 13 clinical practice locations including Los Angeles, Orange, Riverside, San Bernardino and Ventura counties. These five counties are home to the majority of California's multicultural and ethnic residents where San Bernardino County has the highest percentage of Hispanics (49.9%) and blacks (8.3%), Ventura County has the highest percentage of whites (48.1%), and Orange County has the highest concentration of Asians (18.2%). It has been established in the literature that the greatest benefit from breast cancer prevention strategies comes from treating women who are at high risk of the disease. While it is important to build a high-risk breast cancer clinic for women with genetic mutations, it is equally important to build a high-risk breast clinic for women who are at increased risk of breast cancer but do not have a mutation, particularly because most breast cancer is diagnosed in this population. In addition, it is crucial to educate high-risk patients that although they may have tested negative for a genetic mutation if they have a family history of breast cancer, they warrant close clinical surveillance. Methods: We are proposing a retrospective, descriptive study of data that will be collected as part of a high-risk breast cancer program implemented by City of Hope. Results/Conclusions: We expect to discuss the findings related to serving women of all races and ethnicities who do not have a mutation in a highly penetrant gene mutation.
