e18544 Background: Cultural barriers that inhibit LGBTQ cancer care are a public health crisis. Although LGBTQ cultural competency trainings are rapidly becoming the norm, patient-centered information is lacking for healthcare professionals in cancer care. The purpose of OUT: The National Cancer Survey is to understand the experiences of LGBTQ cancer survivors in order to make cancer care a safer and more welcoming place for survivors and their support teams. Methods: Individuals age 18 or older currently living in the United States who have been previously diagnosed with cancer and who identify as LGBTQ+ were recruited via community partnerships and targeted paid social media advertisements with an oversample of media outreach to Black Indigenous and People of Color (BIPOC). Participants completed a cross-sectional web-based survey of their cancer care experiences. This resulted in a final sample of [1,600+] survivors, the largest known sample of LGBTQ+ cancer survivors in the world. The sample was weighted to adjust for U.S. sex assigned at birth and racial/ethnic demographics. Descriptive statistics were used to summarize participant responses, crosstabs were used to compare responses across demographic categories, and excerpted responses are used to highlight qualitative themes. Results: Participants ranged in age from X to X years (median X). X% of the sample identified as either gay or lesbian, X% as bi, and X% as trans or gender nonconforming. X% of the sample identified as White only, followed by X% as Latine, X% as Black and X% as other or mixed race. Most common cancer types included XYZ. When asked about welcoming care, X% of the sample reported they specifically sought an LGBTQ+ welcoming provider after diagnosis. Most common methods for finding such a provider included: X, X, and X. Most common cues that helped patients identify welcoming providers included X, X, and X. Overall X% reported receiving care in an LGBTQ+ welcoming environment but X% did not. Of those who did not receive care in a welcoming environment, they were more likely to be X, X, and X. Overall, X% of patients were out to their providers, but this varied by X, X, and X. The most common ways of coming out included X, X, and X. When asked what they wanted to tell health care providers to ensure better care, participants highlighted several themes, including: X, X, and X. These findings provide patient driven insights into how cancer care varies within the LGBTQ+ population by different demographic factors and specific strategies providers can take to enhance care for LGBTQ+ people.
