OBJECTIVES/GOALS: Due to clinical advances, cancer survivors are living longer but have an increased risk of a second primary cancer (SPC). This cross-sectional study aims to examine SPC prevalence in immigrant women and compare healthcare use (HCU) and cancer screening in immigrants with SPC versus (1) immigrants with a single cancer and (2) US-born women with SPC. METHODS/STUDY POPULATION: The study population will include adult women with breast/gynecologic primary cancer (PC) from the 2005, 2008, 2010, 2013, and 2015 National Health Interview Survey. First-generation immigrant or US-born status will be defined by region of birth. SPC includes diagnosis with a second cancer type ≥1 year after the initial PC diagnosis. We will compare the prevalence of ≥1 SPC in immigrant and US-born women. To evaluate HCU and cancer screening differences, we will assess sociodemographic and socioeconomic factors, risk behaviors, length of US residence, and citizenship status with descriptive statistics. In regression analyses, we will compare number of provider visits and cancer screening rates in immigrant women with SPC versus immigrants with PC alone and US-born women with SPC after matching by age and PC type. RESULTS/ANTICIPATED RESULTS: Disparities in cancer diagnosis, quality of care, receipt of recommended treatment, and screening rates among immigrants in the US are well documented. Therefore, we hypothesize that immigrant cancer survivors will have similar or higher rates of SPC compared to women born in the US with variations based on health status. We further hypothesize that immigrants with SPC will report lower rates of HCU after diagnosis of their first cancer and cancer screening compared to US-born women. However, we expect that immigrants with SPC will report similar or higher rates of HCU and cancer screening compared to immigrant women with PC alone. DISCUSSION/SIGNIFICANCE: To our knowledge, this study will be the first to describe SPC among immigrant cancer survivors in the US. This research will inform interventions to improve cancer care delivery and ultimately reduce SPC in immigrants with cancer.
