OBJECTIVES/GOALS: The goal of this study is to leverage a national database to see if autologous reconstruction rates differ in patient and clinical characteristics, readmission rates, and overall survival (OS) compared to other forms of reconstruction. Autologous reconstruction has not been looked at in this way before. METHODS/STUDY POPULATION: • Aim 1: Use the National Cancer Data Base to construct three patient cohorts for women under 70 and above 18 treated surgically for breast cancer with A) mastectomy only, B) implant-based reconstruction, and C) autologous breast reconstruction. • Aim 2: Examine receipt rates of surgical intervention in Cohorts A vs. B vs. C based on clinical and patient demographic/socioeconomic characteristics. • Aim 3: Compare readmission and overall survival (OS) rates for Cohorts A vs. B vs. C while controlling for age and other key variables. RESULTS/ANTICIPATED RESULTS: Based on the literature, we expect rates of autologous reconstruction (Cohort C) to be lower for patients of minority backgrounds compared to white individuals. In addition, we do not expect overall survival to differ between implant-based (Cohort B) and Cohort C reconstruction. Still, we expect mastectomy-only (Cohort A) survival to vary from the two cohorts even when adjusting for different clinical factors, as similar but smaller studies have shown. Finally, we expect readmission rates to be higher for Cohort C, compared to Cohorts A & B, as it is a more complicated procedure typically done in academic institutions with skilled surgeons. DISCUSSION/SIGNIFICANCE: Autologous reconstruction is now considered the gold standard due to its ability to restore the breast shape with higher patient satisfaction and superior long-term outcomes. Multiple studies have documented ongoing racial disparities in post-mastectomy breast reconstruction and autologous reconstruction, with lower rates and referrals. |
