Clinical outcomes of obese low socioeconomic status women diagnosed with invasive breast cancer.

Abstract #6092 Background: Obesity a possible risk factor for breast cancer development, may along with low socioeconomic status (LSES) influence breast cancer outcomes. Louisiana a state with the second highest level of poverty has an obesity prevalence above 25%. The Feist-Weiller Cancer Center (FWCC) provides oncology care to the majority of LSES patients (pts) in the nothern half of the state. This study examines if there is a difference in clinical outcomes in obese patients with invasive breast cancer treated at FWCC.
 Methods: The electronic medical records of pts with histologically proven invasive breast cancer diagnosed between 1981-2006 at FWCC were reviewed. Pts with Stage IV breast cancer at diagnosis were excluded. Data on insurance, race, body mass index at diagnosis (BMI), stage, disease free interval (DFI) and survival time was analyzed. National Institutes of Health criteria was used to stratify pts into normal weight (NW)[ BMI 2 ], overweight (OW) [BMI 25-30 kg/m 2 ], and obese (OB)[BMI >30 kg/m 2 ]. LSES was defined as pts who were either uninsured or received Medicaid assistance. Differences in DFI and Overall survival (OS) were analyzed by BMI.
 Results: 647 pts were analyzed, 49% were obese and 29% were overweight. 47% were African Americans and 53% were Caucasians. 49% had LSES (22% uninsured and 27% received Medicaid). Obese pts were more likely to be African American (58%; p Citation Information: Cancer Res 2009;69(2 Suppl):Abstract nr 6092.
