Abstract P4-11-41: Pretreatment neutrophil/lymphocyte ratio and overall survival in African American and white breast cancer patients

Previous studies have shown that the pretreatment neutrophil/lymphocyte ratio (NLR) is an independent predictor of mortality in breast cancer patients. Our aim was to further study the relationship between pretreatment NLR and overall survival in African American and white breast cancer patients treated at an academic cancer center. Electronic medical records were reviewed for 589 patients treated between 2002 and 2011, and pretreatment NLR data, determined at an average of 12 days prior to the initiation of cancer treatment, were available from 217 African American and 218 white patients. Other clinical and patient data were obtained from the hospital tumor registry, with annual follow-up for vital status. There were a total of 102 deaths over a mean follow-up of 59 months. For data analysis, patients were divided into quartiles based on their NLR (Q1: Citation Format: Joseph C Rimando, Jeff Campbell, Jae Hee Kim, Sangmi Kim.
