Abstract only e12574 Background: Currently there are no primary cultures or cell lines derived from patients with breast cancer and obesity. It has been postulated that breast cancer in obese women behaves differently as it does in non-obese women, as is composed of distinct biological features, as was generated in a different metabolic environment, as well as pertains to a different prognosis and different response to chemotherapy, lower rates of overall survival and a greater probability of recurrence. By creating a primary breast cancer culture bank of breast cancer tumors from women with obesity (BMI > 30kg/m 2 ), we will establish a cell line exclusive to obese women in Mexico, where targeted therapy may be tested and treatment may be individualized depending on the characteristics of the patient. Methods: This study recruited 32 women with breast cancer and a BMI > 30 kg/m 2 , matched by 6 controls with are non-obese women with breast cancer. Elegibility criteria was determined by women with breast cancer confirmed by pathology, who had not been subjected to prior treatment regarding the neoplasm. The breast cancer removing surgeries and the patients were selected from the ABC Medical Center in Mexico City and all procedures were approved by the research and ethics committee of the hospital in question. Results: Through extensive communication a cooperative protocol was established between the departments of surgery, oncology, pathology and nursing to coordinate efforts and be able to take a 2 – 5 mm sample of the breast tumor removed from the patient. To be able to distinguish cancer cells from non-cancer cells (epithelial cells, fibroblasts, adipocytes) the Hayflick limit was be utilized. Once a primary breast cancer culture was established, 12 million cells will be injected into the subscapular area of athymic, nu-nu mice to be able to monitor tumoral growth in vivo and conduct a subsequent cellular analysis, determining it still pertains to the same characteristics of the tumor from which it was obtained. Conclusions: A primary breast cancer culture repository from patients with a BMI > 30 kg/m2 was established. This is the first primary breast cancer culture for both Mexican and obese women with breast cancer, the first in vitro method of analysis of specific characteristics typical of the Mexican population. Translational research may now be conducted on these new tumoral cultures to create individualized therapy for women with the distinct, aforementioned characteristics.
