Influence of Ethnicity on Survival of Breast Cancer Patients in Turkey

Abstract

Background: Kurdish women with breast cancer have more unfavorable prognostic factors than their Turkish and Arab counterparts. However, the effects of these factors on breast cancer survival among these ethnic groups remain unclear. We therefore investigated the impact of ethnicity on survival in breast cancer patients in Turkey. Materials and Methods: Ethnicity, age, stage at diagnosis, tumor characteristics, treatments given (surgery, chemotherapy, radiotherapy and hormone therapy), and survival times were recorded. KaplanMeier analysis was used to estimate the overall survival times and survival plots. Log-rank test was used to compare the survival curves.
