Introduction/Background The aim of this study is to examine the effects of obesity on patient characteristics and other accompanying factors, as well as on mean and disease-free survival in patients diagnosed with ephitelial ovarian cancer.

Methodology The files of 1053 patients who were diagnosed with ephitelial ovarian cancer in our hospital between 1992 and 2018 in the Department of Obstetrics and Gynecology of Çukurova University Balcalı Hospital were retrospectively analyzed. Among these patients, 939 patients whose anthropometric data could be accesed were included in the study. The body mass index (BMI) calculations of the patients included in the study were made and they were categorized according to the obesity classification of the World Health Organization. Then, patients‘ characteristics and survival were compared accordingly.

Results It was determined that mean survival rates of the weak, obese, and morbidly obese patients were lower than normal weight patients (p=0,001). There was no significant difference between BMI groups in terms of disease-free survival.

Conclusion Comorbidities brought about by obesity may have negative effects on the average survival of ovarian cancer
