AB Background/Aim: Chemotherapy-associated toxicity is one of the limiting factors regarding treatment efficacy, patient outcome and quality of life in this collective. Underweight or obese patients represent a major group in which the therapy seems to be more challenging. The aim of this analysis was to evaluate the impact of BMI on the toxicity in patients undergoing chemotherapy. Patients and Methods: The data of three prospective phase II/III studies (‘Tower’, ‘Topotecan phase III’ and ‘Hector’) of the North-Eastern German Society of Gynecological Oncology including 1,213 patients with recurrent ovarian cancer were retrospectively analyzed. The study was performed using logistic regression and Cox regression analysis. Results: The median age at diagnosis was 59 years. Sixty-seven (5.5%) patients had BMI <20 and 272 (22.4%) patients had BMI >30. Preterm termination of the chemotherapy was associated with lower BMI (p=0.017). Moreover, non-hematological toxicity grade III/IV was mainly observed in underweighted women as well (p<0.001). Patients with higher BMI more often presented with grade III/IV anemia (p=0.019) and as a consequence required blood transfusions more frequently (p=0.005). The overweight group was also associated with a higher number of co-medications. However, no difference in survival regarding BMI was observed in our study. Conclusion: Fewer chemotherapy cycles and preterm discontinuation were more frequent in patients with lower BMI. Hematological toxicity and higher medication intake appeared more often in patients with higher BMI.
