Background: We aimed to evaluate the effect of bevacizumab-containing regimens (BCRs) on the survival of children with relapsed or refractory solid tumors. Materials and Methods: Files of children with relapsed or refractory solid tumors treated with BCR were retrospectively reviewed for age, gender, follow-up time, histopathological diagnosis, adverse events observed with BCR, number of chemotherapy protocols used before BCR, the best overall response obtained with BCR, time to progression, number of BCR courses given to patients, the status of patient at last visit, and outcome. Results: Thirty patients (16 boys, 14 girls) were treated with BCR. The median age at diagnosis was 8.5 (2 - 17) years and at the time of the study was 11 (3-21) years. The median follow-up time was 25.7 (5-79.4) months. The median follow-up time after the start of BCR was 3.2 (1-27) months. Histopathological diagnosis was central nervous system tumors in 25, Ewing sarcoma in two, osteosarcoma in two, and rhabdomyosarcoma in one patient. BCR was given as second-line in 21, third-line in six, and fourth-line protocol in three patients. No chemotherapy toxicity was observed in 22 (73.3%) patients. The best overall response was progressive disease in 17 (56.7%), partial response in seven (23.3%), and stable disease in 6 (20%) patients at first-response evaluation. The median time until progression was 77 (12-690) days. During the study period, 17 patients died of progressive disease. Conclusion: Our study revealed that adding antiangiogenic agent bevacizumab to cytotoxic chemotherapy provided no survival benefit in children with relapsed or refractory solid tumors.
