paragraph: Therapeutic effect of bevacizumab combined with paclitaxel and carboplatin on recurrent ovarian cancer. To observe the clinical efficacy and safety of bevacizumab (BEV) combined with paclitaxel on recurrent ovarian cancer. ### methods A total of 164 patients with recurrent ovarian cancer were selected and randomly divided into two groups : experimental group ( n=82 , BEV + paclitaxel + carboplatin ) and control group ( n=82 , paclitaxel + carboplatin ) . The clinical therapeutic effects including objective response rate (ORR), complete response (CR) rate, partial response (PR) rate, stable disease (SD), progressive disease (PD), progression free survival (PFS) and overall survival (OS) were evaluated, together with the adverse clinical reactions and improvement of quality of life (QoL). Immunohistochemistry was used to detect the expression of phosphate and tension homology deleted on chromosome ten (PTEN). ### results The PFS, OS and ORR of patients in the experimental group were significantly higher than those in the control group (p<0.05). In addition, the incidence rates of allergy, gastrointestinal reactions and leukopenia were significantly lower in the experimental group compared with those in the control group (p<0.05). There was no significant difference in QoL score between the two groups before treatment (p>0.05). However, after treatment, the QoL score in the experimental group was increased significantly compared with the control group (p<0.05). Moreover, the expression of PTEN in PR, SD and PD patients was lower, with significant difference between the two groups (p<0.05). ### conclusion The clinical therapeutic effect of BEV combined with paclitaxel in patients with recurrent ovarian cancer was improved, suggesting it might be beneficial for the treatment of ovarian cancer.
