Publication month/year

Study question
To investigate the addition of bevacizumab to standard chemotherapy in the first-line treatment of ovarian cancer
Type of study
Clinical trial
Interventions compared
Standard-chemotherapy group (carboplatin and paclitaxel) Vs Standard Chemotherapy & bevacizumab group
Experimental arm (Intervention)
Bevacizumab group (standard chemotherapy plus bevacizumab (7.5 mg per kilogram of body weight), given concurrently every 3 weeks for 5 or 6 cycles and continued for 12 additional cycles or until progression of disease)
Control arm
Standard Chemotherapy consisting of carboplatin (area under the curve, 5 or 6) and paclitaxel (175 mg per square meter of body-surface area), given every 3 weeks for 6 cycles
Primary outcome
- progression-free survival
- overall survival
Secondary outcome
- biologic progression-free interval
- response to therapy
- toxicity
- and quality of life.
Inclusion criteria
- After undergoing surgery
- Histologically confirmed, high-risk, early-stage disease (International Federation of Gynecology and Obstetrics [FIGO] stage I or IIA and clear-call or grade 3 tumors) or advanced (FIGO stage IIB to IV) epithelial ovarian cancer, primary peritoneal cancer, or fallopian-tube cancer (based on local histopathological findings). Additional eligibility criteria were an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
- adequate coagulation values and bone marrow, liver, and renal function, with no plans for further surgery before disease progression.

Notes on the table
hazard ratio for progression or death with bevacizumab added, 0.81; 95% confidence interval, 0.70 to 0.94; P=0.004 by the log-rank test.
Conclusions
Bevacizumab improved progression-free survival in women with ovarian cancer. The benefits with respect to both progression-free and overall survival were greater among those at high risk for disease progression.
