We sought to evaluate the cost effectiveness of some newer combination therapies in cervical cancer. Patients and methods: A cost effectiveness decision model was used to analyze Gynecologic Oncology Group 240. All regimens were modeled for seven cycles. The regimens studied are as follows: regimen 1, cisplatin/paclitaxel (CP); regimen 2, CP with bevacizumab (CP+B); regimen 3, paclitaxel/topotecan (PT); and regimen 4, PT with bevacizumab (PT+B). Overall survival, cost, and complications were studied. Sensitivity analyses were performed. Results: Mean chemotherapy costs over mean total costs for seven cycles of each follows: CP $571/$32,966; CP+B $61,671/$96,842; PT $9,211/$71,620; and PT+B $70,312/$109,211. Incremental cost-effectiveness ratio (ICER) for CP+B was $133,559/quality adjusted life year (QALY). ICER for PT+B was $124,576/QALY. To achieve an incremental ICER for CP+B:CP of <$50,000/QALY gained, the mean overall survival has to increase from 1.1 years with CP to 3.5 years with CP+B. An ICER <$50,000/QALY for the other regimens would take a survival of >10 years for PT and 4.1 years for PT+B. Treating 1,000 women with cervical cancer with CP+B would cost almost double the cost of treating >18,000 women with ovarian cancer annually (carboplatin/paclitaxel). Conclusion: CP is the most cost effective regimen. A 12-month increase in overall survival will not even make the newer combinations cost effective. Currently, the use of bevacizumab is not sustainable at today's costs. Keywords: cervical cancer, chemotherapy, bevacizumab, cost-effectiveness
