Abstract

Purpose of investigation: Randomized trials have demonstrated improvements in overall survival when using platinum doublets compared to single agent platinum in the treatment of women with advanced or recurrent cervical cancer. The authors sought to evaluate the cost effectiveness of these regimens. Methods: A decision model was developed based on Gynecologic Oncology Group (GOG) protocols 179 and 204. Cisplatin alone was compared to cisplatin/paclitaxel (CP), cisplatin/topotecan (CT), cisplatin/gemcitabine (GC), cisplatin/ vinorelbine (CV), and a hypothetical novel agent. Parameters included overall survival (OS), cost, and complications. One way sensitivity analyses were performed. In further sensitivity analysis, a hypothetical agent that added 3.7 months survival to CP's survival was studied. Results: The chemotherapy drug costs for six cycles of cisplatin was 89 USD while for cisplatin/ paclitaxel it was 489 USD. The highest chemotherapy cost was for GC at 18,306 USD. The average total cost of six cycles CP was 13,250 USD while the average cost of cisplatin alone was 14,573 USD. The highest average cost for six cycles was for GC at 33,559 USD. With cisplatin/paclitaxel being the most effective, the cost effectiveness analysis showed that cisplatin, CT, GC, and VC were all dominated by CP. Because of the regimens being dominated, no baseline ICERs compared to CP were calculable. Sensitivity analyses demonstrate that even all of the chemotherapies were given for free, CP would still be the regimen of choice. Conclusions: In this model, CP is the most cost effective regimen for the treatment of these patients with an average cost of 13,250 USD. With the fact that GOG 204 also showed statistically significantly improved survival for CP, CP should be considered the regimen of choice.
