Aim of paper: Retrospective pharmacoeconomic cost-effectiveness analysis of treatment of patients with FIGO stage III-IV ovarian cancer using two protocols: cisplatin + paclitaxel (PT) or cisplatin + cyclophosphamide (PC). Material and methods: Analysis was based on medical records of 80 patients treated at the Center of Oncology in Bydgoszcz. The main criterion of therapeutic response was survival time over a 5-years’ follow-up period. Analyzed direct medical costs included: hospitalization, ambulatory treatment, diagnostic tests, drugs, radiotherapy, medical consultations and treatment of hematologic complications. The study focused on the following: pharmacoeconomic analysis of cost-effectiveness, incremental cost-effectiveness ratio and sensitivity analysis. Results: Cost of hospitalization was the major component of total cost of both treatment protocols (PT – 58% , PC – 56%). In the one-day setting, share of hospital costs was also similar in both cases (PT – 13.30%, PC – 13.49). Share of costs of pharmacotherapy and radiotherapy was 17.62% (PC) and 18.97% (PT). The least expensive were medical consultations and treatment of hematologic complications. The PT protocol was more effective but also more expensive, with mean total cost of treatment per patient 19 620.30 PLN and mean survival time 27.6 months. Mean cost of treatment per patient by the PC protocol was 18 700.26 PLN and mean survival time – 25.9 months. Incremental analysis revealed that additional cost of one month of survival (incremental coefficient of cost-effectiveness) when replacing protocol PC by PT is 541.20 PLN per patient. Conclusions: From the pharmacoeconomic point of view, use of the PT protocol in the treatment of advanced ovarian cancer is justified.
