Comparative analysis of cost of drug therapy of the most high-cost oncological diseases in Moscow

Objectives. According to literature and experts, prostate cancer (PC), breast cancer (BC), colon cancer (CC), melanoma (MEL) and renal cell carcinoma (RCC) are the most high-cost oncological diseases. The aim of our study was to calculate the charges for each of these nosologies from the point of view of Moscow’s budget and compare them with each other. Methods. To assess the annual costs of drug therapy in Moscow in patients with PC, BC, CC, MEL and RCC there has been developed an analytical model in MS Excel software, considering the data of Cancer Register, as well as literature sources. Results. There has been estimated that if the costs of drug therapy for all five of assessed types of cancer are taken as 100 %, then the most costly is BC (41 % of costs), then MEL (20 %), RCC (15 %), CC (13 %) and PC (12 %). There has been also calculated, that if the number of patients with all five types of assessed cancer undergoing drug therapy, we would consider as 100 %, the highest percentage of them is in BC (50 % of all patients), then PC (36 %), CC (9 %), MEL (3 %) and RCC (1 %). Conclusions. The structure of drug therapy costs in patients with PC, BC, MEL, CC and RCC in Moscow shows that the most expensive is the treatment of patients with melanoma (for 3 % of patients Moscow City Health Department spends 20 % of charges) and RCC (1 % of patients spends 15 % of charges).
