  1. Radiation therapy : are we getting value for money ?

    Article - En anglais

    The aim of this study was to examine the long term cost effectiveness of radiotherapy (RT) in the treatment of cancer at the Department of Radiation Oncology, Westmead Hospital, from its inception in 1980 to December 1993.

    A Kaplan-Meier survival curve was constructed for all patients treated by RT during the study period.

    The area under this curve represented the average survival.

    The total number of life years was calculated by multiplying the number of patients by the average survival.

    Costing for one RT treatment field had previously been derived.

    The cost included capital costs, building costs and overheads as well as labour, goods and services, and operating costs.

    The cost per field was multiplied by the total number of fields given each year and the yearly total summed to give the total cost.

    The total cost was divided by the number of life years to give a cost per life year.

    An overall percentage survival gain was estimated from departmental results and the literature.

    Cost per life year gained (LYG) was derived by dividing the cost per life year by the percentage survival gain.

    Sensitivity analysis was performed with best-and worst-case survival scenarios, and high and low cost per field estimates.

    A total of 9868 patients were treated by radiotherapy between January 1980 and December 1993.

    Median follow-up was 4.2 years.

    Median survival was 2 years.

    The 5-and 10-year survival rates were 35% and 22%, respectively.
