[The cost of radiotherapy].

The higher human and material costs induced by the development of conformal radiotherapy and other innovative techniques have to be evaluated. Different studies reflect benefit for three-dimensional conformal radiation therapy. This needs appropriate economic analyses (cost/benefit, cost/utility). Conclusions from studies are rather in favour of new technics of radiotherapy when compared to standard technics and alternative therapeutic procedures and justify investments. The two cost accounting available in France are compared. Until now, medical reimbursements underestimate the costs related to treatment, slowing down implementation of new equipment and quality therapeutic practices. The mean reimbursement was 1,670 Euro always under mean real costs. To promote innovative treatments more rational reimbursement modalities are necessary. European experiences demonstrate than modern radiotherapy facilities don't induce expensive costs (average 3,800 Euro).
