Newer forms ofadjuvant chemotherapy can considerably improve the prognosis for breast cancer. The benefits that can be achieved are particularly high for young women (< 50 years) with an unfavourable risk profile (tumour-positive axilliary nodes). The recent application of taxans and trastuzumab has sharply increased the costs of an adjuvant treatment for high-risk mammary breast carcinoma. The cost increase can especially be attributed to trastuzumab. The additional costs of cytostatics (10,079 Euro per life-year gained) appear to be justified if the following is taken into account: women under the age of 50 years still have a life expectancy of approximately 33 years, many have socially relevant positions, and that cure also prevents such things as absence through illness and inability to work as well as expensive palliative care. The pharmaceutical industry spends approximately the same amount on research and innovation as it does on advertising. By reducing marketing costs, there will be more room to lessen the costs of new and socially relevant medications. Ultimately, the pressing question remains on why the Dutch government does not fully compensate hospitals in the Netherlands for the introduction of new, potentially life-saving medications. At present, a substantial percentage of the costs has to be paid by the hospitals themselves out of the regular hospital budget, which is not meant for this. This is happening at the expense of other care to an increasing extent.
