The study's objectives were to observe and describe chemotherapy treatment (CT) used in breast cancer (BC) patients in Spain and estimate its cost.
Multi-centre and transversal study, which included consecutive BC patients treated with chemotherapy between 10 and 15 May 2004 in 110 centres throughout Spain. Information was gathered on the general characteristics of the centres, the patient data and the treatments administered. This information was collected prospectively based on the data available in the pharmacy service and/or the patient's clinical history. The following information was requested: demographic, clinical, CT administered during the week of the study, established guidelines, inclusion in clinical trials and the direct costs of the medication.
A total of 2,134 patients were included (99.7% women) from 16 autonomous communities and the average age was 51.5. The majority of the treatments were administered in general hospitals (89.7%), public or public health partnership hospitals (91.5%) and level 3 specialist hospitals (64.5%). Among these patients, 120 (5.6%) received treatment as part of a clinical study. A total of 51% of patients received adjuvant or neoadjuvant treatment, mainly for stage IIA disease (28.7%). A total of 1011 patients presented metastatic disease (MD). The estimated average cost of chemotherapy treatment was euro428.5 per cycle and the group of patients with MD incurred the greatest cost (euro640.4 per cycle).
The results show the current situation of CT for BC in Spain and a great deal of variability is observed both in the use of drugs as well as in the associated costs.
