RESUMO
INTRODUCTION: The objective of this study was to estimate the theoretical needs -based on evidence- of radiotherapy treatments (RDT) in Andalusia, compare these needs with actual use of RDT in 2006 and analyse their evolution from 2003. MATERIALS AND METHODS: Correlation between quantitative variables was analysed with Pearson's correlation coefficient. This dealt with differences between administered/estimated treatments and treatments carried out in years with the Student's t-distribution, and the Xi2 test among qualitative variables. RESULTS: In Andalusia, the evidence-based rate of cancer irradiation is 55%. Eighty-five percent of theoretical treatments were administered in 2006. From this group, 107% were in gynaecological tumours, 100% in breast cancer cases, 71% in head and neck cancer and 48% in lung cancers; differences in the last two conditions were significant (p<0.01). As for regional distribution, differences were reported with reference to irradiation rates (p<0.0002) and resource distribution. In the last three years, an increment of 17% was observed in treatments conducted in public hospitals. The rate increased from 61% (with regard to optimal values) to 85% in 2006; in a parallel way, an increment was seen in therapy units (from 22 to 26) and radiation oncologists (from 57 to 69). CONCLUSIONS: Despite the increment of irradiation rates seen in the last years, there is still a serious underutilisation of RDT for some cancer types (lung, head and neck cancer), as well as a great variability in the use of RDT between hospitals.
