Abstract P1-09-06: Imaging Tests in Staging and Surveillance of Early Breast Cancer (EBC) — Changes in Routine Clinical Practice and Cost Implications
2010
Background. New imaging tests such as computed tomography [CT], [18F]fluorodeoxyglucose-positron emission tomography (FDG-PET) scanning and magnetic resonance imaging (MRI) are not recommended for staging or follow up of asymptomatic patients with EBC according to current guidelines. However, frequently these tests are requested even in the absence of a clinical indication. Variations in practice patterns have significant cost implications and no clear impact on cancer outcomes. Aim. In the present study we analyzed how the availability of novel and more expensive imaging technique has changed staging and follow-up modalities in EBC patients and if these changes affect costs. Methods. Two thousand and five patients with EBC diagnosed between January 2005 and December 2008 were identified using clinical computerized medical records from 639 general practitioners assisting 915,689 inhabitants of the Campania, a southern region of Italy. For each year EBC incidence, the mean number of diagnostic tests per patient (N/Pt) done during the first year after the initial diagnosis and the mean costs per each year were evaluated and compared by Anova test. Results. We identified 576, 489, 474 and 497 newly diagnosed cases of EBC in 2005, 2006, 2007 and 2008 respectively. Table 1 Table 1 describes changes in the mean number of different imaging tests requested per patient in these years. Overall, there was a significant increase of the mean number of imaging tests done per patient from 2005 to 2008 (P Conclusions. TC scan, PET scan and MRI employment for patient with EBC in daily clinical practice has been steadily growing over the past four years. However, there are no data to support their role in routine breast cancer staging or surveillance in asymptomatic patients. More studies are needed to characterize which subset of patients deserve more intensive staging and follow up procedures as costs related to these imaging test prescriptions are relevant.
