Imaging in breast cancer follow-up: preliminary investigation on clinical practice adherence to the guidelines

PURPOSE: The aim of this study was to assess compliance with guidelines recommendations in the follow-up of patients with breast cancer. In this setting of patients we analyzed the appropriateness of the imaging exams recommended by different specialists in the management of follow-up. MATERIALS AND METHODS: From January 2019 to December 2019 we analyzed the clinical data and the results of the imaging exams of 146 asymptomatic patients followed for follow-up in different regional radiotherapy centers. A logistic regression analysis was performed taking into account the advanced pathological stage, the absence of surgical staging of the lymph nodes, the dubious results from previous basic imaging tests, correlating them to the excessive use of advanced imaging. The association was expressed in terms of odds ratio (OR) together with their 95% confidence intervals (CI). RESULTS: For 96% of patients, a frequent prescription of at least one basic imaging exam (complete abdomen ETG and chest X-ray 2p) was observed in contrast to the guidelines. A finding of a large number of bone scans suggested their use as routine surveillance A positive correlation with advanced imaging (OR <1) was seen in patients with borderline basic imaging. CONCLUSIONS: Follow-up with intensive imaging is poorly effective both for the early diagnosis of relapses and for any remote localizations.
