“…The ICDR rate of US in our cohort is 0.38%. This is amongst lowest reported in the range of detection rates in the literature, which ranges from 0.28 to 0.8% [ 11 , 12 , [14] , [15] , [16] , [22] , [23] , [24] , [25] , [26] ]. The lower ICDR in this cohort owes to the design of the study and methods of US screening.…”

Purpose To determine the diagnostic parameters of breast ultrasound (US) in the setting of routine radiological surveillance after a diagnosis of breast cancer and evaluate costs of the inclusion of breast US as well as any survival benefit of US detected cases of recurrence in surveillance. Methods 622 patients underwent breast cancer surgery and follow up at Austin Health from July 2009 to December 2015. Retrospective data analysis was performed to determine; diagnostic parameters, financial costs of US and survival outcomes of US detected cases of recurrence. Results Patients underwent 1–9 years of breast cancer surveillance, with a median of 4.24 years. 390 (62.7%) patients underwent additional breast US surveillance to mammography. 232 (38.3%) fit criteria for use of additional breast US. 199 abnormal imaging episodes occurred, leading to 16 screen detected-cases of locoregional recurrence. US alone generated 107 abnormal images and found 9 cancers. US had a sensitivity of 44.1%, specificity of 95.2% and positive predictive value of 11.7% in comparison to mammography; 20.6%, 97.4% and 9.9% respectively. US had a biopsy rate of 4.0% and lead to an incremental cancer detection rate of 0.38%. The cost of incremental cancer found was $31,463.72 AUD. Survival outcomes based on method of detection of recurrence were insignificant (p value = 0.71). Conclusions Breast US has a sensitivity of 44.1% and detected seven recurrences that were mammographically occult. Breast US has a similar PPV to mammography in surveillance. Breast US generated considerable biopsy rates and costs. Survival analysis was not able to detect any benefit of US detected cases of recurrence.

“…US did not yield a higher detection rate than mammography, although combined surveillance with US and mammography detected metachronous ipsilateral recurrence slightly earlier than mammography alone [51]. To our knowledge, there have been no studies comparing the accuracy of mammography and MR for surveillance of ipsilateral recurrences in patients after BCS with RT.…”

“…For this reason, ultrasonography has been accepted as an additional imaging to mammography. Park et al 19 in their study investigating the effectiveness of US and MG in detecting ipsilateral metachronous tumors in patients who underwent BCS, they found a similar effectiveness of US and mammography in detecting recurrence (84.2% vs. 85.7%; P=0.898, respectively). They also reported that the effectiveness of US and mammography in detecting recurrence when used together was higher than mammography.…”

Aims: In patients undergoing breast-conserving surgery (BCS), the traditional follow-up imaging methods of the breast are mammography and ultrasonography. However, after BCS and radiotherapy, it becomes more difficult with imaging methods to detect the presence of recurrence or secondary focus due to the change of normal breast structure in patients. In this study, we aimed to investigate the sensitivity, specificity and malignancy prediction values of imaging methods in the follow-up of patients who underwent BCS. Methods: 421 patients diagnosed with breast cancer who underwent BCS were retrospectively analyzed. 63 patients with histopathology results, which were categorized as BI-RADS 4 or 5 according to imaging findings in their follow-up after BCS, were included in the study. The age of diagnosis, time taken for biopsy and mammography, ultrasonography and magnetic resonance imaging findings were recorded. Patients were divided into 2 groups (benign and malignant) according to the results of biopsy. According to the pathology results, sensitivity, specificity, positive and negative predictive values and diagnostic accuracy levels of radiological imaging findings were calculated. The significance of the difference between pathology groups in terms of mean age of diagnosis and biopsy time was evaluated by Mann-Whitney U test. Categorical variables were assessed by Yates test or Fisher's exact test. Results: Of the 63 patients, 49 (77.7%) were benign and 14 (23.3%) were malignant. There was a significant difference between the two groups in mass finding on mammography and posterior acoustic shadowing on US (p=0.011, p=0.049, respectively). Conclusion: MRI is the most sensitive imaging method in post-BCS follow-up and mammography is the most specificity imaging method. The finding with the highest positive predictive value for malignancy detection is the presence of mass on mammography and posterior acoustic shadow on ultrasonography.

Breast ultrasonography for detection of metachronous ipsilateral breast tumor recurrence

Abstract: The overall MIBTR detection rate by US was not higher than the detection rate of mammography, although combined surveillance with US and mammography found MIBTRs slightly earlier than mammography alone.
