Comparing the Performance of Automated Breast Ultrasonography to Hand-Held Whole Breast Ultrasonography in Breast Cancer Treatment Response Assessment
Comparing the Performance of Automated Breast Ultrasonography (ABUS) to Hand-Held Breast Ultrasonography (WBUS) in Breast Cancer Treatment Response Assessment in a Tertiary Cancer Center: A Prospective Study
연구 개요
상세 설명
PRIMARY OBJECTIVE:
I. To estimate and compare the accuracy of automated breast ultrasonography (ABUS) and hand-held whole breast ultrasonography (WBUS) in predicting pathology complete response (pCR) with relative tumor volume change, using the receiver operating characteristic (ROC) curve analysis.
SECONDARY OBJECTIVES:
I. To evaluate the reproducibility of tumor volume measurements obtained by ABUS and handheld WBUS, respectively, using data collected at baseline for initial staging.
II. To assess the agreement in relative tumor volume change (RC) (end-of-treatment versus [vs.] pre-treatment) between ABUS and WBUS.
III. To estimate and compare the following diagnostic measures for ABUS and WBUS: sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV).
OUTLINE:
Patients undergo ABUS over 15 minutes followed by WBUS over 30 minutes at baseline, mid-treatment and pre-surgery (end of treatment).

Area under the receiver operating characteristic (ROC) curve
기간: through study completion, an average of 1 year
|
Will compute relative tumor volume change for both automated breast ultrasonography (ABUS) and hand-held whole breast ultrasonography (WBUS) and estimate pathology complete response ROC curves for each.
Will estimate the areas under the ROC curves along with 95% confidence intervals and then compare the values statistically.
