A Cost-Effective Handheld Breast Scanner for Use in Low Resource Environments: A Validation Study

Completed

• Conditions: Breast Cancer

• Registration Number: NCT02814292
• Lead Sponsor: University of Pennsylvania

Brief Summary

Validation of the PEFS to detect breast tumors will be performed by means of a prospective trial. Subjects will participate for 1 clinic visit. Readings from the PEFS will be studied for reproducibility and predictive ability. Data analysis will be iterative, moving on with each modification of the device until the final prototype is created.

Detailed Description

Phase 2A of this study is directed primarily at prototype development, creating, testing, and modifying a 4x4 finger array device with a small footprint that is battery powered and reliable. The testing in this phase is aimed at proving that modifications did not degrade the screening sensitivity of the original lab prototype.

Target enrollment is up to 100 patients to verify that the investigators have reproducible values in the same patient. Each breast will be evaluated and compared against each other whether it is considered normal or abnormal tissue. Data from patients both normal and abnormal regions will be compared and used to determine predictive value and accuracy in this prototype. The patient population will be women and men 18 years of age or older with symptomatic breast lump either by palpation or imaging.

Symptomatic individuals scheduled to undergo diagnostic exam will be recruited from all patients presenting for breast evaluations at Dr. Brooks clinical practices who meet all the inclusion and exclusion criteria. Consent will be obtained prior to any study related activities. The PEFS evaluation will be performed by a trained individual. Subjects will be scanned in supine position without breast immobilization - similar to ultrasound testing. The PEFS data is recorded and processed by an automated software algorithm and the results are displayed topographically on a breast-map with red areas showing positive findings and black areas showing negative findings. Quantitative data will be documented and analyzed for accuracy metrics. Results will not be given to subjects nor recorded in their medical records. Because this study is not a clinical utility study, results will have no effect on clinical care decisions. The PEFS evaluation may add between 10 and 30 minutes to the clinic visit. No imaging or pathology tests are being done for research purposes.
