Summary

This study was designed to test a surgical navigation system that gives surgeons an extra view of chest wall lesions during surgery. The goal was to help remove tumors more precisely, reducing the need for repeat surgeries or complex reconstruction. However, the study was withdrawn before enrolling any participants, so no results are available.
