ASO Author Reflections: The Completion May Lead to Conservation: Partial and Complete Intraoperative Ultrasound Enhanced Breast-Conserving Surgery for Invasive Breast Cancer

While the widespread adoption of the 2014 SSO-ASTRO Consensus Guideline led to a decrease in reoperation rate, a second surgery is still required in approximately one-tenth to one-fifth of the cases following breast-conserving surgery. 1 Additionally, a considerable number of experts argue that the definition of a negative surgical margin should be revised. 2ltering the "no ink on tumor" standard, however, is likely to affect reoperation rate or lead to unnecessary removal of healthy breast tissue.Intraoperative ultrasound (IOUS) is an established yet underutilized method for localizing breast lesions.IOUS was also shown to be able to guide tumor resection in real time. 3Moreover, it can be used to examine the surgically removed specimen for both tumor involved and close margins. 4The versatility of IOUS is undoubtedly a key factor in its effectiveness.On the other hand, this characteristic has also generated substantial differences in IOUS methodology.We retrospectively investigated how the extent of IOUS FUNDING Open access funding provided by Markusovszky Teaching Hospital of County Vas.
