Intraoperative ultrasound (IOUS) is a potentially useful adjunct to the resection of oral tongue cancers (OTC). IOUS images of the tumor-normal tissue interface show different patterns of invasion. In this retrospective series of 29 patients treated for OTC, we evaluated if there was a correlation between IOUS findings of patterns of invasion and final histology and assessed if there was any associated risk of increased incidence of positive or close margins with different patterns of invasion as seen on ultrasound. Although we found no significant correlation between ultrasound patterns of invasion and histological evaluation, we did find that an infiltrative pattern of invasion on IOUS did result in a significant risk of a close margin. Further exploration of these findings in a larger prospective study could provide definitive information on the efficacy of this modality in OTC resections.
术中超声（IOUS）是一种可能有助于切除口腔舌癌（OTC）的辅助手段。IOUS 图像显示肿瘤-正常组织界面的不同浸润模式。在这项回顾性的 29 例 OTC 治疗患者的系列研究中，我们评估了IOUS 浸润模式的发现与最终组织学之间是否存在相关性，并评估了不同超声浸润模式是否会增加阳性或切缘接近的风险。尽管我们没有发现IOUS 浸润模式与组织学评估之间存在显著相关性，但我们确实发现IOUS 上的浸润性浸润模式确实显著增加了切缘接近的风险。在更大的前瞻性研究中进一步探讨这些发现，可以为IOUS 在 OTC 切除中的疗效提供明确的信息。
