简要总结
Complete removal of cancer encircled by a secure margin of healthy tissue is the aim of surgical oncology. A close or positive surgical margin reported by pathologist typically ends in adjuvant therapies (re-surgery and/or radiotherapy), which come with prognostic risks and financial cost. Therefore, ex-vivo imaging of removed cancer tissue may assist in margin evaluation. In this study, investigators aimed to investigate the correlation of 3D ultrasound to histopathology to assess tongue tumor margin status.

结局指标
主要结局
Diagnostic accuracy
时间窗: 2 weeks
number of margins correctly classified as free (\> 5 mm), close (\< 5 mm) or positive (\<1 mm) margin
Correlation of the surgical margin measurements of the 3D ultrasound to histopathology
时间窗: 2 weeks
The smallest margin will be measured in mm on 3D ultrasound image of the ex-vivo surgical specimen. Correlation of the measurement to the final histopathology result will be investigated.
