Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the current protocol, application of 3D ex-vivo ultrasound, MRI, and clinical evaluation (palpation and examination) by the surgeon is proposed to analyze the margin status in tongue squamous cell carcinoma and correlate the results to the histopathology findings.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cancer surgery is the primary treatment in the early stages of tongue squamous cell carcinoma (SCC), and the goal is the complete resection of the tumor with an adequate margin of healthy tissue around to ensure proper cancer removal. Inadequate margins lead to a high risk of local cancer recurrence and the patient will need re-surgery or adjuvant therapies. Ex-vivo imaging of the resected surgical specimen has been suggested to provide information for margin assessment and thus improve cancer surgery. In this manuscript, a protocol to investigate the clinical benefit of three-dimensional (3D) ultrasound imaging of the surgical margins and comparing the results to magnetic resonance imaging (MRI) and the clinical examination of the surgical specimen by surgeon (palpation to inspect the resected tissue) has been designed. Tumor segmentation and margin measurement (Anterior towards apex of tongue, posterior towards base of tongue, medial towards back of tongue, lateral towards floor of mouth, and profound/deep margins) will be performed by head and neck surgeons on 3D ultrasound images and by two consultant radiologists on MRI of the ex-vivo specimen. Accuracy of each method will be evaluated by computing the proportion of correctly classified margins (positive, close, and free) by each technique with respect to the gold standard histopathology.

Tongue tumor resection

Group Type EXPERIMENTAL

3D ultrasound, MRI, resected specimen examination by surgeon

Intervention Type DIAGNOSTIC_TEST

3D ultrasound and MR scanning of the resected tongue tumor will be performed. The resected surgical specimen will also be examined by the surgeon to assess the margins. The accuracy of the margin assessment by 3D ultrasound, MRI, and surgeon examination will be evaluated by correlating the results to the final histopathology findings.
