Use of Ultrasound for Measuring Size of Oral Tongue Cancers
Official Title
Use of Transoral Ultrasound for Measuring Depth Of Invasion in Oral Tongue Carcinoma, and Comparing Obtained Measurements With Measurements From MRI With the Results Obtained From Pathological Examination of Surgically Resected Specimens
Brief Summary
The purpose of this study is to investigate the use intraoral ultrasound for measuring depth of invasion (DOI) in oral tongue squamous cell carcinoma. The DOI's measured on ultrasound and measurements from MRI scans, will be compared to the measurements made from pathological examination of removed specimens.
Detailed Description
We will conduct a prospective cohort study to investigate the correlation between DOI measurements from preoperative imaging (MRI and intraoral ultrasound), and final histopathology findings. All patients with oral tongue cancer histologically verified on biopsy diagnosed in the Capital Region and Zealand Region (population 2.6 mio) are treated at the department of Head and Neck surgery at Copenhagen University Hospital (Rigshospitalet). These patients will be invited to participate in the study before or at their multidisciplinary team (MDT) conference at Rigshospitalet where the final treatment will be decided. The ultrasound exam is conducted with a bk5000 or bk3000 machine, a "Hockey Stick" X18L5s transducer or a 18L5s Linear transducer. The transducer will be placed directly on the tongue tumor. The tumor size will be measured, and depth of invasion will be estimated. For later reevaluation of the ultrasound images, a sweep will be performed, and image files and video clips will be stored for documentation. Patients will primarily be examined in the outpatient clinic, and the measurement will be repeated at the time of surgery when the patient is in general anesthesia. It is, however, at time of the examination outpatient clinic that the information about DOI is most useful in planning the treatment, and therefore this is measurement we will be focusing on. Each MRI scan will be reviewed by a radiologist and the DOI will be assessed if possible. According to the AJCC Cancer Staging System, 8th edition, "DOI is measured by first finding the 'horizon' of the basement membrane of the adjacent squamous mucosa. A perpendicular 'plumb line' is established from this horizon to the deepest point of tumor invasion" [AJCC ] We aim to include 30 Patients in this study. The annual number of patients in our clinic operated for oral tongue carcinoma is around 50, so we aim to include the 30 patients within one year.
