Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Ultrasound will also be used during surgery of the tumour to investigate if it is useful to better decide the depth of the tumour and thereby improving the operation.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The examiner, one of three otorhinolaryngologists experienced in ultrasound, should be masked to the results of MRI. The first measurement is depth of invasion as well as thickness of the tumour in mm by palpation on awake patient. Thereafter the same measurements by ultrasound (BK Medical Medical flex focus 500, 18Mhz) with gel and protective cover is made with 0,5mm accuracy. Anesthetic gel or lingual block with carbocaine/adrenaline are provided as needed.
At the time of surgery the measurements above are done again on the patient in narcosis before the resection.
Images of the ultrasound measurements are saved for documentation. The results are compared to the corresponding measurements on MRI and also on PAD from the surgical specimen. PAD is considered gold standard.
Power calculation with help of biostatistician yielded a sample size of 55 patients, using a paired test with a 0,050 one-sided significance level will have 80% power to reject the null hypothesis that the proportions are not equivalent.
Analysis if ultrasound correctly classify the tumour´s DOI according to the TNM-classification 8th edition (\<5mm, \>5mm\<10mm, \>10mm) will be made.
The second part of the study will investigate if ultrasound during the surgical procedure can improve the discrimination of the deep margin of the tumour and thereby increasing the chance better surgical margins. The mucosal margins are marked in the usual fashion and the resection begins. After one fourth of the resection has been made, ultrasound is used to check that the deep margin is at least 10mm. This is repeated after one half and three quarters of the resection. At the end of the surgery a final ultrasound examination is made on the surgical specimen.
The margins obtained on PAD from resections done with ultrasound are compared to a matched retrospective group where the surgery was done without ultrasound.
After inclusion started our group started cooperation with another biostatician whom judged the analysis better be done from the quantitative variable of DOI in millimeter. This meant the power analysis shifted and a study population of between 15-23 participants was considered sufficient. Since the original plan was 55 participants we kept that number but after an interim analysis in may 2021 a total of 42 participants is now what we consider relevant in the study of DOI.
In our second endpoint studying ultrasound and surgical margin the interim analysis concluded that collection of patients for 2 years (may 2019 until may 2021) will be compared to a historical control group 4 years back in time (may 2015 until may 2019) and therefore the inclusion of that data stopped in may 2019.

Study Groups

ultrasound assisted resection
resection of tongue cancer will be done with assistance of ultrasound to visualise the deep margin.
Ultrasound
enrolled patients will be investigated by ultrasound two times, awake in the clinic and in narcosis before the surgery. For those with tongue cancer ultrasound will be used during the surgery to visualise the deep margin of the tumour.
