European Radiology: Multi-parameter MRI to evaluate the depth of tumor invasion of oral tongue squamous cell carcinoma

Oral squamous cell carcinoma is the eighth most common cancer in the world, mostly occurring in the front 2/3 of the tongue
.

Oral tongue squamous cell carcinoma (OTSCC) developed due to the presence of the lymphatic vascular system and the lack of a strong barrier to tumor propagation, and therefore the prognosis is poor

Oral squamous cell carcinoma is the eighth most common cancer in the world, mostly occurring in the front 2/3 of the tongue

The depth of invasion (DOI) is defined as the distance from the mucosal surface or basement membrane to the deepest level of invasion, which is essential for clinically obtaining a sufficiently deep cancer-free margin

Due to its excellent soft tissue resolution, magnetic resonance imaging (MRI) is widely used to evaluate the clinical DOI of OTSCC

Recently, published in the E uropean a journal Radiology study to evaluate and compare various MRI sequences DOI accuracy in terms of estimated OTSCC to define the optimal sequence DOI clinical evaluation , at the same time to determine the optimal cut -off value , based on MRI The T staging standard established the clinically applicable T staging of OTSCC .
 

This study retrospectively analyzed 122 patients with oral tongue squamous cell carcinoma (OTSCC), all of whom underwent preoperative MRI scans and surgical resection

DOI from e-HRIVE showed the best correlation with pathological DOI (r = 0.
