Abstract:
The depth of invasion is a new index in the 8th edition of TNM classification and staging of oral cancer. Currently, there is no standardized evaluation method for the diagnosis of bone invasion and depth of invasion in lower gingival squamous cell carcinoma (LGSCC). The evaluation of LGSCC bone invasion depth not only provides a reference for surgical margin, but also determines the choice of surgical method, and is an independent prognostic factor for predicting cervical lymphatic metastasis. At present, the main evaluation methods of LGSCC bone invasion and invasion depth include X-ray, MRI, CT, positron emission tomography(PET)/CT, PET/MRI, singlephoton emission CT(SPECT)/CT and pathological examination. In this paper, the evaluation methods and effects of LGSCC bone invasion and invasion depth are summarized, and its advantages and disadvantages are analyzed in order to provide reference for clinical application.
