Abstract
Intraoral ultrasound to measure tumor thickness and depth of invasion in oral cancer: narrative review
Highlights
AIMOral Squamous Cell Carcinoma (OSCC) tends to invade the surrounding tissue and to metastasize to the regional neck lymph nodes (local metastasis), while its incidence of haematogenous metastasis (distant metastesis) is infrequent and late
A search was performed using PubMed (MEDLINE), Embase and Cochrane databases, for original articles published from June 1990 to February 2018
The following keywords were used in combining more keywords: “ultrasound, ultrasonography, sonography, intraoral, oral cancer, oral tongue carcinoma” and the Boolean operators “AND” and “OR”
Summary
Oral Squamous Cell Carcinoma (OSCC) tends to invade the surrounding tissue and to metastasize to the regional neck lymph nodes (local metastasis), while its incidence of haematogenous metastasis (distant metastesis) is infrequent and late. For this reason, the surgical treatment of the primary tumor cannot be considered complete without the neck evaluation. The management of patients with early stage OSCC, with clinical negative lymph nodes involvement, is still controversial. A precise preoperative assessment of the Tumor Thickness (TT) and Depth Of Invasion (DOI) would provide useful information for targeting patients in need to elective treatment of the neck. The literature evaluation will be carried out based on expert opinion
