The Chart Diagnostic System Improves the Diagnostic Accuracy of Cervical Lymph Node Metastasis in Oral Squamous Cell Carcinoma

Purpose: To establish a diagnosis method based on imaging findings and histopathological factors associated with cervical lymph node metastasis. Methods: A total of 1587 nodes that were detected using tools in 73 OSCC patients who underwent surgical treatment enrolled to evaluate the association between (long diameter, short long–short ratio, US (hilum internal echo), contrast effect enhanced CT, standardized uptake value (SUV) max SUV average 18F FDG-Positron Emission Tomography (PET)) metastatic nodes. In 57 patients, biopsy specimens evaluated for histopathologic (budding score, lymphatic invasion, vascular nerve YK classification) presence metastases. Cervical metastasis was determined examination no observed 3 years after primary surgery. Results: total, 22 had pathologically. comparison nodes, univariate analysis showed significant differences long long/short echo, rim enhancement, max, average, budding invasion. Multivariable score. Conclusions: We propose chart diagnostic system combines improve
