| Popis: | The objective of this study was to investigate the correlation between magnetic resonance imaging (MRI) characteristics of cervical lymph nodes and the pathologically confirmed status of cervical lymph node metastasis (LNM) in oral squamous cell carcinoma (OSCC) and to provide imaging evaluation parameters for the clinical diagnosis of cervical lymph node status in OSCC.In a retrospective analysis, 79 patients who were first pathologically diagnosed with OSCC were included. The MRI-derived imaging parameters of the cervical lymph nodes were evaluated and the pathological status of lymph nodes in neck dissection specimens was reviewed. The relationship between the imaging parameters and cervical LNM was analyzed.The MRI-derived imaging parameters of 4419 lymph nodes were evaluated, and the pathological status of 2463 lymph nodes was reviewed. The MRI-derived shortest axial diameter (SAD) and unclear boundary of the cervical lymph node were significantly related to LNM. The cutoff value of SAD that enabled identification of LNM was 3.6 mm, and it was 4.2 and 4.1 mm for the prediction of overall survival and disease-specific survival, respectively.The MRI-derived parameters SAD and unclear boundary of the cervical lymph node correlated with LNM in OSCC. MRI-derived SAD larger than 3 mm warrants simultaneous neck dissection at initial surgery. |
