Purpose: Survey the rate and distribution of retropharyngeal lymph node metastasis, the suitability between Magnetic Resonance and computed tomography in the evaluation of nasopharyngeal tumor and the ability to detect retropharyngeal lymph node. Methods and Materials: Cross-sectional descriptive study conducted on 35 patients with nasopharyngeal carcinoma diagnosed and treated at Hue Central Hospital from April 2018 to July 2019. The patient underwent Magnetic Resonance Imaging and Computed Tomography. Data processed with SPSS 20.0 for Windows. Investigate the level of correlation between the two techniques based on the Kappa coefficient. Results: 14 patients had retropharyngeal lymph node metastasis with a total of 25 lymph nodes, all of which in the lateral position, none in the middle. 76% the lymph nodes are at the level of C1 vertebra. 48% of lymph nodes have heterogeneous enhancement. There is a close match between Magnetic Resonance Imaging and Computed Tomography in assessing the invasion at anatomical positions: Rosenmuller fossa, Eustachian tubes, nasal cavity, pharynx, and paranasal sinuses; There is a moderate match between the two methods in assessing the invasion of the cranial base and the sphenomaxillary suture. In 14/35 cases where the retropharyngeal lymph node was detected on Magnetic Resonance Imaging (accounting for 40%), Computed Tomography identified only 6 cases (17.1%). Conclusions: There are differences on many levels between Magnetic Resonance Imaging and Computed Tomography in the diagnosis of tumor invasion and retropharyngeal lymph node metastasis in nasopharyngeal carcinoma. In particular, Magnetic Resonance Imaging is better in detecting retropharyngeal lymph node metastasis due to high structural contrast, these lymph nodes are often difficult to detect on Computed Tomography because it is difficult to distinguish from posterior pharyngeal structures or tumors.

BackgroundTo assess the prevalence, risk factors and prognostic significance of retropharyngeal lymph node (RPLN) metastasis diagnosed by magnetic resonance imaging (MRI) in patients with hypopharyngeal squamous cell carcinoma (HPSCC).Methods259 patients from three cancer institutions in China from Jan 2010 to Dec 2018 were analyzed, retrospectively. All the patients had been given pre-treatment magnetic resonance imaging (MRI) of head and neck and were then treated with definitive radiotherapy with or without chemotherapy. Pretreatment diagnostic MRIs were reviewed by a dedicated head and neck radiologist, for the presence or absence of radiographically positive RPLN, cervical LN and tumor invasion.Demographic variables were analysed by descriptive statistics using SPSS 20.0. Predictors of the presence of RPLN and its prognostic significance were examined.ResultsRPLN metastasis was discovered in 44 patients (17%). Logistic analysis showed that posterior pharyngeal wall (PPW) primary tumor; PPW invasion; N2-3; multiple cervical lymph node (LN) involvement (>2 LNs) were associated with RPLN metastasis, with metastasis rates 37%, 30%, 31% and 33% respectively. Patients with RPLN metastasis had a significantly reduced 5-year overall survival (OS) and disease-free survival (DFS) compared to the non-RPLN metastasis group (OS 28% vs. 48%, p=0.001; DFS 25% vs. 41%, p=0.040).ConclusionsRPLN metastasis was not uncommon in HPSCC patients. Risk factors were: PPW primary tumor, PPW invasion and cervical LN status. RPLN metastasis is a poor prognosticator for survival.
