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.

Thirteen patients with head and neck cancer underwent staging by clinical examination, computed tomography (CT), and magnetic resonance imaging (MRI) in a standardized blinded fashion. All patients subsequently underwent radical neck dissection with subsequent pathologic staging. CT and MRI each predicted 93% of staging results correctly, with clinical examination correct 67% of the time. Staging of primary tumors had an accuracy of 90% by clinical examination, 40% by CT, and 50% by MRI when compared to staging of the pathologic specimen. Understaging was seen in 50% of CT scans and 30% of MRI scans. We believe either CT or MRI should be considered for routine staging of the neck in all head and neck malignancies.

Abstract We evaluated 56 consecutive patients with newly diagnosed lymphoma including 48 with non-Hodgkin's lymphoma (NHL) and 8 with Hodgkin's disease to determine the clinical and prognostic significance of magnetic resonance imaging (MRI) of the femoral marrow. MR images of the femoral marrow were obtained by the T1-weighted spin echo method and the short TI inversion recovery technique. Abnormal “positive” images were seen in 29 of the 56 patients (52%). All 17 patients with positive biopsy results showed abnormal images on their femoral marrow MRI. Three “positive” MRI patterns — scattered (72%), uniform (21%), and nodular (7%) — were observed. The overall survival of the patients with a positive MRI pattern was significantly poorer than that of patients with a normal pattern (P = .0129). Survival did not differ significantly according to MRI pattern. The 3-year survival rate in the patients with a normal MRI pattern was 89.9% and in the patients with a positive MRI pattern, it was 41.0%. This difference was statistically significant (P = .0279) when we evaluated only the patients with NHL. Patients with positive MRI patterns, but a normal bone marrow histology, showed a significantly shorter survival than those with a normal MRI pattern (P = .016). These results indicate that abnormal MR images of the femoral marrow are associated with a significantly poorer survival in patients with malignant lymphoma, regardless of histologic findings in the marrow.

The Brain

Infantile cerebral palsy (ICP) is the main cause of childhood disability and is characterized by a non-progressive lesion and/or impaired development of the brain in a foetus or newborn. Magnetic resonance imaging (MRI) is a modern non-invasive method with extensive capabilities for diagnosing brain damage in ICP. The review focuses on anatomical structural MR patterns of brain damage in ICP and gives the present-day classification of MR changes in this disease. The role of MRI in determining the duration of brain damage in ICP has been considered. Data on the ratio of ICP phenotypes to pathological MR findings has been presented. Neuroimaging prognostic biomarkers are discussed. It is emphasized that many questions regarding the prognostic significance of MR findings remain unresolved; prospects are associated with the use of new MRI modalities such as functional and diffusiontensor MRI.
