Prognostic CT and MR imaging features in XXXX with untreated extranodal @entity1893 of the head and neck region.

@entity1 @entity75 @entity5 @entity3 @entity1893
OBJECTIVE: To determine the prognostic CT and MR imaging features of extranodal @entity1893 in the head and neck region. METHODS: The clinical data and CT and MR imaging features of 59 @entity1 with histologically confirmed extranodal @entity1893 in the head and neck region were retrospectively reviewed. Subjects included 27 male and 32 female @entity1 between 13 and 81  years of age, with a mean age of 60.3  years. The clinical outcomes were categorized according to whether relapse or @entity3 occurred within 2  years after therapy. The association between the clinical outcome and radiologic factors including @entity5 size, margin, shape, @entity5 invasiveness, regional lymph node involvement, number of involvement sites, and contrast enhancement patterns was determined using univariate and multiple logistic regression analysis. RESULTS: Radiologic factors including @entity5 size, margin, shape, and @entity5 invasiveness were associated with poor clinical outcomes, as determined by univariate analysis (P   <   0.05). Only the lesion margin category (ill-defined) remained an independent risk factor for clinical outcome in multivariate logistic regression analysis, with an OR of 8.14 (P   <   0.05). CONCLUSION: Ill-defined margin of the @entity75 was indicative of unfavourable survival outcome for @entity1 with extranodal @entity1893 of the head and neck region. KEY POINTS:     @entity5 size, margin, shape and @entity5 invasiveness were prognostically relevant.     @entity5 margin was an independent risk factor for clinical outcome.     Ill-defined margin of @entity75 was indicative of unfavourable survival outcome.
