Analysis of clinical features and outcomes for inflammatory XXXX in China: 11 years of experience at a single center.

@entity5 @entity1 @entity706
PURPOSE: @entity5 ( @entity5 ) is a rare benign @entity5 . The purpose of this study was to review the clinical characteristics, imaging and pathological features, and outcomes of @entity1 with IMTs from a single center in China. METHODS: A retrospective file review was conducted involving 23 cases of pathologically confirmed IMTs treated at the @entity1 's Hospital between April 2003 and April 2014. RESULTS: The @entity5 locations included multiple anatomic sites, as follows: abdomen or pelvis (n  =  17); lungs (n  =  2); head and neck (n  =  1); trunk (n  =  1); and extremities (n  =  2). The @entity5 were associated with various clinical presentations. The predominant symptoms included an anemic appearance, fevers, and an asymptomatic mass. Computed tomography scanning showed solid, heterogeneous, well-demarcated masses; the appearance of enhancement was variable. MRI appeared hypointense on T1-weighted images and hypointense or hyperintense on T2-weighted images. Immunohistochemical staining revealed @entity706 kinase was negative in 11 of 13 cases tested. One @entity1 quit treatment  for the unresectable mass after biopsy and died 2  years later, and another @entity1 with incompletely resection is alive at 30  months following chemotherapy. The remaining 21 cases had complete resections; one @entity1 died due to a recurrence, and the other 20 @entity1 survived and were @entity5 free. The follow-up ranged from 7 to 141  months, with a mean of 56  months. The 3-year OS was 88  % (95  % CI, 57-97  %). CONCLUSIONS: @entity5 is a benign @entity5 that rarely presents with malignant features. Complete resection is curative in most @entity1 . ALK+ is variable for diagnosis. Close follow-up is necessary for @entity1 who undergo surgical resection.
