title: CD147 expression in uterine smooth muscle tumors, and its potential role as a diagnostic and prognostic marker in patients with leiomyosarcoma.
abstract: OBJECTIVE
  To investigate the role of CD147 expression in uterine smooth muscle neoplasms, as a potential diagnostic and prognostic marker in patients with leiomyosarcoma (LMS).
  
  
  METHODS
  We investigated CD147 protein expression in uterine smooth muscle tumor samples from patients diagnosed with leiomyoma (n = 22), atypical leiomyoma (BLM) (n = 5), smooth muscle tumor of uncertain malignant potential (STUMP) (n = 14), and LMS (n = 22). The intensity and extensity of immunohistochemical staining were compared to determine its potential role in differential diagnosis. Spearman's rank correlation tests were performed to determine the relationship between CD147 expression and prognostic clinical and pathological criteria in the patients with LMS.
  
  
  RESULTS
  CD147 was strongly expressed in 81.8% (n = 18) of the LMS tissue samples. In fact expression of CD147 in LMS tissues was significantly higher than that of the three other uterine smooth muscle tumor types (p = 0.000). However, high CD147 expression was found in only one BLM sample and one STUMP sample. Furthermore, CD147 percent expression positively correlated with Ki67 percent expression (r = 0.466, p<0.05) and mitotic index (r = 0.554, p<0.05), respectively.
  
  
  CONCLUSIONS
  Our results suggest that immunohistochemistry may be a helpful tool in determining whether CD147 is a useful marker in the differential diagnosis of certain uterine smooth muscle tumors. CD147 may also have prognostic value for patients with LMS. Yet, in order to determine the extent of this potential marker's utility as a diagnostic and prognostic indicator, a larger randomized multicenter study must be performed.
