PG - 192-204 LID - 10.3109/15513815.2012.701266 [doi] AB - Based on the cancer stem cell (CSC) concept model, a small population of cells with unique self-renewal properties and malignant potential exists in tumors. Immunohistochemistry was performed to detect the expression of CSC markers, CD133 and CD44, in a series of pediatric tumors. The association between expression of these markers and tumor characteristics was then analyzed. In Wilms tumors (WT), a significant positive correlation was found between expression of CD133 and the National Wilms Tumor Stage (NWTS) (p = 0.047). In neuroblastomas (NB), expression of CD133 was positively correlated with the International Neuroblastoma Staging System (INSS) (p-value = 0.012), indicating that the rate of CD133 positivity increased with the stage of these tumors. CD133, as a putative stem cell marker, is associated with more advanced stages of Wilms and NB tumors; therefore, this molecule can be a potential clinical prognostic marker in children suffering from NB or Wilms tumor.
