B7-H1 Expression in Wilms Tumor: Correlation With Tumor Biology and Disease Recurrence

摘要

PurposeDespite tremendous gains in improving prognosis, 10% of patients with Wilms tumor will ultimately experience disease recurrence. The identification of novel prognostic markers and tumor associated targets for patients at risk could enable clinicians to treat recurrences more aggressively and, thus, optimize outcomes. We have previously shown that tumor expression of the T cell coregulatory ligand B7-H1 portends a poor prognosis for adults with renal cell carcinoma and represents a promising target to improve therapy. We hypothesize that this finding may be true for Wilms tumor.
