Purpose: Alveolar rhabdomyosarcoma that harbors the PAX3/FOXO1 fusion gene (t-ARMS) is a common and lethal subtype of this childhood malignancy. Improvement in clinical outcomes in this disease is predicated upon the identification of novel therapeutic targets. Experimental Design: Robust mouse models were used for in vivo analysis, and molecular studies were performed on xenografts treated in parallel. Two independent patient sets (n=101 and 124) of clinically-annotated tumor specimens were used for analysis of FANCD2 levels and its association with clinical and molecular characteristics and outcomes. Results: Our xenograft studies reveal a selective suppression of FANCD2 by m-TOR kinase inhibition and radiosensitization of the t-ARMS line only. In the initial patient set, we showFANCD2 transcript levels are prognostic in univariate analysis, and are significantly associated with metastatic disease and that the co-presence of the translocation and high expression of FANCD2 is independently prognostic. We also demonstrate a significant and non-random enrichment of mTOR-associated genes that correlate with FANCD2 gene expression within the t-ARMS samples, but not within other cases. In the second patient set, we show that, on a protein level, FANCD2 expression correlates with PAX3/FOXO1 fusion gene and is strongly associated with phospho-p70S6K expression in cases with the fusion gene. Conclusions: Our data demonstrate that FANCD2 may have a significant role in the radiation resistance and virulence of t-ARMS. Indirectly targeting this DNA repair protein, through mTOR inhibition, may represent a novel and selective treatment strategy.
