Hedgehog pathway signaling in cervical carcinoma and outcome after chemoradiation

BACKGROUND: Hedgehog (Hh) signaling was assessed in patients with primary cervical carcinoma who were receiving chemoradiation. Because the up-regulation of Hh has been reported in response to hypoxia, the authors examined associations between Hh gene expression and measurements of HP5 (the percentage of oxygen pressure readings in each tumor
