In patients with incomplete or out-dated staging at the time of radical radiotherapy, 11% will harbour occult metastatic disease and 25% will have undetected nodal disease. Timely and comprehensive baseline staging is of It is critical importance to ensure appropriate treatment and accurate target volume delineation.
