Near simultaneous computed tomography image-guided stereotactic spinal radiotherapy: an emerging paradigm for achieving true stereotaxy.
To report treatment setup data from an emerging technique using near-simultaneous computed tomography (CT) image-guided stereotactic radiotherapy for the treatment of spinal and paraspinal tumors. ⋯ Preliminary experience suggests that the near-simultaneous CT image-guided verification technique can be used as a new platform technology for extracranial applications of stereotactic radiotherapy and radiosurgery to spinal and paraspinal tumors.

Potential of intensity-modulated radiotherapy to escalate doses to head-and-neck cancers: what is the maximal dose?
To investigate the potential of intensity-modulated radiotherapy (IMRT) to escalate doses to head-and-neck cancer and find the maximal dose that could be prescribed to the target volume with IMRT while doses to critical organs were maintained at their currently acceptable levels. The secondary goal was to search for limits in current IMRT technology. ⋯ Doses to head-and-neck cancers with simultaneous integrated boost IMRT can be escalated to a greater level than currently prescribed clinically. The limit of IMRT in head-and-neck cancer has not been reached at the current prescription level of 70 Gy. Such high total and fractionated doses should be carefully evaluated before being prescribed clinically.
