Specific Radiation Therapy Approaches:
IMRT with radiosurgery boost, including CyberKnife
Some studies have shown that stereotactic radiosurgery (SRS) is an effective boost method for delivering additional radiation therapy dose to the nasopharynx tumor after initial therapy with IMRT. A ‘boost’ is treating a focal area with radiation to go to a higher dose. Focal radiation therapy with treatment machines like CyberKnife helps further spare surrounding normal tissue. It should be noted however that highly focal treatment with CyberKnife alone is generally not an option for NPC since it is crucial to commence therapy with broader field radiation to treat potential lymph node involvement in the neck in addition to covering the nasopharynx region.
