There has been recent interest in the use of Intensity Modulated Radiation Therapy (IMRT), a form of focal external beam radiation for intact cervical cancer. IMRT has been proposed as (1) an alternative treatment of the whole pelvis in an attempt to reduce the dose of radiation delivered to normal tissues and (2) a replacement for brachytherapy as an integrated or sequential radiation boost instead of intracavitary brachytherapy. At other tumor sites, IMRT has allowed for radiation dose escalation to the tumor while sparing adjacent normal tissues. IMRT requires greater accuracy of targeting and understanding of tumor and organ motion and tumor regression during radiotherapy to protect adjacent normal tissues and prevent against tumor underdosage.
