Clinical experience with intensity-modulated radiation therapy (IMRT) for XXXX with the use of rectal balloon for prostate immobilization.

@entity5 @entity1 @entity137 @entity263
The implementation of intensity-modulated radiation therapy (IMRT) is the result of advances in imaging, radiotherapy planning technologies, and computer-controlled linear accelerators. IMRT allows both conformal treatment of @entity5 and conformal avoidance of the surrounding normal structures. The first @entity1 treated with Peacock IMRT at Baylor College of Medicine took place in March 1994. To date, more than 1500 @entity1 have been treated with IMRT; more than 700 @entity1 were treated for @entity263 . Our experience in treating @entity263 with IMRT was reviewed. @entity1 and prostate motions are important issues to address in delivering IMRT. The Vac-Lok bag-and-box system, as well as rectal balloon for immobilization of @entity1 and prostate gland, respectively, are employed. Treatment planning also plays a very important role. IMRT as a boost after conventional external beam radiotherapy is not our treatment strategy. To derive maximal benefits with this new technology, all @entity1 received full course IMRT. Three separate groups of @entity1 receiving (1) primary IMRT, (2) combined radioactive seed implant and IMRT, and (3) post-prostatectomy IMRT were addressed. Overall, @entity137 profiles in these @entity1 were very favorable. IMRT has the potential to improve treatment outcome with dose escalation while minimizing treatment-related @entity137 .
