Megavoltage CT/MRI-Guided Radiotherapy with Endorectal Balloon Support for Prostate Cancer Patient with Bilateral Hip Prostheses

Yukihiro Hama, Etsuko Tate

Abstract


Introduction: Kilovoltage CT-guided radiotherapy for prostate cancer patients with bilateral hip prostheses can be challenging due to metal artifacts.

 

Case Presentation: To compensate for reduced tissue contrast and suppress metal artifacts, a 76-year-old NCCN very high-risk prostate cancer patient underwent megavoltage CT/MRI fusion image-guided radiotherapy with an endorectal balloon. The post-treatment course was uneventful. There were no recurrences or serious side effects 11 years after radiotherapy.

 

Conclusions: Megavoltage CT/MRI-guided radiotherapy with endorectal balloon support may be a viable alternative for a prostate cancer patient with bilateral hip prostheses.
