Abstract
최근 들어 새로운 방사선치료법인 강도변조방사선치료가 많은 종류의 종양치료에 적용되어 치료에 따른 부작용을 줄이고 치료율을 향상시키려는 노력들이 이루어지고 있다. 특히 전립선암에서 강도변조방사선치료법을 적용하여 삼차원입체조형치료에 비해 향상된
선량분포와 이로 인한 주위 정상조직의 방사선량을 줄임으로써 더욱 많은 양의 방사선을 전립선에 투여할 수 있고 이로 인하여 치료율의 상승을 기대할 수 있게 되었다. 저자들은 강도변조방사선치료를 전립선암에 적용하였기에 이에 대한 문헌고찰과 함께
치료과정을
보고하고자 한다.
This study was done to implement intensity-modulated radiation therapy (IMRT) for the treatment of primary prostate cancer and to compare this technique with conventional treatment methods. A 72-year-old male patient with prostate cancer stage
T2a
was
treated with IMRT delivered with dynamic multi-leaf collimation. Treatment was designed using an inverse planning algorithm, which accepts dose and dose-volume constraints for targets and normal structures. The IMRT plan was compared with a
three-dimensional (3D) plan using the same 6 fields technique. Lower normal tissue doses and improved target coverage were achieved using IMRT at current dose levels, and facilitate dose escalation to further enhance locoregional control and
organ
movement during radiotherapy is an important issue of IMRT in prostate cancer.
