| Research Abstract |
The purpose of the study was to develop high precision radiotherapy considering the risk of recurrence and complication and to promote the personalized treatment for uterine cervical cancer. The major research included image-guided brachytherapy (IGBT) for primary tumor, control of pelvic lymph node metastases, and comparison of intensity-modulated radiotherapy (IMRT) with conventional 3D conformal radiotherapy.
In the IGBT, increasing or decreasing of point A dose balanced sufficient dose between rectum and target. In case of irregular-shaped bulky tumor, hybrid brachytherapy consisting of conventional application and interstitial needle was effective to cover the tumor with sufficient dose while sparing the rectal dose. We also clarified the pelvic control dose and the sparing effect of small intestine and pelvic bone doses by IMRT.
