简要总结
This observational study aims to evaluate the safety and effectiveness of radiotherapy for subjects with localized T1-T2 prostate cancer in China who were injected with SpaceOAR Hydrogel, via collecting clinical data related to radiotherapy.
详细描述
This study protocol is for the second part of SpaceOAR real world study in which long term follow-up visits will be performed (up to 1 year) outside Boao Medical Tourism Pilot Zone. The SpaceOAR real world study is a retrospective and prospective, single arm, observational study (Ptotocol of SpaceOAR RWS Windchill#: 92743236). Subjects with localized T1-T2 prostate cancer who have already been injected with the SpaceOAR and have received radiotherapy or will receive radiotherapy will be enrolled, and clinical data related to radiotherapy will be collected. For subjects who have already completed radiotherapy before study kick-off, clinical data will be collected retrospectively, such as data related to radiotherapy, AE (if any) and MRI (if any). Follow up vist will be completed if applicable. For subjects who receive therapy after study kick-off, follow up visits at 2 weeks, 6weeks, 3 months and 10 months after radiotherapy will be scheduled to assess bowel, urinary and sexual function and quality of life.

结局指标
主要结局
Change of Dose Rectum Volume Receiving Radiation Between Radiotherapy Plannings Pre and Post SpaceOAR Hydrogel Injection.
时间窗: Post injection gel surgery 1-10 days
Change of dose rectum volume receiving radiation,which is measured by Dose-volume histogram in radiotherapy planning pre and post SpaceOAR hydrogel injection radiotherpy planning is made based on CT simulation scans.
次要结局
- Urinary, Bowel and Sexual Function Assessment Score(After the completion of radiotherapy, the month 3 Expanded Prostate Cancer Index Composite (EPIC)-26 score was compared to the baseline EPIC-26 score.)
- Quality of Life Was Measured by EQ-5D-5L Scale（the Five-level Version of the EuroQol 5-Dimension Scale)(After the completion of radiotherapy, the month 3 EQ-5D-5L scale（the five-level version of the EuroQol 5-Dimension scale) score was compared to the baseline EQ-5D-5L scale score.)
- The Distance Between Prostate and Rectum(After the completion of radiotherapy, the weeks 6 the distance between prostate and rectum measured by MRI was compared to the baseline the distance between prostate and rectum measured by MRI.)
- the Distance Between the Prostate and Rectum(After the completion of radiotherapy, the month 10 the distance between prostate and rectum measured by MRI was compared to the baseline the distance between prostate and rectum measured by MRI.)
- Adverse Event Related to SpaceOAR Hydrogel (Safety)(Through the entire study phase until 10 months after the completion of radiotherapy.)
