Effect of Radiation and Its Timing on Breast Reconstruction in Chinese Patients
2018年11月14日 更新者:Tianjin Medical University Cancer Institute and Hospital
A Multi-center Prospective Observational Trial Investigating the Effect of Radiation and Its Timing on Breast Reconstruction in Chinese Patients
The purpose of the study is to investigate the impacts of radiation and the timing of radiation on autologous and prosthetic-based breast reconstruction in Chinese post-mastectomy breast cancer patients.
The study aims to optimize the timing for autologous/prosthetic breast reconstruction which delivers the best aesthetic results while maintains low complication rate and best integrates into the comprehensive breast cancer treatment.
The study is open to all female breast cancer patients undergoing breast reconstruction in the department of breast reconstruction in Tianjin medical university cancer institute and hospital.

詳細な説明
In breast cancer patients, post-operative radiation therapy is an important component in breast cancer management.
However, in the context of breast reconstruction, radiation can have adverse effect as it increases the rate of fat necrosis and leads to fibrosis/ capsular contracture in the reconstructed breast mounds.
It is therefore necessary to investigate the best timing for breast reconstruction, especially in those patients which post-operative radiation is required, which does not interfere with overall breast cancer treatment while produces the best surgical, aesthetic and psychological outcome.
Most studies in this field are retrospective, and studies on Chinese cohort are also rare.
This multi-center prospectively designed clinical trial will include several medical centers across China.
The investigators will allocate the patients into three arms based on the status and sequence of radiation and breast reconstruction, and will further stratify the groups based on the different approaches of reconstruction (autologous/ prosthetic based).
Both objective and subjective (patient oriented) methods will be employed to make evaluations involving surgical, aesthetic, and psychological outcomes.

|
|
occurrence of secondary surgery
時間枠:up to 24 months post-op

時間枠 |
|---|---|---|
|
occurrence of revision surgery
時間枠:6 to 24 months post-op
|
any surgery performed to the reconstructed or contralateral breast to optimize symmetry

baseline and change of subjective evaluation
時間枠:the baseline evaluation will be made at 6 months post-op; repeated evaluations will be made at 12 and 24 months to record changes
|
patient oriented aesthetic, psychological and overall outcome evaluations are made with BREAST-Q (short for breast-questionnaire) post reconstruction module, the the selected questionnaire includes a set of questions regarding : category 1-patients' satisfaction with breasts; category 2-patients' satisfaction with outcome and category 3-patients' psychological well-being.
In each category, the total score is generated by Q-score (short for questionnaire-score)software and the total score ranges from 0-100.
The higher the score the better the satisfaction.
