Brief summary

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.

Detailed description

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.

Interventions

Immediate Autologous/prosthetic-based breast reconstruction is performed after mastectomy on the breast that is diagnosed with breast cancer

Delayed Autologous/prosthetic-based breast reconstruction is performed after mastectomy on the breast that is diagnosed with breast cancer

RADIATIONRadiation

Radiation is performed to the surgical site and complies with the ASCO guidelines on post-mastectomy radiotherapy

Design outcomes

Primary

MeasureTime frameDescription
occurrence of short term complicationsthe short term complications will be inspected up to 3 months post-op;impaired arterial or venous flap perfusion by increased (\>3 seconds) or reduced (\<2 seconds) capillary refill time; infection of the reconstructed breast with evidences from microbiological cultures; partial or entire flap necrosis with evident demarcation by clinical observation
occurrence and change of long term complicationsthe long term complications will be assessed at 6 months post-op; repeated assessments will be made at 12 and 24 months to record changesfat necrosis proven by breast ultrasound/ breast MRI/ pathology; flap contracture that causes change in shape and/or volume in the reconstructed breast mound observed by naked-eye inspection or breast imaging; capsular contracture that causes hardness/pains or changes of the reconstructed breast mound observed by surgeon's inspection or breast imaging.
occurrence of secondary surgeryup to 24 months post-opunplanned surgery due to short-term and/or long-term complications post-op, the types of secondary surgery include but not limited to exploratory surgery, flap salvages, removal or fat necrosis, debridement, prosthetic explantation.

Secondary

MeasureTime frameDescription
occurrence of revision surgery6 to 24 months post-opany surgery performed to the reconstructed or contralateral breast to optimize symmetry
baseline and change of subjective evaluationthe baseline evaluation will be made at 6 months post-op; repeated evaluations will be made at 12 and 24 months to record changespatient 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.
