Brief summary
This study is the first prospective randomized study assessing the safety and patient-reported outcomes of immediate one-stage IBBR compared with those of two-stage IBBR with TiLoop® Bra.
Detailed description
Studies comparing two-stage implant-based breast reconstruction with immediate one-stage implant-based breast reconstruction have inconsistent results and investigators find that there is a lack of high quality evidence focusing on comparing one-stage and two-stage implant-based breast reconstruction with TiLoop®Bra. This study is the first prospective randomized study assessing the safety and patient-reported outcomes of immediate one-stage IBBR compared with those of two-stage IBBR with TiLoop® Bra in breast cancer patients. The hypothesis is that one step method is not inferior to two step method in implant based breast reconstruction following skin-sparing and/or Nipple-sparing mastectomy using TiLoop® Bra. The current study is a randomized multicenter, open labeled, prospective, controlled study. Participants were enrolled at six hospitals in different places of China. All participants will undergo Skin Sparing Mastectomy(SSM)/Nipple Sparing Mastectomy(NSM) with one-stage or two stage IBBR with TiLoop® Bra. Based on earlier experience, investigators calculated that the surgical complication rate was approximately 30 percent in the one-stage group and 25 percent in the two-stage group. Consider a dropout rate of 5%, a total of 450 patients, with 225 in each group, are needed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of perioperative complications | Start of randomization until 3 months after surgery | The rate of perioperative complication between the two groups |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Additional surgery | 18 months after surgery | The type of additional surgery following breast reconstruction |
| Quality of life:EORTC QLQ C30 /+ BR23 questionnaire | 18 months after surgery | EORTC QLQ C30 /+ BR23(EORTC breast cancer-specific quality of life) questionnaire to evaluate quality of life. Participants report the extent to which they have experienced those symptoms or problems during the past week. Each of the symptoms or problems is indicated with four extents, including not at all for 1 score,a little for 2 score, quit a bit for 3 score and very much for 4 score. A higher score indicated a worse quality of life. |
| Patient satisfaction:Breast-Q questionnaire | 18 months after surgery | Breast-Q questionnaire to evaluate patients' satisfaction Using the reconstruction module of BREAST-Q to evaluate patient-reported outcome (PRO) of the surgery.For each subtheme, one or more BREAST-Q scales were developed to examine specific aspects of patient satisfaction. Patient responses to each scale's items are transformed through the Q-Score scoring software to provide a total scale score that ranges from 0 to 100. For all BREAST-Q scales, a higher score means greater satisfaction. |
| Aesthetic score of reconstructed breast | 18 months after surgery | Harris evaluation system to evaluate patients' breast aesthetic after surgery. Harris evaluation system is a 4-staged subjective evaluation method scored as excellent, good, fair, poor . |
| Angiopathology-related assessment of Tiloop bra | 18 months after surgery | The angiopathology-related assessment in immediate-delayed reconstruction group |
