AbstractObjective: To explore the current clinical practice of implant-based breast reconstruction (IBBR) in China. Methods: The current survey was sponsored by Chinese Anti-Cancer Association, Committee of Breast Cancer Society and Chinese Society of Breast Surgeons. A survey was mailed to 110 hospitals in China, which have more than 200 breast cancer operations performed in 2017. The survey mainly included questions on the clinical practice of IBBR, sociodemographic and geographical factors associated with IBBR practice, reasons and concerns for selecting IBBR, type and timing of breast reconstruction, and the complications of IBBR. Data were analyzed using χ(2) test, Fisher's exact test or Kruskal-Wallis rank sum test. Results: IBBR was available in 86.4% (95/110) included hospitals. It was predominantly performed breast reconstruction surgery, the proportion of IBBR in all the breast reconstruction was 65.75% (4 296/6 534). However, the rate of IBBR in all the patients received mastectomy was only 7.06% (4 296/60 877). Among all the included hospitals, the number of implant reconstructions performed in 2017 was 24 (57.5) cases (M(Q(R)), range: 2-565 cases). Factors associated with the performance of IBBR including regional per capita gross domestic product (H=10.47, P=0.005) and annual surgery volume (H=8.30, P=0.016). The main reasons for choosing IBBR were relatively simple surgical procedure, short learning curve and short operation time. The effects of adjuvant radiotherapy on prosthesis, postoperative complications and patient satisfaction were the main concerns for implant reconstruction. Compared with delay reconstruction, a higher proportion of IBBR was observed in immediate reconstruction (83.1% vs. 62.0%, χ(2)=12.522, P=0.000). In all, 10.5% (10/95) hospitals reported more than 10% grade Ⅲ to Ⅳ capsular contracture. The incidence of infections need surgical intervention was reported between 10% and 20% by 4.2% (4/95) hospitals. Hospitals with 6% to 10% implant rupture and 6% to 15% implant removal were 1.1% (1/95) and 4.2% (4/95) respectively. Conclusions: IBBR was the most common used surgery in breast reconstruction after mastectomy. However, the proportion of IBBR in patients after mastectomy was still low. Reginal economy, surgery volume of hospitals, lack of specialty training program and the concern about complications and patient's satisfaction were the factors affecting the development of IBBR.
