RESUMO
OBJECTIVE: To report the application of oncoplastic breast conserving surgery(OBCS) in China.METHODS: The survey was performed by using questionnaire in 110 breast surgery centers in China,whose annual breast cancer surgery volume over 200 in 2017.The surgery application situation and its relevant factors were analyzed.RESULTS: In2017,total 8443 cases of OBCS were performed in sample hospitals.OBCS occupied 9.8% of total breast cancer surgery and 43.4% of total breast conserving surgery(BCS).OBCS application showed extremely uneven among different hospitals.Both the number of hospitals whose OBCS/BCS>50% or <10% were 36(32.7%).Hospital's breast surgery volume had significant relevance with proportion of OBCS in BCS(P=0.006).The application rate of volume displacement was significantly higher than that of volume replacement(60.1% vs.15.2%,P<0.001).Geological distribution,GDP,hospital level or category showed no significant relevance with the OBCS application.CONCLUSION: The present scale of OBCS usage are uneven in China.Breast surgeons should receive more oncoplastic skills training,strengthen the concept of oncoplastic surgery and improve the multidisciplinary cooperation.
