Objective To use multiple correspondence analysis (MCA) to obtain the influencing factors of receiving breast conserving surgery (BCS) for early breast cancer patients, so as to provide data supports for improving the adherence rate of BCS. Methods We collected the case data of early breast cancer patients who underwent BCS and mastectomy. Chi square tests were used to investigate the relationship between the influencing factors and operation methods in the contingency tables; the twodimensional graph of MCA was used to show the corresponding relationship between influencing factors and breast conserving surgery, and the influencing factors were determined according to the corresponding relationship between different factors and their different classifications in the graph. Results Totally 2 423 cases with early breast cancer were collected, and the rate of breast conserving surgery was 7.88%. The results of chi square tests showed that there were 10 influencing factors with statistical significance. MCA showed that the most important factor affecting patients receiving the BCS was times of birth, followed by the age of patients, tumor histological grade and stage. Conclusion In patients with indications of breast conserving therapy, the proportion of BCS was relatively low, so we may make relevant policies to improve the breast conserving therapy according to the influencing factors obtained in this paper. It is suggested that we should improve the level of operation and communication between doctors and patients, increase the promotion of BCS, and improve the prognosis and quality of life of early breast cancer patients.
