Non-doctoral factors influencing the surgical choice of Chinese patients with breast cancer who were eligible for breast-conserving surgery

BackgroundThe rate of breast-conserving surgery (BCS) is low in China. Many patients choose mastectomy even when informed that there is no difference in the overall survival rate compared with that of BCS plus radiotherapy. This study aimed to investigate the factors that influenced the surgical choice in patients eligible for BCS.MethodsFemale patients with breast carcinoma were enrolled in a single center from March 2016 to January 2017. They made their own decision regarding the surgical approach. Univariate analysis was employed to determine the factors associated with the different breast surgical approaches. Significant factors (defined as P<0.05) were then incorporated into multivariate logistic regression models to determine the factors that independently influenced patients' decision.ResultsOf the 271 patients included, 149 were eligible for BCS; 65 chose BCS and 84 chose mastectomy. On the basis of univariate analysis, patients with younger age, higher income and education, shorter admission to surgery interval, and shorter confirmed diagnosis to surgery interval were more likely to choose BCS than mastectomy (P<0.05). Meanwhile, patients who resided in rural regions, did not have general medicare insurance, and were diagnosed with breast cancer preoperatively were more inclined to choose mastectomy than BCS (P<0.05). The multivariate model revealed three independent influencing factors: age at diagnosis (P=0.009), insurance status (P=0.035), and confirmed diagnosis to surgery interval (P=0.037). In addition, patients receiving neoadjuvant chemotherapy (NCT) were more inclined to choose mastectomy.ConclusionSurgical choice of patients eligible for BCS was affected by several factors, and age at diagnosis, confirmed diagnosis to surgery interval, and insurance status were independent factors.
