- Abstract: Objective To explore the predictive factors of axillary lymph node metastasis in breast cancer,and to provide a basis for clinical decision-making under the DIP payment mode of medical insurance.Methods A total of 715 patients with breast cancer were divided into the metastasis group(n=309)and the non-metastasis group(n=406)according to the postoperative paraffin pathological results.Data of age＞60 years old,menopausal status,body mass index(BMI)＞24 kg/m2,hyperglycemia(GLU＞6.1 mmol/L),high triglycerides(TG＞1.7 mmol/L),maximum diameter of the tumor,the distance between the tumor and nipple and the quadrant where the tumor located were compared between the two groups.The expression levels of estrogen receptor(ER),progesterone receptor(PR),nuclear proliferation antigen(Ki-67)and human epidermal growth factor receptor-2(Her-2)in breast cancer tissue samples were detected by histological grading and immunohistochemistry.The consistency,sensitivity and specificity of chest CT and breast ultrasound were examined,taken the pathological diagnosis as the gold standard.Results Compared with the non-metastatic group,the proportion of maximum diameter of tumor＞2 cm,histological grade Ⅲ,high Ki-67 and high ER expression,tumor located in the outer upper quadrant,the distance＞3 cm between tumor and nipple were increased in the metastatic group,and the proportion of high level of TG was decreased in the metastatic group(P＜0.05).The consistency between chest CT and pathological diagnosis was better than that of breast ultrasound(Kappa was 0.493 and 0.353 respectively,P＜0.05).Logistic regression analysis showed that histological grade Ⅲ,high expression of ER,maximum diameter of tumor＞2 cm,and chest CT diagnosis were risk factors for axillary lymph node metastasis(P＜0.05).Conclusion The combined application of the predictive factors of axillary lymph node metastasis of breast cancer could provide certain reference for clinical decision-making under the background of DIP payment mode of medical insurance.
