Abstract: 【Objective】 To investigate the clinicopathological characteristics of non-specific invasive breast cancer (IBC-NST) and the relationship between ipsilateral axillary lymph node metastasis and Ki-67 expression. 【Methods】 A total of 101 patients with IBC-NST were retrospectivily recruited and divided into two groups with high expression of Ki-67 (70cases) and low expression of Ki-67 (31cases). The χ² test and Kruskal-Wallis H test were used to compare the clinical and pathological characteristics and other count data of patients between the groups. The comparison of ultrasound diagnosis of ipsilateral axillary lymph node metastasis and pathological results was calculated using correlation values such as sensitivity and specificity. The correlation between ipsilateral axillary lymph node metastasis and Ki-67 expression was analyzed with Spearman correlation analysis. 【Results】 In different Ki-67 expression groups, the size of tumor mass, histological grade of breast cancer, and clinical stage were statistically different between Ki-67 expression groups (P<0.05). The positive expression rate of tumor mass ≥2 cm (58.57%), histological grade Ⅲ (32.86%), clinical stages Ⅲ (34.29%) and Ⅳ (5.71%) was higher in the Ki-67 high expression group; ipsilateral axillary lymph node metastasis and Ki-67 high expression were positively correlated (r=0.393, P<0.05). 【Conclusion】 In IBC-NST cases, the tumor mass ≥ 2 cm, histological grade Ⅲ, clinical stage Ⅲ, and Ⅳ are correlated with the high expression of Ki-67. At the same time, ipsilateral axillary lymph node metastasis and Ki-67 high expression are positively correlated, which provides reference for IBC-NST proliferation assessment and clinical intervention.
