Notably, a decreased expression of hsa_circ_0045881 was shown to be associated with a large tumour size (p = 0.043), advanced TNM stage (p = 0.015), high Ki-67 proportion (> 20%) (p = 0.002), increased lymphatic metastasis (p = 0.029) and death in individuals (p = 0.006) with TNBC (Table 2). The gene discussed is MKI67; the disease is neoplasm.
