The positive rates of P53 expression in CNC and BLBC were 60.9% and 87.5%, respectively, and statistical differences were found between CNC and BLBC (p < 0.05); the high expression rates of Ki-67 in CNC and BLBC were 73.9% and 93.8%, respectively, and there were also statistical differences between the two (p < 0.05) (as depicted in Table 8). Here, TP53 is linked to Carney complex.
