Expression of FoxM1 and BCRP in invasive breast carcinoma of no special type and its prognosis significance / 中华病理学杂志

ABSTRACT

Objective@#To investigate the relationship between expression of FoxM1 and BCRP in invasive breast carcinoma of no special type (IBC-NST) tissues and the clinical pathological characteristics and prognosis of the patients.@*Methods@#Seventy-eight cases of IBC-NST with excision were included. The expression of FoxM1 and BCRP was assessed by immunohistochemistry and its relationship with the clinical pathological characteristics and prognosis was evaluated.@*Results@#FoxM1 was expressed in 71.8%(56/78) of IBC-NST, and the expression was related to tumor diameter, TNM staging, ER, PR and HER2. BCRP was expressed in 53.8% (42/78) of IBC-NST, and the expression was related to age, tumor diameter, lymph node metastasis, ER and HER2. Kaplan-Meier survival analysis showed the survival time was related to tumor diameter, TNM staging, lymph node metastasis and the expression of FoxM1, BCRP, ER, PR and HER2. Cox multivariate analysis showed that TNM staging, FoxM1, BCRP, HER2 were determinants of patient survival time.@*Conclusions@#The expression of FoxM1 is associated with tumor diameter, TNM staging, ER, PR and HER2 while BCRP is associated with age, tumor diameter, lymph node metastasis, ER and HER2. Both FoxM1 and BCRP have prognostic significance in IBC-NST patients.
