Abstract:
Objective: To explore the relationship between ERCC 1, Ki67, PCNA expression with anthracycline chemotherapeutic drugs′sensitivities in breast cancer tissues.Methods:The ERCC1,Ki67,PCNA expression in 93 breast cancer tissue was detected by immunohistochemical staining.The efficacy of chemotherapy was observed and the difference of anthracycline chemotherapy effect among patients with different ERCC 1,Ki67,PCNA expression was compared.Results:The positive rate of ERCC1 was 65.59%,the positive rate of Ki67 was 69.89%,the positive rate of PCNA was 64.52%.The total effective rate of ERCC 1-positive group was 50.82%,and ERCC1-negative group was 84.38%.In Ki67-positive group,the effective rate of patients in 25%-50%intensity was 73.68%, the effective rate of patients in 50%-75% intensity was 85.71%, the effective rate of patients in >75%intensity was 88.89%, and Ki67-negative group was 60.71%.In PCNA-positive group , the effective rate of patients in 25%-50%intensity was 52.94%, the effective rate of patients in 50%-75% intensity was 62.07%, the effective rate of patients in >75%intensity was 71.43%, and PCNA-negative group was 81.82%.These differences were all statistically significant ( P<0.01 ,P<0.05 , P<0.05).Conclusion: There are correlations between ERCC1,Ki67,PCNA expression with anthracycline chemotherapeutic drugs′sensitivity of patients with breast cancer.Combined detection of multi-factor in clinical is more helpful for the selection of chemotherapy drugs and the formulation of chemotherapy regimen.
