Abstract:

Topoisomerase Ⅱα(TOP2A)is considered as a key nuclease in DNA replication and transcription. It is a proliferation marker of tumor cells and an important target of anthracyclines, which plays an important role in biological process. Many studies have shown that TOP2A gene amplification is related closely to the efficacy of anthracyclines. However, the effect of TOP2A protein expression on the prediction of anthracycline efficacy and the prognosis of breast cancer patients remains controversial. Our study reviewed the predictive and prognostic value of TOP2A protein.

Key words: Breast neoplasms, DNA topoisomerases, type Ⅱ, Anthracyclines, Prognosis
