Title:

[Effect of progesterone receptor status on efficacy of aromatase inhibitors and survival time in patients with advanced breast cancer]

Published date:

Excerpt:
The median progression-free survival time ((PFS)) of PR+ and PR- patients were 12.5 months and 9.0 months, respectively, and the difference was statistically significant (P=0.004). The clinical benefit rate (CBR) was 81.1% and 63.1%, respectively...PR+ type breast cancer has a better response to first-line AI endocrine therapy and longer PFS time than PR- type advanced breast cancer.
