A multi-institutional team led by scientists from the Medical College of Wisconsin Cancer Center has discovered PD-L2 as a therapy-relevant marker to identify patients with estrogen receptor-positive breast cancer who may benefit from new immunotherapies.
In patients with high-risk HER2-positive breast cancer, post-surgery, or adjuvant, treatment with trastuzumab emtansine, also referred to as T-DM1) reduced the long-term risk of death or invasive disease by 46% and improved survival compared to trastuzumab alone, according to the final results of the phase III KATHERINE clinical trial led by researchers from the University of Pittsburgh and UPMC Hillman Cancer Center.
