A team at Weill Cornell Medical College in New York that is studying ovarian cancer has not only discovered another mechanism by which tumors evade attack by the immune system, but is also devising a first-in-class potential treatment.

Study data reported at the 2015 ASCO Annual Meeting has demonstrated a nearly 20% response rate with the anti-programmed cell death-1 (PD-1) monoclonal antibody nivolumab (Opdivo) in patients with HCC.
