PURPOSE: Ovarian cancer often progresses by disseminating to the peritoneal cavity, but how the tumor cells evade host immunity during this process is poorly understood. Programmed cell death 1 ligand 1 (PD-L1) is known to suppress immune system and to be expressed in cancer cells. The purpose of this study is to elucidate the function of PD-L1 in peritoneal dissemination. EXPERIMENTAL DESIGN: Ovarian cancer cases were studied by microarray and immunohistochemistry. PD-L1 expression in mouse ova  ...[more]
