Classifying Cancers Based on T-cell Infiltration and PD-L1
Cet article passe en revue les travaux récents sur l'intérêt de détecter la présence ou l'absence de lymphocytes infiltrant les tumeurs et de mesurer l'expression de PD-L1 dans le micro-environnement tumoral pour évaluer des combinaisons d'immunothérapies
Cancer immunotherapy may become a major treatment backbone in many cancers over the next decade. There are numerous immune cell types found in cancers and many components of an immune reaction to cancer. Thus, the tumor has many strategies to evade an immune response. It has been proposed that four different types of tumor microenvironment exist based on the presence or absence of tumor-infiltrating lymphocytes and programmed death-ligand 1 (PD-L1) expression. We review this stratification and the latest in a series of results that shed light on new approaches for rationally designing ideal combination cancer therapies based on tumor immunology.
