Tumor-Infiltrating Plasma Cells Are Associated with Tertiary Lymphoid Structures, Cytolytic T-Cell Responses, and Superior Prognosis in Ovarian Cancer

Abstract
Purpose: CD8+ tumor-infiltrating lymphocytes (TIL) are key mediators of antitumor immunity and are strongly associated with survival in virtually all solid tumors. However, the prognostic effect of CD8+ TIL is markedly higher in the presence of CD20+ B cells, suggesting that cooperative interactions between these lymphocyte subsets lead to more potent antitumor immunity.
