A Strong B-cell Response Is Part of the Immune Landscape in Human High-Grade Serous Ovarian Metastases

Purpose: In high-grade serous ovarian cancer (HGSOC), higher densities of both B cells and the CD8+ T-cell infiltrate were associated with a better prognosis. However, the precise role of B cells in the antitumor response remains unknown. As peritoneal metastases are often responsible for relapse, our aim was to characterize the role of B cells in the antitumor immune response in HGSOC metastases. Experimental Design: Unmatched pre and...
