Introduction: Clinical significance of tumor-infiltrating plasma cells and B-cells in lung adenocarcinoma is not
well known.
Methods: CD3, CD20 and MUM1 immunostains were performed on representative tumor blocks selected from
120 consecutive lung adenocarcinoma cases treated by surgical resection at Mayo Clinic Rochester. CD3+ T-cells,
CD20+ B-cells, and MUM1+ plasma cells were enumerated separately in the intraepithelial (IE) compartment and the
stroma (ST) by digital image analyses using whole sections. Measured tumor-infiltrating plasma cells and B-cells
were correlated with patient’s overall survival (OS) using Cox proportional hazards analysis.
Results: Median age of patients was 69 years (range, 46-91 years) and 52 were male. Median numbers
