CD27 and endometrial cancer: But all possible factors in B cell panel, namely, CD38 on IgD+ CD24- B cell (OR=1.286, 95%CI; 1.038-1.594, P=0.021), IgD on IgD+ CD24- B cell (OR=1.09, 95%CI; 1-1.188, P=0.049), IgD on IgD+ CD38dim B cell (OR=1.096, 95%CI; 1.001-1.199, P=0.046), BAFF-R on IgD+ CD24+ B cell (OR=1.219, 95%CI; 1.003-1.483, P=0.047), BAFF-R on IgD- CD24- B cell (OR=1.249, 95%CI; 1.019-1.532, P=0.032), BAFF-R on IgD- CD27- B cell (OR=1.249, 95%CI; 1.02-1.529, P=0.032), BAFF-R on IgD- CD38+ B cell (OR=1.915, 95%CI; 1.12-3.273, P=0.018) were correlated with increased risk of endometrial cancer.
