The results demonstrated significant negative correlations between LRP1 levels and the infiltration levels of B cells in six cancer types, including OC (r = −0.325, p < 0.001), BLCA (r = −0.160, p < 0.05), GBM (r = −0.249, p < 0.001), THCA (r  = −0.173, p  <  0.001), KIRC (r  =  −0.188, p  <  0.001), and KICH (r  =  −0.188, p  <  0.001). This evidence concerns the gene LRP1 and cancer.
