CD68 and urinary bladder carcinoma: Furthermore, subgroup analyses according to the CD68+ TAMs in different sample locations also showed that the high CD68+ TAMs infiltration presented no significant correlation with RFS in bladder cancer patients with regard to whole sample area (or not specified) (HR = 1.06, 95% CI = 0.58 ~ 1.53) (Figure 3, Location = whole), tumor stroma (HR = 1.00, 95% CI = 0.91 ~ 1.10) (Figure 3, Location = stroma) and tumor islet (HR = 1.00, 95% CI = 0.97 ~ 1.02) (Figure 3, Location = intratumor).
