CXCL12 and neoplasm: Significant differences between the two groups were also found for tumor size (6.3 ± 1.5 vs. 11.0 ± 1.1, p = 0.035), Weiss score (4.3 ± 0.6 vs. 6.7 ± 0.4, p = 0.002), and age (38.3 ± 4.6 vs. 53.1 ± 3.8, p = 0.041), with the CXCL12 low-expressing group showing worse parameters (Table 1).
