CCR3 and gastric cancer: The high expression levels of CCR1 (p = 0.00054), CCR2 (p = 0.008), CCR5 (p = 4.4e-06), CCR7 (6.4e-05), CCR8 (1.7e-05), CCR9 (p = 0.0022), and CCR10 (p = 5.2e-05) indicate shorter PPS, whereas the high expression levels of CCR3 (p = 0.00053) and CCR6 (p = 0.035) indicate longer PPS in GC cases.
