The high expression levels of CCR4 (p = 0.00065), CCR5 (p = 0.019), CCR7 (p = 0.016), CCR8 (p = 0.00041), CCR9 (p = 0.00014), and CCR10 (p = 0.00017) indicate shorter OS, while the high expression levels of CCR3 (p = 0.0069) and CCR6 (p = 0.0032) indicate a longer OS in GC patients. Here, CCR3 is linked to gastric cancer.
