CCL8 and lip and oral cavity carcinoma: Specifically, increased levels of C-X-C motif chemokine ligand 9 (odd ratios [OR] = 0.760, 0.600–0.962, 95% confidence interval [CI] 0.600–0.962, P = .023), monocyte chemoattractant protein 1 (OR = 0.78, 95% CI 0.32–0.99, P = .046), and TNF related activation induced cytokine (OR = 0.792, 95% CI 0.630–0.994, P = .044) were associated with a reduced risk of oral cancer, while higher levels of monocyte chemoattractant protein 2 (OR = 1.164, 95% CI 1.001–1.353, P = .048) and CC motif chemokine 25 (OR = 1.434, 95% CI 1.106–1.858, P = .006) were linked to an increased risk.
