For indexes such as CCL11/CA 19-9, log CCL11/CA 19-9, log CCL24/CA 19-9 and CCR3/CA 19-9, we observed statistically significant differences only when comparing the control group and the group with low levels of cancer development (locally limited), which may indicate the possibility of the detection of early-stages changes in the course of neoplastic disease. The gene discussed is CCR3; the disease is neoplasm.
