Whereas plasma AIMP1 (r = −0.0506, p = 0.52), GARS1 (r = 0.0838, p = 0.286) and IL-10 (r = 0.0683, p = 0.385) did not show a meaningful r value, representing a noncorrelation with tumor size, the r value of plasma KARS1 (r = 0.2183, p = 0.005), CEA (r = 0.1084, p = 0.167) and CA 19-9 (r = 0.2322, p = 0.003) showed a positive correlation to tumor size (Figure 2B–D, Figure S2 and Table S3). The gene discussed is CEACAM5; the disease is neoplasm.
