MKI67 and neoplasm: SST5 and CXCR4 as well as Ki-67 expression intensities significantly correlated with tumor grading (SST5: τ = 0.178, p = 0.007; CXCR4: τ = 0.256, p < 0.001; Ki-67: τ = 0.894, p < 0.001), whereas a negative correlation was noted between SST2A and CgA expression intensities and tumor grading (SST2A: τ = −0.281, p < 0.001; CgA: τ = −0.313, p < 0.005), or tumor size (SST2A: τ = −0.204, p = 0.005; CgA: τ = −0.208, p = 0.005).
