In line with reports that the size of the tumor-infiltrating neutrophil (TIN) pool is implicated in cancer aggression and is touted as a useful predictor of chemotherapy responses or prognosis in different cancer types [21], we observed that TIN exhibited partial correlations of 0.16 (p = 1.59 × 10−3) and 0.19 (p = 1.42 × 10−4) with GSE1 and TACSTD2 expression levels, respectively (Figure 4G). Here, TACSTD2 is linked to cancer.
